HKI-357 is an irreversible dual inhibitor of EGFR and ERBB2 (IC50s: 34 nM and 33 nM). HKI-357 suppresses EGFR autophosphorylation (at Y1068), and AKT and MAPK phosphorylation.

HKI-357 also is effective in suppressing EGFR autophosphorylation (measured at residue Y1068), and AKT and MAPK phosphorylation in parental NCI-H1650 cells harboring the delE746-A750 EGFR mutation.HKI-357 (0.01-10 μM) is effective in suppressing ligand-induced EGFR autophosphorylation and its downstream signaling, as determined by AKT and MAPK phosphorylation in NCI-H1975 cells.
