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
本研究设计并合成了一系列释放一氧化氮(NO)的5-氰基-6-苯基-2,4-二取代嘧啶衍生物。体外生物学评价中,化合物24l对MGC-803细胞表现出最佳的抗增殖活性,IC 50值为0.95 μM,明显优于阳性对照5-FU。此外,初步机制研究表明24l抑制集落形成并阻断MGC-803细胞处于G0/G1期。DAPI染色、活性氧和细胞凋亡测定表明24l诱导MGC-803细胞凋亡。特别是,最有效的化合物24l产生最高水平的NO,并且与NO清除剂预孵育后,抗增殖活性显着降低。总之,化合物24l可被认为是潜在的候选抗肿瘤剂。
