Application

8-(4-Chlorophenylthio)-guanosine 3′,5′-cyclic monophosphate sodium salt has been used to activate GMP-dependent protein kinase (PKG) in vascular smooth muscle cells (VSMCs).

Packaging

10, 50 mg in poly bottle

Biochem/physiol Actions

Membrane-permeable analog of cGMP that does not affect cGMP-regulated phosphodiesterase. A more potent cGMP analog than 8-Br-cGMP due to greater membrane permeability and a higher resistance to hydrolysis by phosphodiesterase. Used as a selective activator of cGMP dependent protein kinase (PKG). Found to be a very potent cyclic nucleotide-gated channel agonist.

Chronic hypoxia attenuates soluble guanylate cyclase-induced vasorelaxation in serotonin (5-HT)-contracted ovine carotid arteries. Because protein kinase G (PKG) mediates many effects of soluble guanylate cyclase activation through phosphorylation of multiple kinase targets in vascular smooth muscle, we tested the hypothesis...

In previous experiments, it was shown that migration of electropermeabilized human neutrophils induced by a combination of cGMP and cAMP markedly lower relative to that induced by cGMP or cAMP alone. However, when cGMP was replaced with 8-(para-chlorophenylthio-guanosine-3',5'-cyclic monophosphate (8-pCPT-cGMP)...

To investigate the mechanisms whereby guanosine 3',5'-cyclic monophosphate (cGMP) modulates microvessel permeability in vivo, we measured changes in microvessel hydraulic conductivity (Lp) and endothelial cytoplasmic Ca2+ concentration ([Ca2+]i) in response to the cGMP analogs 8-bromo-cGMP (8-BrcGMP) and 8-(p-chlorophenylthio)cGMP (8-pCPT-cGMP) in...

Cyclic nucleotides, including cyclic AMP (cAMP), cyclic GMP (cGMP) and cyclic ADP-ribose, have been extensively studied as second messengers of intracellular events initiated by activation of GPCRs. cAMP modifies cell function in all eukaryotic cells, principally through the activation of cAMP-dependent protein kinase (PKA), but also through cAMP-gated ion channels and guanine nucleotide exchange factors directly activated by cAMP.
