Background:

H-1152 is a membrane-permeable and selective ROCK inhibitor, with a Ki value of 1.6 nM, and an IC50 value of 12 nM for ROCK2.

H-1152 is an inhibitor of Rho-kinase, with an IC50 of 12 nM for ROCK2. H-1152 (H-1152P) also shows less inhibitory activities against CaMKII, PKG, AuroraA, PKA, Src, PKC, MLCK, Abl, EGFR, MKK4, GSK3α, AMPK, and P38α, with IC50s of 0.180, 0.360, 0.745, 3.03, 3.06, 5.68, 28.3, 7.77, 50.0, 16.9, 60.7, 100, and 100 μM, respectively[1]. H-1152 potently inhibits Rho kinase, with a Ki of 1.6 nM, and slightly suppresses PKA, PKC and MLCK, with Kis of?0.63, 9.27, and 10.1 μM, respectively. H-1152 (0.1-10 &#181M) highly inhibits MARCKS phosphorylation, with an IC50 value of 2.5 &#181M in LPA-treated cells, but shows no such obvious effects in PDBu-treated cells[2]. H-1152 (0.5-10 μM) cuases no decreased neuronal survival. H-1152 (1, 5 or 10 μM) also exerts no alterations in the ratios of different neuronal morphologies. Furthermore, H-1152 (10 μM) increases neurite length in both BMP4 and LIF cultures[3].
