General description
A solution of H-89, Dihydrochloride (Cat. No. 371963) in anhydrous DMSO. H-89 is a cell-permeable selective and potent inhibitor of protein kinase A (Ki = 48 nM). Inhibits other kinases at several fold higher concentrations: myosin light chain kinase (Ki = 28.3 µM), Ca2+/calmodulin-dependent protein kinase II (Ki = 29.7 µM), protein kinase C (Ki = 31.7 µM), casein kinase I (Ki = 38.3 µM), and Rho Kinase II (IC50 = 270 nM). May be used to discriminate between the effects of PKA and cAMP-regulated guanine-nucleotide-exchange factors (GEFs), such as GEFI or Epac (exchange protein directly activated by cAMP) and GEFII. Reported to induce neurite formation in NG 108-15 cells (~1 µM) by blocking the action of Rho kinase II.

Skeletal muscle generation of ammonia, an endogenous cytotoxin, is increased during exercise. Perturbations in ammonia metabolism consistently occur in chronic diseases, and may blunt beneficial skeletal muscle molecular responses and protein homeostasis with exercise. Phosphorylation of skeletal muscle proteins mediates
