N-OCTANOYL-DL-HOMOSERINE LACTONE

Application test: Induces violacein expression in a Chromobacterium violaceum mutant usually not able to produce homoserine lactones.

N-Octanoyl-DL-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 are involved in quorum sensing, cell to cell communication among bacteria. Some AHLs are potent chemoattractants for human immune cells such as neutrophils.
