**BACKGROUND OF THE INVENTION****[0002] 1. Field of the Invention**  
[0003] The present invention is directed to pharmaceutical and/or
dietary supplement compositions and methods of treating
neuromuscular and other diseases, including but not limited to
fibromyalgia, multiple sclerosis, muscular dystrophy, Alzheimer's,
dementia, amyotrophic lateral sclerosis, depression, and/or
rheumatoid arthritis. The present invention also encompasses
pharmaceutical and/or dietary supplement compositions and methods
of treating other physical ailments and disorders, including but
not limited to pain, fatigue, sleeplessness, loss of fine motor
control, speech loss, inflexibility, lyme disease, lyme disease
co-infection, gastroparesis (GP), myopathy, chronic inflammation
and/or incontinence. The method typically comprises administration
to a subject in need thereof an anhydrous copper complex of
formula C12H10ClCuN2O4. The invention also generally relates to
pharmaceutical treatment regimes and methods of making the
anhydrous copper complex of the present invention.  
  
**[0004] 2. Discussion of the Background**  
[0005] A litany of human diseases and other ailments are
characterized by neuromuscular degeneration and muscle weakness.
The term aneuromuscular diseasea refers to disorders that
adversely affect muscle function and/or the control thereof by the
central nervous system (CNS). In general, neuromuscular diseases
encompass a wide range of physical ailments characterized by
impaired muscle function. The following (non-limiting) list of
conditions is generally recognized as neuromuscular diseases or
conditions: multiple sclerosis, muscular dystrophy, rheumatoid
arthritis, fibromyalgia, myopathy, inflammatory bowel disease
(IBD), incontinence, inflexibility, impaired fine motor skills,
and amyotrophic lateral sclerosis (aALSa or Lou Gehrig's disease).  
  
[0006] A stroke, formerly known as a cerebrovascular accident
(CVA), often results in severe neurological impairment.
Post-stroke, many individuals suffer one or more neurological
impairments including, but not limited to: loss of fine motor
control, paralysis, speech impairment/loss (aphasia and/or
dysarthria), altered smell, taste, hearing, or vision, ptosis,
ocular and facial muscle weakness, diminished reflexes, loss of
balance, altered heart rate, apraxia, loss of memory, and/or
confusion.  
  
[0007] Numerous therapeutic methodologies are presently available
for the treatment of neurological conditions such as the ones
listed above. Efficacious treatments have proven elusive, however,
and existing drugs with the most promise often exhibit the most
undesirable side effects.  
  
[0008] Two of the most prominent diseases associated with impaired
neurological function are MD, MS and RA. These diseases and
currently available treatments therefore, are discussed in greater
detail herein below.  
  
**Muscular Dystrophy**  
[0009] The term Muscular Dystrophy (MD) actually refers to a group
of diseases characterized by muscle weakness and/or impaired
muscle function. The specific diseases include, but are not
limited to Becker, Duchenne, and Emery-Dreifuss. Over 100
diseases, however, display symptoms similar to MD. All are
characterized by reduced muscle function and muscle weakness.  
  
[0010] No cure exists for MD and many of the related pathologies.
Physical and occupational therapy may help those afflicted with MD
manage life with the disease, but neither therapy ameliorates or
reverses the disease's underlying causes or symptoms. Antisense
oligonucleotides have shown promise as a treatment, but are costly
and difficult to obtain for many MD patients. As a result, a
significant need exists for a cost-effective, widely available
treatment for MD (and related pathologies).  
  
**Multiple Sclerosis**  
[0011] Multiple Sclerosis (MS) is an autoimmune disease diagnosed
in 350,000-500,000 people in the United States. The disease is
characterized by multiple areas of inflammation and scarring of
the myelin in the brain and spinal cord. Patients inflicted with
the disease exhibit varying degrees of neurological impairment
depending on the location and extent of the myelin scarring.
Typical MS symptoms include fatigue, weakness, spasticity, balance
problems, bladder and bowel problems, numbness, loss of vision,
tremors, and depression. Available treatments of MS generally only
alleviate symptoms or delay the progression of the disability.
Recently developed treatments for MS (including stem cell
implantation and gene therapy) appear to be only conservatory.
Consequently, improved approaches for the treatment of MS are
needed.  
  
**Rheumatoid Arthritis**  
[0012] Rheumatoid Arthritis (RA) is another troublesome disorder
associated with inflammation. It is signified by chronic
inflammation in the membrane lining (the synovium) of the joints
and/or other internal organs. These inflammatory cells can also
damage bone and cartilage. For example, a joint inflicted with RA
may lose its shape and alignment, which can result in the loss of
range of motion. RA is characterized by pain, stiffness, warmth,
redness and swelling in the joint, and other systemic symptoms
like fever, fatigue, and anemia. RA currently affects roughly 1%
of the entire U.S. population (approximately 2.2 million people).
The pathology of RA is not fully understood, although it has been
hypothesized to result from a cascade of aberrant immunological
reactions.  
  
[0013] In many cases, conventional treatments for RA have proven
inefficient. For example, RA responds only partially to
symptomatic medications such as corticosteroids and non-steroidal
anti-inflammatory drugs (NSAIDs). These medications have been
around since the 1950's, and possess a significant risk of
contraindications. Moreover, the therapeutic effects of
anti-rheumatic drugs (DMARDs) such as Methotrexate (MTX) are
frequently inconsistent and only temporary. The latest class of
abiologica DMARDs (including ENBRELA(r), REMICADEA(r), HUMIRAA(r), and
KINERETA(r)) have shown promising treatment results, but significant
concerns exist regarding their long term safety profile. For
example, studies have shown an association between the use of both
ENBRELA(r) or REMICADEA(r) and the development of lymphoma. Other
reports have demonstrated that patients treated with either drug
exacerbate their congestive heart failure and develop serious
infection and sepsis, and aggravate symptoms of MS and other
central nervous system problems. As with MS, a need exists for
more effective treatments of RA.  
  
**Lyme Disease**  
[0014] Lyme disease is a bacterial infection (borrelia
burgdorferi) spread by ticks. The number of reported cases of Lyme
disease, and the number of geographical areas in which it is
found, has been increasing. In addition to causing arthritis, lyme
disease can also cause heart, brain, and nerve problems. Early
symptoms include skin-rash, flu-like symptoms (.e.g. chills,
fever, swollen lymph nodes, headaches, fatigue, muscle
aches/pains, and joint pain). More advanced symptoms include nerve
problems and arthritis. Currently, there is no available vaccine
on the market in the US for lyme disease.  
  
**Lyme Disease Co-Infection**  
[0015] Often, ticks can become infected with multiple
disease-causing microbes, resulting in co-infection. This may be a
potential problem for humans, due to Borrelia burgdorferi, and
other harmful pathogens carried and transmitted by some ticks.
Possible co-infections with viruses such as lyme borreliosis,
anaplasmosis, babesiosis, or encephalitis may occur. It is not
known how co-infection may affect disease transmission and
progression, but may help in diagnosing and treating lyme and
other such diseases. Currently, there is no reliable and regular
treatment for lyme disease co-infection.  
  
**Gastroparesis**  
[0016] Gastroparesis is a condition characterizes by the inability
of the stomach to empty its contents, when there is no blockage
(obstruction). The cause of gastroparesis is not known. There is
some evidence that it may be caused by a disruption of nerve
signals to the stomach. The condition is a complication of
diabetes and of some surgeries. Risk factors associated with
gastroparesis may include diabetes, gastrectomy (surgery to remove
part of the stomach), systemic sclerosis, use of medication that
blocks certain nerve signals (anticholinergic medication).
Symptoms may include abdominal distention, hypoglycemia (in people
with diabetes), nausea, premature abdominal fullness after meals,
weight loss, and vomiting. If gastroparesis is caused by a
condition that is reversible (e.g. pancreatitis), when the
condition is resolved, the symptoms will subside. For some
diabetics, better control of their blood sugar can also improve
the symptoms. If there is no reversible cause, gastroparesis
rarely resolves itself and the symptoms often grow more sever with
time. When accompanied by motility disorders of the muscles of the
small intestine, gastroparesis is particularly difficult to treat.  
  
**SUMMARY OF THE INVENTION**  
[0017] The objective of the present invention is to provide
pharmaceutical and/or dietary supplement compositions and methods
of making and using the same to treat and reduce many of the
symptoms of several diseases. The compositions contain an active
pharmacological ingredient comprised of a novel anhydrous copper
complex of formula C12H10ClCuN2O4. The pharmacologically active
ingredient may be administered alone or in combination with
additional active or inert agents or therapies (e.g. other
anti-inflammatory agents, diluents, and/or excipients).

[0036] Optionally, the compositions of the present invention are
used in combination with additional active or inert agents or
alternative therapies (e.g. other anti-inflammatory agents,
diluents, and/or excipients). In a preferred embodiment, the
alternative therapy is ozone therapy. Preferably, use of the
compositions of the present invention enhances the effectiveness
of the alternative therapy.  
  
Preparations and Administrations:  
  
[0037] The invention may be used to treat an animal with a disease
or physical ailment or disorder including, but not limited to, one
or more of the following: fibromyalgia, multiple sclerosis,
muscular dystrophy, rheumatoid arthritis, Alzheimer's, dementia,
ALS, depression, pain, fatigue, sleeplessness, inflexibility,
myopathy, lyme disease, lyme disease co-infection, gastroparesis
(GP), chronic inflammation, incontinence, impaired fine motor
skills, high cholesterol, low sperm count, obesity, alopecia,
burns, stretch marks, scars, ADD, ADHD, and/or erectile
dysfunction, wherein it is preferable that the animal is a mammal
and more preferable that the mammal is a human.  
  
[0038] Formula I is comprised of an anhydrous chlorobis copper I
complex (nicotinic acid). Preferably, the pharmaceutical
composition containing an effective amount of Formula I further
comprises copper ascorbate (esterified Vitamin C), ascorbic acid
(Vitamin C), and/or a pharmaceutically acceptable excipient
(carrier). More preferably, the pharmaceutically acceptable
carrier is an inert diluent.  
  
[0039] Frequency of dosage may vary depending on the purity of the
compound and the particular disease or physical ailment treated.
However, for treatment of most diseases and physical ailments, a
dosage regimen of (4) 2.5 mg capsules (for a total of 10 mg/day)
containing Formula I is preferred. As will be understood by one
skilled in the art, however, the optimal dosage level for a
particular subject will vary depending on a plurality of factors
including the potency and activity of the pharmacologically active
ingredient (e.g., Formula I), as well as the age, body weight,
general health, sex, diet, time of administration, route of
administration and rate of excretion, drug combination (if any)
and the severity of the particular disease or physical ailment
undergoing therapy. Subject to the above factors, a generally
effective amount of Formula I is between 1 mg and 20 mg per day.
More preferably, the effective amount of Formula I is between 5 mg
and 10 mg per day. Advantageously, the effective amount of Formula
I is between 7.5 mg to 10 mg per day. Most preferably (subject to
the factors listed above), the effective amount of Formula I is 10
mg/per day.  
  
[0040] Formula I may also comprise a component of an overall
pharmaceutical treatment regime for reducing and/or treating a
disease or physical ailment or other disorder including, but not
limited to: fibromyalgia, multiple sclerosis, muscular dystrophy,
rheumatoid arthritis, Alzheimer's, dementia, ALS, depression,
pain, fatigue, sleeplessness, inflexibility, myopathy,
incontinence, impaired fine motor skills, high cholesterol, low
sperm count, obesity, alopecia, burns, stretch marks, scars, ADD,
ADHD, and/or erectile dysfunction, the treatment regime
comprising: administering to a subject at the least the following
pharmacologically active ingredient(s) within a 24-hour period: a
compound of Formula I, and optionally a pharmaceutically
acceptable carrier, wherein the pharmacologically active
ingredient(s) is in an amount sufficient to reduce the symptoms of
the ailment.  
  
[0041] Optionally, the pharmaceutical treatment regime including
Formula I may include (or be combined with) additional
pharmacologically active ingredients or other complementary
treatments in order to provide synergistic therapeutic effects.
For example, Formula I may be administered in combination with
additional pharmacologically active agents including, but not
limited to, non-steroidal anti-inflammatory drugs (NSAIDs),
corticosteroids, disease modifying anti-rheumatic drugs (DMARDs),
biologic DMARDs, and/or cyclooxygenase-2 (COX-2) inhibitors. In a
preferred embodiment, Formula I is administered in combination
with ozone therapy.  
  
[0042] The pharmaceutical and/or dietary supplement compositions
(containing Formula I) of the present invention may take a variety
of forms specially adapted to the chosen route of administration.
The compositions may be administered orally, topically,
parenterally, by inhalation or spray, or by any other conventional
means. Preferably, the compositions are prepared and administered
in dosage unit formulations containing conventional non-toxic
pharmaceutically acceptable carriers, adjuvants and vehicles. In
one preferred embodiment, the composition is administered
sublingually. It is further understood that the preferred method
of administration may be a combination of methods. Oral
administration in the form of a capsule, pill, elixir, syrup,
lozenge, troche, or the like is particularly preferred. The
pharmaceutical compositions of the present invention (containing
Formula I) are preferably in a form suitable for oral use, for
example, as tablets, troches, lozenges, aqueous or oily
suspensions, dispersible powders or granules, emulsion, hard or
softgel capsules, or syrups or elixirs.  
  
