Cat. No.: HY-W035904R
CAS No.: 539-80-0
Synonyms: Cycloheptatrienone (Standard)
Tropone (Standard) (Cycloheptatrienone (Standard)) is the analytical standard of Tropone (HY-W035904). This product is intended for research and analytical applications. Tropone (Cycloheptatrienone) is a non-benzenoid aromatic natural product that acts as a membrane reverse transporter and metal chelator. Tropone disrupts the proton motive force by affecting the transmembrane proton gradient and functions as a quorum sensing signal through LuxR-type transcriptional regulators. Tropone exhibits broad-spectrum antibiotic, anticancer, algicidal, and probiotic activities. As a virulence factor toxic to rice seedlings, Tropone promotes biofilm formation in Burkholderia plantarii and induces neurotoxicity involving mitochondrial and cytoskeletal damage, increased Ca 2+ influx, and oxidative stress. Tropone is used in the study of bacterial infections .

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. 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.

Synonyms: OHHL-d3; N-(3-Oxohexanoyl)homoserine lactone-d3
N-(3-Oxohexanoyl)-L-homoserine lactone-d3 (OHHL-d3) is the deuterated-labeled N-(3-Oxohexanoyl)-L-homoserine lactone (HY-W008806). N-(3-Oxohexanoyl)-L-homoserine lactone (OHHL; N-(3-Oxohexanoyl)homoserine lactone) is a specific agonist of LuxR-type transcription factor CarR with a Kd of 1.8 μM. N-(3-Oxohexanoyl)-L-homoserine lactone activates CarR by inducing protein multimerization, promoting its binding to target DNA sequences in the carR-carA intergenic region, thereby upregulating the transcription of carbapenem biosynthesis genes. N-(3-Oxohexanoyl)-L-homoserine lactone acts as a quorum sensing signal molecule, enabling bacteria to coordinate the production of carbapenem antibiotics in a cell density-dependent manner. N-(3-Oxohexanoyl)-L-homoserine lactone is used to study bacterial quorum sensing mechanisms, especially the secondary metabolism and virulence factor regulatory pathways of Erwinia carotovora and Yersinia enterocolitica .
