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.

Maculosin is a host-specific phytotoxin for spotted knapweed from Alternaria alternata. Maculosin is a quorum-sensing molecule involved in cell-cell communication by Pseudomonas aeruginosa. Maculosin also acts as a signaling molecule regulating virulence gene expression in Lactobacillus reuteri. Maculosin shows antioxidant, anti-cancer and non-toxicity properties. Maculosin shows cytotoxic activity against the human liver cancer cell lines, with an IC50 of 48.90 µg/mL .

N-Octanoyl-DL-homoserine lactone is a member of N-acyl homoserine lactones (AHLs) family, also one of the signal molecule of quorum-sensing (QS) signals. N-Octanoyl-DL-homoserine lactone can regulate the production of siderophores and present positive correlation in Aeromonas sobria strain AS7. N-Octanoyl-DL-homoserine lactone can also regulate the secretion of proteases and stimulate the production of total volatile basic nitrogen (TVB-N) .
