    "concept_summary": "A water-soluble pro-drug (Minnelide) derived from the natural compound triptolide, extracted from the root of Tripterygium wilfordii (Thunder God Vine), was shown to eradicate pancreatic tumors in mice after a 40-day treatment course.",
    "detailed_description": "Researchers at the University of Minnesota Masonic Cancer Center isolated triptolide from the skinned root of Tripterygium wilfordii, synthesized a water-soluble formulation called Minnelide, and administered it intravenously to mice bearing pancreatic tumors. Over a 40-day period the treated mice showed complete disappearance of detectable tumors, and the effect persisted after treatment cessation. The study was published in Science Translational Medicine and funded by the NIH. The same compound has a history of use in traditional Chinese medicine for inflammatory conditions and rheumatoid arthritis.",
