Biological Activity

Potent, cell permeable inhibitor of CaM kinase II (IC50 = 0.37 μM). Also a direct extracellular open channel blocker of voltage-gated potassium channels (IC50 = 307 nM for KV1.5) and abolishes IKr in ventricular myocytes (IC50 = 102.6 nM) independently of CaM kinase II inhibition. Water soluble form also available.
