Application Notes
Hemipyocyanine (1-hydroxyphenazine) is a simple phenazine metabolite produced by several species of 
Pseudomonas and Streptomyces. Hemipyocyanine exhibits broad spectrum activity with weak antibacterial, 
antifungal and antiviral activity. In the search for novel actives, hemipyocyanine and related phenazines are 
important dereplication standards to eliminate leads due to high amounts of weakly potent actives. Hemipyocyanine 
plays an important role in the biocontrol of plant diseases by some Pseudomonas strains.
