H89 2HCl is a potent PKA (cAMP-dependent) protein kinase A inhibitor with Ki of 48 nM, exhibits 10-fold selectivity over PKG, exhibits >500-fold selectivity over PKC, MLCK, calmodulin kinase II and casein kinase I/II. Pretreatment of the cells with H-89 (30 μM) 1 h before the addition of forskolin markedly inhibits the forskolin-induced protein phosphorylation in a dose-dependent manner. [1] H89 also inhibits several other kinases with IC50 of 80, 120, 135, 270, 2600 and 2800 nM for S6K1, MSK1, PKA, ROCKII, PKBα and MAPKAP-K1b, respectively. [2][3] H89 also has activity at some cellular receptors and ion channels, including Kv1.3 K+ channels,β1AR and β2AR. [4] |

| In vivo | H89 causes distinct modifications of protein phosphorylation, with the most robust changes in phosphorylation are fructose-1,6-biphosphatase, heterogeneous nuclear ribonucleoprotein (hnRNP), NSFL1 cofactor p47, all which have potentially regulatory connections to cAMP/PKA. [5] H-89 (0.5, 1, 5 mg/kg) significantly attenuates prominent behavioral signs of morphine withdrawal in morphine-dependent mice.[6] |
Protocol
| Kinase Assay:[1] |
- Collapse
PKA enzyme activity: cAMP-dependent protein kinase activity is assayed in a reaction mixture containing, in a final volume of 0.2 mL, 50 mM Tris-HC1 (pH 7.0), 10 mM magnesium acetate, 2 mM EGTA, 1 μM cAMP or absence of cAMP, 3.3-20 μM [γ-32P]ATP (4 × 105 cpm), 0.5 μg of the enzyme, 100 μg of histone H2B, and each compound, as indicated. |

Bio Calculators
Molarity Calculator
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).
Dilution Calculator
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.
