potent derivative towards HepG2 cells (IC50 = 2.67 ± 0.14 μM), 6r stood out as the most potent indolinone against A498 cells (IC50 = 0.78 ± 0.02 μM). Additionally, the target indolinones displayed non-significant cytotoxic impact towards human normal melanocyte (HFB4). ADME prediction study of the designed compounds showed that they are not only with promising multikinase inhibitory activity but also
基于我们对开发新型多激酶抑制剂的努力,在此我们报告了新型基于2-吲哚满酮的酰脲6a-u和酰胺10a - j的设计和合成。在这项工作中,我们采用IIA型PTK抑制剂(索拉非尼)和IIB型PTK抑制剂(舒尼替尼和nintedanib)之间的杂交策略。这是通过以下方式实现的舒尼替尼和nintedanib中的吲哚酮核心之间的连接非常合适,而索拉非尼中的茚满酮核心适合于激酶结构域前裂的铰链区和联芳基脲延伸区,而索拉非尼则位于门区域和疏水性后袋中。按照计划,设计的杂合化合物在VEGFR-2和FGFR-1活性位点上的分子对接揭示了它们建立由原始IIA型和IIB型抑制剂实现的结合相互作用的能力。评价所设计的化合物对VEGFR-2,PDGFR-b和FGFR-1的多激酶抑制活性以及对HepG2,MCF-7,A549和A498癌细胞系的抗增殖活性。脲基类似物6u成为具有VEGFR-2,FGFR-1和PDGFR-b