[0043] Compositions intended for oral use may be prepared
according to any method known in the art for manufacture of
pharmaceutical compositions, and such compositions may contain one
or more agents selected from the group consisting of sweetening
agents, flavoring agents, coloring agents and preserving agents in
order to provide pharmaceutically elegant and palatable
preparations. Tablets may contain the active ingredient in
admixture with non-toxic pharmaceutically acceptable excipients
suitable for the manufacture of tablets. Such excipients may
include, for example, inert diluents, such as calcium carbonate,
sodium carbonate, lactose, calcium phosphate or sodium phosphate;
granulating and disintegrating agents, for example, corn starch,
or alginic acid; binding agents, for example starch, gelatin or
acacia; and lubricating agents, for example magnesium stearate,
stearic acid or talc. The tablets may be uncoated or they may be
coated by techniques to delay disintegration and absorption in the
gastrointestinal tract and thereby provide a sustained action over
a longer period. For example, a time delay material such as
glyceryl monostearate or glyceryl distearate may be utilized.  
  
[0044] Formulations for oral use may also be presented as hard
gelatin capsules wherein the active ingredient is mixed with an
inert solid diluent, for example, calcium carbonate, calcium
phosphate or kaolin, or as soft gelatin capsules wherein the
active ingredient is mixed with water or an oil medium, for
example peanut oil, liquid paraffin or olive oil.  
  
[0045] Aqueous suspensions contain the active materials in
admixture with excipients suitable for the manufacture of aqueous
suspensions. Such excipients are suspending agents, for example
sodium carboxymethylcellulose, methylcellulose,
hydroxypropylmethylcellulose, sodium alginate,
polyvinylpyrrolidone, gum tragacanth and gum acacia; and
dispersing or wetting agents, which may be a naturally-occurring
phosphatide, for example, lecithin, or condensation products of
ethylene oxide with long chain aliphatic alcoholsafor example,
heptadecaethyleneoxycetanol, or condensation products of ethylene
oxide with partial esters derived from fatty acids and hexitol
anhydrides, for example polyethylene sorbitan monooleate. The
aqueous suspensions may also contain one or more preservatives,
for example ethyl, or n-propyl-p-hydroxybenzoate, one or more
coloring agents, one or more flavoring agents, and one or more
sweetening agents, such as sucrose or saccharin.  
  
[0046] Oily suspensions may be formulated by suspending the active
ingredients in a vegetable oil, for example arachis oil, olive
oil, sesame oil or coconut oil, or in a mineral oil such as liquid
paraffin. The oily suspensions may contain a thickening agent, for
example beeswax, hard paraffin or cetyl alcohol. Sweetening agents
such as those set forth above, and flavoring agents may be added
to provide palatable oral preparations. These compositions may be
preserved by the addition of an anti-oxidant such as ascorbic acid
and/or copper ascorbate.  
  
[0047] Dispersible powders and granules suitable for preparation
of an aqueous suspension by the addition of water provide the
active ingredient (Formula I) in admixture with a dispersing or
wetting agent, suspending agent and one or more preservatives.
Suitable dispersing or wetting agents and suspending agents are
exemplified by those already mentioned above. Additional
excipients, for example sweetening, flavoring and coloring agents,
may also be present.  
  
[0048] Pharmaceutical compositions of the invention may also be in
the form of oil-in-water emulsions. The oily phase may be a
vegetable oil, for example olive oil or arachis oil, or a mineral
oil, for example liquid paraffin or mixtures of these. Suitable
emulsifying agents may be naturally occurring gums, for example
gum acacia or gum tragacanth; naturally-occurring phosphatide, for
example soy bean, lecithin, and esters or partial esters derived
from fatty acids and hexitol; anhydrides, for example sorbitan
monooleate; and condensation products of the said partial esters
with ethylene oxide, for example polyoxyethylene sorbitan
monooleate. The emulsions may also contain sweetening and
flavoring agents.  
  
[0049] Syrups and elixirs may be formulated with sweetening
agents, for example glycerol, propylene glycol, sorbitol or
sucrose. Such formulations may also contain a demulcent, a
preservative, and flavoring or coloring agents. The pharmaceutical
compositions may be in the form of a sterile injectable aqueous or
oleaginous suspension. This suspension may be formulated according
to the known art using those suitable dispersing or wetting agents
and suspending agents, which have been mentioned above. The
sterile injectable preparation may also be a sterile injectable
solution or suspension in a non-toxic parenterally acceptable
diluent or solvent, for example as a solution in 1,3-butanediol.
Among the acceptable vehicles and solvents that may be employed
are water, Ringer's solution and isotonic sodium chloride
solution. In addition, sterile, fixed oils are conventionally
employed as a solvent or suspending medium. For this purpose any
bland fixed oil may be employed including synthetic mono- and
diglycerides. In addition, fatty acids such as oleic acid find use
in the preparation of injectables.  
  
[0050] Alternatively, the compositions can be administered
parenterally in a sterile medium. Formula I, depending on the
vehicle and concentration used, can either be suspended or
dissolved in the vehicle. Advantageously, adjuvants such as local
anesthetics, preservatives and buffering agents can be dissolved
in the vehicle.  
  
[0051] For administration to non-human animals, the composition
containing Formula I may be added to the animal's feed or drinking
water. Optionally, one skilled in the art will recognize that
animal feed and drinking products may be formulated such that the
animal takes in an effective amount of Formula I via their diet.
For example, Formula I may constitute a component of a premix
formulated for addition to the feed or drinking water of an
animal. Compositions containing Formula I may also be formulated
as food or drink supplements for humans.  
  
[0052] Preferred embodiments of compositions containing Formula I
will have desirable pharmacological properties that include, but
are not limited to, oral bioavailability, low toxicity, and
desirable in vitro and in vivo half-lives. The half-life of
Formula I is inversely proportional to the frequency of dosage of
Formula I.  
  
[0053] It is to be understood that the foregoing describes
preferred embodiments of the present invention and that
modifications may be made thereto without departing from the scope
or spirit of the present invention as set forth in the claims.
Such scope is limited only by the claims below as read in
connection with the above specification. Many additional
advantages of applicant's invention will be apparent to those
skilled in the art from the descriptions, drawings, and the claims
set forth herein.  
  
Representative Elemental and SEM Analysis  
  
[0054] The following Tables (1-2) illustrate the results of an
elemental analysis of a composition comprising Formula I. The
elemental analysis depicts only one preferred embodiment of the
invention and is no way intended to limit the scope of the
invention.

[0055] As indicated in Tables 1-2, a representative sample of
Formula I comprises 15.73% copper. Given this data, one can
calculate the amount of copper in a particular dose of Formula I.
For example, a 2.5 mg dose (i.e. one capsule) yields 0.39 mg of
copper. Similarly, a 10 mg dose (the preferred dose) yields 1.57
mg of copper. As will be readily apparent to one skilled in the
art, however, the actual percentage of copper present in any given
sample of Formula I will vary depending on a number of factors
including, but not limited to, the purity, consistency and source
of the sample, as well as the synthetic methodology employed to
obtain the sample.  
  
[0056] FIGS. 1-9 depict data and imagery obtained from Scanning
Electron Microscope (SEM) and spectrometer analysis of a preferred
embodiment of the present invention. As shown in FIG. 9, the
copper particles are approximately 1.4 micrometers (I1/4m) in size.  
  
**EXAMPLE****Preparation of Formula I****[0057] Those skilled in the art will recognize various
synthetic methodologies that may be employed to prepare
non-toxic pharmaceutically acceptable compositions of Formula I.
One such (representative) example is set forth below:****[0058] A 3 L 3-neck round bottomed flask equipped with a
mechanical stirrer, reflux condenser and a solid addition funnel
was charged with nicotinic acid (131.61 g, 1.07 mol), ascorbic
acid (21.4 g, 0.12 mol) and 90% aqueous ethanol (2 L) then
placed in an appropriately sized heating mantle. The resultant
white suspension was stirred and heated gently to 45A deg C. and
cuprous chloride (35.2 g 0.36 mol) was introduced via the
addition funnel over 15 minutes while maintaining an inert
atmosphere of Nitrogen throughout the system. During previous
experiment attempts, an ethanolic suspension of cuprous chloride
was introduced to the reaction mixture as described in Patent
Application WO/2010/009739, however, partial oxidation to Copper
(II) chloride was observed during addition. To avoid such
oxidation, the cuprous chloride was added via the aforementioned
ascrew-mechanisma solid addition funnel and no oxidation to
Copper (II) chloride was observed. The mixture was then placed
under reflux and stirring was continued for a further 4.5 hours.
Heating under reflux conditions was maintained for 4.5 hours
rather than the recommended 5 minutes to ensure complete
complexation. Previous experiment attempts had shown incomplete
reaction following just 5 minutes of stirring. Upon cooling to
50A deg C., the mixture was filtered under suction and the red
filter cake was washed with aqueous ascorbic acid 5% w/v
solution (400 mL), ethanol 90% (400 mL) and then acetone (100
mL). The red filter cake was then collected and dried en vacuo
to afford a red solid (123 g).**

Applicant: C LAB PHARMA INTERNATIONAL  
  
The present invention is directed to a pharmaceutical and/or
dietary supplement composition comprising an effective amount of a
copper (I) complex with glycine, pyruvate, or succinic acid and
methods of treating mitochondrial, neuromuscular, and other
diseases. Also provided are pharmaceutical treatment regimes and
kits comprising a copper (I) complex with glycine, pyruvate, or
succinate.  
  
**RELATED APPLICATION DATA**  
[0001] This application is a continuation in-part of U.S. patent
application Ser. No. 14/773,289, filed on Sep. 4, 2015, which is
the U.S. national-stage application of International Application
No. PCT/US2014/021772, filed on Mar. 7, 2014, which claims the
benefit of U.S. Provisional Application No. 61/774,543, filed on
Mar. 7, 2013, the contents of each of which are hereby
incorporated by reference in its entirety.  
  
**TECHNICAL FIELD**  
[0002] This application relates to pharmaceutical and/or dietary
supplement compositions comprising copper (I) complexes and the
methods of preparing such copper (I) complexes. The application
also encompasses methods of treating mitochondria, neuromuscular,
and other diseases, and pharmaceutical and/or dietary supplement
compositions and methods of treating other physical ailments and
disorders, including but not limited to pain, fatigue,
sleeplessness, loss of fine motor control, speech loss,
inflexibility, Lyme disease, Lyme disease co-infection,
gastroparesis (GP), myopathy, chronic inflammation and/or
incontinence.  
  
**BACKGROUND OF THE INVENTION**  
[0003] Copper (as copper amino acid chelate) plays a role in
transporting oxygen throughout the body. The production of
collagen, which determines the integrity of bones, skin,
cartilage, and tendons, is copper dependent. Copper is also
crucial for making melanin, which provides color to skin and hair.
Copper helps keep blood vessels elastic, is needed for the
formation of elastin, functions as an iron oxidizer, and is needed
for the proper functioning of vitamin C.  
  
[0004] Copper is also an important cofactor for metalloenzymes,
and is a necessary cofactor for superoxide dismutase (Beem J BIOL
CHEM 249:7298 (1974)). Copper has been shown to decrease in
individuals over 70 years of age and to be basically zero in
cataractous lenses (Swanson BIOCHEM BIPHY RES COMM 45:1488-96
(1971)). If copper is significantly decreased, superoxide
dismutase has been shown to have decreased function, thereby
hampering an important protective lens mechanism (Williams PEDIAT
RES 1:823 (1977)). For these and many other reasons, copper is
required for optimal human health.  
  
[0005] The two principal oxidation states of copper are +1 and +2
although some +3 complexes are known. Copper (I) compounds are
expected to be diamagnetic in nature and are usually colorless,
except where color results from charge transfer or from the anion.
The +1 ion has tetrahedral or square planar geometry. In solid
compounds, copper (I) is often the more stable state at moderate
temperatures.  
  
[0006] The copper (II) ion is usually the more stable state in
aqueous solutions. Compounds of this ion, often called cupric
compounds, are usually colored. They are affected by Jahn Teller
distortions and exhibit a wide range of stereochemistries with
four, five, and six coordination compounds predominating. The +2
ion often shows distorted tetrahedral geometry.  
  
[0007] Complexes of copper (I) are thought to have a unique
mechanism of action in promoting aerobic respiration via the
electron transport chain. By causing the mitochondria in the cells
to produce adenosine triphosphate (ATP) more efficiently and
avoiding the production of lactic acid and ethanol that
accompanies anaerobic respiration, pharmaceutical preparations and
dietary supplements with copper (I) may alleviate and treat many
illness and diseases. Among these diseases are those involving
neuromuscular degeneration and muscle weakness. Accordingly, there
is a need to develop novel copper (I) compounds that may stimulate
ATP production in the mitochondria.  
  
**SUMMARY OF THE INVENTION**  
[0008] The objective of the present invention is to provide
pharmaceutical and/or dietary supplement compositions and methods
of making and using the same to treat and reduce many of the
symptoms of several diseases. The compositions contain an active
pharmacological ingredient comprised of a copper (I) complex. The
pharmacologically active ingredient may be administered alone or
in combination with additional active or inert agents or therapies
(e.g. other anti-inflammatory agents, diluents, and/or
excipients).  
  
