repressed H1975 cell replication harboring EGFRT790M mutations at a concentration of 0.037 μM. Inhibitor 10c demonstrated high selectivity (SI = 631.9) for T790M-containing EGFR mutants over wild type EGFR, suggesting that it will cause less side effects. Moreover, this compound also shows promising antitumor efficacy in a murine EGFRT790M/L858R-driven H1975 xenograft model without affecting body weight

生物组成,可用于提高耐
吉非替尼的非小细胞肺癌(NSCLC)治疗的活性和选择性。这导致了
抑制剂10c的鉴定,该
抑制剂对
EGFRT790M / L858R激酶表现出高活性(IC50 = 0.71 nM),并以0.037μM的浓度抑制了带有
EGFRT790M突变的H1975细胞复制。与野生型
EGFR相比,
抑制剂10c对含T790M的
EGFR突变体表现出较高的选择性(SI = 631.9),这表明它将引起较少的副作用。此外,该化合物在鼠
EGFRT790M / L858R驱动的H1975异种移植模型中也显示出有希望的抗肿瘤功效,而不会影响体重。
