H-1152二盐酸盐

ROCK Inhibitor. A cell-permeable isoquinolinesulfonamide compound that acts as a highly specific, potent, and ATP-competitive inhibitor of G-protein Rho-associated kinase (ROCK: Ki=1.6nM). Exhibits a much weaker affinity for other serine/threonine kinases (Ki=630nM for PKA 9.27 mMfor PKC, and 10.1mM for MLCK). Shown to selectively block lysophosphatidic acid-induced, but not PDBu-induced, phosphorylation of myristoylated alanine-rich C kinase substrate MARCKS (IC50=2.5nM) in NT-2 cells.
