Rho-kinase, an effector of the small GTP-binding protein Rho, plays an important role in various cellular functions including vascular smooth muscle contraction, proliferation, and migration as well as inflammatory cell mobility.1 HA-1077 is a potent inhibitor of Rho-associated Kinase II (ROCK-II) and additionally inhibits Protein Kinase C-related Kinase 2 (PRK2), Mitogen- and Stress-Activated Protein Kinase (MSK1), and Mitogen Activated Protein Kinase-Activated Protein Kinase 1b (MAPKAP-K1b) with IC50 values of 1.9, 4, 5, and 15 µM, respectively.2 By inhibiting the activity of Rho-kinase, HA-1077 has been shown to reduce blood vessel constriction3, decrease pulmonary arterial pressure3, inhibit tumor angiogenesis4, and improve insulin signaling5 in various rodent models. While originally marketed for the prevention of cerebral vasospasm in patients with subarachnoid hemorrhage, oral formulations of HA-1077 are used for the treatment of a wide range of cardiovascular diseases including pulmonary arterial hypertension and stable angina.
