Description

Pyoluteorin is a yellow-pigmented antibiotic produced by the bacterium Pseudomonas aeruginosa. It exhibits a broad spectrum of antimicrobial activity against Gram-positive bacteria, including Staphylococcus aureus, Bacillus subtilis, and Streptococcus pneumoniae. The molecule possesses a unique structure consisting of a diketopiperazine ring linked to a 2-amino-3-hydroxybenzoic acid moiety. Pyoluteorin's biosynthesis involves a complex enzymatic pathway that includes nonribosomal peptide synthesis and polyketide synthase activities. Research on pyoluteorin focuses on its potential as a therapeutic agent for treating bacterial infections, particularly those caused by multidrug-resistant pathogens. Its antimicrobial activity, coupled with its unique mode of action, makes it a promising candidate for the development of novel antibiotics. Additionally, studies have explored pyoluteorin's role in the interactions between Pseudomonas aeruginosa and other microorganisms in the environment.'

pyoluteorin : A member of the class of resorcinols that is resorcinol in which the hydrogen at position 2 is replaced by a 4,5-dichloro-1H-pyrrole-2-carbonyl group. It is a natural product found in Pseudomonas fluorescens which exhibits antibacterial properties and is a strong inducer of caspase-3-dependent apoptosis.

Research Excerpts

Overview

Pyoluteorin is an antifungal agent composed of a 4,5-dichlorinated pyrrole group linked to a resorcinol moiety. It is a chlorinated polyketide antibiotic secreted by the rhizosphere bacterium Pseudomonas fluorescens Pf-5.
