A series of novel structurally-related tubulin polymerization inhibitors based on benzodiazepine were designed, synthesized, and evaluated for anticancer activity. Extensive structure modifications were performed to investigate the detailed structure and activity relationships (SARs). Most compounds exhibited potent antiproliferative activity against a panel of cancer cell lines. Among these compounds
设计,合成并评估了一系列基于苯并二氮杂的新型结构相关的微管蛋白聚合抑制剂,并评估了其抗癌活性。进行了广泛的结构修改,以调查详细的结构和活动关系(SAR)。大多数化合物对一组癌细胞显示出有效的抗增殖活性。在这些化合物中,最佳化合物9a具有最优异的活性,包括对五种癌细胞系的细胞毒性(IC50 = 6-15 nM)和微管蛋白聚合的抑制作用(IC50 = 1.65±0.11μM)。机理研究表明,9a可能破坏细胞内微管的组织,将细胞周期阻滞在G2 / M期,并最终诱导细胞凋亡。化合物9a表现出良好的代谢稳定性,t1 / 2为161.2分钟,它比参考化合物CA-4更好。此外,9a,9a-P的二钠盐在异种移植小鼠模型中表现出优异的体内抗肿瘤活性,抑制率为89.3%,优于参考化合物CA-4P(抑制率:52.8%)和Y-01P。 (抑制率:77.7%)。总之,9a可以用作开发高效抗癌药的有前途的先导化合物。