[0009] The pharmacologically active ingredient of the present
invention possesses a chemical structure selected from:  
  
[0010] The present invention is also directed to a method of
treating diseases and other physical ailments or disorders. In a
preferred embodiment the method comprises the step of

having a formula of Formula (I), Formula (II), Formula (III) or
Formula (IV) to reduce and/or treat a disease or physical ailment
or disorder. Preferably the disease or physical ailment being
treated is a mitochondrial or neuromuscular disease. The treated
diseases or disorders (or other physical ailments) include, but
are not limited to fibromyalgia, spinal cord injury, multiple
sclerosis, muscular dystrophy, stroke, rheumatoid arthritis, pain,
fatigue, sleeplessness, loss of fine motor control, speech loss,
inflexibility, Lyme disease, Lyme disease co-infection,
gastroparesis (GP), chronic inflammation, myopathy, chronic
inflammation, and/or incontinence. It is also preferable that the
subject be diagnosed with one of the diseases and/or disorders
prior to treatment.  
  
[0011] The present invention encompasses a method of treating a
mitochondrial disease selected from the group consisting of
Myoclonic Epilepsy with Ragged Red Fibers (MERRF); Mitochondrial
Myopathy, Encephalopathy, Lactacidosis, and Stroke (MELAS);
Diabetes mellitus and deafness (DAD); Maternally Inherited
Diabetes and Deafness (MIDD), Leber's Hereditary Optic Neuropathy
(LHON); chronic progressive external ophthalmoplegia (CPEO); Leigh
Disease; Kearns-Sayre Syndrome (KSS); Friedreich's Ataxia (FRDA);

pigmentosa, and ptosis (NARP); Myoneurogenic gastrointestinal
encephalopathy (MNGIE); Complex I Deficiency; Complex II
Deficiency; Complex III Deficiency; Complex IV Deficiency; Complex
V Deficiency; and other myopathies that effect mitochondrial
function.

[0031] Elements and facts in the figures are illustrated for
simplicity and have not necessarily been rendered according to any
particular sequence or embodiment.  
  
**DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS**  
[0032] The verb acomprisea as is used in this description and in
the claims and its conjugations are used in its non-limiting sense
to mean that items following the word are included, but items not
specifically mentioned are not excluded. In addition, reference to
an element by the indefinite article aaa or aana does not exclude
the possibility that more than one of the elements are present,
unless the context clearly requires that there is one and only one
of the elements. The indefinite article aaa or aana thus usually
means aat least one.a  
  
[0033] The terms acopper (I) complexa and acopper (I) compounda as
used herein are interchangeable and refer to a chemical compound
in which copper is present in its +1 oxidation state and interacts
with at least one other element through ionic or covalent bonding.  
  
[0034] The term aextended releasea herein refers to any
formulation or dosage form that comprises an active drug and which
is formulated to provide a longer duration of pharmacological
response after administration of the dosage form than is
ordinarily experienced after administration of a corresponding
immediate release formulation comprising the same drug in the same
amount. Controlled release formulations include, inter alia, those
formulations described elsewhere as acontrolled releasea, adelayed
releasea, asustained releasea, aprolonged releasea, aprogrammed
releasea, atime releasea and/or arate controlleda formulations or
dosage forms. Further for the purposes of this invention refers to
release of an active pharmaceutical agent over a prolonged period
of time, such as for example over a period of 8, 12, 16 or 24
hours.  
  
[0035] As used herein, the term asubjecta or apatienta refers to
any vertebrate including, without limitation, humans and other
primates (e.g., chimpanzees and other apes and monkey species),
farm animals (e.g., cattle, sheep, pigs, goats and horses),
domestic mammals (e.g., dogs and cats), laboratory animals (e.g.,
rodents such as mice, rats, and guinea pigs), and birds (e.g.,
domestic, wild and game birds such as chickens, turkeys and other
gallinaceous birds, ducks, geese, and the like). In some
embodiments, the subject is a mammal. In other embodiments, the
subject is a human.  
  
**Compositions**  
[0036] The compositions of the present invention may comprise an
effective amount of a copper (I) complex having a formula selected
from:  
  
Preferably, the pharmaceutical composition further comprises
copper ascorbate (esterified Vitamin C), ascorbic acid (Vitamin
C), and/or a pharmaceutically acceptable excipient (carrier). More
preferably, the pharmaceutically acceptable carrier is an inert
diluent.  
  
[0037] The compositions of the present invention may comprise a
delivery vehicle. Suitable delivery vehicles include a liposome, a
microsome, a nanosome, a picosome, a pellet, a granular matrix, a
bead, a microsphere, a nanoparticle formulation, or an aqueous
solution.  
  
[0038] Liposomes can aid in the delivery of the copper (I)
compounds to a particular tissue and can also increase the blood
half-life of the compounds. Liposomes suitable for use in the
invention are formed from standard vesicle-forming lipids, which
generally include neutral, positively or negatively charged
phospholipids and, optionally, a sterol, such as cholesterol. The
selection of lipids is generally guided by consideration of
factors such as the desired liposome size and half-life of the
liposomes in the blood stream. A variety of methods are known for
preparing liposomes, for example as described in Szoka et al.
(1980), Ann. Rev. Biophys. Bioeng. 9: 467; and U.S. Pat. Nos.
4,235,871, 4,501,728, 4,837,028, and 5,019,369, the entire
disclosures of which are herein incorporated by reference.  
  
[0039] Polyacrylates represent a further example of a suitable
delivery vehicle for use in the present invention. By way of
example, a terpolymer of styrene and hydroxyethyl methacrylate
cross-linked with a difunctional azo-compound may be employed. The
system depends on cleavage of the azo bond by intestinal
microflora resulting in degradation of polymer. Similarly, a pH
responsive poly (methacrylic-g-ethylene glycol) hydrogel may be
employed as an oral delivery vehicle. Once inside the basic and
neutral environment of the small intestine, the gels rapidly swell
and dissociate.  
  
[0040] In another embodiment, a microcapsule formulation may be
employed for peroral delivery. In more detail, aqueous colloidal
terpolymers of ethylacrylate/methyl methacrylate/2-hydroxylethyl
methacrylate (poly (EA/MME/HEMA), for example as synthesized by
emulsion polymerization technique(s) may be employed. These
polymers exhibit delayed release profiles, which were
characterized by a long lag time and subsequent rapid release of
the entrapped moiety.  
  
[0041] In another embodiment, orally administered nanoparticles
may serve as suitable delivery vehicles. By way of example, loaded
nanoparticles may be entrapped into pH sensitive microspheres,
which serve to deliver the incorporated nanoparticle to the
desired site of action. Nanoparticles have a large specific
surface, which is indicative of high interactive potential with
biological surfaces. Thus, bioadhesion can be induced by binding
nanoparticles with different molecules. By way of example,
nanoparticles may be prepared from gliadin protein isolate from
wheat gluten and then conjugated with lectins (glycoproteins of
non-immune origin which provide specific bioadhesion).
Accordingly, nanoparticles are provided, which have a high
capacity for non-specific interaction with intestine.  
  
[0042] The compositions of the present invention may take the form
of differently sized particles. In some embodiments, particles are
microparticles (aka microspheres or microsomes). In general, a
amicroparticlea refers to any particle having a diameter of less
than 1000 I1/4m. In some embodiments, particles are nanoparticles
(aka nanospheres or nanosomes). In general, a ananoparticlea
refers to any particle having a diameter of less than 1000 nm. In
some embodiments, particles are picoparticles (aka picospheres or
picosomes). In general, a apicoparticlea refers to any particle
having a diameter of less than 1 nm. In some embodiments,
particles are micelles.  
  
[0043] In one embodiment, a delivery vehicle based on an
albumin-chitosan mixed matrix microsphere-filled coated capsule
formulation may be employed. In this regard, a preparation of a
copper (I) compound of the invention is filled into hard gelatin
capsules and enteric coated.  
  
[0044] In one embodiment, albumin microspheres may be employed as
the oral delivery system.  
  
[0045] In one embodiment, squalane oil-containing multiple
emulsions may be employed.  
  
[0046] In one embodiment, poly(lactide-co-glycolide) microspheres
may be employed as the oral delivery vehicle.  
  
[0047] In one embodiment, a delivery coating comprising a mixture
of pH-responsive enteric polymer (Eudragit S) and biodegradable
polysaccharide (resistant starch) in a single layer matrix film
may be employed.  
  
[0048] In one embodiment, delivery capsules such as liposomes,
micro- or nanocapsules (e.g. chitosan nanocapsules) may be
chemically modified with poly(ethylene glycol) (PEG). The typical
degree of PEGylation is in the range of 0.1% to 5%, such as 0.5%
to 2%, for example 0.5% or 1%. The presence of PEG, whether alone
or grafted to chitosan, improves the stability of the delivery
capsules in the gastrointestinal fluids.  
  
[0049] PEGylated delivery vehicles such as liposomes, micro- or
nanocapsules have an intrinsic ability to accumulate at disease
sites and facilitate transfection of target cells. Unlike many
viral vectors, PEGylated liposomes are generally considered to be
non-immunogenic.  
  
[0050] In one embodiment, a branched PEGylating reagent is
employed as branched PEG protecting groups are more effective than
linear PEG molecules.  
  
[0051] In one embodiment, the copper (I) compounds of the
invention are prepared with carriers that will protect the
compound against rapid elimination from the body, such as an
extended release formulation, including implants and
microencapsulated delivery systems. Biodegradable, biocompatible
polymers can be used, such as ethylene vinyl acetate,
polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and
polylactic acid. Methods for preparation of such formulations will
be apparent to those skilled in the art. The materials can also be
obtained commercially from Alza Corporation and Nova
Pharmaceuticals, Inc.  
  
[0052] Other embodiments of the invention are directed to a single
crystalline form of the copper (I) complexes characterized by a
combination of the characteristics of any of the single
crystalline forms discussed herein. The characterization can be
any combination of one or more of the XRPD, TGA, DSC, moisture
sorption/desorption measurements and single crystal structure
determination described for a particular crystalline form. For
example, the single crystalline form of a copper (I) complex can
be characterized by any combination of the XRPD results regarding
the 2I, position of the major peaks in an XRPD scan; and/or any
combination of one or more of the unit cell parameters derived
from data obtained from the single crystal structure analysis. DSC
determinations of the temperature associated with the maximum heat
flow during a heat flow transition and/or the temperature at which
a sample begins to undergo a heat flow transition may also
characterize the crystalline form. Weight change in a sample
and/or change in sorption/desorption of water per molecule of a
copper (I) complex of the present invention as determined by
moisture sorption/desorption measurements over a range of relative
humidity can also characterize a single crystalline form of a
copper (I) complex.  
  
[0053] Examples of combinations of single crystalline form
characterizations using multiple analytical techniques include the
2I, positions of at least one of the major peaks of an XRPD scan
and the temperature associated with the maximum heat flow during
one or more heat flow transitions observed by a corresponding DSC
measurements; the 2I, positions of at least one of the major peaks
of an XRPD scan and one or more weight losses associated with a
sample over a designated temperature range in a corresponding TGA
measurement; the 2I, positions of at least one of the major peaks
of an XRPD scan, and the temperature associated with the maximum
heat flow during one or more heat flow transitions observed by a
corresponding DSC measurements, and one or more weight losses
associated with a sample over a designated temperature range in a
corresponding TGA measurement; the 2I, positions of at least one of
the major peaks of an XRPD scan, and the temperature associated
with the maximum heat flow during one or more heat flow
transitions observed by a corresponding DSC measurements, one or
more weight losses associated with a sample over a designated
temperature range in a corresponding TGA measurement, and the
change in sorption/desorption measurements over a range of
relative humidity. As well, each of the aforementioned examples
can replace the use of 2I, positions of at least one of the major
peaks of an XRPD scan with one or more unit cell parameters of the
single crystalline form.  
  
[0054] The combinations of characterization that are discussed
above can be used to describe any of the single crystalline forms
of a copper (I) complex of the present invention.  
  
[0055] The D90 particle size diameter of the copper (I) complexes
of the present invention may be 1 to 500 microns; e.g., any range
within 1 and 500 microns, such as 1 to 100 microns, 50 to 250
microns, 100 to 300 microns, 250 to 500 microns, etc.  
  
**Indications**  
[0056] The compositions of the present invention may be used to
effectively treat numerous human diseases and other ailments
characterized by neuromuscular degeneration and muscle weakness.
These diseases are described in detail below.  
  
[0057] The copper (I) complexes of the present invention are
particularly effective in treating mitochondrial diseases.
Mitochondrial diseases are often the result a deficiency in ATP
production, via the oxidative phosphorylation, which makes high
energy-demanding tissues or organs such as heart, brain, and
muscles, the main targets for these disorders. By restoring ATP
production to normal, the copper (I) complexes may prevent, treat,
or reverse mitochondrial disease.  
  
[0058] Impairments in oxidative phoshporylation are often referred
to as mitochondrial dysfunction (and are associated with
mitochondrial disease). They can result from hereditary and
somatic mutations in nuclear genes or mtDNA, or functional
impairments by drugs or toxins. Mutations in over 100 genes
constituting the oxidative phosphorylation machinery are linked
with mitochondrial encephalopathies in humans, which are the most
common metabolic diseases with an incidence of over 1/5000 in live
births.  
  
