N-Acetylserotonin
N-Acetylserotonin (NAS), also known as normelatonin, is a naturally occurring chemical precursor and intermediate in the endogenous production of melatonin from serotonin. It also has biological activity in its own right, including acting as a melatonin receptor agonist, an agonist of the TrkB, and having antioxidant effects. N-Acetylserotonin is an intermediate in the metabolic pathway of melatonin and indoleamine in the pineal gland of mammalians. Serotonin-N-acetyltransferase (SNAT), which regulates the rate of melatonin biosynthesis in the pineal gland, catalyzes the acetylation of 5HT to N-acetylserotonin (NAS). A methyl group from S-adenosylmethionine is transferred to NAS by hydroxyindole-O-methyltransferase (HIOMT), and finally NAS is converted to 5-methoxy-N-acetyltryptamine, or melatonin. In most mammalian species the content of NAS (and melatonin) in the pineal gland shows clear circadian changes with the highest level occurring during the dark period. This elevation of the contents of NAS (and melatonin) in the dark period is due to the increase of SNAT activity and the elevation of SNAT gene expression. Experimental studies show that N-acetylserotonin possess free radical scavenging activity. Acute administration of irreversible and reversible selective MAO-A inhibitors and high doses (or chronic administration of low doses) of relatively selective MAO-B inhibitors (but not of highly selective MAO-B inhibitors) suppressed MAO-A activity and stimulated N-acetylation of pineal serotonin into N-acetylserotonin, the immediate precursor of melatonin. N-acetylserotonin increase after MAO-A inhibitors might mediate their antidepressive and antihypertensive effects. N-Acetylserotonin is the product of the O-demethylation of melatonin mediated by cytochrome P-450 isoforms: Cytochrome p450, subfamily IIc, polypeptide 19 (CYP2C19, a clinically important enzyme that metabolizes a wide variety of drugs), with a minor contribution from Cytochrome p450, subfamily I, polypeptide (2CYP1A2, involved in O-deethylation of phenacetin). (PMID 15616152, 11103901, 10721079, 10591054). N-Acetylserotonin acts as a potent antioxidant, NAS effectiveness as an anti-oxidant has been found to be different depending on the experimental model used, it has been described as being between 5 and 20 times more effect than melatonin at protecting against oxidant damage. NAS has been shown to protect against lipid peroxidation in microsomes and mitochondria. NAS has also been reported to lower resting levels of ROS in peripheral blood lymphocytes and to exhibit anti-oxidant effects against t-butylated hydroperoxide- and diamide-induced ROS. N-acetyl serotonin, also known as N-acetyl-5-hydroxytryptamine or N-(2-(5-hydroxy-1h-indol-3-yl)ethyl)acetamide, is a member of the class of compounds known as hydroxyindoles. Hydroxyindoles are organic compounds containing an indole moiety that carries a hydroxyl group. N-acetyl serotonin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). N-acetyl serotonin can be found in a number of food items such as tronchuda cabbage, winter savory, rambutan, and poppy, which makes N-acetyl serotonin a potential biomarker for the consumption of these food products. N-acetyl serotonin can be found primarily in blood and urine, as well as in human kidney and liver tissues. In humans, N-acetyl serotonin is involved in the tryptophan metabolism. Moreover, N-acetyl serotonin is found to be associated with schizophrenia. N-Acetyl-5-hydroxytryptamine is a Melatonin precursor, and that it can potently activate TrkB receptor.

3-Hydroxysebacic acid
3-Hydroxydecanedioic is a dicarboxylic acid that belongs to the class of compounds known hydroxy fatty acids. Hydroxy fatty acids are fatty acids that have hydroxyl functional groups attached to the principal chain. 3-Hydroxydecanedioic acid is found in most vertebrates. Urine from patients with ketoacidosis typically contains a number of aliphatic 3-hydroxy dicarboxylic acids, with the major compound being 3-hydroxydecanedioic acid (PMID: 7353273). The excretion of 3-hydroxydecanedioic acid is correlated with the excretion of hexanedioic acid, another metabolite frequently found in ketoacidosis (PMID: 5031780). It is thought that the 3-hydroxy dicarboxylic acids such as 3-hydroxydecanedioic acid are formed from fatty acids by a combination of omega-oxidation and incomplete beta-oxidation (PMID: 7353273). Marked elevation of urinary 3-hydroxydecanedioic acid has also been reported in a malnourished infant with glycogen storage disease (PMID: 8295400). Subsequent studies have shown that increased amounts of dicarboxylic acids, such as 3-hydroxydecanedioic acid, are typically excreted in human urine under conditions of medium-chain triglyceride (MCT) feeding, abnormal fatty acid oxidation (FAO) and fasting (PMID: 8596483). 3-Hydroxysebacic acid is a normal urinary 3-hydroxydicarboxylic acid metabolite and can be elevated in patients with peroxisomal disorders such as Zellweger syndrome. Marked elevation of urinary 3- Hydroxysebacic acid has also been described in a malnourished infant with glycogen storage disease, mimicking long-chain L-3-hydroxyacyl-CoA dehydrogenase deficiency (OMIM 300438, a defect in the beta-oxidation of fatty acids characterized by massive excretion of 3-hydroxydicarboxylic acids in the urine and accumulation of 3-hydroxy fatty acids in serum).

