Description

General description

A potent, reversible, ATP-competitive, and selective inhibitor of the Src family of protein tyrosine kinases. Inhibits p56^lck (IC₅₀ = 4 nM), p59^fynT (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 µM), or ZAP-70 (IC₅₀ >100 µM). 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 µl) solution of PP2 (Cat. No. 529576) in DMSO also available.
