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 thieno[2,3-d]pyrimidine scaffold. The cell proliferation assay in vitro demonstrated that most target compounds had inhibition potency both on c-Met and VEGFR-2 with IC50 values in nanomolar range, especially compound 12j and 12m. Based on the further enzyme
c-Met和VEGFR-2都是癌症治疗的重要靶标。在这里,我们报告一系列有效的双重c-Met和VEGFR-2抑制剂,带有噻吩并[2,3- d ]嘧啶骨架。体外细胞增殖试验表明,大多数目标化合物对c-Met和VEGFR-2均具有抑制作用,IC 50值在纳摩尔范围内,尤其是化合物12j和12m。根据进一步的体外酶分析,化合物12j被认为是最有效的化合物,其c-Met和VEGFR-2的IC 50值分别为25 nM和48 nM。之后,我们将化合物12j停靠与蛋白质c-Met和VEGFR-2结合,并解释了这些类似物的SAR。所有结果表明,12j是c-Met和VEGFR-2的双重抑制剂,具有广阔的发展前景。
