New EGFR inhibitor series of fifteen 5-chloro-3-hydroxymethyl-indole-2-carboxamide derivatives has been designed, synthesized, and tested for antiproliferative activity against a panel of cancer cell lines. The results showed that p-substituted phenethyl derivatives 10, 11, 13, 15 and 17-19 showed superior antiproliferative activity compared to their m-substituted counterparts 12, 14, 16 and 20. Compounds
15 种 5-氯-3-羟甲基-吲哚-2-甲酰胺衍生物的新型 EGFR 抑制剂系列已被设计、合成并测试其对一组癌细胞系的抗增殖活性。结果表明,p取代的苯乙基衍生物10,11,13,15和17-19相比,其表现出优异的抗增殖活性的米-取代的对应物12,14,16和20。化合物15,16,19和20显示出有希望的 EGFR 抑制活性以及半胱天冬酶 3 水平的增加。化合物15和19增加了 caspase-8 和 9 的水平,以及诱导 Bax 和降低 Bcl-2 蛋白水平。化合物19在前 G1 和 G2/M 阶段表现出细胞周期停滞。与 EGFR 活性位点对接研究的结果表明,与厄洛替尼相比,具有更高结合亲和力的新化合物具有很强的拟合能力。
