A series of novel 4-arylamino-6-(5-substituted furan-2-yl)quinazoline derivatives were designed, synthesized and evaluated on biological activities in vitro. Compound 2a, 3a and 3c exhibited highly anti-proliferation activities on all tested tumor cell lines including SW480, A549, A431 and NCI-H1975 cells. Especially, compound 2a not only exhibited strong anti-proliferation activities against the tumor
设计,合成了一系列新型的4-芳基氨基-6-(5-取代的呋喃-2-基)喹唑啉衍生物,并对其体外生物活性进行了评价。化合物2a,3a和3c在所有测试的肿瘤细胞系(包括SW480,A549,A431和NCI-H1975细胞)上均表现出高度的抗增殖活性。特别地,化合物2a不仅对表达野生型或突变型EGFRL858R / T790M的肿瘤细胞系表现出强的抗增殖活性,而且还显示出对野生型EGFR的最有效的抑制活性(IC 50 = 5.06nM)。与EGFR对接的结果表明2a的结合模式与拉帕替尼相似。Western印迹分析显示2a在指定浓度下能明显抑制肺癌细胞中EGFR,Akt和Erk1 / 2的活化。
