c-Met and VEGFR-2 have attracted interest as novel targets for treatment of various cancers. Aiming to develop potent dual c-Met and VEGFR-2 inhibitors, a series of pyrrolo[1,2-f][1,2,4]triazine derivatives were designed and synthesized. The majority of target compounds exhibited potent antiproliferative effect against c-Met addictive cancer cell lines with IC50 values ranged from 1.2 to 24.6 nM, especially
作为治疗各种癌症的新靶标,c-Met和VEGFR-2引起了人们的兴趣。为了开发有效的双重c-Met和VEGFR-2抑制剂,设计并合成了一系列吡咯并[1,2- f ] [1,2,4]三嗪衍生物。大多数目标化合物对c-Met成瘾的癌细胞系表现出有效的抗增殖作用,IC 50值范围为1.2至24.6 nM,尤其是27a。深入研究表明,27a对c-Met和VEGFR-2具有很高的选择性,并且对它们具有强大的抑制活性(IC 50为2.3±0.1 nM和5.0±0.5 nM)。此外,IC 50还显示出最高的抗癌活性BaF 3 -TPR-Met的0.71±0.16 nM(优于阳性化合物)和HUVEC-VEGFR2的37.4±0.311 nM(与阳性化合物相比),与c-Met敏感肿瘤细胞系中的一致。随后,理化和药代动力学表征表明27a具有良好的可药性和药代动力学性质。进一步的对接研究表明,在c-Met和VE
