In the present study, a number of isomeric 4-naphthyl-, 4-(naphthylalkyl)-, 4-thienyl-, and 4-(thienylalkyl)tetrahydropyridines, conformationally restrained and flexibleanalogs of MPTP, were synthesized and evaluated as potential selective substrates of MAO A and B. In terms of the parameter (turnover number)/Km, the bulky naphthyl analogs were invariably better substrates of MAO A than kynuramine
tunnel of ChAT and interactions with a hydrophobic pocket near the choline binding site have major implications for the molecular recognition of inhibitors. Our findings clarify the inhibition mechanism of AVPs, establish a drug modality that exploits a target‐catalysed reaction between exogenous and endogenous precursors, and provide new directions for the development of ChAT inhibitors with improved potency