[0059] Respiratory chain Complex I deficiency is a cause of
mitochondrial diseases in many cases. Twenty-five of at least
fifty known genes implicated in Complex I biogenesis are found
associated with mitochondrial diseases. Pathogenic mutations in
structural subunits (e.g., NDUFA 1, 2, 11; NDUFS 1-4, 6-8; NDUFV
1, 2) and assembly factors (e.g., NDUFAF1-6) have been identified.
Neurodegenerative diseases such as Parkinson's disease,
Alzheimer's disease, and Huntington's disease are also associated
with mitochondrial dysfunction. Further, mtDNA mutations are found
associated with almost all types of cancers. Type 2 diabetes is
also linked with declining mitochondrial function in relevant
tissues such as I2-cells and muscles. Type 2 diabetes represents a
major clinical challenge due to the sharp rise in obesity-induced
disease. Thus, in some embodiments, methods are provided for
treating a mitochondrial disease or a mitochondrial dysfunction.  
  
[0060] Symptoms of mitochondrial diseases usually include slow
growth, loss of muscle coordination, muscle weakness, visual
defect, hearing defects, learning disabilities, mental
retardation, heart disease, liver disease, kidney disease,
gastrointestinal disorders, respiratory disorders, neurological
problems, and dementia.  
  
[0061] The copper (I) complexes of the present invention may be
used to treat mitochondrial diseases such as Myoclonic Epilepsy
with Ragged Red Fibers (MERRF); Mitochondrial Myopathy,
Encephalopathy, Lactacidosis, and Stroke (MELAS); Diabetes
mellitus and deafness (DAD); Maternally Inherited Diabetes and
Deafness (MIDD), Leber's Hereditary Optic Neuropathy (LHON);
chronic progressive external ophthalmoplegia (CPEO); Leigh
Disease; Kearns-Sayre Syndrome (KSS); Friedreich's Ataxia (FRDA);
Co-Enzyme Q10 (Co-Q10) Deficiency; Neuropathy, ataxia, retinitis
pigmentosa, and ptosis (NARP); Myoneurogenic gastrointestinal
encephalopathy (MNGIE); Complex I Deficiency; Complex II
Deficiency; Complex III Deficiency; Complex IV Deficiency; Complex
V Deficiency; and other myopathies that effect mitochondrial
function.  
  
[0062] The copper (I) complexes of the present invention may also
be used to treat a neuromuscular disease. The term aneuromuscular
diseasea refers to disorders that adversely affect muscle function
and/or the control thereof by the central nervous system (CNS). In
general, neuromuscular diseases encompass a wide range of physical
ailments characterized by impaired muscle function. The following
(non-limiting) list of conditions is generally recognized as
neuromuscular diseases or conditions: multiple sclerosis, muscular
dystrophy, rheumatoid arthritis, fibromyalgia, myopathy,
inflammatory bowel disease (IBD), incontinence, inflexibility,
impaired fine motor skills, and amyotrophic lateral sclerosis
(aALSa or Lou Gehrig's disease).  
  
[0063] A stroke, formerly known as a cerebrovascular accident
(CVA), often results in severe neurological impairment.
Post-stroke, many individuals suffer one or more neurological
impairments including, but not limited to: loss of fine motor
control, paralysis, speech impairment/loss (aphasia and/or
dysarthria), altered smell, taste, hearing, or vision, ptosis,
ocular and facial muscle weakness, diminished reflexes, loss of
balance, altered heart rate, apraxia, loss of memory, and/or
confusion.  
  
[0064] Three of the most prominent diseases associated with
impaired neurological function are muscular dystrophy (MD),
multiple sclerosis (MS), and rheumatoid arthritis (RA).  
  
[0065] The term Muscular Dystrophy (MD) actually refers to a group
of diseases characterized by muscle weakness and/or impaired
muscle function. The specific diseases include, but are not
limited to Becker, Duchenne, and Emery-Dreifuss. Over 100
diseases, however, display symptoms similar to MD. All are
characterized by reduced muscle function and muscle weakness.  
  
[0066] Multiple Sclerosis (MS) is an autoimmune disease diagnosed
in 350,000-500,000 people in the United States. The disease is
characterized by multiple areas of inflammation and scarring of
the myelin in the brain and spinal cord. Patients inflicted with
the disease exhibit varying degrees of neurological impairment
depending on the location and extent of the myelin scarring.
Typical MS symptoms include fatigue, weakness, spasticity, balance
problems, bladder and bowel problems, numbness, loss of vision,
tremors, and depression. Available treatments of MS generally only
alleviate symptoms or delay the progression of the disability  
  
[0067] Rheumatoid Arthritis (RA) is another troublesome disorder
associated with inflammation. It is signified by chronic
inflammation in the membrane lining (the synovium) of the joints
and/or other internal organs. These inflammatory cells can also
damage bone and cartilage. For example, a joint inflicted with RA
may lose its shape and alignment, which can result in the loss of
range of motion. RA is characterized by pain, stiffness, warmth,
redness and swelling in the joint, and other systemic symptoms
like fever, fatigue, and anemia. RA currently affects roughly 1%
of the entire U.S. population (approximately 2.2 million people).
The pathology of RA is not fully understood, although it has been
hypothesized to result from a cascade of aberrant immunological
reactions.  
  
[0068] The compositions of the present invention are particularly
effective in treating Lyme disease and Lyme disease co-infections.
Lyme disease is a bacterial infection (Borrelia burgdorferi)
spread by ticks. The number of reported cases of Lyme disease, and
the number of geographical areas in which it is found, has been
increasing. In addition to causing arthritis, Lyme disease can
also cause heart, brain, and nerve problems. Early symptoms
include skin-rash, flu-like symptoms (e.g. chills, fever, swollen
lymph nodes, headaches, fatigue, muscle aches/pains, and joint
pain). More advanced symptoms include nerve problems and
arthritis.  
  
[0069] Lyme disease is often associated with muscle degeneration
and/or muscle weakness. In one aspect of the present invention,
treatment of Lyme disease in a subject with a copper (I) complex
results in improved muscle health and/or muscle tone. In some
embodiments, the Lyme disease is chronic Lyme disease that
persists in spite of treatment with standard antibiotic
treatments.  
  
[0070] Often, ticks can become infected with multiple
disease-causing microbes, resulting in co-infection. This may be a
potential problem for humans, due to Borrelia burgdorferi, and
other harmful pathogens carried and transmitted by some ticks.
Possible co-infections with viruses such as Lyme borreliosis,
anaplasmosis, babesiosis, or encephalitis may occur. It is not
known how co-infection may affect disease transmission and
progression, but may help in diagnosing and treating Lyme and
other such diseases.  
  
[0071] In one embodiment, the present invention is directed to a
method of treating a tickborne disease with a copper (I) complex.
Tickborne diseases include Babesiosis, Ehrlichiosis and
Anaplasmosis, Lyme Disease, Relapsing Fever, Rocky Mountain
Spotted Fever, and Tularemia.  
  
[0072] Tickborne diseases can be found throughout the United
States. For example, Lyme disease, first discovered in Connecticut
in the early 1970s, has since spread to every state except Hawaii.
Rocky Mountain spotted fever, a bacterial disease transmitted by
the dog tick, was first identified in 1896.  
  
[0073] One of the newest tickborne diseases to be identified in
the United States is called Southern tick-associated rash illness
(STARI). This disease has a bull's-eye rash similar to that found
in Lyme disease, which is caused by bacteria transmitted by the
deer tick. Although researchers know that the lone star tick
transmits the infectious agent that causes STARI, they do not yet
know what microbe causes it.  
  
[0074] Ticks transmit ehrlichiosis and anaplasmosis, both
bacterial diseases. Babesiosis is caused by parasites carried by
deer ticks. These diseases are found in several states.  
  
[0075] Tularemia, a less common tickborne bacterial disease, can
be transmitted by ticks as well as other vectors (carriers) such
as the deerfly. Public health experts are concerned that the
bacterium that causes tularemia (Francisella tularensis) could be
used as a weapon of bioterrorism.  
  
[0076] Transmission of tickborne diseases is not limited to ticks.
In addition, tickborne diseases may be spread via other vectors
(e.g., mosquitoes, flies, or other insects), via contaminated body
fluids (e.g., blood transfusions), via sexual transmission or any
other number of ways.  
  
[0077] The copper (I) complexes may be used to treat
gastroparesis. Gastroparesis is a condition characterizes by the
inability of the stomach to empty its contents, when there is no
blockage (obstruction). The cause of gastroparesis is not known.
There is some evidence that it may be caused by a disruption of
nerve signals to the stomach. The condition is a complication of
diabetes and of some surgeries. Risk factors associated with
gastroparesis may include diabetes, gastrectomy (surgery to remove
part of the stomach), systemic sclerosis, use of medication that
blocks certain nerve signals (anticholinergic medication).
Symptoms may include abdominal distention, hypoglycemia (in people
with diabetes), nausea, premature abdominal fullness after meals,
weight loss, and vomiting. If gastroparesis is caused by a
condition that is reversible (e.g. pancreatitis), when the
condition is resolved, the symptoms will subside. For some
diabetics, better control of their blood sugar can also improve
the symptoms. If there is no reversible cause, gastroparesis
rarely resolves itself and the symptoms often grow more sever with
time. When accompanied by motility disorders of the muscles of the
small intestine, gastroparesis is particularly difficult to treat.  
  
[0078] The invention may be used to treat an animal with a disease
or physical ailment or disorder including, but not limited to, one
or more of the following: fibromyalgia, multiple sclerosis,
muscular dystrophy, rheumatoid arthritis, Alzheimer's, dementia,
ALS, depression, pain, fatigue, sleeplessness, inflexibility,
myopathy, Lyme disease, Lyme disease co-infection, gastroparesis
(GP), chronic inflammation, incontinence, impaired fine motor
skills, high cholesterol, low sperm count, obesity, alopecia,
burns, stretch marks, scars, ADD, ADHD, and/or erectile
dysfunction, wherein it is preferable that the animal is a mammal
and more preferable that the mammal is a human.  
  
[0079] In an alternate embodiment, the present invention is
further directed to pharmaceutical and/or dietary supplement
compositions for treating post-stroke symptoms, including, but not
limited to: loss of fine motor control, paralysis, speech
impairment/loss (aphasia and/or dysarthria), altered smell, taste,
hearing, or vision, ptosis, ocular and facial muscle weakness,
diminished reflexes, loss of balance, altered heart rate, apraxia,
loss of memory, and/or confusion.  
  
[0080] Advantageously, the present invention is further directed
to pharmaceutical and/or dietary supplement compositions for
promoting one or more desired health benefits. In a preferred
embodiment, the compositions of the present invention promote hair
growth, skin healing, scar removal, nerve growth, muscle growth,
enhanced athletic performance, reduced post-traumatic healing
time, post-surgery healing, and/or enhanced libido.  
  
[0081] In one embodiment, the subject is first diagnosed with one
of the diseases listed above before treatment.  
  
**Modes of Administration**  
[0082] Frequency of dosage may vary depending on the purity of the
compound and the particular disease or physical ailment treated.
However, for treatment of most diseases and physical ailments, a
dosage regimen of (4) 2.5 mg capsules (for a total of 10 mg/day)
containing copper (I) complexes of the present invention is
preferred. As will be understood by one skilled in the art,
however, the optimal dosage level for a particular subject will
vary depending on a plurality of factors including the potency and
activity of the pharmacologically active ingredient, as well as
the age, body weight, general health, sex, diet, time of
administration, route of administration and rate of excretion,
drug combination (if any) and the severity of the particular
disease or physical ailment undergoing therapy. Subject to the
above factors, a generally effective amount of the copper (I)
complexes of the present invention is between 1 mg and 20 mg per
day. More preferably, the effective amount of is between 5 mg and
10 mg per day. Advantageously, the effective amount of is between
7.5 mg to 10 mg per day. Most preferably (subject to the factors
listed above), the effective amount is about 10 mg/per day.  
  
[0083] Copper (I) complexes of the present invention may also
comprise a component of an overall pharmaceutical treatment regime
for reducing and/or treating a disease or physical ailment or
other disorder including, but not limited to: fibromyalgia,
multiple sclerosis, muscular dystrophy, rheumatoid arthritis,
Alzheimer's, dementia, ALS, depression, pain, fatigue,
sleeplessness, inflexibility, myopathy, incontinence, impaired
fine motor skills, high cholesterol, low sperm count, obesity,
alopecia, burns, stretch marks, scars, ADD, ADHD, and/or erectile
dysfunction, the treatment regime comprising: administering to a
subject at the least the following pharmacologically active
ingredient(s) within a 24-hour period: copper (I) complexes of the
present invention, and optionally a pharmaceutically acceptable
carrier, wherein the pharmacologically active ingredient(s) is in
an amount sufficient to reduce the symptoms of the ailment.  
  
[0084] Optionally, the pharmaceutical treatment regime including
copper (I) complexes of the present invention may include (or be
combined with) additional pharmacologically active ingredients or
other complementary treatments in order to provide synergistic
therapeutic effects. For example, copper (I) complexes of the
present invention may be administered in combination with
additional pharmacologically active agents including, but not
limited to, non-steroidal anti-inflammatory drugs (NSAIDs),
corticosteroids, disease modifying anti-rheumatic drugs (DMARDs),
biologic DMARDs, and/or cyclooxygenase-2 (COX-2) inhibitors. In a
preferred embodiment, copper (I) complexes of the present
invention is administered in combination with ozone therapy.  
  
