8- (4- Chlorophenylthio)- ß- phenyl- 1, N²- ethenoguanosine- 3', 5'- cyclic monophosphorothioate, Sp- isomer ( Sp-8-pCPT-PET-cGMPS ), sodium salt
Highly membrane-permeant, PDE-resistant PKG agonist
Cat. No.: C 047
CAS No.: [1262749-63-2]
Shipping: ambient
Product Name Price (net) Qty
Cat. No.: C 047-01
Unit: 1 µmol / ~0.6 mg
For other salt forms please inquire. Membrane-permeant activator of cyclic GMP-dependent protein kinase, but most probably inhibitor of the retinal type cGMP-gated ion channel, thus suitable for distinction between kinase and ion channel mediated effects. Resistant against mammalian cyclic nucleotide-dependent phosphodiesterases. More lipophilic and membrane-permeant compared to Sp-8-Br-PET-cGMPS (Cat. No. P 008). Detailed technical information available. Reference: Jäger et al., Br. J. Pharmacol., 161, 1645 - 1660 (2010).
