Covalent modification of disease-associated proteins with small molecules is a powerful approach for achieving an increased and sustained pharmacological effect. To reduce the potential risk of nonselective covalent modification, molecular design of covalent inhibitors is critically important. We report herein the development of a targeted covalent inhibitor for mutated epidermal growth factor receptor (EGFR) (L858R/T790M) using α-chlorofluoroacetamide (CFA) as the reactive group. The chemically tuned weak reactivity of CFA was suitable for the design of third-generation EGFR inhibitors that possess the pyrimidine scaffold. The structure-activity relationship study revealed that CFA inhibitor 18 (NSP-037) possessed higher inhibition selectivity to the mutated EGFR over wild-type EGFR when compared to clinically approved osimertinib. Mass-based chemical proteomics analyses further revealed that 18 displayed high covalent modification selectivity for the mutated EGFR in living cells. These findings highlight the utility of CFA as a warhead of targeted covalent inhibitors and the potential application of the CFA-pyrimidines for treatment of non-small-cell lung cancer.

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.
