  发现了新型的基于联芳基磺酰胺的Mcl-1抑制剂。

  摘要：

  Mcl-1是在血液系统恶性肿瘤和几种人类实体瘤中过表达的抗凋亡蛋白。Mcl-1的小分子抑制将为Mcl-1介导的耐药性提供有效的治疗方法。随后，它已成为制药行业广泛研究的目标。首先描述了从高通量筛选中获得的简单的联芳基磺酰胺命中，发现了新型的Mcl-1小分子抑制剂。SBDD辅助的药物化学作用产生了能够在体外破坏Mcl-1 / Bid蛋白质-蛋白质相互作用的化合物。Mcl-1结合的配体的晶体结构代表与BH3结合袋的独特结合模式，其中部分通过磺酰胺氧/ Arg263相互作用获得结合亲和力。这项工作强调了为Bcl-2类蛋白质设计有效的蛋白质-蛋白质抑制剂时面临的一些关键挑战。

  嘧啶衍生物及其制备方法、用途

  摘要：

  本发明的嘧啶衍生物含有芳香五元杂环，杂原子S、O或N上的孤电子对一方面与不饱和五元环形成共轭体系，另一方面由于这些杂原子的孤电子对效应，对血管内皮生长因子受体VEGFR‑1、VEGFR‑2、VEGFR‑3具有抑制作用，因此该嘧啶衍生物是一类很好的激酶抑制剂。本发明的嘧啶衍生物对VEGFR1、VEGFR2和VEGFR3的抑制活性要强于现有技术的帕唑帕尼，其可用于抑制血管内皮生长因子(VEGF)信号通路的疾病如肺癌、肾细胞癌和其它实体瘤等的治疗。
