Rho-Kinase-IN-2 (Compound 23) is an orally active and selective inhibitor of RhoKinase (ROCK), which can penetrate the central nervous system (CNS). It exhibits a high affinity for ROCK2 with an inhibition constant (IC50) of 3 nM. This compound is of potential interest for further investigations in the field of Huntington's disease research [1].
Netarsudil, also known as AR-11324, is a Rho-associated proteinkinaseinhibitor. Netarsudil is potential useful for treating glaucoma and or reducing intraocular pressure. Netarsudil Increases Outflow Facility in Human Eyes Through Multiple Mechanisms. Netarsudil inhibited kinases ROCK1 and ROCK2 with a Ki of 1 nM each, disrupted actin stress fibers and focal adhesions in TM cells with IC50s of 79 and 16 nM, respectively, and blocked the profibrotic effects of TGF-β2 in HTM cells. Netarsudil produced large reductions in IOP in rabbits and monkeys that were sustained for at least 24 h after once daily dosing, with transient, mild hyperemia observed as the only adverse effect.
LX7101 is a potent inhibitor of both LIM kinase (LIMK) 1 and 2, and Rho-associated kinase 1 (ROCK1) and ROCK2, with IC50 values of 32, 4.3, 69, and 32 nM, respectively. It is selective, demonstrated by its lack of cross-reactivity in a panel of binding assays involving 78 receptors, transporters, and an additional 430 kinases, at a concentration of 10 μM. The topical administration of LX7101 (3 μl of a 1 mg ml solution) to the eye has been shown to reduce intraocular pressure in a dexamethasone-induced mouse model of glaucoma.
