Biological Activity

Description 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.
Targets
CaMKⅠ [5] CaMKⅣ [6] P2RX7 [8] CaMKⅤ [7] CaMKII [1]
0.8 μM(Ki) 0.9 μM(Ki)
In vitro KN-62 suppresses the A23187-induced autophosphorylation of Ca2+/CaM kinase in PC12 D cells. [1] KN-62 (10 μM) inhibits carbachol and potassium-stimulated insulin secretion from rat pancreatic islets. [2] KN-62 also inhibits growth of K562 cells and blocks cell cycle progression. [3]
In vivo KN-62 inhibits seizure-induced expression of brain-derived neurotrophic factor mRNA in adult rat brain. [4]

Protocol (from reference)

Kinase Assay:

[1]
  • 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.

Cell Assay:

[3]
  • Cell lines

    K562 cells

  • Concentrations

    10 μM

  • Incubation Time

    48 hours

  • Method

    For cell growth analysis, K562 cells are plated in a 3-cm dish with 5 mL of culture medium containing various concentration of KN-62. After two days in these condition cell numbers are counted.
Animal Study:

[4]
  • Animal Models

    Sprague Dawley Rats

  • Dosages

    2 pmol

  • Administration

    i.c.v.
