Virtual screening of commercially available molecular entities by using CDRUG, structure-based virtual screening, and similarity identified eight new derivatives of 3-phenyl-1H-indole-2-carbohydrazide with anti-proliferative activities. The molecules were tested experimentally for inhibition of tubulin polymerisation, which revealed furan-3-ylmethylene-3-phenyl-1H-indole-2-carbohydrazide (27a) as the
通过使用 CDRUG、基于结构的虚拟筛选和相似性对市售分子实体进行虚拟筛选,确定了 8 种具有抗增殖活性的 3-phenyl-1 H -indole-2-carbohydrazide新衍生物。通过实验测试这些分子对微管蛋白聚合的抑制作用,结果表明呋喃-3-基亚甲基-3-苯基-1 H-吲哚-2-碳酰肼(27a)是最有效的候选物。分子27a能够在 A549 细胞系中诱导 G2/M 期阻滞,类似于其他微管蛋白抑制剂。27a 的合成修饰集中在呋喃环上的小取代、R 1 处的卤化Furyl 连接的位置和改变。衍生物27b、27d和27i表现出最强的微管蛋白抑制活性并且与27a相当。R 1位的溴取代显示出最突出的抗癌活性;衍生物27b-27d对 HuCCA-1 细胞系表现出最强的活性,并且比阿霉素和母体分子27a更有效,IC 50值 <0.5 μM。值得注意的是,在呋喃上具有 5-甲氧基取代的27b对 HepG2
