Description and Uses

KN-93 is a selective inhibitor of Ca²⁺/calmodulin-dependent kinase type II (CaMKII), competitively blocking CaM binding to the kinase (K_i = 370 nM). It does not affect the activities of PKA, PKC, MLCK, or Ca²⁺-phosphodiesterase. It inhibits histamine-induced aminopyrine uptake in parietal cells (IC₅₀ = 300 nM). More recently, KN-93 has been used to implicate roles for CaMKII in Ca²⁺-induced Ca²⁺ release in cardiac myocytes, constitutive phosphorylation of 5-lipoxygenase in 3T3 cells, and Ca²⁺-dependent activation of HIF-1α in colon cancer cells.

KN-93 has been used:

• as an inhibitor to block αCaMKII (Ca²⁺/calmodulin-dependent protein kinase IIα)
• as CaMKII inhibitor to pre-treat hippocampal slices
• to treat the cells, to alter the cytoskeleton (CSK) structure and function during the experiment
