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.

N-Acetyl-L-glutamic acid (Ac-L-Glu-OH) (NAcGlu) is an acetylated amino acid. NAcGlu is biosynthesized from glutamic acid and acetyl-CoA by the enzyme N-acetyl glutamate synthase (NAGS). NAcGlu activates carbamoyl phosphate synthetase in the urea cycle. A deficiency in N-acetyl glutamate synthase or a genetic mutation in the gene coding for the enzyme will lead to urea cycle failure in which ammonia is not converted to urea, but rather accumulated in the blood leading to the condition called Type I hyperammonemia.

In untreated hyperargininemic patients, it reaches its highest levels in cerebrospinal fluid. It has also been detected in apples and loquats, suggesting it could be a potential biomarker for consumption of these foods. Additionally, a low-arginine diet combined with sodium benzoate therapy leads to a marked decrease in plasma N-acetyl-L-arginine concentrations.

Quorum sensing is a regulatory system used by bacteria for controlling gene expression in response to increasing cell density. This regulatory process manifests itself with a variety of phenotypes including biofilm formation and virulence factor production. Coordinated gene expression is achieved by the production, release, and detection of small diffusible signal molecules called autoinducers. The N-acylated homoserine lactones (AHLs) comprise one such class of autoinducers, each of which generally consists of a fatty acid coupled with homoserine lactone (HSL). Regulation of bacterial quorum sensing signaling systems to inhibit pathogenesis represents a new approach to antimicrobial therapy in the treatment of infectious diseases. AHLs vary in acyl group length (C4-C18), in the substitution of C3 (hydrogen, hydroxyl, or oxo group), and in the presence or absence of one or more carbon-carbon double bonds in the fatty acid chain. These differences confer signal specificity through the affinity of transcriptional regulators of the LuxR family. C15-HSL is a product of Y. pseudituberculosis.

Quorum sensing is a regulatory system used by bacteria for controlling gene expression in response to increasing cell density. Controlling bacterial infections by quenching their quorum sensing systems is a promising field of study. The expression of specific target genes, such as transcriptional regulators belonging to the LuxIR family of proteins, is coordinated by the synthesis of diffusible acylhomoserine lactone (AHL) molecules. N-3-oxo-tetradecanoyl-L-homoserine lactone (3-oxo-C14-HSL) is a small diffusible signaling molecule involved in quorum sensing, thereby controlling gene expression and affecting cellular metabolism in bacteria.[1] [2] [3] It appears later than shorter acyl chain AHLs in developing biofilms [4] and, like other long chain 3-oxo-AHLs, stimulates the production of putisolvin, [5] which in turn, inhibits biofilm formation.

S-(N-Methylsulfinylbutylthiocarbamoyl)-L-cysteine (SFN-Cys) is an isothiocyanate derivative, functioning as an active metabolite of sulforaphane, a class I and II histone deacetylase (HDAC) inhibitor, and anticancer agent. This compound is generated from sulforaphane through intermediates - DL-sulforaphane glutathione and sulforaphane cysteinylglycine - via the mercapturic acid pathway enzymes. At a concentration of 20 µM, SFN-Cys diminishes invasion and migration of U87MG and U373 MG glioblastoma cells as observed in wound healing and chamber assays. Furthermore, at 45 µM, it significantly lowers the expression of α-tubulin, βIII-tubulin, stathmin 1, and X-linked inhibitor of apoptosis (XIAP), and also reduces cell density in paclitaxel-resistant A549 lung cancer cells (A549/T). Additionally, when used at 30 µM, SFN-Cys prompts apoptosis and cell cycle arrest at the G2/M phase in U87MG and U373 MG cells.
