A series of novel quinazoline derivatives bearing various C-6 benzamide substituents were synthesized and evaluated as EGFR inhibitors, and most showed significant inhibitory potency against EGFR kinase. In particular, compound 6g possessed potent inhibitory activity against EGFR wild-type (IC₅₀ = 5 nM), and strong antiproliferative activity against HCC827 and Ba/F3 (L858R) cell lines. Kinase profiling against a panel of 365 kinases showed that 6g was highly selective for EGFR. Furthermore, 6g showed desirable properties in assays of liver microsome metabolic stability and cytochromes P450 inhibition and preliminary pharmacokinetic study. The overall attractive profile of 6g made it an interesting compound for further development.

合成了一系列带有各种C-6苯甲酰胺取代基的新型喹唑啉衍生物，并将其作为EGFR抑制剂进行了评估，并且大多数都表现出对EGFR激酶的显着抑制作用。特别是，化合物6g对EGFR野生型（IC ₅₀  = 5 nM）具有有效的抑制活性，并且对HCC827和Ba / F3（L858R）细胞系具有很强的抗增殖活性。针对一组365种激酶的激酶谱分析表明6g对EGFR具有高度选择性。此外，6g在肝微粒体代谢稳定性和细胞色素P450抑制试验以及初步药代动力学研究中显示出理想的特性。6克的整体吸引力 使它成为进一步发展的有趣化合物。
