A series of novel hexahydropyrrolo[2,3-b]indole–1H-imidazolium salts were synthesized and evaluated in vitro against a panel of human tumor cell lines. The results suggest that the 5,6-dimethyl-benzimidazole ring, and substitution of the imidazolyl-3-position with a 2-bromobenzyl or 2-naphthylmethyl group, were important for the cytotoxic activity. Notably, Compound 43, bearing a 2-bromobenzyl substituent
合成了一系列新颖的六氢吡咯并[2,3 - b ]吲哚-1 H-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-苯并咪唑环以及用2-溴苄基或2-萘甲基甲基取代咪唑基-3-位对于细胞毒性活性是重要的。值得注意的是,发现化合物43在5,6-二甲基-苯并咪唑的3位带有2-溴苄基取代基,对五种人类肿瘤细胞系具有最有效的衍生物,IC 50值低于2.68μM,对SMMC的选择性更高-7721,A549和SW480细胞系。化合物25和39对HL-60和MCF-7细胞系具有更高的选择性,IC 50值为0.47和1.46μM。
