生物活性

製品説明 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.
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].
