The epidermal growth factor receptor (EGFR) T790M mutant is found in approximately 50% of clinically acquired resistance to gefitinib among patients with non-small cell lung cancer (NSCLC). Here, a series of novel aminopyrimidines bearing a hydrazone moiety were identified as potent and selective EGFR inhibitors. Compounds 14a, 15g, and 15i potently inhibited all EGFR mutants including EGFR T790M/L858R
在非小细胞肺癌(NSCLC)患者中,约50%的临床获得的对吉非替尼的耐药性中发现了表皮生长因子受体(EGFR)T790M突变体。在这里,一系列带有bearing部分的新型氨基嘧啶被鉴定为有效的和选择性的EGFR抑制剂。化合物14a,15g和15i有效抑制所有EGFR突变体,包括EGFR T790M / L858R,EGFR T790M / delE746_A750和EGFR T790M,尽管它们对野生型(WT)EGFR的作用较弱。此外,这些化合物有效抑制了对吉非替尼耐药的H1975(EGFR T790M / L858R)细胞的增殖,但对A549(WT EGFR和k-Ras突变)和HT-29(非特殊基因类型)细胞的效力较弱,显示出高安全指数。因此,14a,15g和15i可能是有望克服由EGFR T790M突变体介导的耐药性的候选药物。
