Biological Activity

Description Hydroxyfasudil HCl, an active metabolite of fasudil hydrochloride, is a specific Rho-kinase(ROCK) inhibitor with IC50 values of 0.73 μM and 0.72 μM for ROCK1 and ROCK2, respectively.

0.72 μM 0.73 μM 37 μM
In vitro
In vitro Hydroxyfasudil prevents the downregulation of endothelial NO synthase (eNOS) under hypoxic conditions. In a concentration-dependent manner, hydroxyfasudil increases eNOS mRNA and protein expression, resulting in a 1.9- and 1.6-fold increase, respectively, at 10 μmol/L (P<0.05 for both). This correlates with a 1.5- and 2.3-fold increase in eNOS activity and NO production, respectively (P<0.05 for both)[1]. Hydroxyfasudil also inhibits various chemoattractant-induced migration of neutrophils. Hydroxyfasudil potently inhibits Rho-kinase (IC50, 0.9 ± 1.8 μM), while its inhibitory eff€ect is markedly (at least 50 ± 100 times) less for myosin light chain kinase (MLCK) or protein kinase C (PKC)[3].
Cell Research Cell lines Human vascular endothelial cells
Concentrations 0.1 to 100 μmol/L
Incubation Time 18 h
Method Human vascular endothelial cells are treated with increasing concentrations of hydroxyfasudil (0.1 to 100 μmol/L) and eNOS expression and activity are measured.
In Vivo
In vivo Intracoronary administration of hydroxyfasudil(HF) causes a significant coronary vasodilation of both small arteries and arterioles in a dose-dependent manner under control conditions with a resultant increase in CBF(coronary blood flow). Intracoronary hydroxyfasudil does not significantly alter mean aortic pressure or heart rate. Pretreatment with hydroxyfasudil markedly reduces the I/R-induced myocardial infarct size, and this beneficial effect of hydroxyfasudil is significantly attenuated by L-NMMA. NO may be involved in those cardiovascular protective effects of hydroxyfasudil. Hydroxyfasudil may also be effective for the treatment of pulmonary hypertension[2]. HF protects the myocardium subjected to pacing-induced ischaemia through the increase in the regional myocardial blood flow[3].

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
