n 3 oxo tetradecanoyl l homoserine lactone

N-3-oxo-tetradecanoyl-L-Homoserine lactone（3-oxo-C14-HSL）是一种小分子、可扩散的酰基高丝氨酸内酯信号分子，通过响应细胞密度协同调控 LuxIR 家族转录调节因子参与细菌群体感应。在生物膜形成过程中，该分子较短链 AHL 出现更晚，可刺激 putisolvin 生成并最终抑制生物膜形成。N-3-oxo-tetradecanoyl-L-Homoserine lactone 为研究细菌通讯、代谢及抗毒力策略提供了重要的分子工具。

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.
