evaluated as wild type (WT) and mutant EGFR inhibitors. Most of the compounds inhibited EGFR kinase wild type (EGFR WT) with IC50 values in the low nanomolar range (<0.495–9.05 nM) and displayed more potent cytotoxic effect in BaF/3 expressing EGFR WT than reference compound gefitinib. The anti-proliferative effect of all synthesized compounds against gefitinib insensitive double mutant cell lines Ba/F3
设计,合成和评价了具有C-6脲基和硫脲基侧链以及在C-4苯胺基部分具有各种取代基的一系列新的4-苯胺基喹唑啉,并将其评估为野生型(WT)和突变型EGFR抑制剂。大多数化合物抑制EGFR激酶野生型(EGFR WT)的IC 50值都在低纳摩尔范围(<0.495–9.05 nM),并且比参考化合物吉非替尼在表达BaF / 3的EGFR WT中显示出更强的细胞毒性作用。测定了所有合成化合物对吉非替尼不敏感的双突变体表达Del19 / T790M的Ba / F3和表达Ba / F3的L858R / T790M的抗增殖作用。化合物4d,6f,7e表现出显着的抑制作用(IC 50 与拉帕替尼(60.1 nM)相比 ,这些突变株中的Hs2 = 1.76–2.38μM,并且具有显着的Her2酶抑制(IC 50 = 19.2–40.6 nM)。证明了化合物6d,6f,7a,7b和8b的结合模式。此外,测试了对
