Özet

In this study, we prepared some new oxadiazolyl benzimidazole derivatives and investigated their antioxidant properties by determination of microsomal NADPH-dependent inhibition of lipid peroxidation levels (LP assay) and microsomal ethoxyresorufin 0-deethylase activity (EROD assay). Some of these compounds 20, 23 had slightly inhibitory effects (28%) on the lipid peroxidation levels at 10(-3)M concentration lower than standard BHT (65%). 5-[2-(Phenyl)-benzimidazol1-yl-methyl]-2-mercapto-[1,3,4]-oxadiazole 16 was found to be more active than caffeine on the ethoxyresorufm 0-deethylase activity with an IC50 value of 2.0 6 10(-4)M.
