In this work, a series of diaryl benzo[b][1,4]thiazepine derivatives D1-D36 were synthesized and screened as tubulin polymerization inhibitors with anti-tumor potency. They were designed by introducing the seven-member ring benzothiazepine as the linker for CA-4 modification for the first time. Among them, the hit compound D8 showed potential on inhibiting the growth of several cancer cell lines (IC50
在这项工作中,合成并筛选了一系列二芳基苯并[ b ] [1,4] 硫氮杂衍生物D1-D36作为具有抗肿瘤效力的微管蛋白聚合抑制剂。它们是通过首次引入七元环苯并噻嗪作为 CA-4 修饰的接头而设计的。其中,命中化合物D8显示出抑制多种癌细胞系生长的潜力(IC 50值:HeLa 1.48 μM,MCF-7 1.47 μM,HT29 1.52 μM 和 A549 1.94 μM),与阳性对照秋水仙碱和CA-4P。D8的计算 IC 50值作为微管蛋白聚合抑制剂的浓度为 1.20 μM。流式细胞术检测结果表明,D8可以诱导有丝分裂灾难和活癌细胞的死亡。D8还表明了抗血管活性。对接模拟暗示了可能的结合模式,推断引入与附近微管蛋白链相互作用的可能性。由于新的结构试验已经进行了初步讨论,这项工作可能会激发进一步修改微管蛋白相关抗癌药物和治疗方法的新思路。
