A series of novel quinazolinone derivatives containing a substituted amino moiety were synthesized, evaluated for their cytotoxic and antibacterial activities. The results of MTT assay showed that all synthesized target compounds 5A?–?5O showed potent cytotoxicity against SGC-7901 (IC50, 0.72?–?1.41?μm). Moreover, the compounds 5D, 5I, and 5K showed better selectivity as compared with positive controls pemetrexed and MTX due to weak cytotoxicity against normal tissue cell line HUVSMC. Among synthesized compounds, the compounds 5E, 5J, 5L, and 5N showed broad-spectrum cytotoxic activities against at least four cancer cell lines at a micromolar level. The results of antibacteria evaluation revealed that all synthesized compounds showed good to moderate antibacterial activities against Gram-negative bacteria Escherichia coli. Among them, the MIC values of the compounds 5C, 5F, and 5M were 0.31?μg/mL.
