Alternative structural projections:


8- (4- Chlorophenylthio)- 2'- O- methylguanosine- 3', 5'- cyclic monophosphate ( 8-pCPT-2'-O-Me-cGMP ), sodium salt
Epac-negative control
Cat. No.: C 048
CAS No.: [625112-42-7]
Shipping: ambient
Product Name Price (net) Qty
Cat. No.: C 048-05
Unit: 5 µmol / ~2.6 mg
For other salt forms please inquire. The membrane-permeant 8-pCPT-2'-O-Me-cGMP neither activates protein kinase G nor Epac and can thus be used as a control. Characterized by high lipophilicity and membrane permeability, as well as increased PDE stability. Detailed technical information available.  Reference: Haag et al., Naunyn-Schmiedeberg´s Arch. Pharmacol., 378, 617 - 630 (2008).
