to a 4-anilinoquinazoline nucleus have been discovered as potential EGFR inhibitors. These compounds proved efficient effects on antiproliferative activity and EGFR–TK inhibitory activity. Especially, N6-((5-bromothiophen-2-yl)methyl)-N4-(3-chlorophenyl)quinazoline-4,6-diamine (5e), showed the most potent inhibitory activity (IC50 = 3.11 μM for Hep G2, IC50 = 0.82 μM for A549). The EGFR molecular docking
已发现含有与4-苯胺基喹唑啉核连接的6-氨基取代基或6-丙烯酰胺取代基的两个新系列新化合物。这些化合物被证明对抗增殖活性和EGFR-TK抑制活性有效。尤其是N 6 -((5-溴噻吩-2-基)甲基)-N 4-(3-氯苯基)喹唑啉-4,6-二胺(5e)表现出最强的抑制活性(IC 50 = 3.11μM Hep G2,IC 50 对于A549 = 0.82μM)。EGFR分子对接模型表明该新化合物与EGFR区域结合良好,Hoechst染色实验的细胞形态表明这些化合物可有效诱导A549细胞凋亡。
