N hexanoyl L Homoserine lactone

N-hexanoyl-L-Homoserine lactone (C6-HSL), a small diffusible signaling molecule, is involved in controlling gene expression, affecting cellular metabolism, and quorum sensing.

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.

Aculene D, a fungal metabolite, exhibits quorum sensing (QS) inhibitory effects on Chromobacterium violaceum CV026, significantly reducing violacein production in N-hexanoyl-l-homoserine lactone (C6-HSL) induced cultures of C. violaceum CV026 at sub-inhibitory concentrations [1].
