against HepG2 cell. All synthesized compounds were evaluated for anti-angiogenesis capability. Compound 7o showed the most potent anti-angiogenesis ability, the efficient cytotoxic activities (in vitro against HUVEC and HepG2 cell lines with IC50 values of 0.58 and 0.23 µM, respectively). The molecular docking analysis revealed 7o is a Type-II inhibitor of VEGFR-2 kinase. In general, these results indicated
本文中,我们以先前报道的XL-6f为先导化合物,着手进行结构优化运动,旨在发现新型抗癌药。基于VEGFR-2高度保守的活性位点,已合成了23种化合物的文库。几种标题化合物显示出对VEGFR-2的选择性抑制活性,还显示出对HepG2细胞的选择性抗增殖能力。评价所有合成的化合物的抗血管生成能力。化合物7o显示出最有效的抗血管生成能力和有效的细胞毒活性(体外针对HUVEC和HepG2细胞系,IC 50值分别为0.58和0.23 µM)。分子对接分析显示7o是VEGFR-2激酶的II型抑制剂。通常,这些结果表明这些芳基酰胺-5-苯胺基喹唑啉-8-硝基衍生物是用于潜在治疗抗血管生成的VEGFR-2抑制剂。
