Pseudomonas aeruginosa FpvB Is a High-Affinity Transporter for Xenosiderophores Ferrichrome and Ferrioxamine B

open access: yesmBio, 2023
Iron is essential for many biological functions in bacteria, but its poor solubility is a limiting factor for growth. Bacteria produce siderophores, soluble natural products that bind iron with high affinity, to overcome this challenge.

Subcellular localization of the pyoverdine biogenesis machinery of Pseudomonas aeruginosa: a membrane-associated "siderosome" [PDF]

open access: yes, 2013
The peptidic siderophore pyoverdine is the primary iron uptake system of fluorescent pseudomonads, and a virulence factor in the opportunistic pathogen Pseudomonas aeruginosa.

Identification of Siderophores With Unexpected Antibacterial Properties From Actinoplanes teichomyceticus

open access: yesChemBioChem, Volume 27, Issue 15, 14 August 2026.
Here, we report isolation of acyl‐desferrioxamines from Actinoplanes teichomyceticus as a mixture of iron and aluminum complexes. The fraction containing these molecules exhibited antibacterial activity. We synthesized these molecules and found that they only exhibited antibacterial activity in the presence of aluminum.

Actinomycin Derivatives: Structural Diversification and Biological Activities

open access: yesChemMedChem, Volume 21, Issue 15, 14 August 2026.
Actinomycins are chromopeptide antibiotics exhibiting remarkable structural diversity and broad bioactivity. This review traces their development from naturally occurring D‐, X‐, A‐, G‐, Y‐, and Z‐type analogs to precursor‐directed, synthetic, and semisynthetic derivatives.

Synthesis of the Pyoverdin Chromophore by a Biomimetic Oxidative Cyclization [PDF]

open access: yesOrganic Letters, 2009
The fluorescent dihydropyrimido[1,2-a]quinoline chromophore of the pyoverdin siderophores has been synthesized by a biomimetic oxidative cyclization using an iodine(III) reagent, followed by elimination and dehydrogenation.

Mechanisms of Gui Zhi Fu Ling Formula in Liver Fibrosis: Metabolomics and Gut Microbiota Analysis

open access: yeseFood, Volume 7, Issue 3, June 2026.
Our study was based on the efficacy of the phenotype in an animal model and used multi‐omics to explore the mechanism of action of the compound. We found that Gui Zhi Fu Ling Formula may ameliorate hepatic fibrosis potentially associated with increased hepatic EPA and the expression of gut Pseudomonas.

Investigation of different methods in siderophore measurement in indigenous Fluorescent Pseudomonads [PDF]

open access: yesBiological Journal of Microorganism, 2017
Introduction:Fluorescent pseudomonads produced a variety of siderophores in which the pyoverdine type siderophore is the main one. These bacteria employ siderophores to increase availability of Iron for their own and plants consumption. Siderophores have
