Imidazole-based epidermal growth factor receptor (EGFR) inhibitors were computationally designed and synthesized. All the compounds were assessed for their anti-proliferative activity against five cancer cell lines, viz., MDA-MB-231 (breast), T47D (breast) and MCF-7 (breast), A549 (lung) and HT-29 (colorectal). Compounds 2c and 2d emerged as better anticancer molecules with no toxicity towards normal
基于咪唑的表皮生长因子受体 (EGFR) 抑制剂是通过计算设计和合成的。评估了所有化合物对五种癌细胞系的抗增殖活性,即。、MDA-MB-231(乳房)、T47D(乳房)和 MCF-7(乳房)、A549(肺)和 HT-29(结肠直肠)。化合物2c和2d成为更好的抗癌分子,对正常细胞没有毒性。2c和2d在体外抑制EGFR酶活性,IC 50值分别为617.33 ± 0.04 nM和710 ± 0.05 nM。为了进一步提高效力,我们探索了EGFR的ATP结合域的一个未被占用的区域并对其进行了分析2c和2d -EGFR 配合物的计算机相互作用模型,该模型引导并允许在 N-9 位置用 4-(4-甲基哌嗪基)-3-硝基苯基取代 4-氟苯基环(2c和2d ),得到化合物3c具有更好的结合评分和有效的 EGFR 抑制活性 (IC 50 : 236.38 ± 0.04 nM),与阳性对照厄洛替尼 (239.91
