S-17092

S-17092 is a drug which acts as a selective inhibitor of the enzyme prolyl endopeptidase.[1] This enzyme is involved in the metabolic breakdown of a number of neuropeptide neurotransmitters in the brain,[2][3] and 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.[4][5]
