Acetyl-N-formyl-5-methoxykynurenamine

N-[3-[2-(formylamino)-5-methoxyphenyl]-3-oxypropyl]-acetamide

C13H16N2O4 (264.111)


Acetyl-N-formyl-5-methoxykynurenamine (AFMK) results from the oxidative cleavage of the pyrrole ring during melatonin oxidation by myeloperoxidase (MPO), a superoxide anion (O)-dependent reaction. AFMK is also expected to be formed from oxidation catalyzed by the unspecific enzyme indoleamine-2,3-dioxygenase (IDO), found in a variety of cell types including monocyte/macrophage lineages. MPO- and IDO-catalyzed melatonin oxidation has the requirement of O in common, a species formed in large amounts in inflammatory conditions. The non-enzymatic formation of AFMK can also be expected by its direct reaction with highly reactive oxygen species, such as hydroxyl radical and singlet oxygen. Thus, we assume that AFMK is a product formed in a route of melatonin metabolism, especially active in inflammation. As AFMK is biologically more active on leukocytes than melatonin, the metabolizing of melatonin to AFMK at inflammatory sites possibly plays a role in immunomodulation. AFMK is found in the CSF of patients with meningitis, and in some samples at a remarkably high concentration, with AFMK found in some patients exceeding the concentration of melatonin normally found in serum.

Saccharopine

(2S)-2-{[(5S)-5-amino-5-carboxypentyl]amino}pentanedioic acid

C11H20N2O6 (276.1321)


Saccharopine is an intermediate in the degradation of lysine, formed by the condensation of lysine and alpha-ketoglutarate. The saccharopine pathway is the main route for lysine degradation in mammals, and its first two reactions are catalyzed by enzymatic activities known as lysine-oxoglutarate reductase (LOR) and saccharopine dehydrogenase (SDH), which reside on a single bifunctional polypeptide (LOR/SDH) (EC 1.5.1.8). The reactions involved with saccharopine dehydrogenases have very strict substrate specificity for L-lysine, 2-oxoglutarate, and NADPH. LOR/SDH has been detected in a number of mammalian tissues, mainly in the liver and kidney, contributing not only to the general nitrogen balance in the organism but also to the controlled conversion of lysine into ketone bodies. A tetrameric form has also been observed in human liver and placenta. LOR activity has also been detected in brain mitochondria during embryonic development, and this opens up the question of whether or not lysine degradation has any functional significance during brain development. As a result, there is now a new focus on the nutritional requirements for lysine in gestation and infancy. Finally, LOR and/or SDH deficiencies seem to be involved in a human autosomal genetic disorder known as familial hyperlysinemia, which is characterized by serious defects in the functioning of the nervous system and characterized by a deficiency in lysine-ketoglutarate reductase, saccharopine dehydrogenase, and saccharopine oxidoreductase activities. Saccharopinuria (high amounts of saccharopine in the urine) and saccharopinemia (an excess of saccharopine in the blood) are conditions present in some inherited disorders of lysine degradation (PMID: 463877, 10567240, 10772957, 4809305). If present in sufficiently high levels, saccharopine can act as an acidogen and a metabotoxin. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Saccharopine is an organic acid. Abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis. Acidosis typically occurs when arterial pH falls below 7.35. In infants with acidosis, the initial symptoms include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy). Many affected children with organic acidemias experience intellectual disability or delayed development. Amino acid from Saccharomyces cerevisiae and Neurospora crassaand is also found in mushrooms and seeds

6-Hydroxymelatonin

N-[2-(6-hydroxy-5-methoxy-1H-indol-3-yl)ethyl]acetamide

C13H16N2O3 (248.1161)


6-Hydroxymelatonin, also known as lopac-H-0627, belongs to the class of organic compounds known as hydroxyindoles. These are organic compounds containing an indole moiety that carries a hydroxyl group. 6-Hydroxymelatonin is considered to be a practically insoluble (in water) and relatively neutral molecule. 6-Hydroxymelatonin has been found in human liver and kidney tissues, and has also been detected in multiple biofluids, such as urine and blood. Within the cell, 6-hydroxymelatonin is primarily located in the cytoplasm. 6-Hydroxymelatonin is the main primary metabolite that can be biosynthesized from melatonin through its interaction with the enzyme cytochrome P450 (CYP) 1A2 (PMID: 11452239). In humans, 6-hydroxymelatonin is involved in the tryptophan metabolism pathway. Melatonin is a hormone that is metabolized by cytochrome P450 (CYP) 1A2 to its main primary metabolite 6-hydroxymelatonin. (PMID 11452239) [HMDB]. 6-Hydroxymelatonin is found in many foods, some of which are garden onion, millet, peppermint, and apricot.
