8-pCPT-2-O-Me-cAMP-AM

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 rate 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 the serum will cleave the acetoxymethyl ester and reduce cell permeability.
