    使用LiCl / LiBr对2-氨基吡啶和2-氨基二嗪进行Selectfluor促进的区域选择性氯化/溴化。
    摘要:
    使用LiCl作为氯源,可以在温和条件下在Selectfluor和DMF存在下建立2-氨基吡啶或2-氨基二嗪的氯化反应。该方法以高至高收率和高区域选择性得到氯化吡啶或二嗪。而且,该方法扩展到通过使用LiBr来溴化2-氨基吡啶或2-氨基二嗪。氯化反应的区域选择性在很大程度上取决于2-氨基吡啶或2-氨基二嗪中的取代基模式。探索了由氯化吡啶合成布帕利西布的方法。对机理的研究表明,这种氯化反应是通过吡啶或二嗪自由基过程进行的。

    咪唑并 [1,2–a] 吡嗪衍生物作为具有强效抗癌活性的微管蛋白聚合抑制剂的设计、合成和生物评价
    摘要:
    通过结构优化和环融合策略,我们设计了一系列新型咪唑并[1,2-a]吡嗪衍生物作为潜在的微管蛋白抑制剂。这些化合物对一组癌细胞系(包括 HepG-2、HCT-116、A549 和 MDA-MB-231 细胞)显示出有效的抗增殖活性(微摩尔到纳摩尔)。其中化合物TB-25对HCT-116细胞的抑制作用最强,IC 50为23 nM。作用机制研究表明,TB-25可有效抑制体外微管蛋白聚合,破坏HCT-116细胞微管的动态平衡。此外,TB-25剂量依赖性地诱导 HCT-116 细胞的 G2/M 期细胞周期停滞和细胞凋亡。此外,TB-25以浓度依赖性方式抑制 HCT-116 细胞迁移。最后,分子对接显示TB-25与微管蛋白的秋水仙碱结合位点吻合良好,并与 CA-4 很好地重叠。总的来说,这些结果表明TB-25代表了一种有前途的微管蛋白抑制剂,值得进一步研究。
