Abstract

Both c-Met and VEGFR-2 are important targets for cancer therapies. Here we report a series of potent dual c-Met and VEGFR-2 inhibitors bearing an anilinopyrimidine scaffold. Two novel synthetic protocols were employed for rapid analoguing of the designed molecules for structure-activity relationship (SAR) exploration. Some analogues displayed nanomolar potency against c-Met and VEGFR-2 at enzymatic level. Privileged compounds 3a, 3b, 3g, 3h, and 18a exhibited potent antiproliferative effect against c-Met addictive cell lines with IC50 values ranged from 0.33 to 1.7 μM. In addition, a cocrystal structure of c-Met in complex with 3h has been determined, which reveals the binding mode of c-Met to its inhibitor and helps to interpret the SAR of the analogues.

摘要

c-Met和VEGFR-2都是癌症治疗的重要靶点。在此,我们报道了一系列带有苯胺嘧啶支架的强效双c-Met和VEGFR-2抑制剂。采用了两种新颖的合成方案来快速模拟设计分子以探索构效关系(SAR)。一些类似物在酶水平上对c-Met和VEGFR-2显示出纳摩尔级别的活性。优势化合物3a、3b、3g、3h和18a对c-Met成瘾性细胞系表现出强效的抗增殖作用,IC50值范围为0.33至1.7μM。此外,还确定了c-Met与3h的共晶体结构,该结构揭示了c-Met与其抑制剂的结合模式,并有助于解释类似物的构效关系。
