H 89 2HCl是一种有效的PKA抑制剂,Ki为48 nM,作用于PKA比作用于PKG选择性高10倍,比作用于PKC, MLCK,钙调蛋白激酶II和酪蛋白激I/II选择性高500倍。
应用:
H-89二盐酸盐水合物抑制蛋白激酶A,用于Leydig细胞、 原代颅骨成骨细胞(pOB)、大鼠颗粒细胞系(LH-15细胞)[3] 和人脐静脉内皮细胞(HUVEC)。
Information
H 89 2HCl is a potentPKAinhibitor withKiof 48 nM in a cell-free assay, 10-fold selective for PKA than PKG,500-fold greater selectivity than PKC, MLCK, calmodulin kinase II and casein kinase I/II. H 89 2HCl inducesautophagy.
In vitro
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.
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. H-89 (0.5, 1, 5 mg/kg) significantly attenuates prominent behavioral signs of morphine withdrawal in morphine-dependent mice.
