twenty-one compounds against EGFRwt were less than 50 nM, and those of six compounds were less than 10 nM. The IC50 values of eleven compounds against EGFRT790M/L858R were less than 100 nM. Among these, compound b1 displayed the most potent inhibitory activity against EGFRwt (IC50 = 2.0 nM) and EGFRT790M/L858R (IC50 = 6.9 nM). Compounds with excellent inhibitory activities against EGFRwt and EGFRT790M/L858R
设计,合成和评估了一系列新型的2,3-二氢-[1,4]二恶英[2,3- f ]喹唑啉衍生物,作为可逆的和非共价的表皮生长因子受体(EGFR)抑制剂。大多数化合物对EGFR wt表现出良好的效价,而某些对EGFR T790M / L858R突变体表现出中等至出色的效价。21种化合物对EGFR wt的半数最大抑制浓度(IC 50)值小于50 nM,而六种化合物的半数最大抑制浓度(IC 50)小于10 nM。十一种化合物对EGFR T790M / L858R的IC 50值小于100 nM。其中,化合物b1表现出对EGFR wt(IC 50 = 2.0 nM)和EGFR T790M / L858R(IC 50 = 6.9 nM)的最强抑制活性。对EGFR wt和EGFR T790M / L858R激酶具有出色抑制活性的化合物对H358和A549细胞表现出良好的抗增殖活性。进行了对接研究,将化合
