Epidermal growth factor receptor (EGFR) is one of the important and valuable drug targets. Overexpression of EGFR is associated with the development of many types of cancer. In this study, three PROTACs small molecules (16a–16c) were designed, synthesized and evaluated for their cytotoxicity against the growth in different NSCLC cell line and the degradation effect. The bioassay results indicated that 16c has a good inhibition in PC9 cells and H1975 cells, and the corresponding IC50 value was 0.413 μM and 0.657 μM, respectively. Western blotting results demonstrated that compound 16c could serve as an effective EGFRdel19-targeting degrader in PC9 cells.

Epidermal growth factor receptor (EGFR) inhibitors have been used clinically in the treatment of non-small-cell lung cancer (NSCLC) patients harboring sensitizing (or activating) mutations for a number of years. Despite encouraging clinical efficacy with these agents, in many patients resistance develops leading to disease progression. In most cases, this resistance is in the form of the T790M mutation. In addition, EGFR wild type receptor inhibition inherent with these agents can lead to dose limiting toxicities of rash and diarrhea. We describe herein the evolution of an early, mutant selective lead to the clinical candidate AZD9291, an irreversible inhibitor of both EGFR sensitizing (EGFRm+) and T790M resistance mutations with selectivity over the wild type form of the receptor. Following observations of significant tumor inhibition in preclinical models, the clinical candidate was administered clinically to patients with T790M positive EGFR-TKI resistant NSCLC and early efficacy has been observed, accompanied by an encouraging safety profile.

The present invention relates to certain 2-(2,4,5-substituted-anilino) pyrimidine compounds and pharmaceutically acceptable salts thereof which may be useful in the treatment or prevention of a disease or medical condition mediated through certain mutated forms of epidermal growth factor receptor (for example the L858R activating mutant, the Exonl9 deletion activating mutant and the T790M resistance mutant). Such compounds and salts thereof may be useful in the treatment or prevention of a number of different cancers. The invention also relates to pharmaceutical compositions comprising said compounds and salts thereof, especially useful polymorphic forms of these compounds and salts, intermediates useful in the manufacture of said compounds and to methods of treatment of diseases mediated by various different forms of EGFR using said compounds and salts thereof.
