We have previously described the identification of indolin-2-one-5-carboxamides as potent PAK4 inhibitors. This study expands the structure-activity relationships on our original series by presenting several modifications in the lead compounds, 2 and 3. A series of novel derivatives was designed, synthesized, and evaluated in biochemical and cellular assay. Most of this series displayed nanomolar biochemical
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。
