substituent or 2-naphthylacyl substituent, were important to the cytotoxic activity. Notably, 3-(2-Naphthylmethyl)-1-((2,3,6,7-tetrahydrobenzo[1,2-b;4,5-b']difuran-4-yl)methyl)-1H-5,6-dimethyl-benzimidazol-3-ium bromide (42) was found to be the most potent derivative against five human tumor cell lines with IC50 values of 1.06-4.34μM and more selective towards SMMC-7721, A549 and SW480 cell lines. 3-(2-Naphthylacyl)-1-((2
提出了一系列新颖的4-取代的2,3,6,7-四氢苯并[1,2-b; 4,5-b']二呋喃-1H-咪唑鎓盐的合成。在体外针对一组人类肿瘤细胞系评估了化合物的生物学特性。结果表明5,6-二甲基苯并咪唑环或2-甲基苯并咪唑环以及用2-萘甲基取代基或2-萘甲酰基取代基取代咪唑基-3-位对于细胞毒性活性是重要的。值得注意的是,3-(2-萘基甲基)-1-(((2,3,6,7-四氢苯并[1,2-b; 4,5-b']二呋喃-4-基)甲基)-1H-5,发现六甲基二甲基苯并咪唑-3-溴化铵(42)是针对五种人类肿瘤细胞系的最有效衍生物,IC50值为1.06-4.34μM,对SMMC-7721,A549和SW480细胞系更具选择性。3-(2-萘甲酰基)-1-(((2,3,6,7-四氢苯并[1,2-b; 4,5-b']二呋喃-4-基)甲基)-1H-2-甲基苯并咪唑-3-溴化铵(37)对SMMC-7721和MCF-
