Quorum sensing is a regulatory system used by bacteria to control gene expression in response to increased cell density. This regulatory process manifests itself in a variety of phenotypes, including biofilm formation and virulence factor production. Coordinated gene expression is achieved through the production, release and detection of small diffusible signaling molecules called autoinducers. N-acylated homoserine lactones (AHLs) comprise a class of such autoinducers, each of which generally consists of a fatty acid coupled to a homoserine lactone (HSL). Modulation of bacterial quorum-sensing signaling systems to suppress pathogenesis represents a new approach to antimicrobial research for infectious diseases. AHLs differ in acyl length (C4-C18), C3 substitution (hydrogen, hydroxyl, or oxo group), and the presence or absence of one or more carbon-carbon double bonds in the fatty acid chain. These differences confer signaling specificity through the affinity of the LuxR family of transcriptional regulators. C11-HSL has a rare odd-numbered acyl carbon chain and may be a minor quorum-sensing signaling molecule in Pseudomonas aeruginosa strains.

Long-chain N-acyl homoserine lactones can be exported from cells by efflux pumps, or can be transported between communicating cells by extracellular outer membrane vesicles.

Veratryl alcohol (3,4-Dimethoxybenzyl alcohol) is a secondary metabolite of lignin-degrading fungi, commonly used as a substrate for lignin peroxidase (LiP) to measure lignin degradation activity. Veratryl alcohol protects LiP from inactivation by H2O2 and prevents the accumulation of LiP III compounds. Veratryl alcohol also acts as a stabilizer for manganese-dependent peroxidases (MnP). Veratryl alcohol is a quorum-sensing inhibitor (QSI) and exhibits antibacterial efficacy .

Quorum sensing is a regulatory system used by bacteria to control gene expression in response to increased cell density. This regulatory process manifests itself in a variety of phenotypes, including biofilm formation and virulence factor production. Coordinated gene expression is achieved through the production, release and detection of small diffusible signaling molecules called autoinducers. N-acylated homoserine lactones (AHLs) comprise a class of such autoinducers, each of which generally consists of a fatty acid coupled to a homoserine lactone (HSL). Modulation of bacterial quorum-sensing signaling systems to suppress pathogenesis represents a new approach to antimicrobial research for infectious diseases. AHLs differ in acyl length (C4-C18), C3 substitution (hydrogen, hydroxyl, or oxo group), and the presence or absence of one or more carbon-carbon double bonds in the fatty acid chain. These differences confer signaling specificity through the affinity of the LuxR family of transcriptional regulators. C9-HSL is a rare odd-numbered acyl carbon chain produced by wild-type Erwinia carotovora strain SCC 3193 grown in nutrient-rich Luria-Bertani broth (LB) medium.

Quorum sensing is a regulatory system used by bacteria to control gene expression in response to increased cell density. The control of bacterial infection by quenching the quorum sensing system of bacteria is a promising research area. The expression of specific target genes, such as transcriptional regulators belonging to the LuxIR protein family, is coordinated by the synthesis of diffusible acyl homoserine lactone (AHL) molecules. N-butyryl-L-Homocysteine thio-lactone is an analog of N-butyryl-L-homoserine lactone, a small, diffusible signaling molecule involved in quorum sensing, thereby controlling gene expression and cellular metabolism . N-butyryl-L-homocysteine thiolactone induces violacein expression in Viola viola mutants that normally fail to produce AHL.

C18-HSL, one of four lipophilic long acyl side chain AHLs produced by the LuxI AHL synthase homolog SinI, is involved in quorum-sensing signaling in strains of Rhizobium meliloti (a nitrogen-fixing bacterial symbiont of the legume M. sativa) . C18-HSL and other hydrophobic AHLs tend to localize in the relatively lipophilic environment of bacterial cells and cannot diffuse freely across the cell membrane. Long-chain N-acyl homoserine lactones can be exported from cells by efflux pumps, or can be transported between communicating cells by extracellular outer membrane vesicles.
