Hodoodo CAT#: H333023

CAS#: 915942-22-2 (maleate)

Description: Neratinib, also known as HKI-272 or PB272, is an orally available, irreversible inhibitor of the HER-2 receptor tyrosine kinase with potential antineoplastic activity. Neratinib binds to the HER-2 receptor irreversibly, thereby reducing autophosphorylation in cells, apparently by targeting a cysteine residue in the ATP-binding pocket of the receptor.
