General description

A potent, cell-permeable, reversible, ATP-competitive and broad spectrum inhibitor of protein kinases. Inhibits CaM kinase (IC50 = 20 nM), myosin light chain kinase (IC50 = 1.3 nM), protein kinase A (IC50 = 7 nM), protein kinase C (IC50 = 0.7 nM), and protein kinase G (IC50 = 8.5 nM). Also inhibits platelet aggregation induced by collagen or ADP but has no effect on thrombin-induced platelet aggregation. Induces apoptosis in human malignant glioma cell lines. Arrests normal cells at the G1 checkpoint.

Inhibits protein kinase A (IC50 = 7 nM), CaM kinase (IC50 = 20 nM), myosin light chain kinase (IC50 = 1.3 nM), protein kinase C (IC50 = 700 pM), and protein kinase G (IC50 = 8.5 nM). Also inhibits platelet aggregation induced by collagen or ADP but has no effect on thrombin-induced platelet aggregation. Induces apoptosis in human malignant glioma cell lines. Arrests normal cells at the G1 checkpoint. A 1 mM (100 µg/214 µl) solution of Staurosporine (Cat. No. 569396) in DMSO is also available.
