tumors, but with unmanageable side effects. Design approach and selectivity of these inhibitors plays substantial role in their potency and side-effects. Understanding the homology of binding sites in targeted receptors, and involvement of signaling proteins after the inhibition might help in producing less toxic but effective inhibitors. Herein, we designed benzylideneindolon-2-one derivatives based
双 TK 抑制剂已对许多肿瘤显示出显着的临床效果,但具有无法控制的副作用。这些抑制剂的设计方法和选择性在其效力和副作用方面起着重要作用。了解靶向受体中结合位点的同源性以及抑制后信号蛋白的参与可能有助于产生毒性较小但有效的抑制剂。在此,我们基于 VEGFR-2 和 EGFR 受体结合位点的同源性建模设计了亚苄基吲哚酮-2-one 衍生物,作为具有高选择性的双重抑制剂有效抗癌化合物。发现benzylideneindolon-2-one 衍生物以oxindole 的形式具有构象转换,在2-benzimidazole 处被取代。在合成的化合物中,发现5b在针对 VEGFR-2 和 EGFR的体外酶抑制试验,最高 IC 50值分别为6.81 ± 2.55和13.04 ± 4.07 nM。有趣的是,细胞毒性研究揭示了化合物5b对 A-431 细胞系(过度表达的 VEGFR-2 和 EGFR)增殖的选择性毒性,GI
