Goal
Extend healthy lifespan and reduce age-related damage by identifying and cataloguing geroprotective compounds.
Problem
Lack of a curated, searchable resource that links chemical compounds to experimentally demonstrated anti-aging effects.
Concept Summary
A publicly accessible database (Geroprotectors.org) aggregates >250 experiments on >200 compounds that extend lifespan in model organisms. Parallel research screened >10,000 plant extracts, identifying six extracts (including willow bark) that dramatically increase yeast chronological lifespan, likely via hormetic stress responses and modulation of mitochondrial function, ROS, and cellular repair pathways.
Principles
- Hormetic stress response
- Mitochondrial respiration enhancement
- Modulation of reactive oxygen species
- Reduction of oxidative damage to proteins, lipids and DNA
- Enhanced cellular stress resistance
Scientific Domains
Materials
- Salicin (white willow bark)
- Cimicifuga racemosa extract
- Valeriana officinalis extract
- Passiflora incarnata extract
- Ginkgo biloba extract
- Apium graveolens extract
- Allantoin
Mechanisms of Action
- Increased mitochondrial membrane potential
- Altered ROS concentrations
- Accelerated lipid droplet degradation
- Activation of cellular repair pathways
Applications
- Anti-aging therapeutics
- Prevention of age-related diseases
- Research tools for gerontology
Claimed Performance
Willow bark extract increased average yeast chronological lifespan by 475 % and maximum lifespan by 369 % - the strongest longevity-extending effect reported to date.
Experimental Evidence
Screening of >10,000 plant-extract trials in yeast; lifespan assays showed >400 % increase for willow bark extract; other five extracts also produced significant lifespan extensions.
Replication Status
Results have not yet been replicated in animal models beyond yeast.
Limitations
- Efficacy demonstrated only in yeast; unknown in mammals or humans
- Mechanistic pathways not fully elucidated
- Potential variability in plant extract composition
