Description générale

2-heptyl-3-hydroxy-4-quinolone can function as an intercellular signal.

Application

Quorum sensing is a signaling system used by bacteria to coordinate activity based upon their population density. The system involves the exchange of signaling molecules among bacteria via cell receptors. Heptyl-3-hydroxy-4(1H)-quinolone (PQS) is a quorum sensing-regulated virulence factor used to induce and study the regulation of virulence genes such as those involved in iron scavenging.

Pseudomonas aeruginosa releases a spectrum of well-regulated virulence factors, controlled by intercellular communication (quorum sensing) and mediated through the production of small diffusible quorum-sensing signal molecules (QSSM). We hypothesize that QSSM may in fact serve a dual purpose, also allowing

Pseudomonas aeruginosa produces 2-heptyl-3-hydroxy-4(1H)-quinolone (PQS), a quorum-sensing (QS) signal that regulates numerous virulence genes including those involved in iron scavenging. Biophysical analysis revealed that 2-alkyl-3-hydroxy-4-quinolones form complexes with iron(III) at physiological pH. The overall stability constant of 2-methyl-3-hydroxy-4-quinolone iron(III) complex

Numerous species of bacteria use an elegant regulatory mechanism known as quorum sensing to control the expression of specific genes in a cell-density dependent manner. In Gram-negative bacteria, quorum sensing systems function through a cell-to-cell signal molecule (autoinducer) that consists

Indole is an extracellular biofilm signal for Escherichia coli, and many bacterial oxygenases readily convert indole to various oxidized compounds including 7-hydroxyindole (7HI). Here we investigate the impact of indole and 7HI on Pseudomonas aeruginosa PAO1 virulence and quorum sensing

The emergence of antibiotic resistance has necessitated new therapeutic approaches for combating persistent bacterial infection. An alternative approach is regulation of bacterial virulence instead of growth suppression, which can readily lead to drug resistance. The virulence of the opportunistic human
