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.

Development of powerful fluorescence imaging probes and techniques sets the basis for the spatiotemporal tracking of cells at different physiological and pathological stages. While current imaging approaches rely on passive probe-analyte interactions, here we develop photochromic fluorescent glycoprobes capable of...
