Another ROCK inhibitor AR-13324 has recently passed the clinical trials whereas AMA0076, K115, PG324, Y39983 and RKI-983 are still under trials. Rho kinases (ROCKs) belong to the serine-threonine family, the inhibition of which affects the function of many downstream substrates. Rho-kinase inhibitors ( rho-associated protein kinase inhibitor or ROCK inhibitor) are a series of compounds that target rho kinase (ROCK) and inhibit the ROCK pathway. Rho-associated kinase (Rho-kinase/ROCK) was originally identified as an effector protein of the G protein Rho. Shown to be 5-fold less potent than Y-27632 (Cat. Unfortunately, kinase inhibitors designed to treat CVDs have suffered from numerous limitations such as poor selectivity, bad permeability and toxicity. Stock solutions are stable for up to 6 months at -20°C. A cell-permeable isoquinolinesulfonamide compound that acts as a highly specific, reversible, potent, and ATP-competitive inhibitor of G-protein Rho-associated kinase (ROCK; K i = 1.6 nM). The carboxy-terminal regions of ROCKs serve as an autoregulatory inhibitor of the amino-terminal kinase domain.9The interaction of the active GTP-bound form of Rho to ROCK's RBD increases ROCK activity through derepressionof the carboxyl-terminal RBD-PH domain on the amino-terminal kinase domain, leading to an active "open" kinase domain. Rho kinase (ROCK) inhibitors The Rho kinase (ROCK) isoforms, ROCK1 and ROCK2, were initially discovered as downstream targets of the small GTP-binding protein Rho.
