N-3-氧代十四烷基-7Z-烯酰基-L-高丝氨酸内酯

N-3-氧代十四烷基-7Z-烯酰基-L-高丝氨酸内酯（3-氧代-C14：1-Δ7cis-（L）-HSL）是单位置（碳原子的C7和C8之间的碳-碳双键） N-3-氧代酰基侧链），几何（顺式或Z几何）和立体异构体（在高丝氨酸内酯环的3位上的L或S绝对立体化学）通常可以称为3 -oxo-C14：1-HSL。3-oxo-C14：1-Δ7cis-（L）-HSL是一种细菌群体感应化合物，具有抗菌活性，抑制生物膜形成的能力并表现出免疫抑制活性。该化合物在结构上与其他3-氧代单不饱和（N-酰化高丝氨酸内酯）AHL，例如3

N-3-oxo-tetradec-7Z-enoyl-L-homoserine lactone (3-oxo-C14:1-Δ7cis-(L)-HSL) is a single, positional (carbon-carbon double bond between C7 and C8 of the N-3-oxo-acyl side chain), geometric (cis, or Z geometry), and stereoisomer (L, or S absolute stereochemistry at the 3-position of the homoserine lactone ring) of what may be generally referred to as a 3-oxo-C14:1-HSL. 3-oxo-C14:1-Δ7cis-(L)-HSL is a bacterial quorum sensing compound that possesses antimicrobial activity, the ability to inhibit biofilm formation, and exhibits immune suppressive activity. This compound is structurally related to other 3-oxo-monounsaturated (N-acylated homoserine lactones) AHLs such as 3-oxo-C16:1-Δ11cis-(L)-HSL.
