Design, synthesis and antitumor activity evaluation of 5-cyano-2,4,6-substituted pyrimidine derivatives containing acrylamide group

A series of novel 5-cyano-2,4,6-substituted pyrimidine derivatives containing acrylamide group were designed, synthesized, and evaluated for their antitumor activity against four human cancer cell lines (MGC-803, PC-3, A549, and H1975) using the MTT assay. Among them, compound 20y exhibited the most potent cytotoxicity against PC-3 cells (IC 50 ?=?2.75?±?0.08?μM). Notably, compound 20y significantly inhibited the colony formation, migration, and invasion of PC-3 cells. Furthermore, compound 20y induced S-phase cell cycle arrest and apoptosis in PC-3 cells. These findings indicate that compound 20y might serve as a valuable lead compound for developing antitumor agents targeting prostate cancer cells. Graphical Abstract
