Descripción

Descripción general

A potent, cell-permeable, and reversible metabolically-stable cAMP antagonist that inhibits cAMP-dependent protein kinase and shows preference for PKA type I. More lipophilic than cAMP antagonist Rp-cAMPS (Cat. No. 116814).

Cell-permeable, potent, reversible, and metabolically stable antagonist of cAMP that is resistant to the action of mammalian cyclic nucleotide phosphodiesterases. Rp-8-Br-cAMPS is more lipophilic as compared to 8-Br-cAMP and Rp-cAMPS. In contrast to other common ATP-site inhibitors or to its parent compound Rp-cAMPS, Rp-8-Br-cAMPS discriminates between both isozymes of protein kinase A, preferring type I, thus providing additional selectivity. By occupying cAMP binding sites, prevents dissociation and activation of the kinase holoenzyme. λ = 264 nm (H₂O, pH 7.0); ε_max 17,000 M^-1cm^-1.

Note: 5 µmol = 2.23 mg.
