A series of 3-demethoxycarbonyl-3-amide methyl anhydrovinblastine derivatives (5b−24b) was designed, synthesized, and evaluated for their proliferation inhibition activities against two tumor cell lines (A549 and HeLa). Most of the amide anhydrovinblastine derivatives exhibited potent cytotoxicity, with the size of the introduced substituents being the foremost factor in determining the resultant cytotoxic
设计,合成了一系列3-脱甲氧基羰基-3-酰胺甲基脱水长春碱衍生物(5b - 24b),并评估了它们对两种肿瘤细胞系(A549和HeLa)的增殖抑制活性。大多数酰胺脱水长春碱衍生物表现出强的细胞毒性,所引入的取代基的大小是确定所得细胞毒性活性的最主要因素。针对三种有效化合物(6b,12b和24b)对肉瘤180的体内测试结果表明,在脱水长春碱(1e)的22位引入酰胺基可以提高效力和毒性。
