resistance resulted from T790M/L858R double mutations. The most potent compound 23a showed excellent enzyme inhibitory activities and selectivity with nanomolar IC50 values for both the single T790M and double T790M/L858R mutant EGFRs, and was more than 8-fold selective for wild type EGFR. Compound 23a displayed strong antiproliferative activity against the H1975 non-small cell lung cancer (NSCLC) cells
根据市售的AZD9291与T790M的模型结合模式,设计并合成了一系列N -9-联苯-9 H-嘌呤-2-胺衍生物,目的是克服T790M / L858R双突变引起的耐药性。最有效的化合物23a对单T790M和双T790M / L858R突变EGFR均表现出优异的酶抑制活性和选择性,纳摩尔IC 50值为50,对野生型EGFR的选择性超过8倍。化合物23a展示了对带有T790M / L858R的H1975非小细胞肺癌(NSCLC)细胞的强抗增殖活性。而且它对A549细胞(WT EGFR和k-Ras突变)和HT-29细胞(非特殊基因类型)的效力较弱,显示出较高的安全指数。
