Chemical Name: 8-(4-Chlorophenylthio)-2'-O-methyladenosine-3',5'-cyclic monophosphate sodium salt

Biological Activity

Selective activator of Epac, the cAMP-sensitive guanine nucleotide-exchange factor for Rap1 and Rap2. Activates Epac1 (EC50 = 2.2 μM), but not PKA (EC50 > 10 μM). Stimulates Epac-mediated Ca2+-mediated Ca2+ release in pancreatic β-cells in vitro. Cell permeable analog (Cat. No. 4853) also available.

Licensing Information
