Solubility (25°C)* In vitro
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description H-89 is a potent and selective inhibitor of cyclic AMP-dependent protein kinase (protein kinase A) with IC50 values of 48 nM and has weak inhibition against PKG, PKC, Casein Kinase, and other kinases.
