8-cpt-cyclic amp

8-CPT-Cyclic AMP (8-CPT-cAMP) sodium is a selective activator of cyclic AMP-dependent protein kinase (PKA) and a potent inhibitor of cyclic GMP-specific phosphodiesterase (PDE VA) with an inhibitory concentration (IC50) of 0.9 μM. It also inhibits PDE III and PDE IV while significantly activating Epac, demonstrating diverse pharmacological activities [1] [2].

Rp-8-CPT-cAMP is a structural combination of the lipophilic and non-hydrolyzable cAMP analogs, 8-CPT-cyclic AMP and Rp-cyclic AMPS .[1] It functions as a site-selective inhibitor of protein kinase A (PKA) type I and II, with preference towards site A of type I and site B of type II.2 By occupying cAMP binding sites at the regulatory subunit of PKA, Rp-8-CPT-cAMP prevents the kinase holoenzyme from dissociative activation.[2],[3]
