N decanoyl L Homoserine lactone

N-decanoyl-L-Homoserine lactone (C10-HSL) 是一种由克雷莫里色假单胞菌菌株 ND07产生的 N-acyl-homoserine lactone (AHL)。N-decanoyl-L-homoserine lactone 可抑制拟南芥的主根生长。N-decanoyl-L-homoserine lactone 处理可引起拟南芥根胞质游离 Ca2+ 和活性氧 (ROS) 浓度短暂和和立即升高，增加丝裂原激活蛋白激酶 6 (MPK6) 的活性，并促使一氧化氮 (NO) 的产生。

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