The design, synthesis, and biological evaluation of potent receptor tyrosine kinase inhibitors
摘要:
Variously substituted indolin-2-ones were synthesized and evaluated for activity against KDR, Flt-1, FGFR-1 and PDGFR. Extension at the 5-position of the oxindole ring with ethyl piperidine (compound 7i) proved to be the most beneficial for attaining both biochemical and cellular potencies. Further optimization of 7i to balance biochemical and cellular potencies with favorable ADME/ PK properties led to the identification of 8h, a compound with a clean CYP profile, acceptable pharmacokinetic and toxicity profiles, and robust efficacy in multiple xenograft tumor models.

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。
