Description: S-17092 is a drug which acts as a selective inhibitor of the enzyme prolyl endopeptidase. This enzyme is involved in the metabolic breakdown of a number of neuropeptide neurotransmitters in the brain, nd so inhibiting the action of the enzyme increases the activity of these neuropeptides. This produces nootropic effects which make S-17092 a promising and novel treatment for neurodegenerative conditions such as Alzheimer's disease and Parkinson's disease.
