N-octanoyl-L-Homoserine lactone

Quorum sensing is a regulatory system used by bacteria for controlling gene expression in response to increasing cell density. Controlling bacterial infections by quenching their quorum sensing systems is a promising field of study. The expression of specific target genes, such as transcriptional regulators belonging to the LuxIR family of proteins, is coordinated by synthesis of diffusible acylhomoserine lactone (AHL) molecules. N-octanoyl-L-Homoserine lactone is a small diffusible signaling molecule involved in quorum sensing, thereby controlling gene expression and affecting cellular metabolism. The applications of this molecule include infection prevention and regulation of virulence in general and in cystic fibrosis.Formal Name: N-[(3S)-tetrahydro-2-oxo-3-furanyl]-octanamide.
