The influence of the incorporation of 1,3,4-oxadiazole ring into 2-methyl-1H-benzimidazole derivatives producing a series of substituted 5(6)-(2-methylbenzimidazol-5-yl)-1,3,4-oxadiazoles on the antitumor activity was studied in this study. The antitumor activity of the new compounds was tested against breast cancer cell line MCF-7 and lung cancer cell line A549. S-5-(2-methyl-1H-benzo[d]imidazol-5-yl)-1,3,4-oxadiazol-2-yl 2-nitrobenzenesulfonothioate (9) showed potent activity against both MCF-7 and A549 cell lines. Whereas, compounds 7, 11-13 and 15-17 have moderate growth inhibitory activity on the two cell lines.
