Description

General description

A potent, cell-permeable, reversible, and specific inhibitor of protein kinase A (IC₅₀ = 30 nM). Inhibition is competitive with respect to ATP. Shows only weak inhibitory activities against Ca²⁺-dependent protein kinase (CDPK), MLCK, PKC, and cyclic nucleotide-binding phosphatase.
