Inosine
Inosine, also known as hypoxanthosine or inotin, belongs to the class of organic compounds known as purine nucleosides. Purine nucleosides are compounds comprising a purine base attached to a ribosyl or deoxyribosyl moiety. Inosine is formed when hypoxanthine is attached to a ribose ring a beta-N9-glycosidic bond. Inosine is an intermediate in the degradation of purines and purine nucleosides to uric acid. Inosine is also an intermediate in the purine salvage pathway. Inosine occurs in the anticodon of certain transfer RNA molecules and is essential for proper translation of the genetic code in wobble base pairs. Inosine exists in all living species, ranging from bacteria to plants to humans. Inosine participates in a number of enzymatic reactions. In particular, inosine can be biosynthesized from inosinic acid through its interaction with the enzyme known as cytosolic purine 5-nucleotidase. In addition, inosine can be converted into hypoxanthine and ribose 1-phosphate through its interaction with the enzyme known as purine nucleoside phosphorylase. Altered levels of inosine have also been associated with purine nucleoside phosphorylase deficiency and xanthinuria type I, both of which are inborn errors of metabolism. Animal studies have suggested that inosine has neuroprotective properties. It has been proposed as a potential treatment for spinal cord injury (PMID: 16317421) and for administration after stroke, as inosine appears to induce axonal rewiring (PMID: 12084941). After ingestion, inosine is metabolized into uric acid, which has been found to be a natural antioxidant and peroxynitrite scavenger. As such, inosine may have potential benefits to patients with multiple sclerosis and Parkinson’s disease (PMID: 19425822). Inosine can also be produced by gut bacteria and appears to have a number of beneficial effects. Inosine, has been shown to activate peroxisome proliferator-activated receptor (PPAR)-gamma signaling in human colon epithelial cells. Furthermore, exogenous treatment of inosine has been found to protect against DSS-induced colitis in rodents by improving adenosine 2A receptor (A2AR)/PPAR-gamma-dependent mucosal barrier functions (PMID: 33820558). Microbiome-derived inosine has also been shown to modulate the response to checkpoint inhibitor immunotherapy in cancer models. In particular, decreased gut barrier function induced by immunotherapy increases systemic translocation of bacterially derived inosine and activates antitumor T cells. The effect of inosine is dependent on T cell expression of the adenosine A2A receptor and requires co-stimulation. Inosine appears to have other roles in non-mammalian system. For instance, it has been found to be an important feed stimulant by itself or in combination with certain amino acids in some species of farmed fish. For example, inosine and inosine-5-monophosphate have been reported as specific feeding stimulants for turbot fry, (Scophthalmus maximus) and Japanese amberjack. Inosine is a purine nucleoside in which hypoxanthine is attached to ribofuranose via a beta-N(9)-glycosidic bond. It has a role as a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It is a purines D-ribonucleoside and a member of inosines. It is functionally related to a hypoxanthine and a ribofuranose. A purine nucleoside that has hypoxanthine linked by the N9 nitrogen to the C1 carbon of ribose. It is an intermediate in the degradation of purines and purine nucleosides to uric acid and in pathways of purine salvage. It also occurs in the anticodon of certain transfer RNA molecules. (Dorland, 28th ed) Inosine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Inosine is a natural product found in Fritillaria thunbergii, Cichorium endivia, and other organisms with data available. Inosine is a metabolite found in or produced by Saccharomyces cerevisiae.

3-Deoxy-D-glycero-D-galacto-2-nonulosonic acid
3-Deoxy-D-glycero-D-galacto-2-nonulosonic acid (KDN) is a sialic acid (Sia) that is ubiquitously expressed in vertebrates during normal development and tumorigenesis. Its expression is thought to be regulated by multiple biosynthetic steps catalyzed by several enzymes, including CMP-Sia synthetase. (PMID 11479279) Sialic acids are frequently the terminal sugars on secreted and cell surface glycoproteins and glycolipids, and their presence can have considerable influence on the biological properties of a cell. For example, the temporal appearance and disappearance of polysialic polymers has been intimately linked with the proper development of neural tissues during embryogenesis. In pathogenic diseases, including meningitis and gastric inflammation, particular microbes recognize cell surface sialic acids when invading host cells. Sialic acid residues can also mask recognition sites such as galactose residues on glycoproteins to prevent their in vivo removal by asialoglycoprotein receptors. In certain cancers, changes in sialic acid amounts, types, and linkages have been associated with tumorogenesis and cancer metastasis.

Allopurinol riboside
Allopurinol is an analog of the natural purines in the body, and is quickly metabolized to oxypurines which is also a xanthine oxidase inhibitor. Allopurinol is a white, powdery drug used to treat gout. Its use in the United States was started in 1964. It is an isomer of hypoxanthine and inhibits the production of uric acid, the metabolite responsible for gout, by inhibiting the enzyme xanthine oxidase. The side effects of high levels of precursors are usually minor. A small percentage of people develop a rash and must discontinue this drug. The most serious adverse event is a hypersensitivity syndrome consisting of fever, skin rash, eosinophilia, hepatitis, and worsening renal function. In some cases, allopurinol hypersensitivity syndrome.
