In the present study, a new series of 3,4- dihydropyrmidine2-(1 H) one derivatives(4a-f) which linked to 2-mercapto-3-phenyl-4(3H)-quinazolinone were synthesized by using the nucleophilic substitution reaction of 2-mercapto-3-phenyl-4(3H)-quinazolinone (1) and an appropriate 6-bromomethyl-3,4- dihydropyrmidine2-(1 H) one (3a-f) in the presence of KOH as base and in CH3CN as solvent. The chemical structures of the synthesized compounds were confirmed by means of IR, 1H-NMR, 13C-NMR, Mass spectroscopy, and Elemental analysis. The cytotoxicity of the newly synthesized compounds was evaluated in vitro against the human breast cancer (MCF-7) cell line and human colon cancer cell line (HT-29) based on the results of the MTT assay. Our results indicated that the compound 4b exerted the most cytotoxic effect in the two cell lines and the IC50 values were (4.25±0.16 μM) for MCF-7 cell lines and (12.11±0.76 μM) for HT-29 cell lines. Also, compound 4b induced apoptosis more than other compounds in the two cell lines. Thus, compound 4b may be had a potential anticancer agent.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
