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).
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
