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.

8-pCPT-2-O-Me-cAMP-AM (cas# 1152197-23-3) is a useful research chemical.8-pCPT-2-O-Me-cAMP-AM was used in the study to discover potential insulin secretagogue properties of an acetoxymethyl that activates guanine nucleotide exchange factors.
