Microtubule-targeted drugs play a critical role in various types of cancer therapy worldwide. In our study, a series of novel indole derivatives containing a sulfonamide scaffold were designed, synthesized and biologically evaluated as potential tubulin polymerization inhibitors. Among them, compound 18 displayed the most potent inhibitory effect on antiproliferative activity against four types of
以微管为靶标的药物在世界范围的各种癌症治疗中都起着关键作用。在我们的研究中,设计,合成了一系列含有磺酰胺支架的新型吲哚衍生物,并对其进行了生物学评估,以作为潜在的微管蛋白聚合抑制剂。其中,化合物18对四种类型的人类癌细胞系(IC 50值为0.24-0.59μM)和微管蛋白组装(IC 50 = 1.82μM)表现出最强的抑制作用。进一步的研究表明,化合物18是HeLa细胞凋亡的有效诱导剂,并可能在细胞周期的G2 / M期引起细胞停滞。分子对接和共聚焦显微镜分析结果表明该化合物18可以与微管蛋白的秋水仙碱结合位点紧密结合,并起微管蛋白聚合抑制剂的作用。还建立了3D-QSAR模型以提供更多信息,这些信息可用于设计具有更强微管蛋白抑制活性的新分子。
