8-CPT-2\'-O-Me-cAMP is a selective activator of Epac (Exchange Protein directly Activated by cAMP), the cAMP-sensitive guanine nucleotide-exchange factor (cAMP-GEF) for Rap1 and Rap2. It activates Epac1 with an EC50 of 2.2 µM, but not PKA (EC50 > 10 µM). This compound stimulates Epac-mediated Ca2+-mediated Ca2+ release in pancreatic b-cells in vitro. High lipophilicity and membrane permeability as well as increased PDE stability. 

Synonyms: Epac activator, 8-CPT-2\'-O-Me-cAMP sodium salt
