H-9 hydrochloride inhibits PKA (Ki=1.9 muM), PKC (Ki=18 muM cGKI (PKG) =0.87 muM MLCK=70 muM). It has shown to dramatically reduce the GABA response of GABAA currents in retinal rod bipolar cells as well as inhibit smooth muscle cell relaxation induced by cGRP. H-9 dihydrochloride has also been used for purification of protein kinases in ligand affinity chromatography.
