double mutant epidermal growth factor receptor (EGFR), but also showed potent inhibitory activity against wild type EGFR (IC50 = 20.72 nM). The result of molecular docking with EGFR suggested the binding mode of 6e was similar to gefitinib, but different from lapatinib. Additionally, western blot analysis showed that 6e inhibited the phosphorylation of EGFR and its downstream signaling proteins in lung
设计,合成了一系列具有(E)-丙烯-1-基部分的新型4-苯胺基喹唑啉衍生物,并对其体外生物活性进行了评估。大多数化合物对包括A431,A549,NCI-H1975和SW480细胞在内的所有测试肿瘤细胞系均表现出高度抗增殖活性。尤其是,化合物6e不仅对测试的四种表达野生型或L858R / T790M双突变表皮生长因子受体(EGFR)的肿瘤细胞系(IC 50分别为1.35、8.83、5.53和6.08μM)表现出强大的抗增殖活性,但也显示出对野生型EGFR(IC 50 = 20.72 nM)。与EGFR分子对接的结果表明6e的结合模式与吉非替尼相似,但与拉帕替尼不同。此外,蛋白质印迹分析表明6e抑制了肺癌细胞中EGFR及其下游信号蛋白的磷酸化。这项工作对于开发针对EGFR的新系列酪氨酸激酶抑制剂可能是非常有用的起点。
