(ATP)-competitive inhibitors of the epidermal growth factor receptor (EGFR) have provided a significant improvement in the disease outcome of nonsmall cell lung cancer (NSCLC). Unfortunately, some marketed drugs affect a transient beneficial response in EGFR mutant NSCLC patients. We reported a series of potential EGFR inhibitors through incorporation of macrocyclic polyamine into 4-anilinoquinazoline scaffold
表皮生长因子受体(EGFR)的三磷酸腺苷(ATP)竞争性抑制剂已大大改善了非小细胞肺癌(NSCLC)的疾病预后。不幸的是,某些市售药物会影响EGFR突变型NSCLC患者的短暂有益反应。我们通过将大环多胺掺入4-苯胺基喹唑啉支架中,报道了一系列潜在的EGFR抑制剂。预期苯胺基喹唑啉部分有效结合至EGFR域,而ATP分子被大环多胺部分捕获。体外实验显示,大多数测试化合物比吉非替尼和拉帕替尼(EGFR / HER2的双重抑制剂)抑制肿瘤细胞增殖的能力更强。在激酶测定中,化合物1f对EGFR WT(IC 50 = 1.4 nM)和HER2(IC 50 = 2.1 nM)表现出优异的双重抑制活性。1f的体内药理学评估显示,A549异种移植小鼠具有显着的抗肿瘤活性(TGI = 44.2%)。当前的工作为优化基于苯胺喹唑啉的抑制剂提供了可行的解决方案。
