Application

H-89 dihydrochloride hydrate has been used in the inhibition of protein kinase A in Leydig cells, primary calvarial osteoblasts (pOBs), rat granulosa cell line (LH-15 cells) and human umbilical vein endothelial cells (HUVECs).

Biochem/physiol Actions

H-89 dihydrochloride hydrate is a selective inhibitor of protein kinase A (PKA). It also inhibits potassium (K+) current in rat myocytes. It mediates Na+ transport by interacting with α subunits of epithelial Na+ channel (ENaC).
Selective, potent inhibitor of cAMP-dependent protein kinase.
