Synthesis, Cytotoxic Activity, Antiquorum Sensing Effect, Docking and Md Simulation of Novel 1,3‐Disubstituted 2‐Mercapto‐1H‐Benzo[D]Imidazolium Chlorides

Journal of Biochemical and Molecular Toxicology, Volume 39, Issue 4, April 2025.
A series of benzimidazolium chlorides and their 2‐mercapto were successfully synthesized and characterized. Cytotoxic activity assays revealed that certain synthesized compounds exhibited efficacy against cancer cell lines. To investigate the possible mechanism underlying their cytotoxic effects, the binding interactions of the three most active ...

Quorum Sensing and Expression of Virulence in Pectobacteria

Sensors, 2012
Quorum sensing (QS) is a population density-dependent regulatory mechanism in which gene expression is coupled to the accumulation of a chemical signaling molecule. QS systems are widespread among the plant soft-rotting bacteria.

AhaP, A Quorum Quenching Acylase from Psychrobacter sp. M9-54-1 That Attenuates Pseudomonas aeruginosa and Vibrio coralliilyticus Virulence

Marine Drugs, 2021
Although Psychrobacter strain M9-54-1 had been previously isolated from the microbiota of holothurians and shown to degrade quorum sensing (QS) signal molecules C6 and C10-homoserine lactone (HSL), little was known about the gene responsible for this ...

Complete Genome Sequence of Burkholderia sp. Strain GG4, a Betaproteobacterium That Reduces 3-Oxo- N -Acylhomoserine Lactones and Produces Different N -Acylhomoserine Lactones [PDF]

Journal of Bacteriology, 2012
ABSTRACT Burkholderia sp. strain GG4, isolated from the ginger rhizosphere, possesses a unique N -acylhomoserine lactone (AHL)-modifying activity that reduces 3-oxo-AHLs to 3-hydroxy-AHLs. To the best of our knowledge, this is the first sequenced genome from a bacterium of the genus

PvdQ Quorum Quenching Acylase Attenuates Pseudomonas aeruginosa Virulence in a Mouse Model of Pulmonary Infection [PDF]

, 2018
Pseudomonas aeruginosa is the predominant pathogen in pulmonary infections associated with cystic fibrosis. Quorum sensing (QS) systems regulate the production of virulence factors and play an important role in the establishment of successful P ...

Biofilm formation in cardiovascular infection and bioengineering approaches for treatment and prevention

MedComm – Biomaterials and Applications, Volume 4, Issue 1, March 2025.
Biofilm‐related infections in cardiovascular system involve infective endocarditis, prosthetic heart valve endocarditis as well as cardiac device‐associated infections. There are still challenges remaining in the treatment of biofilm‐related infections in cardiovascular system.

Pandoraea sp. RB-44, A Novel Quorum Sensing Soil Bacterium

Sensors, 2013
Proteobacteria are known to communicate via signaling molecules and this process is known as quorum sensing. The most commonly studied quorum sensing molecules are N-acylhomoserine lactones (AHLs) that consists of a homoserine lactone moiety and an N ...

Quercetin Exhibits Broad‐Spectrum Antibiofilm and Antiquorum Sensing Activities Against Gram‐Negative Bacteria: In Vitro and In Silico Investigation Targeting Antimicrobial Therapy

Canadian Journal of Infectious Diseases and Medical Microbiology, Volume 2025, Issue 1, 2025.
Quercetin (QC), a flavonoid abundant in fruits and vegetables, has garnered attention for its potential therapeutic properties. In this study, we investigated the antibiofilm and antiquorum sensing (QS) activities of QC against Gram‐negative bacteria both in vitro and in silico.

Peptides as quorum sensing molecules : measurement techniques and obtained levels in vitro and in vivo [PDF]

, 2017
The expression of certain bacterial genes is regulated in a cell-density dependent way, a phenomenon called quorum sensing. Both Gram-negative and Gram-positive bacteria use this type of communication, though the signal molecules (auto-inducers) used by ...
