Biochem/physiol Actions
Irreversible pan-HER inhibitor, covalently targets EGFR/HER2/HER4, providing sustained signaling blockade and clinical benefit in HER2-positive breast cancer.
Neratinib (HKI-272), an oral, potent, irreversible pan-HER tyrosine kinase inhibitor, targets EGFR, HER2, and HER4 by covalently binding specific cysteine residues (Cys773/EGFR, Cys805/HER2) within the ATP-binding pocket. This mechanism provides prolonged target inhibition, effectively blocking HER phosphorylation (IC50 ~3-5 nM) and downstream MAPK/Akt signaling (IC50 ~2 nM). Consequently, it reduces cyclin D1/Rb phosphorylation (IC50 ~9 nM) and induces G1-S arrest and apoptosis in sensitive cell lines (e.g., BT474, SKBr3, A431) at low nM concentrations, underpinning its use against HER2-driven cancers.
