the EGFR wild‐type A431 cells and 5c with an IC50 of 0.001 μm against the gefitinib‐sensitive HCC827 cells (EGFR del E746‐A750) was identified as highly active EGFR inhibitors. It was also significant that the discovered analogue 2f, not only has high potency against the gefitinib‐sensitive cells (IC50 = 0.031 μm), but also possesses remarkably improved activity against the gefitinib‐resistant cells
合成了一类带有各种C-4苯胺部分的新型喹唑啉衍生物,并对其进行了生物学评估,认为它们是有效的表皮生长因子受体(EGFR)抑制剂,可用于治疗非小细胞肺癌(NSCLC)。这些抑制剂中的大多数在抑制这些癌细胞系方面与吉非替尼相当,其中一些甚至表现出优异的抑制活性。特别地,模拟图5b与IC 50 0.10 μ米针对EGFR野生型A431细胞和5c中有一个IC 50 0.001的μ米对吉非替尼敏感的HCC827细胞(EGFR del E746‐A750)的抗性被确定为高活性EGFR抑制剂。它也是显著所发现的类似物2F,不仅具有对吉非替尼敏感性细胞的高效力(IC 50 = 0.031 μ米),但也具有显着的对抗吉非替尼抗性细胞改善的活性。另外,用于评估典型抑制剂作用的酶促测定和蛋白质印迹分析表明,这些分子强烈干扰EGFR靶标。
