Epidermal growth factor receptor (EGFR) inhibitors are provided. In particular, 4-substituted-2-(N-(5-substituted allyl amide)phenyl)amino)pyrimidine derivatives of formula (I), a preparation method and use thereof as an EGFR inhibitor are provided. The 4-substituted-2-(N-(5-substituted allyl amide)phenyl)amino)pyrimidine derivatives of formula (I) have inhibitory activity against the L858R EGFR mutant, the T790M EGFR mutant and the exon 19 deletion activating mutant, and can be used to treat diseases mediated alone or in part by EGFR mutant activity. The derivatives of formula (I) can be used to treat and/or prevent cancers, particularly non-small cell lung cancer.

The present invention provides compounds of Formula (I) or a subgeneric structure or species thereof or a pharmaceutically acceptable salt, ester, solvate, and/or prodrug thereof and methods and compositions for treating or ameliorating abnormal cell proliferative disorders, such as cancer, wherein A, R2, R3, R10, E1, E2, E3, Y, and Z are as defined herein.
Based upon the modeling binding mode of marketed AZD9291 with T790M, a series of 5,6-dihydro-4-Hpyrrolo[3,2,1-ij]quinoline derivatives were designed and synthesized with the purpose to overcome the drug resistance resulted from T790M/L858R double mutations. The most potent compound 8 showed excellent enzyme inhibitory activities and selectivity with sub nanomolar IC50 values for both the single L858R and double T790M/L858R mutant EGFRs, and was more than 8-fold selective for wild type EGFR. Compound 8 exhibited good microsomes stabilities and pharmacokinetic properties and lower binding affinity to hERG ion channel than AZD9291 and displayed strong antiproliferative activity against the H1975 non-small cell lung cancer (NSCLC) cells bearing T790M/L858R and in vivo anticancer efficacy in a human NSCLC (H1975) xenograft mouse model.
