KN-62 is a potent and specific inhibitor of Ca2+/calmodulin-dependent protein kinase II (CaMKII) with Ki of 0.9 μM; also a non-competitive antagonist of the purinergic receptor P2RX7 (IC50 = 15 nM). It is selective for CaMKII relative to PKA, PKC and MLCK, but inhibits CaMKI and CaMKIV equally well, The Ki value of KN-62 for CaMK V is 0.8 μM.

(F) HEK239 cells were transfected with Flag-Cyclin D1 and Cyclin D1 siRNAs for 12 h, then cells were subjected to immunoblot detection. (G) DIV7 cortical neurons were treated with 10 μM KN62 or 15 μM Ntide and transfected with or without Cyclin D1 siRNAs for 24 h (Left panel), then apoptosis was determined.

KN-62 suppresses the A23187-induced autophosphorylation of Ca2+/CaM kinase in PC12 D cells.  KN-62 (10 μM) inhibits carbachol and potassium-stimulated insulin secretion from rat pancreatic islets.  KN-62 also inhibits growth of K562 cells and blocks cell cycle progression. 
|In vivo||KN-62 inhibits seizure-induced expression of brain-derived neurotrophic factor mRNA in adult rat brain. |
Kinase assay:Total kinase activity of CaMKII, determined in a standard 2 min assay (100 μL), contained 35 mM HEPES, 10 mM MgCl2, 1 mM CaCl2, 10 μg of chicken gizzard myosin 20-kD light chain, 0.1 μM calmodulin, and 10 μM [γ-33]ATP at 30 °C. The kinase reaction is halted by adding 1 mL of 10% trichloroacetic acid.

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
