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.

Patients born with congenital heart defects frequently encounter arrhythmias due to defects in the ventricular conduction system (VCS) development. Although recent studies identified transcriptional networks essential for the heart development, there is scant information on the mechanisms regulating VCS development.
