A series of novel 3-benzylcoumarin-imidazolium salts were prepared and evaluated in vitro against a panel of human tumor cell lines. The results showed that the existence of 5,6-dimethyl-benzimidazole ring and substitution of the imidazolyl-3-position with a naphthylacyl group were vital for modulating cytotoxic activity. Notably, compound 38 was found to be the most potent derivative with IC50 values
制备了一系列新颖的3-苄香豆素-咪唑鎓盐,并在体外针对一组人类肿瘤细胞系进行了评估。结果表明5,6-二甲基苯并咪唑环的存在和咪唑基-3-位被萘甲酰基取代对于调节细胞毒性活性至关重要。值得注意的是,发现化合物38是针对五种人类肿瘤细胞系的最有效衍生物,IC50值为2.04-4.51μM,而化合物34对SW-480细胞系的选择性更高,IC50值比DDP低40.0倍。作用机理研究表明,化合物38可以导致SMMC-7721细胞株G0 / G1期细胞周期停滞和凋亡。
