8-pCPT-2-O-Me-cAMP-AM | Epac activator

8-pCPT-2-O-Me-cAMP-AM (1152197-23-3) is a potent, cell-permeable Epac (exchange protein directly activated by cAMP) activator.1 Induces RAP1 activation and insulin secretion in pancreatic beta cell lines.2-5 Induces vascular relaxation in rat mesenteric artery.6 The acetoxymethyl ester confers increased cell-permeability and is cleaved by endogenous esterases to yield the active compound, 8-pCPT-2'-O-Me-cAMP. Addition to cell cultures should be done in serum-free media as esterases in serum will cleave the acetoxymethyl ester and reduce cell permeability.
