Quinazolinones are a group of fused heterocyclic compounds which have valuable biological properties including cytotoxic, antibacterial and antifungal activities. Thiazole group-containing compounds have been also reported to have a wide range of biological activities such as antitumor, anti-inflammatory, analgesic and antibacterial effects. Due to valuable cytotoxic effects of both thiazole groups and quinazoline derivatives, in this study a series of quinazolinone-thiazole hybrids were synthesized and evaluated for their cytotoxic effects on three cell lines including MCF-7, HT-29, and PC-3. Among tested compounds (quinazolinones and three intermediates), k5 and k6 showed highest cytotoxic activities against PC3 cell line. K6 and C were most active compounds against MCF7 and K6 showed best cytotoxicity on HT-29 cell line.
