derivatives A1-A25 were synthesized, and their biological activity on tubulin polymerization inhibition and mitotic catastrophe was evaluated. For introducing indole group to CA-4 pattern, the carbohydrazide linker was used for the first time. As the top hit, A18 suggested notable antiproliferation efficacy and tubulin polymerization inhibitory activity. Inferring comparable antitubulin effect with the
在这项工作中,合成了一系列含吲哚的吡唑-碳酰肼衍生物A1-A25 ,并评估了它们对微管蛋白聚合抑制和有丝分裂突变的生物活性。为了将吲哚基团引入 CA-4 模式,首次使用碳酰肼接头。作为最高命中率,A18表明具有显着的抗增殖功效和微管蛋白聚合抑制活性。推断与阳性对照秋水仙碱相当的抗微管蛋白作用,A18表明明显较低的细胞毒性。细胞划痕试验显示A18可以阻断细胞迁移,而共聚焦成像显示A18可以通过类似秋水仙碱的方法诱发有丝分裂灾难。对接模拟可视化了A18的可能结合模式。有了这项工作中的信息,一些关于修改的新提示可能会涉及进一步的微管蛋白相关调查。
