Professor Knoll was the originator of deprenyl, (or selegiline) and his ground breaking research in the 1960’s established the longevity effects of deprenyl on animals and affirmed deprenyl as the first proven longevity drug. His work with deprenyl and its effects on the neurotransmitter dopamine have broad implications for both Parkinson’s disease and age-related-mental-decline. Professor Knoll was head of the department of pharmacology at Semmelweiss University of Medicine in Hungary- before his retirement in 2013. Dr. Knoll is also an award holder for Excellence in Antiaging Medicine from the Monte Carlo Antiaging Conference.