[0085] The pharmaceutical and/or dietary supplement compositions
of the present invention may take a variety of forms specially
adapted to the chosen route of administration. The compositions
may be administered orally, topically, parenterally, by inhalation
or spray, or by any other conventional means. Preferably, the
compositions are prepared and administered in dosage unit
formulations containing conventional non-toxic pharmaceutically
acceptable carriers, adjuvants and vehicles. In one preferred
embodiment, the composition is administered sublingually. It is
further understood that the preferred method of administration may
be a combination of methods. Oral administration in the form of a
capsule, pill, elixir, syrup, lozenge, troche, or the like is
particularly preferred. The pharmaceutical compositions of the
present invention are preferably in a form suitable for oral use,
for example, as tablets, troches, lozenges, aqueous or oily
suspensions, dispersible powders or granules, emulsion, hard or
softgel capsules, or syrups or elixirs.  
  
[0086] Compositions intended for oral use may be prepared
according to any method known in the art for manufacture of
pharmaceutical compositions, and such compositions may contain one
or more agents selected from the group consisting of sweetening
agents, flavoring agents, coloring agents and preserving agents in
order to provide pharmaceutically elegant and palatable
preparations. Tablets may contain the active ingredient in
admixture with non-toxic pharmaceutically acceptable excipients
suitable for the manufacture of tablets. Such excipients may
include, for example, inert diluents, such as calcium carbonate,
sodium carbonate, lactose, calcium phosphate or sodium phosphate;
granulating and disintegrating agents, for example, corn starch,
or alginic acid; binding agents, for example starch, gelatin or
acacia; and lubricating agents, for example magnesium stearate,
stearic acid or talc. The tablets may be uncoated or they may be
coated by techniques to delay disintegration and absorption in the
gastrointestinal tract and thereby provide a sustained action over
a longer period. For example, a time delay material such as
glyceryl monostearate or glyceryl distearate may be utilized.  
  
[0087] Formulations for oral use may also be presented as hard
gelatin capsules wherein the active ingredient is mixed with an
inert solid diluent, for example, calcium carbonate, calcium
phosphate or kaolin, or as soft gelatin capsules wherein the
active ingredient is mixed with water or an oil medium, for
example peanut oil, liquid paraffin or olive oil.  
  
[0088] Aqueous suspensions contain the active materials in
admixture with excipients suitable for the manufacture of aqueous
suspensions. Such excipients are suspending agents, for example
sodium carboxymethylcellulose, methylcellulose,
hydroxypropylmethylcellulose, sodium alginate,
polyvinylpyrrolidone, gum tragacanth and gum acacia; and
dispersing or wetting agents, which may be a naturally-occurring
phosphatide, for example, lecithin, or condensation products of
ethylene oxide with long chain aliphatic alcoholsafor example,
heptadecaethyleneoxycetanol, or condensation products of ethylene
oxide with partial esters derived from fatty acids and hexitol
anhydrides, for example polyethylene sorbitan monooleate. The
aqueous suspensions may also contain one or more preservatives,
for example ethyl, or n-propyl-p-hydroxybenzoate, one or more
coloring agents, one or more flavoring agents, and one or more
sweetening agents, such as sucrose or saccharin.  
  
[0089] Oily suspensions may be formulated by suspending the active
ingredients in a vegetable oil, for example arachis oil, olive
oil, sesame oil or coconut oil, or in a mineral oil such as liquid
paraffin. The oily suspensions may contain a thickening agent, for
example beeswax, hard paraffin or cetyl alcohol. Sweetening agents
such as those set forth above, and flavoring agents may be added
to provide palatable oral preparations. These compositions may be
preserved by the addition of an anti-oxidant such as ascorbic acid
and/or copper ascorbate.  
  
[0090] Dispersible powders and granules suitable for preparation
of an aqueous suspension by the addition of water provide the
active ingredient (i.e., copper (I) complex) in admixture with a
dispersing or wetting agent, suspending agent and one or more
preservatives. Suitable dispersing or wetting agents and
suspending agents are exemplified by those already mentioned
above. Additional excipients, for example sweetening, flavoring
and coloring agents, may also be present.  
  
[0091] Pharmaceutical compositions of the invention may also be in
the form of oil-in-water emulsions. The oily phase may be a
vegetable oil, for example olive oil or arachis oil, or a mineral
oil, for example liquid paraffin or mixtures of these. Suitable
emulsifying agents may be naturally occurring gums, for example
gum acacia or gum tragacanth; naturally-occurring phosphatide, for
example soy bean, lecithin, and esters or partial esters derived
from fatty acids and hexitol; anhydrides, for example sorbitan
monooleate; and condensation products of the said partial esters
with ethylene oxide, for example polyoxyethylene sorbitan
monooleate. The emulsions may also contain sweetening and
flavoring agents.  
  
[0092] Syrups and elixirs may be formulated with sweetening
agents, for example glycerol, propylene glycol, sorbitol or
sucrose. Such formulations may also contain a demulcent, a
preservative, and flavoring or coloring agents. The pharmaceutical
compositions may be in the form of a sterile injectable aqueous or
oleaginous suspension. This suspension may be formulated according
to the known art using those suitable dispersing or wetting agents
and suspending agents, which have been mentioned above. The
sterile injectable preparation may also be a sterile injectable
solution or suspension in a non-toxic parenterally acceptable
diluent or solvent, for example as a solution in 1,3-butanediol.
Among the acceptable vehicles and solvents that may be employed
are water, Ringer's solution and isotonic sodium chloride
solution. In addition, sterile, fixed oils are conventionally
employed as a solvent or suspending medium. For this purpose, any
bland fixed oil may be employed including synthetic mono- and
diglycerides. In addition, fatty acids such as oleic acid find use
in the preparation of injectables.  
  
[0093] Alternatively, the compositions can be administered
parenterally in a sterile medium. The copper (I) complexes of the
present invention, depending on the vehicle and concentration
used, can either be suspended or dissolved in the vehicle.
Advantageously, adjuvants such as local anesthetics, preservatives
and buffering agents can be dissolved in the vehicle.  
  
[0094] For administration to non-human animals, the composition
containing copper (I) complexes of the present invention may be
added to the animal's feed or drinking water. Optionally, one
skilled in the art will recognize that animal feed and drinking
products may be formulated such that the animal takes in an
effective amount of copper (I) complexes of the present invention
via their diet. For example, copper (I) complexes of the present
invention may constitute a component of a premix formulated for
addition to the feed or drinking water of an animal. Compositions
containing copper (I) complexes of the present invention may also
be formulated as food or drink supplements for humans.  
  
[0095] Preferred embodiments of compositions containing copper (I)
complexes of the present invention will have desirable
pharmacological properties that include, but are not limited to,
oral bioavailability, low toxicity, and desirable in vitro and in
vivo half-lives. The half-life of copper (I) complexes of the
present invention is inversely proportional to the frequency of
dosage of the compounds.  
  
**Synthesis of the Copper (I) Complexes**  
[0096] In one embodiment, the present invention provides a method
of synthesizing a copper (I) glycinate complex. The method
comprises: a) charging a glycinate salt under a stream of inert
gas in an alcohol or water; b) heating the glycinate salt in the
alcohol or water at between 40A deg C. to 45A deg C.; c) adding a copper
(I) salt to the alcohol and allowing to reflux for at least 12
hours; and d) evaporating the alcohol or water and washing the
copper (I) glycinate complex with alcohol and/or water to remove
impurities. In a preferred embodiment, the inert gas is nitrogen.
In some implementations, the glycinate salt is charged under a
stream of inert gas with an ascorbate salt in an alcohol. In one
aspect, the glycinate salt in alcohol is heated for 30 minutes. In
a preferred embodiment, the mixture of copper (I) salt and
glycinate salt in water is refluxed for between 12 to 16 hours. In
some implementations, the mixture of the glycinate salt and copper
(I) salt in water is cooled to about 37A deg C., in a preferred
embodiment, the mixture is further cooled by stirring. In a
preferred implementation, evaporating the alcohol or water and
washing the copper (I) glycinate complex with alcohol and/or water
takes place under nitrogen-purge. For example, the water is dried
by flushing a pressure filter with nitrogen. Once the collected
products on the filter is semi-dry, the drying process continues
in a drying plate, under vacuum conditions, at a temperature of
41A deg C. The isolated crystals of copper (I) glycinate complex
prepared in the absence of the ascorbate salt have a lavender
purple color, whereas isolated crystals of copper (II) glycinate
complex have a blue color.  
  
[0097] In an alternate embodiment, the present invention provides
a method of synthesizing a copper (I) pyruvate complex. The method
comprises: a) charging a pyruvate salt under a stream of inert gas
in an alcohol; b) heating the pyruvate salt in the alcohol at
about 45A deg C.; c) adding a copper (I) salt to the alcohol and
allowing to reflux for at least 12 hours; and d) evaporating the
alcohol and washing the copper (I) pyruvate complex with water to
remove impurities. In some implementations, the pyruvate salt is
charged under a stream of inert gas with an ascorbate salt in an
alcohol. In one aspect, the pyruvate salt in alcohol is heated for
30 minutes. In a preferred embodiment, the mixture of copper (I)
salt and pyruvate salt in water is refluxed for between 12 to 16
hours. The isolated crystals of copper (I) pyruvate complex
prepared in the absence of the ascorbate salt have an
orange-yellow color.  
  
[0098] In another embodiment, the present invention provides a
method of synthesizing a copper (I) succinate complex. The method
comprises: a) charging a succinate salt under a stream of inert
gas in an alcohol; b) heating the succinate salt and the ascorbate
salt in the alcohol at about 45A deg C.; c) adding a copper (I) salt
to the alcohol and allowing to reflux for at least 12 hours; and
d) evaporating the alcohol and washing the copper (I) succinate
complex with water to remove impurities. In some implementations,
the pyruvate salt is charged under a stream of inert gas with an
ascorbate salt in an alcohol. In one aspect, the succinate salt in
alcohol is heated for 30 minutes. In a preferred embodiment, the
mixture of copper (I) salt and succinate salt in water is refluxed
for between 12 to 16 hours. The isolated crystals of copper (I)
succinate complex prepared in the absence of the ascorbate salt
have a pink color.  
  
[0099] In preferred embodiments of the methods of synthesizing a
copper (I) glycinate complex, a copper (I) pyruvate complex, or a
copper (I) succinate complex, the copper (I) salt is copper (I)
chloride. The molar ratios of glycinate salt, pyruvate salt, or
succinate salt to the copper (I) salt may be about 3:1, about
3:1.1, about 3:1.2, about 3:1.3, about 3:1.4, about 3:1.5, about
3:1.6, about 3:1.7, or about 3:1.8. The ascorbate salt used may be
sodium ascorbate, and the alcohol may be ethanol. The molar ratios
of glycinate salt/pyruvate salt/succinate salt to ascorbate salt
to copper (I) salt may be about 3:1:1, about 3:1.1:1.1, about
3:1.2:1.2, about 3:1.3:1.3, about 3:1.4:1.4, about 3:1.5:1.5,
about 3:1.6:1.6, about 3:1.7:1.7, or about 3:1.8:1.8. In one
embodiment, the alcohol is 90% ethanol.  
  
[0100] The methods of synthesizing copper (I) complexes may
further comprise trituration with organic solvents and/or
recrystallization to further purify the copper (I) complexes.  
  
[0101] It is to be understood that the foregoing describes
preferred embodiments of the present invention and that
modifications may be made thereto without departing from the scope
or spirit of the present invention as set forth in the claims.
Such scope is limited only by the claims below as read in
connection with the above specification. Many additional
advantages of applicant's invention will be apparent to those
skilled in the art from the descriptions, drawings, and the claims
set forth herein.  
  
**EXAMPLES**  
**Example 1a. Preparation of a Copper (I) Glycinate Complex**  
[0102] Those skilled in the art will recognize various synthetic
methodologies that may be employed to prepare non-toxic
pharmaceutically acceptable compositions of copper (I) glycinate.
One such (representative) example is set forth below.  
  
**[0103] A 100 mL, 3-necked flask was charged with 90% ethanol
(EtOH), sodium glycinate and sodium ascorbate under a stream of
N2 while charging. The mixture was heated to 45A deg C. for 30
minutes. Cuprous chloride (aka copper (I) chloride, CuCl or
Cu2Cl2) was then added to the mixture and placed under reflux
overnight with N2. The amounts and volumes of each component in
the mixture are shown in Table 1. The molar ratio of sodium
glycinate:sodium L-ascorbate:cuprous chloride was 3:1:1.****TABLE 1****Reaction mixture for production of copper (I) glycinate****Mass  Volume  Molecular

amount of red powder ( I100 mg), which was washed with water.
The mother liquor was concentrated by evaporation of the ethanol
and contained most of the mass as a brown powder.**  
[0105] Proton NMR was performed to identify the copper (I)
glycinate product. Proton NMR (dissolved in D2O) of the red powder
( I100 mg) indicated no presence of starting material or product.  
  
[0106] Proton NMR (dissolved in D2O) of the concentrated mother
liquor indicated a single peak at 3.677 ppm and other small peaks
between 3.7-4.7 ppm (see FIG. 1). The D2O solvent peak is at 4.8
ppm.  
  
[0107] Proton NMR (dissolved in D2O) of sodium glycinate indicated
a single peak at 3.157 ppm, which corresponds to the methylene
(CH2) (see FIG. 2). Proton NMR (dissolved in D2O) of sodium
ascorbate indicated the following peaks: 3.70-3.73 (CH2), 3.99
(CHOH), and 4.49 (CH) ppm that correspond to the expected sodium
L-ascorbate peaks (see FIG. 3).  
  
