By combining the structural features of quinazoline and benzimidazole, new hybrid regioisomeric molecules with substituted primary amines have been synthesized. Evaluation of these molecules over 60 cancer cell line panel has identified three molecules as most potent anticancer agents. Compound 10 showed ten and eleven folds more activity than respective quinazoline and benzimidazole class of compounds with GI(50) value of 1.64 mu M. Compound 11 (GI(50) value of 0.81 mu M) showed almost twenty and twenty-two fold more activity than quinazoline and benzimidazole analogue, respectively while compound 12 (GI(50) value of 4.52 mu M) has four fold more activity than quinazoline and benzimidazole analogue. In vitro evaluation of compound 11 exhibited remarkable anticancer activity towards colon cancer cell lines and prostate cancer cell lines at five dose concentrations with GI(50) values of 0.34 and 0.31 mu M, respectively.
