Beschreibung

General description

A cell-permeable, reversible, and substrate competitive inhibitor of EGF receptor tyrosine kinase (IC₅₀ = 11 nM) and p60^c-src (IC₅₀ = 500 nM) with little effect on protein kinase A or protein kinase C (IC₅₀ >200 µM). Also inhibits NMDA-stimulated cGMP production (IC₅₀ = 30 nM). Exhibits anti-proliferative properties. Suppresses the angiogenic action of vascular endothelial growth factor (VEGF) in rats.

A cell-permeable, reversible, substrate competitive, and potent inhibitor of EGF receptor tyrosine kinase (IC₅₀ = 11 nM) and pp60^c-src (IC₅₀ = 500 nM) with little effect on protein kinase A or protein kinase C (IC₅₀ >200 µM). Also inhibits NMDA-stimulated cGMP production (IC₅₀ = 30 nM). Exhibits anti-proliferative properties. Suppresses the angiogenic action of vascular endothelial growth factor in rats.

Biochem/physiol Actions
