Biochem/physiol Actions

N-Heptanoyl-DL-homoserine lactone (C7HSL) is among a group of homoserine lactones that includes; N-octanoyl-homoserine lactone (N-C8-HSL), N-Decanoyl-DL-homoserine lactone (N-C10-HSL), N-(3-oxodecanoyl) homoserine-L-lactone (3-oxo-C10 HSL), N-(3-oxododecanoyl)homoserine-L-lactone (3-oxo-C12-HSL), N-(3-Oxotetradecanoyl)-L-homoserine lactone (3-oxo-C14-HSL, N-(3-hydroxydecanoyl)-L-homoserine lactone, and N-(3-hydroxyoctanoyl)-L-homoserine lactone involved in the processes of bacterial quorum sensing. These N-acyl-homoserine lactones are used to study the processes and mechanisms of bacterial quorum sensing.

N-Heptanoyl-DL-homoserine lactone is a member of N-acyl-homoserine lactone family. N-acylhomoserine lactones (AHL) regulate gene expression in gram-negative bacteria, such asEcherichia 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.
