SYNTHESIS, STRUCTURAL CHARACTERIZATION AND ENZYME INHIBITION STUDIES ON 5-(2-NITROSTYRYL)-1,3,4-OXADIAZOLE-2-THIOL DERIVATIVES

In the present work, S-substituted derivatives of 5-(2-nitrostyryl)-1,3,4-oxadiazole-2-thiol (4) were synthesized by successive conversions of 3-(2-nitrophenyl) acrylic acid (1) into its respective ester, hydrazide and 1,3,4-oxadiazole. Finally the target compounds were obtained by reaction of 5-(2-...

Sumario:In the present work, S-substituted derivatives of 5-(2-nitrostyryl)-1,3,4-oxadiazole-2-thiol (4) were synthesized by successive conversions of 3-(2-nitrophenyl) acrylic acid (1) into its respective ester, hydrazide and 1,3,4-oxadiazole. Finally the target compounds were obtained by reaction of 5-(2-nitrostyryl)-1,3,4-oxadiazole-2-thiol (4) with a series of various electrophiles, (5a-I), in NN-dimethyl formamide (DMF) in the presence of sodium hydride (NaH). The structural characterization of these newly synthesized compounds was done by IR, ¹H-NMR, HR-MS and EI-MS spectral data. All these compounds were evaluated for their enzyme inhibitory potentials and found to exhibit broad range spectrum against acetylcholinesterase, butyrylcholinestrase and lipoxygenase enzymes.
