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。

The invention comprises novel aminopiperidine derivatives, a process for their manufacture, pharmaceutical compositions and the use of such compounds in medicine. In particular, the compounds of formula I prevent the human immunodeficiency virus (HIV) from entering cells by blocking interaction of the viral envelope protein gp120 with a chemokine receptor on the cell surface. The compounds of this invention may be advantageously used as therapeutic agents for the treatment of diseases mediated by the human immunodeficiency virus (HIV), either alone or in combination with other inhibitors of HIV viral replication or with pharmacoenhancers.

Design, synthesis, structure-activity relationships study and X-ray crystallography of 3-substituted-indolin-2-one-5-carboxamide derivatives as PAK4 inhibitors
We have previously described the identification of indolin-2-one-5-carboxamides as potent PAK4 inhibitors. This study expands the structure-activityrelationships 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
