l-homoserine lactone

N-(3-Oxodecanoyl)-L-homoserine lactone (3-Oxo-C10-HSL) functions as a bacterial quorum-sensing signal autoinducer [1].

L-Homoserine ((S)-(-)-2-AMINO-4-HYDROXYBUTYRIC ACID) is a more reactive variant of the amino acid serine. In this variant, the hydroxyl side chain contains an additional CH2 group which brings the hydroxyl group closer to its own carboxyl group, allowing it to chemically react to form a five-membered ring. This occurs at the point that amino acids normally join to their neighbours in a peptide bond. L-Homoserine is therefore unsuitable for forming proteins and has been eliminated from the repertoire of amino acids used by living things. L-Homoserine is the final product on the C-terminal end of the N-terminal fragment following a cyanogen bromide cleavage.

3-Oxo-C16:1-HSL (3oxoC16:1Δ11cis(L)HSL) is an N-acyl-homoserine lactone from Pseudomonas aeruginosa that inhibits the pathogenic strains of Aspergillus vinelandii from causing crown galls on grapes, and can be used in biosensor research.

L-Gulono-1,4-lactone is a substrate of L-gulono-1,4-lactone oxidoreductase, which catalyzes the last step of the biosynthesis of L-ascorbic (Vitamin) C.

N-(3-Oxooctanoyl)-DL-homoserine lactone with stereochemistry-dependent growth regulatory activity for roots .

N-hexanoyl-DL-Homoserine lactone (C6-HSL), isolated from bivalve larval cultures, degrades bacteria and inhibits lesions induced by the phytopathogenic fungus B. cinerea.N-hexanoyl-DL-Homoserine lactone participates in the bacterial N-acyl-homoserine lactone (AHL) community-sensing (QS) system. N-hexanoyl-DL-Homoserine lactone is involved in the N-acyl-homoserine lactone (AHL) community sensing (QS) system between bacteria.

Aculene D, a fungal metabolite, exhibits quorum sensing (QS) inhibitory effects on Chromobacterium violaceum CV026, significantly diminishing violacein production in N-hexanoyl-l-homoserine lactone (C6-HSL) induced cultures of C. violaceum CV026 at sub-inhibitory concentrations [1].