gamma-Glutamylalanine is a dipeptide composed of gamma-glutamate and alanine, and is a proteolytic breakdown product of larger proteins. It belongs to the family of N-acyl-alpha amino acids and derivatives. These are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. gamma-Glutamylalanine is a natural substrate of the enzyme (5-L-glutamyl)-L-amino acid 5-glutamyltransferase (cyclizing) (g-glutamylcyclotransferase, EC 2.3.2.2) in the glutathione metabolism pathway, which cleaves gamma-glutamylalanine to produce L-5-oxoproline. gamma-Glutamylcyclotransferase is widely distributed in both human and animal tissues where it catalyzes the scission of the y-peptide bonds of many different gamma-glutamyl-amino acids and gamma-glutamyl-gamma-glutamyl-amino acids. The latter are better substrates of the enzyme than the corresponding gamma-glutamyl-amino acids (PMID: 2570694, 2893631). 5-L-Glutamyl-L-alanine is a natural substrate of the enzyme 5-L-glutamyl)-L-amino acid 5-glutamyltransferase (cyclizing) (g-glutamylcyclotransferase, EC 2.3.2.2) in the glutathione metabolism pathway, which cleaves 5-L-Glutamyl-L-alanine, producing L-5-oxoproline. gamma-Glutamylcyclotransferase is widely distributed in both human and animal tissues where it catalyzes the scission of the y-peptide bonds of many different gamma-glutamyl-aminoacids and gamma-glutamyl-gamma-glutamyl-amino-acids.

Glutamylalanine
C8H14N2O5 (218.09026740000002)
Glutamylalanine is a naturally occurring dipeptide, composed of glutamate and alanine. Glutamylalanine is essential in the supply of glutamate to human erythrocytes. Human erythrocytes are essentially impermeable to glutamate and yet there is a continual requirement for the amino acid for glutathione synthesis. In addition, the intracellular glutamate concentration is approximately five times that of plasma. Glutamylalanine enters the human erythrocyte through saturable membrane-transport systems describable by Michaelis-Menten kinetics. The cytosolic red cell peptidases have a vast capacity to hydrolyse the dipeptide in a process also describable by simple Michaelis-Menten kinetics. The transport process is the rate-determining step in the pathway leading to the production of intracellular glutamate from extracellular glutamylalanine. Glutamylalanine is transported by the human oligopeptide transporter, hPepT1, situated in the small intestine, which is involved in the absorption of nutrient oligopeptides and transports numerous di- and tripeptides. This active transport is being tested for use as a strategy to increase the permeability across the intestine for larger biologically active molecules with low intestinal permeability, in a therapeutic attempt to transport dipeptide-coupled active drug substances via hPepT1 (PMID: 2860897, 11557350).

Glutamylalanine
C8H14N2O5 (218.09026740000002)
Glutamylalanine is a naturally occurring dipeptide. Glutamylalanine is essential in the supply of glutamate to human erythrocytes. Human erythrocytes are essentially impermeable to glutamate and yet there is a continual requirement for the amino acid for glutathione synthesis. In addition, the intracellular glutamate concentration is approximately five times that of plasma. Glutamylalanine enters the human erythrocyte through saturable membrane-transport systems describable by Michaelis- Menten kinetics. The cytosolic red cell peptidases have a vast capacity to hydrolyse the dipeptide in a process also describable by simple Michaelis-Menten kinetics. The transport process is the rate-determining step in the pathway leading to the production of intracellular glutamate from extracellular glutamylalanine. Glutamylalanine is transported by the human oligopeptide transporter, hPepT1, situated in the small intestine, which is involved in the absorption of nutrient oligopeptides and transports numerous di- and tripeptides. This active transport is being tested for use as a strategy to increase the permeability across the intestine for larger biologically active molecules with low intestinal permeability, in a therapeutic attempt to transport dipeptide-coupled active drug substances via hPepT1.
