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).

ChEBI: 8-(4-chlorophenylthio)-cGMP.Na is an organic sodium salt that is the monosodium salt of 8-(4-chlorophenylthio)-cGMP. It has a role as a protein kinase agonist. It contains an 8-(4-chlorophenylthio)-cGMP(1-).

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.
