Description

A potent, reversible, ATP-competitive, and selective inhibitor of the src family of tyrosine kinases that is similar to PP1. Selectively inhibits p56lck (IC50 = 4 nM), p59fynT (IC50 = 5 nM), Hck (IC50 = 5 nM), and Src (IC50 = 100 nM) compared to other tyrosine kinases, such as EGF-R (IC50 = 480 nM), JAK2 (IC50 >50 µ,M) or ZAP-70 (IC50 >100 µ,M). Also potently inhibits anti-CD3-stimulated tyrosine phosphorylation of human T cells (IC50 = 600 nM)., A potent, reversible, ATP-competitive, and selective inhibitor of the Src family of protein tyrosine kinases. Inhibits p56lck (IC50 = 4 nM), p59fynT (IC50 = 5 nM), Hck (IC50 = 5 nM), and Src (IC50 = 100 nM). Does not significantly affect the activity of EGFR kinase (IC50 = 480 nM), JAK2 (IC50 >50 µ,M), or ZAP-70 (IC50 >100 µ,M). Inhibits the activation of focal adhesion kinase and its phosphorylation at Tyr577. Also potently inhibits anti-CD3-stimulated tyrosine phosphorylation of human T cells (IC50 = 600 nM). A 10 mM (1 mg/331 µ,l) solution of PP2 (Cat. No. 529576) in DMSO also available.
