zole derivatives has been designed and synthesized based on the highly conserved active site of VEGFR-2. Several title compounds exhibited selective inhibitory activities against VEGFR-2 than EGFR kinases, which also displayed selective anti-proliferation potency against the HUVEC and HepG2 than the A549 and MDA-MB-231 cancer cell lines. The newly synthesized compounds were evaluated for anti-angiogenesis
在本文中,我们进行了结构优化,以使用我们先前筛选的YQY-26作为命中化合物来发现新型抗肿瘤药。基于VEGFR-2高度保守的活性位点,设计并合成了37种6-酰胺-2-芳基苯并恶唑/苯并咪唑衍生物的文库。与EGFR激酶相比,几种标题化合物对VEGFR-2表现出选择性抑制活性,与A549和MDA-MB-231癌细胞系相比,对HUVEC和HepG2也表现出选择性的抗增殖潜能。通过鸡绒膜尿囊膜(CAM)测定评估了新合成的化合物的抗血管生成能力。其中,化合物9d表现出最强的抗血管生成能力(在10 nM / eggs时抑制率达79%),有效的细胞毒性活性(在体外对HUVEC和HepG2细胞系的IC 50值分别为1.47和2.57μM)和出色的VEGFR- 2种激酶抑制(IC 50 = 0.051μM)。分子对接分析表明,化合物9d是VEGFR-2激酶的II型抑制剂。这些结果表明6-酰胺-2-芳基苯并
