Biological Activity: | Rho-kinase (ROCK) inhibitor that displays high selectivity over other protein kinases (IC 50 values are 0.012, 0.180, 0.360, 0.745, 3.03, 5.68 and 28.3 μ M for ROCKII, CAMKII, PKG, Aurora A, PKA, PKC and MLCK respectively). Inhibits sulprostone-induced contractions in guinea pig aorta (IC 50 = 190 nM) and displays proerectile effects in rats. |
