EGFR-IN-176

EGFR-IN-176 is an orally active and ATP-competitive EGFR mutant inhibitor (particularly C797S-mediated EGFR triple mutant). EGFR-IN-176 effectively inhibits subsequent AKT signaling and induces apoptosis in Ba/F3 and PC-9 cells expressing EGFR^{19del/T790M/C797S} and EGFR^{L858R/T790M/C797S}. EGFR-IN-176 selectively inhibits EGFR signaling in cell lines harboring EGFR triple mutation and shows no inhibitory effect against A431 cells that express wild-type EGFR. EGFR-IN-176 can effectively inhibit the enzymatic activity of ALK (IC₅₀ < 0.5 nM). EGFR-IN-176 can be used for the study of non-small cell lung cancer (NSCLC).
