Biochem/physiol Actions

Ripasudil (K-115) is a more potent and selective rho-associated protein kinase (ROCK) inhibitor (IC50 = 51 nM/ROCK1, 19 nM/ROCK2, 2.1 μM/PKACα, 27 μM/PKC, and 0.37 μM/CaMKII?) than Y-27632 and HA-1077 (Fasudil). Ripasudil demonstrates in vivo efficacy in reducing intraocular pressure (IOP) by stimulating aqueous humour drainage through the trabecular meshwork.

Ripasudil hydrochloride hydrate (K-115), a specific Rho-associated coiled-coil containing protein kinase (ROCK) inhibitor, was the first ophthalmic solution developed for the treatment of glaucoma and ocular hypertension in Japan. Topical administration of K-115 decreased intraocular pressure (IOP) and increased outflow

1. We examined the metabolism of ripasudil (K-115), a selective and potent Rho-associated coiled coil-containing protein kinase (ROCK) inhibitor, by in vitro and in vivo studies. 2. First, we identified metabolites and metabolic enzymes involved in ripasudil metabolism. Species differences were observed
