Azioni biochim/fisiol

N-Dodecanoyl-L-homoserine lactone is a member of N-acyl-homoserine lactone family. N-Acylhomoserine lactones (AHL) regulate gene expression in gram-negative bacteria, such as Echerichia and Salmonella, and are involved in quorum sensing, cell to cell communication among bacteria; for reviews see. Bacterial intercellular communication has become a target for the development of new anti-virulence drugs, and a research focus for the prevention of biofilm formation.

Quorum sensing (also called autoinduction) is a term that describes an environmental sensing system that allows bacteria to monitor their own population density. Autoinduction relies upon the interaction of a small diffusible signal molecule (the autoinducer) with a transcriptional activator

N-acylhomoserine lactones (AHLs) play an important role in regulating virulence factors in pathogenic bacteria. Recently, the enzymatic inactivation of AHLs, which can be used as antibacterial targets, has been identified in several soil bacteria. In this study, strain M664, identified

N-acyl L-homoserine lactones (AHLs) constitute a predominant class of quorum-sensing signaling molecules used by Gram-negative bacteria. Here, we report a sensitive and non-targeted HPLC-MS/MS method based on parallel reaction monitoring (PRM) to identify and quantitate known, unanticipated, and novel AHLs
