Inhibitors targeting the activating mutants of the epidermal growth factor receptor (EGFR) have found success in the treatment of EGFR mutant positive non-small-cell lung cancer. A secondary point mutation (T790M) in the inhibitor binding site has been linked to the acquired resistance against those first generation therapeutics. Herein, we describe the lead optimization of a series of reversible,
已经发现靶向表皮生长因子受体(EGFR)的活化突变体的抑制剂在治疗EGFR突变体阳性非小细胞肺癌中取得了成功。抑制剂结合位点的次级点突变(T790M)已与获得的对那些第一代治疗剂的抗性相关。本文中,我们描述了一系列可逆的泛突变(L858R,del 746-750, T790M / L858R和T790M / del 746-750)EGFR抑制剂的前导优化。通过使用非共价双突变体(T790M / L858R和T790M / del 746–750)选择性EGFR抑制剂(2)作为起点,可以对抗单个突变体(L858R和del 746–750))是通过一系列结构导向的修改引入的。通过许多合理的结构变化,进一步优化了先导分子的体外ADME-PK特性。所得的抑制剂(21)对EGFR的单突变体和双突变体均显示出优异的细胞活性,证明了体内靶标结合和适合进一步评估的ADME-PK特性。所描述的可逆非共价抑