[0108] In the proton NMR spectrum of the mother liquor there is no
presence of sodium glycinate (3.157 ppm) (see FIG. 1). There is a
singlet peak at 3.67 ppm believed to correspond to the desired Cu
(I) chelated methylene (CH2) product, copper (I) glycinate.

**[0110] The preparation process requires assembly of a
nitrogen-purged 500 ml reaction flask equipped with a mechanical
stirrer, temperature probe/controller, reflux condenser, solid
addition funnel and heating mantle and nitrogen purge. Under
nitrogen purge, the reaction flask is charged with glycine (6.7
g or 0.0893 mol) and deionized water (70 ml). The resulting
mixture is stirred to complete dissolution. The dissolved
mixture is heated to 40-45A deg C. while remaining under nitrogen.
The reaction flask is then charge with ethanol (350 ml) under
nitrogen and then heated back to 40-45A deg C. Via solid addition
funnel, charge the cuprous chloride slowly while maintaining a
temperature of 40-5A deg C. during the addition. Turn off the heat
and allow the mixture to exothermal (about 5-10A deg C. exothermal
is typical). The mixture is cooled to about 37A deg C. and stirred
for approximately one hour. Afterwards, the reaction is removed
from heat and sparged with nitrogen for approximately one hour.
The final product is filtered using a pressure filter under
nitrogen purge. The collected product was rinsed with ethanol
(200 ml) two times with 15 minutes between each rinse. The
collected product on the filter is then flushed with nitrogen
for at least 45 minutes until semi-dry. The collected product on
the filter is transferred to a drying dish and dried under
vacuum at 41A deg C. The drying dish is placed at an angle of 30A deg to
45A deg to facilitate drying and formation of clean crystals. Yield:
I95% of copper (I) glycinate, a lavender purple microcrystalline
solid.**  
  
Example 2. SEM Analysis of Copper (I) Glycinate Complex  
  
[0111] The copper (I) glycinate complex synthesized in Example 1
was analyzed with an SEM, and various images of the copper (I)
glycinate complex were captured (see FIG. 4 for a representative
image). An Energy Dispersive Spectroscopy analysis on the SEM
(EDS-SEM) was run with the energy-dispersive spectrometer set at
an acceleration voltage of 15.0 kV. The EDS-SEM analysis revealed
the presence of carbon I, oxygen (O), and copper (Cu) in the
copper (I) glycinate complex. Sodium (Na), aluminum (Al), and
chlorine (Cl) were also identified as impurities present in the
copper (I) glycinate complex. See FIGS. 5-7.  
  
**Example 3. Preparation of a Copper (I) Pyruvate Complex**  
[0112] Those skilled in the art will recognize various synthetic
methodologies that may be employed to prepare non-toxic
pharmaceutically acceptable compositions of copper (I) pyruvate.
One such (representative) example is set forth below.  
  
**[0113] A 100 mL, 3-necked flask was charged with 90% ethanol
(EtOH), sodium pyruvate and sodium ascorbate under a stream of
N2 while charging. The mixture was heated to 45A deg C. for 30
minutes. Cuprous chloride was then added to the mixture and
placed under reflux overnight with N2. The molar ratio of sodium
pyruvate:sodium L-ascorbate:cuprous chloride was 3:1:1. The
resulting product was concentrated by evaporation of the ethanol
and washed with water to remove residual sodium chloride.**  
Example 4. SEM Analysis of Copper (I) Pyruvate Complex  
  
[0114] The copper (I) pyruvate complex synthesized in Example 3
was analyzed with an SEM, and various images of the copper (I)
pyruvate complex were captured (see FIG. 8 for a representative
image). An EDS-SEM analysis was run with the energy-dispersive
spectrometer set at an acceleration voltage of 20.0 kV. The
EDS-SEM analysis revealed the presence of carbon (C), oxygen (O),
and copper (Cu) in the copper (I) pyruvate complex. Sodium (Na),
chlorine (CO, and calcium (Ca) were also identified as impurities
present in the copper (I) pyruvate complex. See FIGS. 9-11.  
  
**Example 5. Preparation of a Copper (I) Succinate Complex**  
[0115] Those skilled in the art will recognize various synthetic
methodologies that may be employed to prepare non-toxic
pharmaceutically acceptable compositions of copper (I) succinate.
One such (representative) example is set forth below.  
  
**[0116] A 100 mL, 3-necked flask was charged with 90% ethanol
(EtOH), sodium succinate and sodium ascorbate under a stream of
N2 while charging. The mixture was heated to 45A deg C. for 30
minutes. Cuprous chloride was then added and the mixture placed
under reflux overnight with N2. The molar ratio of sodium
succinate:sodium L-ascorbate:cuprous chloride was 3:1:1. The
resulting product was concentrated by evaporation of the ethanol
and washed with water to remove residual sodium chloride.**  
[0117] Because succinic acid possesses two acidic groups, there
are at least two different species of salt possible. The first is
the hemi form, in which only one of the carboxylic acids is in the
copper salt form, while the other is the full salt form in which
there are two coppers to one succinate, one at each carboxylate.
Therefore, the product of this synthesis reaction may contain a
mixture of the hemi salt and the full salt as shown below.  
  
Example 6. SEM Analysis of Copper (I) Succinate Complex  
  
[0118] The copper (I) succinate complex synthesized in Example 5
was analyzed with an SEM, and various images of the copper (I)
pyruvate complex were captured (see FIG. 12 for a representative
image). An EDS-SEM analysis was run with the energy-dispersive
spectrometer set at an acceleration voltage of 20.0 kV. The
EDS-SEM analysis revealed the presence of carbon (C), oxygen (O),
and copper (Cu) in the copper (I) succinate complex. Sodium (Na)
and chlorine (Cl) were also identified as impurities present in
the copper (I) pyruvate complex. See FIGS. 13-15.  
  
Example 7. In Vitro Effects of Copper (I) Glycinate Complex  
  
[0119] The copper (I) glycinate complex synthesized in Example 1b
was used in a mitochondrial stress test using the XF Cell Mito
Stress Test kit (Agilent, Wilmington, Del.). The cells studies
were lymphoblasts from normal subjects (C), lymphoblasts from
autistic donors without mitochondrial dysfunction (N), and
lymphoblasts from autistic donors with mitochondrial dysfunction
(A). ATP-linked respiration, proton leak, maximal respiratory
capacity, and reserve capacity were determined as measured by the
cells' oxygen consumption rate. FIG. 16 depicts the time points
during the course of mitochondrial stress tests that are relevant
for determining ATP-linked respiration, proton leak, maximal
respiratory capacity, and reserve capacity. FIG. 17 depicts the
results of the stress test with that compares the administration
of 100 I1/4M or 500 I1/4M of the copper (I) glycinate to the respiration
of these cells without administration of the copper (I) complex.
Panel B of FIG. 17 shows that 500 I1/4M of the copper (I) glycinate
significantly reduced proton leak lymphoblasts with mitochondrial
dysfunction. Mitochondrial dynfunction in cells was determined
using the methods of the Frye lab, which was described in Rose et
al., aOxidative stress induces mitochondrial dysfunction in a
subset of autistic lymphoblastoid cell lines,a Transl Psychiatry,
2014 4:e377.

Medical Uses of Copper in Antiquity  
Copper Applications in Health
& Environment

June 2000  
  
The first recorded medical use of copper is found in the Smith
Papyrus, one of the oldest books known. The Papyrus is an Egyptian
medical text, written between 2600 and 2200 B.C., which records
the use of copper to sterilize chest wounds and to sterilize
drinking water. Other early reports of copper's medicinal uses are
found in the Ebers Papyrus, written around 1500 B.C. The Ebers
Papyrus documents medicine practiced in ancient Egypt and in other
cultures that flourished many centuries earlier. Copper compounds
were recommended for headaches, "trembling of the limbs" (perhaps
referring to epilepsy or St. Vitus' Dance), burn wounds, itching
and certain growths in the neck, some of which were probably
boils. Forms of copper used for the treatment of disease ranged
from metallic copper splinters and shavings to various naturally
occurring copper salts and oxides. A "green pigment" is spoken of
which was probably the mineral, malachite, a form of copper
carbonate. It could also have been chrysocolla, a copper silicate,
or even copper chloride, which forms on copper exposed to
seawater. In the first century A.D., Dioscorides, in his book De
Materia Medica, described a method of making another green pigment
known as verdigris by exposing metallic copper to the vapors of
boiling vinegar. In this process, blue-green copper acetate forms
on the copper surface. Verdigris and blue vitriol (copper sulfate)
were used, among other things, in remedies for eye ailments such
as bloodshot eyes, inflamed or "bleary" eyes, "fat in the eyes"
(trachoma?), and cataracts.  
  
In the Hippocratic Collection (named for, although not entirely
written by, the Greek physician Hippocrates, 460 to 380 B.C.),
copper is recommended for the treatment of leg ulcers associated
with varicose veins. To prevent infection of fresh wounds, the
Greeks sprinkled a dry powder composed of copper oxide and copper
sulfate on the wound. Another antiseptic wound treatment at the
time was a boiled mixture of honey and red copper oxide. The
Greeks had easy access to copper since the metal was readily
available on the island of Kypros (Cyprus) from which the Latin
name for copper, cuprum, is derived.  
  
By the time the Roman physician Aulus Cornelius Celsus began
practicing medicine, during the reign of Tiberius (14 to 37 A.D.),
copper and its derivatives had been firmly established as an
important drug in the medical practitioner's pharmacopoeia. In
Celsus' series, De Medicina, books one through six list many
purposes for which copper was used together with the preparation
and the form of copper most effective for each ailment. For the
treatment of venereal disease, for example, Celsus prescribed a
remedy consisting of pepper, myrrh, saffron, cooked antimony
sulfide, and copper oxide. These were first pounded together in
dry wine and when dry, once again pounded together in raisin wine
and heated until dry. For a non-healing chronic ulcer, treatment
consisted of copper oxide and other ingredients including enough
rose oil to give a soft consistency.  
  
Pliny (23 to 79 A.D.) described a number of remedies involving
copper. Black copper oxide was given with honey to remove
intestinal worms. Diluted and injected as drops into nostrils, it
cleared the head and, when taken with honey or honey water, it
purged the stomach. It was given for "eye roughness," "eye pain
and mistiness," and ulceration of the mouth. It was blown into the
ears to relieve ear problems.  
  
In the New World the Aztecs also used copper for medical purposes.
Don Francisco de Mendoza commissioned two learned Aztec Indian
physicians to record the pharmacological treatments known by the
Aztecs at the time of the Conquest. For the treatment of "Faucium
Calor" (literally, heat of the throat, or, sore throat) they
prescribed gargling with a mixture of ingredients containing
copper.  
  
Copper was also employed in ancient India and Persia to treat lung
diseases. The tenth century book, Liber Fundamentorum
Pharmacologiae describes the use of copper compounds for medicinal
purposes in ancient Persia. Powdered malachite was sprinkled on
boils, copper acetate as well as and copper oxide were used for
diseases of the eye and for the elimination of "yellow bile."
Nomadic Mongolian tribes treated and healed ulcers of venereal
origin with orally administered copper sulfate.  
  
Turning to more modern times, the first observation of copper's
role in the immune system was published in 1867 when it was
reported that, during the cholera epidemics in Paris of 1832, 1849
and 1852, copper workers were immune to the disease. More recently
copper's role in the immune system has been supported by
observations that individuals suffering from Menke's disease (an
inherited disease in which there is defective copper absorption
and metabolism) generally die of immune system-related phenomena
and other infections. Further, animals deficient in copper have
been shown to have increased susceptibility to bacterial pathogens
such as Salmonella and Listeria. Evidence such as this has led
researchers to suggest strongly that copper compounds not only
cure disease but also aid in the prevention of disease.  
  
In 1885, the French physician, Luton, reported on using copper
acetate in his practice to treat arthritic patients. For external
application he made a salve of hog's lard and 30% neutral copper
acetate. For internal treatment, he used pills containing 10 mg.
of copper acetate. In 1895, Kobert published his review of the
pharmacological actions of copper compounds. Copper arsenate had
been used to treat acute and chronic diarrhea as well as dysentery
and cholera. A variety of inorganic copper preparations were found
to be effective in treating chronic adenitis, eczema, impetigo,
scorphulosis, tubercular infections, lupus, syphilis, anemias,
chorea and facial neuralgia. An organic complex of copper
developed by Bayer was shown to have curative powers in the
treatment of tuberculosis. Copper treatment for tuberculosis
continued until the 1940s, and various physicians reported on
their success in using copper preparations in intravenous
injections.  
  
In 1939, the German physician, Werner Hangarter, noticed that
Finnish copper miners were unaffected by arthritis as long as they
worked in the mining industry. This was particularly striking
since rheumatism was a widespread disease in Finland, and workers
in other industries and other towns had more rheumatic diseases
than did the copper miners. This observation led Finnish medical
researchers plus the Germans, Hangarter and LA1/4bke, to begin their
now classic clinical trials using an aqueous mixture of copper
chloride and sodium salicylate. They successfully treated patients
suffering from rheumatic fever, rheumatoid arthritis, neck and
back problems, as well as sciatica.  
  
