体外研究:

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. 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. H89 also has activity at some cellular receptors and ion channels, including Kv1.3 K+ channels,β1AR and β2AR.

体内研究: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. H-89 (0.5, 1, 5 mg/kg) significantly attenuates prominent behavioral signs of morphine withdrawal in morphine-dependent mice.
