General description

A potent calmodulin antagonist that inhibits Ca2+/calmodulin-dependent protein kinase II (IC50 = 52 nM) and Ca2+/calmodulin-dependent phosphodiesterase (IC50 = 1.1 nM).
Potent calmodulin antagonist. Inhibits activation of calmodulin-dependent protein kinase II (IC50 = 52 nM). Interacts with the catalytic core of CaM kinase II as a pseudosubstrate.
