  Because of their increased activity against activating mutants, first-generation epidermal growth factor receptor (EGFR) kinase inhibitors have had remarkable success in treating non-small-cell lung cancer (NSCLC) patients, but acquired resistance, through a secondary mutation of the gatekeeper residue, means that clinical responses only last for 8–14 months. Addressing this unmet medical need requires

  由于第一代表皮生长因子受体（EGFR）激酶抑制剂具有增强的针对激活突变体的活性，因此在治疗非小细胞肺癌（NSCLC）患者方面取得了显著成功，但通过关守的二次突变获得了耐药性残留，意味着临床反应仅持续8-14个月。为了满足这种未满足的医疗需求，需要能够同时靶向两种最常见的双突变体的药物：T790M / L858R（TMLR）和T790M / del（746-750）（TMdel）。在本文中，我们描述了如何使用侧重于结构指导的效价增加而不增加亲脂性或降低三维特征的策略优化非共价双突变体选择性先导化合物。经过连续几轮设计和合成，发现通过与酶的直接相互作用和/或对近端配体氧原子的影响，在4-羟基-和4-甲氧基哌啶基上进行顺式氟取代可提供协同，大量和特定的效能增强。氟羟基哌啶系列的进一步发展导致鉴定了一对非对映异构体，这些非对映异构体在体外显示出对T790M突变体比野生型EGFR（wtEGFR）具有
