  • Patent number: 10428081
    Abstract: Epidermal growth factor receptor (EGFR) inhibitors are provided. In particular, 4-substituted-2-(N-(5-substituted ally 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 ally 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.
