Rho-Kinase (Rock2) is a serine/threonine kinase involved in the regulation of smooth muscle contraction and cytoskeletal reorganization of nonmuscle cells. Its inhibition is known to promote the smooth muscle relaxation. Thus, small-molecule inhibitors of Rho-Kinase may be effective probes for treatment of cerebral vasospasm and potentially effective for treatment of angina, hypertension, arteriosclerosis, and erectile dysfunction. Is this molecule inhibitor of Rock2? Rho-Kinase (Rock2) is a serine/threonine kinase involved in the regulation of smooth muscle contraction and cytoskeletal reorganization of nonmuscle cells. Its inhibition is known to promote the smooth muscle relaxation. Thus, small-molecule inhibitors of Rho-Kinase may be effective probes for treatment of cerebral vasospasm and potentially effective for treatment of angina, hypertension, arteriosclerosis, and erectile dysfunction. Can this molecule inhibite Rock2? Rho-Kinase (Rock2) is a serine/threonine kinase involved in the regulation of smooth muscle contraction and cytoskeletal reorganization of nonmuscle cells. Its inhibition is known to promote the smooth muscle relaxation. Thus, small-molecule inhibitors of Rho-Kinase may be effective probes for treatment of cerebral vasospasm and potentially effective for treatment of angina, hypertension, arteriosclerosis, and erectile dysfunction.
