ol-5-yl)quinolin-4-amine derivatives were designed and identified as potent inhibitors of VEGFR-2 (KDR) kinase. These compounds with quinoline scaffold and benzimidazole moiety were synthesized and their biological activities against VEGFR-2 and two human cancer cell lines were evaluated. Among them, compound 7s exhibited the most potent inhibitory activity against VEGFR-2 with IC50 of 0.03 μM and
抑制VEGF信号传导途径已成为治疗癌症的有价值的方法。在这项工作中,设计了一系列N-(2-苯基-1 H-苯并[ d ]咪唑-5-基)喹啉-4-胺衍生物并将其鉴定为VEGFR-2(KDR)激酶的有效抑制剂。合成了具有喹啉骨架和苯并咪唑部分的这些化合物,并评估了它们对VEGFR-2和两种人类癌细胞系的生物学活性。其中,化合物7s对VEGFR-2的抑制作用最强,IC 50为0.03μM,对受试癌细胞系的IC 50表现出最高的抗癌活性。针对MCF-7为1.2μM,针对Hep-G2为13.3μM。对接模拟支持最初的药效学假说,并提出了在VEGFR-2 ATP结合位点的共同相互作用方式,这表明化合物7s是潜在的癌症治疗药物,值得进一步研究。
