- Potent and selective inhibitor of PKA, with an IC50 of about 50 nM. Chijiwa, T., et al. "Inhibition of forskolin-induced neurite outgrowth and protein phosphorylation by a newly synthesized selective inhibitor of cyclic AMP-dependent protein kinase, N-[2-(p-bromocinnamylamino)ethyl]-5-isoquinolinesulfonamide (H-89), of PC12D pheochromocytoma cells." J. Biol. Chem. 265: 5267-5272 (1990).
- Also inhibits PKG and the µ isotype of PKC (at about 500 nM). In contrast, most other PKC isotypes are much more weakly inhibited, with IC50's in the 32 µM range.
