General description

A cell-permeable, reversible, and substrate competitive inhibitor of EGF receptor tyrosine kinase (IC50 = 11 nM) and p60c-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 pp60c-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.

Long-term potentiation (LTP) in the hippocampus is thought to contribute to memory formation. In the Ca1 region, LTP requires the NMDA (N-methyl-D-aspartate) receptor-dependent influx of Ca2+ and activation of serine and threonine protein kinases. Because of the high amount of
