The invention relates to a 2-arylamino pyridine, a pyridine or triazine derivative, a preparation method and a use thereof. The 2-arylamino pyridine, or the pyridine or triazine derivative can act on certain mutated epidermal growth factor receptors (EGFR) such as an L858R activating mutant, a delE746_A750 mutant, an Exonl9 deletion activating mutant, and a T790M drug-resistant mutant, so as to treat and prevent a disease and a condition. The 2-arylamino pyridine or the pyridine or triazine derivative can find applications in treating or prevention of cancers. The invention also relates to a pharmaceutical composition comprising the 2-arylamino pyridine or the pyridine or triazine derivative and applicable to prepare an intermediate of the 2-arylamino pyridine or the pyridine or triazine derivative, and relates to a method employing the 2-arylamino pyridine or the pyridine or triazine derivative to treat various types of EGFR-mediated diseases. |
