The structures of all compounds were confirmed by IR H-1 NMR C-13 NMR mass spectral data and elemental analyses. All the compounds were investigated for their ability to selectively inhibit MAO isoforms by in vitro tests and were found to inhibit recombinant human MAO-B selectively and reversibly in a competitive manner. Among the compounds examined compound 16 was found to be more selective than selegiline a known MAO-B inhibitor in respect to the K (i) values experimentally found. Additionally compounds 9 and 15 showed moderate MAO-B inhibitor activity. The interaction of compounds with MAO isoforms was investigated by molecular docking studies using recently published crystallographic models of MAO-A and MAO-B. The results obtained from the docking studies were found to be in good agreement with the experimental values.eninfo:eu-repo/semantics/openAccessHydrazone5-methyl-2-benzoxazolinoneHuman monoamine oxidase B inhibitorsMolecular dockingArticle8838916120WOS:00031943300000710.1007/s00702-013-0968-22-s2.0-84878699680Q2Q223328949
