oquinazoline derivatives bearing diarylamide moiety were designed, synthesized and evaluated as potent inhibitors of VEGFR-2 kinase. Their in vitro antiproliferation activities against two human cancer cell lines Hep-G2 and MCF-7 have also been determined. Among them, compound 14b exhibited the most potent inhibitory activity against VEGFR-2 with IC50 value of 0.016 ± 0.002 µM and it showed the most
VEGF/VEGFR-2 信号传导在肿瘤血管生成中起关键作用。抑制该途径被认为是一种有前途的癌症治疗方法。在这项工作中,设计、合成和评估了一系列带有二芳基酰胺部分的 6,7-二甲氧基-4-苯胺基喹唑啉衍生物作为 VEGFR-2 激酶的有效抑制剂。它们对两种人类癌细胞系 Hep-G2 和 MCF-7 的体外抗增殖活性也已确定。其中,化合物14b对VEGFR-2的抑制活性最强,IC 50值为0.016 ± 0.002 μM,对Hep-G2和MCF-7的抗增殖作用最强,IC 50低微摩尔范围内的值。分子对接研究表明,以最有效的化合物14b为代表的这些化合物可以很好地与VEGFR-2的ATP结合位点结合,这表明化合物14b可能是一种潜在的靶向VEGFR-2的抗癌剂。
