In an attempt to explore a new class of epidermal growth factor receptor (EGFR) inhibitors, novel 4-stilbenylamino quinazoline derivatives were synthesized through a Dimorth rearrangement reaction and characterized via IR, ¹H-NMR, C-NMR, and HRMS. Methoxyl, methyl, halogen, and trifluoromethyl groups on stilbeneamino were detected. These synthesized compounds were evaluated for antitumor activity in vitro against eight human tumor cell lines with an MTS assay. Most synthesized compounds exhibited more potent activity (IC = ~2.0 μM) than gefitinib (IC > 10.0 μM) against the A431, A549, and BGC-823 cell lines. Docking methodology of compound 6c and 6i binding into the ATP site of EGFR was carried out. The results showed that fluorine and trifluoromethyl played an important role in efficient cell activity.
为了探索新型表皮生长因子受体 (EGFR) 抑制剂，我们通过Dimorth 重排反应合成了新型 4-二苯乙烯基氨基喹唑啉衍生物，并通过 IR、1H-NMR、C-NMR 和高分辨质谱进行了表征。检测到二苯乙烯基氨基上的甲氧基、甲基、卤素和三氟甲基。采用 MTS 法测定了这些合成化合物对 8 个人类肿瘤细胞系的体外抗肿瘤活性。大多数合成化合物对 A431、A549 和 BGC-823 细胞系的活性（IC = ~2.0 μM）强于吉非替尼（IC > 10.0 μM）。对化合物 6c 和 6i 与 EGFR 的 ATP 结合部位进行了对接方法研究。结果表明，氟和三氟甲基在高效细胞活性中起着重要作用。
