carboxamide 1, chosen as reference. Potent inhibitions were observed on both tests in the carboxamide series, particularly for compound 4d bearing a fluorine group in replacement of the 3-hydroxyl of CA4. In contrast, most of the carbamates were either inactive or displayed only moderate cytotoxicities. Interestingly, a submicromolar IC(50) was measured on MCF-7 cells for 6g, although this compound was totally
为了改善水溶性和稳定双键的顺式构型,合成了两种康普他汀A4衍生物(丙烯酰胺=羧酰胺和氨基甲酸酯)。评估了它们对MCF-7,KB-3-1和IGROV人癌细胞系的细胞毒性作用,以及它们对微管蛋白聚合的抑制活性。将结果与选择的羧酰胺1的结果进行比较。在羧酰胺系列的两个试验中均观察到了强力抑制作用,特别是对于带有氟基团的化合物4d替代了CA4的3-羟基。相反,大多数氨基甲酸酯要么是无活性的,要么仅表现出中等的细胞毒性。有趣的是,尽管该化合物完全没有抗微管蛋白活性,但在MCF-7细胞上测得亚微摩尔IC(50)为6g。
