Abstract

In this study, a series of nitric oxide (NO) -releasing 5-cyano-6-phenyl-2, 4-disubstituted pyrimidine derivatives were designed and synthesized. In the in vitro biological evaluation, compound 24l exhibited optimal antiproliferative activity against MGC-803 cells with the IC50 value of 0.95 µM, significantly better than that of the positive control 5-FU. In addition, preliminary mechanistic studies indicated that 24l inhibited colony formation and blocked MGC-803 cells in the G0/G1 phase. DAPI staining, Reactive Oxygen Species and Apoptosis assays demonstrated that 24l induced Apoptosis of MGC-803 cells. Particularly, the most potent compound 24l produced the highest level of NO, and the antiproliferative activity was significantly reduced after preincubation with NO scavengers. In conclusion, compound 24l may be considered as a potential candidate antitumor agent.
