Abstract

A small library of 1-(4-nitrophenyl)-3-arylprop-2-en-1-one derivatives was synthesized to identify new human Monoamine Oxidase B selective inhibitors. Their inhibitory activity toward MAO-A and MAO-B isoforms was evaluated to determine their potency and selectivity. All newly synthesized compounds were nanomolar inhibitors of the B isoform with IC50 concentrations ranging from 120 to 2.2 nM. Conversely, their activity toward the A isozyme was only observed at micromolar concentrations. Our results bear out the hypothesis that the 1,3-diarylpropenone scaffold could represent a valuable starting point for designing efficient and selective MAO-B inhibitors.
