  摘要：

  在本研究中，将一类新型的含有吡啶并[3,4- d ]嘧啶骨架和丙烯酰胺部分的化合物设计为不可逆的EGFR-TKI，以克服获得性EGFR-T790M的耐药性。最有前途的化合物25h抑制HCC827和H1975细胞生长，IC 50值分别为0.025μM和0.49μM。同时，25h表现出对EGFR L858R（IC 50  = 1.7 nM）和EGFR L858R / T790M（IC 50  = 23.3 nM）的有效抑制活性。25h可抑制HCC827和H1975细胞系中EGFR的磷酸化，并显着诱导HCC827细胞凋亡。此外，复合在建立的HCC827异种移植小鼠模型中，25h能在体内以50mg / kg的浓度显着抑制癌症的生长。这些结果表明2，4-二取代的6-（5-取代的吡啶-2-氨基）吡啶并[3，4- d ]嘧啶衍生物可以用作有效的EGFR抑制剂和有效的抗癌剂。
