N-(3-Oxotetradecanoyl)-DL-homoserine lactone（Cat No.:I045308）is a synthetic analog of a bacterial quorum-sensing signaling molecule belonging to the N-acyl homoserine lactone (AHL) family. It features a 14-carbon acyl chain with a 3-oxo substitution linked to a homoserine lactone ring. This compound is used in microbiology research to study quorum sensing, biofilm formation, and bacterial communication, particularly in Gram-negative bacteria. By mimicking natural AHL signals, it can activate or inhibit target LuxR-type receptors, enabling investigation of cell–cell signaling pathways, bacterial virulence regulation, and the development of quorum-sensing modulators for antimicrobial strategies.
