  高效微管蛋白聚合抑制剂的发现：新型 2,7-二芳基-[1,2,4] 三唑并 [1,5-a] 嘧啶的设计、合成和构效关系

  摘要：

  通过去除我们之前报道的化合物3 中的5-甲基和 6-乙酰基，我们设计了一系列新型 2,7-二芳基-[1,2,4] 三唑并 [1,5- a ] 嘧啶衍生物作为潜在的微管蛋白聚合抑制剂。其中，化合物5e对 HeLa 细胞显示出低纳摩尔的抗增殖功效，比铅类似物3高 166 倍。有趣的是，与 HEK-293（正常人胚胎肾细胞）相比，5e在抑制癌细胞方面表现出显着的选择性。此外，5e通过改变 p-cdc2 和细胞周期蛋白 B1 的表达水平，剂量依赖性地将 HeLa 阻滞在 G2/M 期，并通过调节裂解的 PARP 的表达导致 HeLa 细胞凋亡。进一步的证据表明，5e有效地抑制了微管蛋白聚合，并且比阳性对照 CA-4 强 3 倍。此外，分子对接分析表明，5e与秋水仙碱结合位点中的 CA-4 重叠良好。这些研究表明，2,7-二芳基-[1,2,4]三唑并[1,5- a ]嘧啶骨架可用作开发新型微管蛋白聚合抑制剂作为潜在抗癌剂的主要单元。

  The synthesis and antiviral activity of a series of novel polycyclic analogues of the orthopoxvirus egress inhibitor tecovirimat (ST-246) is presented. Several of these compounds display sub-micromolar activity against vaccinia virus, and were more potent than cidofovir (CDV). The more active compounds were about 10-fold more active than CDV, with minimum cytotoxic concentrations above 100 μM. Chemical