Until recently, just as in Pliny's time, the medical profession
used copper sulfate as a means to clinically induce vomiting. This
is based on the fact that one of the body's natural physiological
responses to prevent copper intoxication is vomiting. A Manual of
Pharmacology and its Applications to Therapeutics and Toxicology,
published by W. B. Saunders Company in 1957 recommends the use of
0.5 gram of copper sulfate, dissolved in a glass of water, in a
single dose, or three doses of 0.25 gram fifteen minutes apart,
for this purpose.  
  
Since 1934, it has been known that individuals suffering from such
diseases as scarlet fever, diphtheria, tuberculosis, arthritis,
malignant tumors and lymphogranulomas exhibit an elevation of
copper in their blood plasma. Since then, the list of maladies
bringing about such elevation has been extended to fever, wounds,
ulcers, pain, seizures, cancers, carcinogenesis, diabetes,
cerebrovascular and cardiovascular diseases, and irradiation and
tissue stresses, including restricted blood flow. This suggests
that this redistribution of copper in the body has a general role
in responding to physiological, disease, or injury stress. On the
other hand, the elevation of copper in the affected organ has led
some to postulate that it was this excess of copper that caused
the disease. Nonetheless, this elevation of copper in diseased
states is suggested to account for the natural synthesis of
copper-dependent regulatory proteins and enzymes in the body
required for biochemical responses to stress. It may be that these
natural copper complexes expedite the relief of stress and the
repair of tissues. Thus, it appears that in addition to the
anti-bacterial and anti-fungal activity of inorganic copper
compounds as recognized by the ancients, metallo-organic complexes
of copper have medicinal capabilities that are fundamental to the
healing process itself.  
  
Copper is known to be an essential element in human metabolism.
However, copper does not exist in the body in measurable amounts
in ionic form. All measurable amounts of copper in the body exist
in tissues as complexes with the organic compounds of proteins and
enzymes. Therefore, it has been concluded that copper becomes and
remains intimately involved in body processes. Some copper
complexes serve to store copper, others to transport it, and yet
others play important roles in key cellular and metabolic
processes. Studies into the roles that these copper complexes play
and the mechanisms of these roles have further confirmed that
copper enters into the prevention and control of a number of
disease states in the body. As will be discussed below, the key to
the effective use of copper-based pharmaceuticals is not the use
of inorganic compounds of copper, as used by the ancients, but
rather the use of metallo-organic complexes or chelates of copper.
The process of chelating metals allows them to be smuggled in the
transport process across the intestinal wall and thereby enter
into the mainstream of nutrient flow and usage in the body.  
  
The first modern research on the subject of copper medicinal
substances was by Professor John R. J. Sorenson, of the University
of Arkansas for Medical Sciences, College of Pharmacy, who, in
1966, demonstrated that copper complexes have therapeutic efficacy
in the treatment of inflammatory diseases using doses that are
nontoxic. Since then, copper metallo-organic complexes have been
used to successfully treat patients with arthritic and other
chronic degenerative diseases. More than 140 copper complexes of
non-steroidal anti-inflammatory agents (aspirin and ibuprofen, for
example) have been shown to be more active than their parent
compounds. Copper aspirinate has been shown not only to be more
effective in the treatment of rheumatoid arthritis than aspirin
alone, but it has been shown to prevent or even cure the
ulceration of the stomach often associated with aspirin therapy.
Based on these experiences, the work of Professor Sorenson and
other researchers around the world has progressed into the
medicinal benefits of organic complexes of copper in a number of
disease states. This work, thus far mainly based on animal
research, has opened a whole new vista both into the understanding
of copper's many-fold role in the body and in the practicality of
using supplementary copper in the treatment of wound healing and
inflammation-related disease states. Some of these potential
indications are:  
  
Ulcer and Wound-Healing
Activities of Copper Complexes  
  
It has been demonstrated that copper complexes such as copper
aspirinate and copper tryptophanate, markedly increase healing
rate of ulcers and wounds. For example, copper complexes heal
gastric ulcers five days sooner than other reagents. Further, it
has been shown that, whereas non-steroidal anti-inflammatory
drugs, such as ibuprofen and enefenamic acid suppress wound
healing, copper complexes of these drugs promote normal wound
healing while at the same time retaining anti-inflammatory
activity.  
  
Anticonvulsant Activities of
Copper Complexes  
  
The brain contains more copper than any other organ of the body
except the liver, where copper is stored for use elsewhere. This
fact suggests that copper plays a role in brain functions. With
reports of seizures in animals and humans following the protracted
consumption of copper-deficient diets, it was reasoned that copper
has a role to play in the prevention of seizures. It was
subsequently discovered that organic compounds that are not
themselves anti-convulsants exhibit anticonvulsant activity when
complexed with copper. Further, it was found that copper complexes
of all anti-epileptic drugs are more effective and less toxic than
their parent drugs.  
  
Anticancer Activities of Copper
Complexes  
  
As early as 1912, patients in Germany were treated for facial
epithelioma with a mixture of copper chloride and lecithin.
Success of such treatment suggested that copper compounds have
anticancer activity. Work at the University of Liverpool in 1913
demonstrated that subcutaneous and intravenous injections of a
copper salt or colloidal copper softened and degenerated
carcinomas transplanted into mice. In 1930, work in France
indicated that injections of colloidal copper mobilized and
expelled tumor tissue. Recent work with mice in the USA has shown
that, indeed, treatment of solid tumors with non-toxic doses of
various organic complexes of copper markedly decreased tumor
growth and metastasis and thus increased survival rate. These
copper complexes did not kill cancer cells but caused them to
revert to normal cells.  
  
Anticarcinogenic Activity of
Copper Complexes  
  
Based on work in the treatment of cancers using copper complexes,
researchers have found that these same complexes may prevent or
retard the development of cancers in mice under conditions where
cancers are expected to be induced.  
  
Radiation Protection and
Radiation Recovery of Copper Complexes  
  
Ionizing radiation, such as that used in the treatment of cancer,
has been shown to induce massive systemic inflammation. Ideally,
such radiation-induced injury might be prevented or ameliorated by
chemical repair mechanisms in the body. Thus, pharmacological
approaches to the repair of radiation-damaged tissue are needed.
As early as 1984, copper metallo-organic complexes have been shown
to have radiation protection and radiation recovery activities.
They are capable of causing rapid recovery of immunocompetence and
recovery from radiation induced tissue changes. The mechanism of
this activity appears to be tied to the ability of certain copper
complexes to deactivate the superoxide, or "free," radicals
liberated by ionizing radiation. In addition, since radiation has
the capability of breaking the bonds of natural copper enzymes in
the body, supplementing these with non-toxic doses of
pharmaceutical copper complexes restores the lost tissue-repair
capability. Since these complexes may also have anticarcinogenic
activity, it is suggested that there would be merit in using
copper complexes in the treatment of cancer and in particular,
treating patients undergoing ionizing radiation therapy for their
cancer, accidental exposure to radiation, and astronauts
undertaking space travel.  
  
Heart Disease and Copper
Complexes  
  
Numerous studies have drawn attention to the relationship between
copper deficiency and heart disease. First observed in rats in
1936, this effect has now been traced to both a deficiency in
copper and an imbalance in the copper-to-zinc ratio in the body.
Work by Dr. L.M. Klevay at the U.S. Department of Agriculture,
Human Nutrition Research Center in 1973 has led to the postulation
that copper has a direct effect on the control of cholesterol. In
continuing work published in 1975, he theorized that a metabolic
imbalance between zinc and copper - with more emphasis on copper
deficiency than zinc excess - is a major contributing factor to
the etiology of coronary heart disease. Subsequent work by other
investigators has shown that copper complexes also can have a
valuable role in the minimization of damage to the aorta and heart
muscle as oxygenated blood reperfuses into tissues following
myocardial infarction. This action is based on the
anti-inflammatory action of copper complexes. These and other
studies suggest the use of copper dietary supplements as a means
of preventing and controlling such diseases as atherosclerosis (a
form of arteriosclerosis), coronary heart disease, aortic
aneurysms and myocardial infarction. It has been speculated that
the reason that the heart attack rate in France is lower than in
the rest of Europe is because of the French practice of drinking
red wine. Red wine has a higher copper content than white wine
because it is prepared with the skin of the grape intact. The
copper originates in the wine from the copper fungicides used on
the grapes in the field.  
  
Based on an abundance of historical data such as the foregoing,
many researchers anticipate that copper will become an
increasingly important component of tomorrow's medical treatments.

Copper(II) aspirinate is an aspirin chelate of copper(II) cations
(Cu2+). It is used to treat rheumatoid arthritis.  
  
Molecular formula     C36H28Cu2O16  
Molar mass     843.69g/mol

Except where noted otherwise, data are given for materials in
their standard state (at 25 A degC, 100 kPa)  
  
Preparation  
  
Copper aspirinate can be prepared by several methods. In one route
of preparation, an excess of acetylsalicylic acid is dissolved in
aqueous sodium carbonate. Sodium hydroxide is not suitable for
this purpose, because it will hydrolyse acetylsalicylic acid (ASA)
into salicylic acid and sodium acetate.  
  
2 HC9H7O4 + Na2CO3 ? 2 NaC9H7O4 + CO2? + H2O  
  
The resulting solution is then filtered to remove any undissolved
acetylsalicylic acid and is mixed with a solution containing Cu2+
cations (copper(II) sulfate is suitable), precipitating bright
blue crystals of copper aspirinate immediately. The crystals can
then be filtered from solution, washed, and dried. An excess of
acetylsalicylic acid is used in the first step, because it
eliminates the possibility of unreacted carbonate anions
precipitating the copper in this step.  
  
4 NaC9H7O4 + 2 CuSO4 ? C36H28Cu2O16? + 2 Na2SO4  
  
Medicinal Use  
  
Copper aspirinate has been proven effective as a treatment for rheumatoid arthritis.[1] The
studies on animal models suggest that copper aspirinate is very
promising in treating against thrombotic

Copper Aspirinate Synthesis  
by   
Brian Fraser

  
Disclaimer: The following
is a summary of the procedure I used to make copper aspirinate. I
offer it here for informational purposes to show that copper
aspirinate can be made with commonly available materials and
equipment. A similar procedure is typically done by second-year
college chemistry students as a laboratory exercise in a setting
supervised by a professional instructor. I do NOT recommend that
people do this at home. Some aspects of these procedures are
hazardous, and the typical home kitchen simply has too many
distractions and interruptions for a student to carry out these
procedures safely. Your wife ( or mom) will also be furious if you
get copper sulfate stains on her kitchen counter!  
  
Copper Aspirinate synthesis
(kitchen method)  
  
Equipment and Materials required  
  
1. Saturated copper acetate solution. See procedure below.  
  
2. Pure aspirin crystals. See procedure below.  
  
3. Ethanol  (95%; liquor store ethanol like Everclear (190
proof, UPC 088352100036) is what was used here.  
  
4. Vacuum filtration facilities (BA1/4chner funnel, coarse and medium
porosity filter paper, aspirator, filter flask, seals, tubing,
clamps, stand, etc. These common lab tools are not absolutely
necessary, but can speed things up considerably.)  
  
5. Containers for liquid such as Rubbermaid 24 fl. oz. servin'
saver tm (used here as a "beaker").  
  
Procedure  
  
1. Add 1 fl. oz. of saturated copper acetate solution to a beaker.  
  
2. Dissolve 1 tsp (teaspoon) pure aspirin crystals in about 1 fl.
oz. of ethanol (95%) in another beaker  
  
3. Pour the aspirin solution into the copper acetate solution.
Stir occasionally.  
  
4. Dark blue crystals will gradually form on the sides and bottom
of the beaker. The initial layer will form immediately if the
beaker has been freshly cleaned and scoured. The layer will
gradually thicken and become bluer and darker. This process may
take several hours. The endpoint is reached when the liquid has
turned a light blue and no more blue crystals are forming on the
walls of the beaker. (You can verify the endpoint by siphoning the
clear liquid, evaporating it in a separate container, and checking
the residue. The residue should be mostly aspirin crystals.)  
  
This procedure requires no heating. If you heat the liquid to
increase the reaction rate, be aware that aspirin can hydrolyze
into acetic and salicylic acids in a moist or liquid environment.
If that happens, the liquid will turn dark green, and the yield
of  copper aspirinate will be greatly reduced.  
  
5. Cool the mixture in a refrigerator.  
  
6. Scrape the crystals off the sides and bottom of the beaker.
Then vacuum filter the whole mixture. (Save the first filtrate in
a separate container if you do ethanol solvent recycling.)  
  
7. Wash the blue powder on the filter with cold distilled water.  
  
8. Dry the powder and filter paper in an oven at about 120F. Store
the dry powder in a small dark bottle with a label identifying the
contents and the date of creation.  
  
Alternative Procedure  
  
Substitute isopropanol (99%)  for the ethanol in step #2 and
use 1/2 teaspoon, instead of 1 teaspoon, of aspirin crystals and
1/2 fl. oz. isopropanol instead of 1 fl. oz of ethanol. After
several hours of initial crystallization,  add 1/2 fl. oz. of
distilled water and place the beaker in the refrigerator and wait
a few more hours for more crystals. This variation gives about the
same results as the ethanol procedure. Its advantages are that it
uses less excess aspirin and a less expensive alcohol.  
  
