Fasudil hydrochloride (HA-1077) is a potent inhibitor of ROCK1, PKA, PKC, and MLCK with Ki of 0.33 μM, 1.0 μM, 9.3 μM and 55 μM, respectively.

MLCK:55 μM(ki), PKA:1.0 μM(ki), PKC:9.3 μM(ki), ROCK1:0.33 μM(ki)

静脉注射0.01,0.03,0.1 和 0.3 mg/kg Fasudil剂量依赖性地降低MBP,提高HR,VBF,CBF,RBF和FBF.总剂量为1.0 ng/mL的 Fasudil提高心脏的输出量.通过冠状动脉内注射给实验狗30 μg Fasudil导致CBF增加约50％.口服Fasudil（剂量为100 mg/kg/天）显著降低用PLP p139-151免疫的SJL/J小鼠中EAE的发病率和平均最大临床评分.Fasudil抑制小鼠脾细胞对抗原的增殖反应.Fasudil处理显示心血管疾病的保护作用,并减少JNK的激活和减少AIF在缺血性损伤下的线粒体核移位.

Fasudil诱导肌动蛋白纤维解体,且抑制细胞迁移。Fasudil竞争性抑制Ca2+诱导的去极化兔主动脉收缩。Fasudil抑制对KCl,血清苯丙氨酸和前列腺素F2a的收缩反应。Fasudil抑制肝星状细胞的扩散,应力纤维的形成和α-SMA的表达,且抑制细胞生长,但不诱导细胞凋亡。Fasudil抑制LPA诱导的ERK1/2,JNK 和 p38 MAPK磷酸化。Fasudil还通过抑制5-羟色胺,去甲肾上腺素,组胺,血管紧张素和多巴胺诱导的螺旋条收缩来发挥血管舒张作用。

Cyclic AMP-dependent protein kinase activity is assayed in a reaction mixture containing, in a final volume of 0.2 mL, 50 mM Tris-HCl (pH 7.0), 10 mM magnesium acetate, 2 mM EGTA, 1 μM cyclic AMP or absence of cyclic AMP, 3.3 to 20 μM [r-32P] ATP (4×105 c.p.m.), 0.5 μg of the enzyme, 100 μg of histone H2B and compound. The mixture is incubated at 30°C for 5 min. The reaction is terminated by adding 1mL of ice-cold 20% trichloroacetic acid after adding 500 μg of bovine serum albumin as a carrier protein. The sample is centrifuged at 3000 r.p.m. for 15min, the pellet is resuspended in ice-cold 10% trichloro-acetic acid solution and the centrifugation-resuspension cycle is repeated three times. The final pellet is dissolved in 1 mL of 1 N NaOH and radioactivity is measured with a liquid scintillation counter.
