Description

General description

8-Bromoguanosine 3′,5′-cyclic monophosphate is a cell-permeable cGMP analog of cyclic guanosine 3′:5′-monophosphate (cGMP). It is a lipid-soluble analog used in cGMP based contraction studies in cardiomyocytes.

Application

8-Bromoguanosine 3′,5′-cyclic monophosphate sodium salt has been used:

• as a cyclic guanosine 3′:5′-monophosphate (cGMP) agonist in the collapse assay in retinal ganglion axons(10)
• as a component of reaction buffer in in vitro kinase activity assay of recombinant protein kinase (PKG)(11)
• as a cyclic nucleotide analog for the induction of cyclic nucleotide-gated channel (CNGA and CNGC) expression in human embryonic kidney cells(12)

Biochem/physiol Actions

8-Bromoguanosine 3′,5′-cyclic monophosphate has greater resistance to hydrolysis by phosphodiesterases than cGMP. Activates cGMP-dependent protein kinase. It slows or inhibits the intracellular calcium oscillations of tracheal smooth muscle cells in response to acetylcholine. 8-Bromoguanosine 3′,5′-cyclic monophosphate sodium salt mimics the effect of nitric oxide generating drugs. It modulates circadian rhythms and increases optic nerve impulses. In the eye 8-Bromoguanosine 3′,5′-cyclic monophosphate may favour transduction of non-R-type photoreceptors.
