Substrate-like novel inhibitors of prolyl specific oligo peptidase for neurodegenerative disorders

Prolyl specific oligopeptidase (POP), is one of the highly expressed enzymes in the brain and is a prime target to treat disorders related to the central nervous system. Here, we describe the structure-based design of the tacrine derivatives, selective, and brain-permeable POP inhibitors. These compounds inactivate POP in-vitro specifically and sustainably at very low concentrations (nano molar). Among this series, compound
