n-hexanoyl-l-homoserine lactone

N-hexanoyl-L-Homoserine lactone (C6-HSL) 是一种可扩散信号分子，参与控制基因表达、影响细胞代谢和群体感应。

N-3-oxo-pentanoyl-L-Homoserine lactone is a chain-shortened derivative of the bacterial quorum sensing signaling molecule N-3-oxo-octanoyl-L-homoserine lactone .1It inhibits binding of the autoinducer N-3-oxo-hexanoyl homoserine lactone toE. colicontaining the transcription factor LuxR when used at a concentration of 230 nM.2It acts as an autoinducer to activate theV. fischeriluminescence system inE. coliwhen used at concentrations ranging from 20 to 200 nM. 1.Chhabra, S.R., Stead, P., Bainton, N.J., et al.Autoregulation of carbapenem biosynthesis in Erwinia carotovora by analogues of N-(3-oxohexanoyl)-L-homoserine lactoneJ.
