[摘要]：A series of 2-benzy1-3-(2-arylidenehydrazinyl)quinoxalines 3, 4-benzyl-1-aryl-(1,2,4]triazolo[4,3-a]quinoxalines 4 and phenyl(1-aryl-[1,2,4]triazolo[4,3-a]quinoxalin-4-yl)methanones 5 analogues were synthesized and investigated for their monoamine oxidase (MAO) inhibitory property. The inhibition profile was found to be competitive for compounds 3k, 3m, 5f and 5n with MAO-A selectivity Observation of the docked positions of these compounds revealed interactions with many residues previously reported to have an effect on the inhibition of the enzyme. The structural features of the new compounds have been determined from the microanalytical, IR, H-1, C-13 NMR spectral studies and X-ray crystalography. (C) 2010 Elsevier Masson SAS.