Aspirin purification (kitchen
method)  
  
Equipment and Materials required  
  
1. One bottle of 1000 commercial aspirin tablets (preferably the
uncoated kind).  
  
2. A pint or two of isopropyl alcohol (99%). This is usually
available from a hardware store. Sometimes it can be found in a
drugstore (UPC: 341226909730 ) Isopropanol is extremely flammable,
so be very careful not to expose vapors to hidden or unexpected
ignition sources.  
  
3. A couple of gallons of deionized or distilled water.  
  
4. Three, 24 fl. oz.  wide-mouthed polypropylene containers
with covers, such as Rubbermaid servin' saver tm.  
  
5. Oven thermometer (easily read dial type is best)  
  
6. Modified turkey baster (see construction procedure below)  
  
7. One kitchen (with sink, refrigerator, oven, etc)  
  
Procedure:  
  
1. Dump a few hundred aspirin tablets into a wide-mouthed
container.  
  
2. Add distilled water to the container and stir. This will break
up the aspirin tablets and dissolve the hydroxypropyl
methycelluose coating that is usually used to coat aspirin
tablets. Let the mixture settle for an hour or so in the
refrigerator.  
  
3. Siphon most of the water out with a modified turkey baster.  
  
4. Repeat steps #2 and #3 a total of three to five
times.   This will largely get rid of the methycellulose
coating, which tends to clog filters. You might not need to repeat
these steps if you  use uncoated aspirin.  
  
5. Vacuum filter the mixture from #4 and dry the powder in air.
(Caution: aspirin tends to decompose when heated in a moist
environment).  
  
6. Add the powder to a quart container. Add about a half-cup of
isopropyl alcohol (99%). Stir. This will dissolve part, but not
all, of the aspirin. Let the mixture settle.  
  
7. Vacuum filter the above mixture using medium porosity filter
paper. Pour the filtrate into a clear glass container for
inspection. If the filtrate is not clear, re-establish vacuum on
the filter, and filter it again. (Sometimes simply letting the
mixture settle and then siphoning the clear liquid with a turkey
baster is more effective than filtration; the latter, however, may
be faster.)  
  
8. Pour the clear filtrate containing the dissolved aspirin into
the second container, cover it,  and place it in the freezer
(about 5 F or so). After an hour or so the aspirin will
crystallize out of solution. Return the powder on the filter to
its original quart container.  
  
9. After the aspirin crystals have formed,   remove the
container from the freezer. Carefully decant the liquid back into
the first container that contains the impure aspirin powder. Then
scrape out the pure aspirin crystals into a third container.  
  
10.  Cover this first container (impure aspirin powder and
recovered isopropanol) and let it warm to room temperature.
Agitate it occasionally so that more aspirin will again dissolve.  
  
11. Repeat steps 7 through 10 until you have recovered all the
aspirin, and the filter paper has only a thin layer of the
excipients (typically calcium phosphate, starch, talc, etc. These
impurities are added to the tablets to help them break up in
water). Discard the filter paper. Dump the isopropanol down the
drain, and wash it down with some tap water.  
  
12. Using new  filter paper (medium porosity),  filter
any remaining isopropanol from the recovered aspirin crystals
(third container).  Rinse the third container with distilled
water and wipe it dry. Dump the filtered crystals back into the
third container and cover them with cold distilled water.
Re-establish vacuum on the filter and filter the crystals again.
This will rinse off any remaining isopropanol. Discard the liquid.
(Repeat the procedure if you can still smell isopropanol on the
crystals).  
  
13. Finally, gently dry the aspirin crystals. (I dried mine in an
oven at 120 F. If you do this, BE SURE you have rinsed the
crystals well enough so that there are no isopropanol vapors
present. Isopropanol forms explosive vapors with air, and allowing
these to accumulate in a confined space is a recipe for serious
trouble. Also, aspirin tends to decompose when heated, especially
in hot water, so I use only a warm temperature setting. )  
  
Copper acetate synthesis
(kitchen method)  
  
Equipment and Materials required  
  
1. Copper sulfate pentahydrate 99%. This is usually available from
a hardware store in the form of a product used to kill tree roots
in sewers and septic tanks, such as Roebic K-77.  
  
2. Arm and Hammer Baking soda (sodium bicarbonate).  
  
3. A couple of quarts of distilled vinegar (5% acetic acid).  
  
4. A Pyrex casserole dish (22 x 11 x 6 cm or similar)  
  
5. Vacuum filtration facilities.  
  
6. Various clean, quart containers.  
  
Procedure  
  
Preparation of filtered copper
sulfate solution  
  
1. Dissolve 3/4 cupful of copper sulfate crystals in about a quart
of warm distilled water.  
  
2. Vacuum filter the solution through coarse porosity filter
paper. This will filter out suspended solids (metal flecks,
"dirt", etc.). Pour the filtrate off into a clear inspection
container. Vacuum filter the solution again with medium porosity
paper until it is clear blue. Note that the filtrate may still
contain significant impurities (lead, arsenic, cadmium, etc.) at
this point. Remember that this product is normally used in sewers.  
  
3. Save the clear blue solution for later use.  
  
(4. If you want higher purity copper sulfate, you can
re-crystallize it at this point.)  
  
Preparation of sodium carbonate
solution  
  
1. Pour a cup full of sodium bicarbonate into a Pyrex casserole
dish. Add distilled water sufficient to dissolve it.  
  
2. Heat the solution in an oven to about 200F. This will cause the
bicarbonate to decompose into the carbonate with the evolution of
carbon dioxide.  The end result will be a solution of sodium
carbonate.  
  
3. Let the solution cool to room temperature. Carbonates are
somewhat less soluble than bicarbonates; add more distilled water
if necessary to keep the material in solution.  
  
Preparation of copper carbonate  
  
1. In a large container, gradually combine the copper sulfate
solution with the sodium carbonate solution. A blue-green
precipitate will immediately form along with the vigorous release
of carbon dioxide. Let the precipitate settle out.  
  
2. At this point the liquid portion will have either an excess of
sodium carbonate or of copper sulfate. If you add a drop of sodium
carbonate and see some precipitate form, then the bulk mixture
needs more sodium carbonate solution added. Likewise, if you add a
drop of copper sulfate and see a precipitate, then the bulk
mixture needs more copper sulfate solution added. Make these
adjustments as necessary until there is no longer an unambiguous
formation of the blue-green precipitate.  
  
3. Vacuum filter the mixture with a coarse porosity paper filter.
Discard the liquid. Wash with cold distilled water and then
refilter. This will wash out any excess sodium carbonate or copper
sulfate.  
  
Preparation of copper acetate
solution  
  
4. To a quart container, add the still moist copper carbonate
powder from the previous step. Then slowly pour vinegar into the
container. Carbon dioxide will evolve and copper acetate will
form. The solution will gradually become a deep blue color. A
blue-green precipitate may also settle to the bottom of the
container.  
  
5. Let the solution settle out. If there is a substantial amount
of blue-green precipitate at the bottom of the container, add more
vinegar. Try to dissolve most, but not all, of this precipitate.
An excess of vinegar is harder to remove than a little of the
precipitate.  
  
6. Using coarse paper, vacuum filter the resulting copper acetate
solution. Repeat until clear. Discard the paper. Save the blue
filtrate.  
  
7. Slowly evaporate the blue filtrate in a Pyrex casserole dish in
an oven (150F) for several hours. Periodically scrape down the
sides of the dish to prevent a build up of crystals. Continue the
evaporation until some blue-black crystals of copper acetate begin
to form (and do not redissolve). The mixture may also have some
blue-green "pond scum" in it too.  
  
8. Cool and filter the dark blue solution. Store it in a clear
glass container for observation (a one quart vinegar bottle works
fine). This is the saturated copper acetate solution that will be
used to make copper aspirinate.  
  
9. If you want to make copper acetate crystals, continue the
evaporation process until blue-black crystals form. This will
require evaporating most, but not all, of the solution. Impurities
(and excess vinegar) tend to remain in solution instead of
crystallizing out. Hence, it is necessary to discard a small
portion of the original solution. Collect the crystals on the
vacuum filter and discard the leftover liquid. Wash the blue-black
crystals with a little bit of cold distilled water. Then dry and
store them in a labeled container.  
  
Conversion of Aspirin to
Salicylic acid (kitchen method)  
  
1. Put about 4 tsp of pure aspirin crystals (see above) and 1/2
cup distilled water into a small, clean  jar (such as one
used for canning pickles or olives).  
  
2. Place jar on a hot pad in a shallow pan in an oven set to about
225F.   Let the aspirin hydrolyze into acetic and
salicylic acids for an hour or two. (Add a little more water if
all the crystals have not dissolved in the hot liquid.)  
  
3. Cool the liquid in the refrigerator. You should see needle-like
crystals.  
  
4. Vacuum filter and wash the crystals with cold distilled water.
This will remove acetic acid residue.  
  
5. Dump the crystals out of the filter and air dry them. (they
usually come out as a mat of fine needles). Store in a properly
labeled bottle.  
  
Conversion of Salicylic acid to
Phenol  
  
Phenol (carbolic acid) is an important disinfectant and germicide,
as well as an important organic reagent.  
  
According to the Merck Index (10th ed.), salicylic acid sublimes
at 76 C, melts at 159 C,  and will decompose into phenol and
carbon dioxide when rapidly heated at atmospheric pressure.  
  
Copper Salicylate Synthesis
(kitchen method)  
  
1. In a small custard dish, dissolve 1/4 tsp of sodium bicarbonate
(baking soda) in a few of teaspoons of distilled water.  
  
2. Add about 1/2 tsp of the salicylic acid crystals recovered from
the conversion described above. Mixture will fizz a little. Stir
until all the crystals dissolve.  
  
3. Test the pH. Add more salicylic acid or bicarbonate to get pH
of about 6 (slightly acid). This is now a solution of sodium
salicylate.  
  
4. Add copper sulfate solution drop by drop. An ugly green
precipitate  (copper salicylate) will form.

**NanoCopper Preparation**

**Three-step reduction method preparation
process for nanocopper**  
**CN103817345**

  
The invention relates to a three-step reduction method preparation
process for nanocopper. The preparation process comprises the
following steps: 1, preparing copper sulfate solution, potassium
hydroxide solution, ascorbic acid, formaldehyde solution and
potassium borohydride solution; 2, single-step reduction: ascorbic
acid solution is dropwise added into the copper sulfate solution
while stirring is carried out; 3, two-step reduction: the
formaldehyde solution is added; 4, three-step reduction: the
potassium hydroxide solution is added, the pH value of the
solution is adjusted to 9-13, the potassium borohydride solution
is dropwise added and is stirred until sediment is completely
generated, and copper powder is obtained by filtration; 5;
cleaning and drying the copper powder to obtain 300-800 nm
nanocopper. By means of three reduction reagents, and according to
the reducibility difference of the reduction reagents, the
reduction reagents are added into the dissolvable copper sulfate
solution in sequence to prepare the nanocopper, and the nanocopper
is thinner in grain size, smaller in distribution range and more
uniform.  
  
**Technical field**  
The invention relates to the technical field of metal copper
powder preparation, in particular to a three-step reduction
preparation process of nano copper powder.  
  
**Background technique**There are many kinds of preparation methods for copper powder,
and there are high energy ball milling method and vapor phase
deposition method in physical methods. The ball milling method
selects a suitable ball mill and ball milling material, and uses
the rotation or vibration of the ball mill to make the hard ball
strongly impact, crush and grind the material, and break the
copper block into ultrafine particles. The advantages of the ball
milling method are simple. The yield is high, and the disadvantage
is that the obtained copper powder has a wide particle size
distribution, many impurities, and low purity. Vapor deposition is
a method of preparing copper powder by rapidly cooling metal
copper after heating and melting in an inert gas such as argon gas
or helium gas. Electrolytic preparation of copper powder is a
relatively common and industrial method for the production of
copper powder. Generally, in a copper electrolysis cell, the
copper powder deposited on the cathode is scraped off at intervals
of 20 minutes to avoid particle growth. The scraped copper powder
is subjected to ball milling, sieving and the like to obtain the
finally obtained copper powder. Ultrasonic electrolysis is an
improved electrolysis process that uses ultrasonic vibration and
cavitation to generate high pressure or jets to cause deposited
copper particles to detach from the surface of the cathode and to
suspend the particles in the electrolyte. In addition, there are
high temperature, high pressure hydrothermal method, ?-ray
irradiation method, polyol method and microwave polyol method.
Among the numerous preparation methods of copper powder, the
method of preparing copper powder by reducing soluble copper salt
is one of the common methods for preparing copper powder in
laboratory and industry. The commonly used reducing agents include
reducing agents such as glucose, ascorbic acid, hydrogen peroxide,
formaldehyde, sodium hypophosphite, hydrazine hydrate, and
potassium borohydride. In many laboratory experiments, copper
powder is mostly prepared by the application of a reducing
reagent. For example, Liao Wei prepared 40-200 nm copper powder
with formaldehyde as a reducing agent; Zhao Bin prepared hydrazine
hydrate as a reducing reagent. With ~500nm copper powder, the
prepared copper powder has a very wide particle size.

(5) The copper powder obtained by the step (4) was washed three
times with deionized water and absolute ethanol, and then dried in
a drier filled with an inert gas to obtain a nano copper powder of
300 to 800 nm.  
  
10 to 50 ml of ascorbic acid is added per 50 to 150 ml of copper
sulfate solution.
