0.55mg/ml Taking the 1 mL working solution as an example, add 50 μL of 11 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

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.
Targets
ROCK2 [1]
(Cell-free assay)		 ROCK1 [1]

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].
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].
