The phenazine pyocyanin is a terminal signalling factor in the quorum sensing network of Pseudomonas aeruginosa [PDF]

, 2006
Certain members of the fluorescent pseudomonads produce and secrete phenazines. These heterocyclic, redox-active compounds are toxic to competing organisms, and the cause of these antibiotic effects has been the focus of intense research efforts.

Using model systems to unravel host–Pseudomonas aeruginosa interactions

Environmental Microbiology, Volume 25, Issue 10, Page 1765-1784, October 2023., 2023
Abstract Using model systems in infection biology has led to the discoveries of many pathogen‐encoded virulence factors and critical host immune factors to fight pathogenic infections. Studies of the remarkable Pseudomonas aeruginosa bacterium that infects and causes disease in hosts as divergent as humans and plants afford unique opportunities to shed

Chemical Modification of a Bacterial Siderophore by a Competitor in Dual‐Species Biofilms

Angewandte Chemie, Volume 135, Issue 29, July 17, 2023., 2023
Detailed investigation of the inter‐species chemical communication between the human pathogens P. aeruginosa and S. aureus revealed that S. aureus converts pyochelin, an important siderophore secreted by P. aeruginosa, to its less potent pyochelin methyl ester (PME). In addition, PME is sensed by P.

Redox Reactions of Phenazine Antibiotics with Ferric (Hydr)oxides and Molecular Oxygen [PDF]

, 2008
Phenazines are small redox-active molecules produced by a variety of bacteria. Beyond merely serving as antibiotics, recent studies suggest that phenazines play important physiological roles, including one in iron acquisition.

Diversity-Oriented Synthesis and Antibiofilm Evaluation of Furan-2-Carboxamides. [PDF]

ChemMedChem
Navigating through the chemical space of antibiofilm agents! Furan‐2‐carboxamides inhibit the production of this extracellular shield in Pseudomonas aeruginosa by modulating the linkers and substituents of the central core. The discovery offers a solution to the metabolically unstable antibiofilm agents based on furanones, leading to the design of more

Induction of systemic resistance to Botrytis cinerea in tomato by Pseudomonas aeruginosa 7NSK2 : role of salicylic acid, pyochelin, and pyocyanin [PDF]

, 2002
The rhizobacterium Pseudomonas aeruginosa 7NSK2 produces secondary metabolites such as pyochelin (Pch), its precursor salicylic acid (SA), and the phenazine compound pyocyanin. Both 7NSK2 and mutant KMPCH (Pch-negative, SA-positive) induced resistance to

Influence of fusaric acid on phenazine-1-carboxamide synthesis and gene expression of Pseudomonas chlororaphis strain PCL1391.

Microbiology, 2005
Production of the antifungal metabolite phenazine-1-carboxamide (PCN) byPseudomonas chlororaphisstrain PCL1391 is essential for the suppression of tomato foot and root rot caused by the soil-borne fungusF. oxysporumf. sp.radicis-lycopersici. The authors have shown previously that fusaric acid (FA), a phytotoxin produced byFusarium oxysporum, represses ...
