  设计，合成，结构-活性关系研究和X射线晶体学的3-取代的吲哚-2-二-5-羧酸酰胺衍生物作为PAK4抑制剂

  摘要：

  先前我们已经描述了将吲哚啉-2-一-5-羧酰胺确定为有效的PAK4抑制剂。这项研究通过对先导化合物2和3进行一些修饰，扩展了我们原始系列的构效关系。在生化和细胞分析中设计，合成和评估了一系列新型衍生物。该系列中的大多数显示出针对A549和HCT116细胞的纳摩尔生化活性和有效的抗增殖活性。代表性化合物10a表现出优异的酶抑制作用（PAK4 IC 50  = 25 nM）和细胞效价（A549 IC 50  = 0.58μM，HCT116 IC 50  = 0.095μM）。化合物的X射线结构获得与PAK4结合的10a。晶体学分析证实了分子模型的预测，并有助于改进SAR结果。另外，化合物10a显示出集中的多靶点激酶抑制作用，良好的计算药物相似性。化合物10a的进一步分析表明，它对人细胞色素P450的各种同工型均显示出弱的抑制活性。
