n-3-oxo-tetradecanoyl-l-homoserine lactone

N-3-oxo-tetradecanoyl-L-Homoserine lactone (3-oxo-C14-HSL) is a small diffusible acylhomoserine lactone signaling molecule that functions in bacterial quorum sensing by coordinating LuxIR-family transcriptional regulators in response to cell density, appears later than shorter-chain AHLs during biofilm development, stimulates putisolvin production, and ultimately inhibits biofilm formation, N-3-oxo-tetradecanoyl-L-Homoserine lactone provides a critical molecular tool for studying bacterial communication, metabolism, and anti-virulence strategies.

N-3-oxo-hexadecanoyl-L-Homoserine lactone is an unusual, substituted, long-chain N-acyl-homoserine lactone (AHL) produced by some bacteria, including strains of Agrobacterium vitis and Pseudomonas. Like other AHLs, this C16-containing form is thought to be involved in quorum sensing. Substituted, long-chain AHLs, including N-3-oxo-tetradecanoyl-L-homoserine lactone , prime for systemic acquired resistance to pathogen attack in plants.
