A cell-permeable, reversible, ATP-competitive, highly potent and selective inhibitor of epidermal growth factor receptor kinase (IC₅₀ = 3 nM) versus HER2-neu (IC₅₀ >100 µM) and platelet-derived growth factor receptor kinase (IC₅₀ >100 µM). Abolishes MAP kinase (ERK) activation induced by Angiotensin II (Cat. No. 05-23-0101). Also inhibits the activation of EGFR kinase and MAP kinase by 4-hydroxynonenal. Downregulates ARF1 activity and disperses Golgi structure. A 10 mM (1 mg/317 µl) solution of AG 1478 (Cat. No. 658548) in DMSO is also available.
A cell-permeable, reversible, ATP-competitive, highly potent and specific inhibitor of the epidermal growth factor (EGF) receptor tyrosine kinase (IC₅₀ = 3 nM). Much higher concentrations are required for inhibition of the kinase activity of the closely-related HER2 (neu/erb-B2) receptor (IC₅₀ >100 µM), the platelet-derived growth factor (PDGF) receptor (IC₅₀ >100 µM), and p210^Bcr-Abl (IC₅₀ >50 µM). Its mechanism of inhibition likely mimics that of the related compound, 4-(3-chloroanilino)quinazoline (CAQ), a competitive inhibitor with respect to ATP. Downregulates ARF1 activity and disperses Golgi structure.
