ABSTRACT
Epidermal growth factor receptor (EGFR)-targeted therapy is used to treat EGFR mutation-induced non-small cell lung cancer (NSCLC). However, its efficacy does not last beyond a certain period due to the development of primary and secondary resistance. First and second-generation inhibitors (e.g., gefitinib, erlotinib, and afatinib) induce EGFR T790M mutations, while third-generation inhibitors (e.g., osimertinib) induce C797S as a major target resistance mutation. Therefore, the C797S mutation is being actively researched. In this study, we investigated the structure-activity relationship of several synthesized compounds as fourth-generation inhibitors against the C797S mutation. We identified a compound 13k that displayed nanomolar potency and high selectivity. Moreover, we used a triple mutant xenograft mouse model to evaluate the in vivo efficacy of 13k in inhibiting EGFR C797S, which demonstrated exceptional profiles and satisfactory EGFR C797S inhibition efficacy. Based on its excellent in vitro and in vivo profiles, compound 13k can be considered a promising candidate for treating EGFR C797S mutations.
