Total Synthesis of Pyoverdin D
Organic Letters, 2013 Pyoverdin D is an important siderophore that is used by the human pathogen Pseudomonas aeruginosa to import iron and gain a competitive advantage. This unique partially cyclic octapeptide bears four nonproteinogenic amino acids, including (δ)N-formyl-(δ)N-hydroxy-l-ornithine, and a catechol containing chiral chromophore. Here, we report the first total

Advanced Technology for Detection of Wound Infection [PDF]
Int Wound JABSTRACT Early detection of infection in superficial skin wounds remains a critical determinant of healing outcomes, particularly in paediatric populations, where developmental and behavioural factors often limit clinical assessment. Traditional diagnostic approaches, including visual inspection and culture‐based microbiology, are constrained by ...

Siderophore activity of pyoverdin for Pseudomonas aeruginosa [PDF]
Infection and Immunity, 1985 Pseudomonas aeruginosa produces an extracellular compound with yellowish green fluorescence, called pyoverdin, which functions as a siderophore. The production of pyoverdin, formerly called fluorescein, is concomitant with the production of another siderophore, pyochelin. Pyoverdin is produced by P.

The Pyoverdins of Pseudomonas syringae and Pseudomonas cichorii
Zeitschrift für Naturforschung C, 2004 Abstract The structure elucidation of the cyclic (lactonic) forms of the pyoverdins with a succinamide side chain originally produced by the closely related species Pseudomonas syringae and P. cichorii is reported. Mass spectrometry and nuclear magnetic resonance analyses as well as the determination of the configuration of the amino ...

Pyoverdin is essential for virulence of Pseudomonas aeruginosa [PDF]
Infection and Immunity, 1996 The role of pyoverdin, the main siderophore in iron-gathering capacity produced by Pseudomonas aeruginosa, in bacterial growth in vivo is controversial, although iron is important for virulence. To determine the ability of pyoverdin to compete for iron with the human iron-binding protein transferrin, wild-type P. aeruginosa ATCC 15692 (PAO1 strain) and

Biogenesis of the Pyoverdin Chromophore
Zeitschrift für Naturforschung C, 1997 Abstract After growing Pseudomonas aeruginosa in the presence of 2 ,4-[4-15N]-diaminobutyric acid (Dab) its incorporation into the quinoline chromophore of the pyoverdin produced by this bacterium could be shown by mass and NMR-spectroscopic techniques.

Iron Acquisition from Fe-Pyoverdine by Arabidopsis thaliana
Molecular Plant-Microbe Interactions, 2007 Taking into account the strong iron competition in the rhizosphere and the high affinity of pyoverdines for Fe(III), these molecules are expected to interfere with the iron nutrition of plants, as they do with rhizospheric microbes.

Diastereomeric Pyoverdin-Chromium(III) Complexes
Zeitschrift für Naturforschung C, 2002 Coordination isomeric diastereomeric Cr3+ complexes of the pyoverdin of Pseudomonas aeruginosa ATCC 15692 could be separated by chromatography and characterized by spectroscopic methods.

Angewandte Chemie, Volume 138, Issue 17, 20 April 2026.Synopsis. The [68Ga]GaIII‐TREN‐CAM radiochelate selectively accumulates in Gram‐negative sites of infection and noninvasively monitors treatment response a siderophore antibiotic. ABSTRACT Positron emission tomography (PET) is an emerging tool under clinical investigation for the detection of bacterial infections.

Frontiers in Microbiology, 2014 Pseudomonas putida GB-1 is a Mn(II)-oxidizing bacterium that produces pyoverdine-type siderophores (PVDs), which facilitate the uptake of Fe(III) but also influence MnO2 formation.
