General description

Phenazines are heterocyclic compounds produced as secondary metabolites by bacteria.


Phenazine methosulfate is used with ascorbic acid to determine nitric oxide reductase activity.
Phenazine methosulfate has been used:
  • as a component of succinate dehydrogenase enzyme substrate solution
  • to induce superoxide radical generation in red blood cell suspensions and to study its influence on RBC deformability
  • as a component of complex II histochemistry media

Biochem/physiol Actions

Phenazine m ethosulfate (PMS) acts as a good electron acceptor. PMS is reduced non-enzymatically by (nicotinamide adenine dinucleotide) NADH and (nicotinamide adenine dinucleotide phosphate) NADPH.
