Allantoin is an imidazolidine-2,4-dione that is 5-aminohydantoin in which a carbamoyl group is attached to the exocyclic nitrogen. It has a role as a vulnerary, a human metabolite, a Saccharomyces cerevisiae metabolite and an Escherichia coli metabolite. It is a member of ureas and an imidazolidine-2,4-dione. It is functionally related to a hydantoin. It is a tautomer of a 1-(5-hydroxy-2-oxo-2,3-dihydroimidazol-4-yl)urea. Allantoin is a substance that is endogenous to the human body and also found as a normal component of human diets. In healthy human volunteers, the mean plasma concentration of allantoin is about 2-3 mg/l. During exercise, the plasma allantoin concentration rapidly increases about two fold and remains elevated. In human muscle, urate is oxidized to allantoin during such exercise. The concentration of allantoin in muscles increases from a resting value of about 5000 ug/kg to about 16000 ug/kg immediately after short-term exhaustive cycling exercise. More specifically, allantoin is a diureide of glyoxylic acid that is produced from uric acid. It is a major metabolic intermediate in most organisms. Allantoin is found in OTC cosmetic products and other commercial products such as oral hygiene products, in shampoos, lipsticks, anti-acne products, sun care products, and clarifying lotions. Allantoin has also demonstrated to ameliorate the wound healing process in some studies. Allantoin is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Allantoin is a natural product found in Aristolochia gigantea, Rhinacanthus, and other organisms with data available. Allantoin is a mineral with formula of C4H6N4O3. The corresponding IMA (International Mineralogical Association) number is IMA2020-004a. The IMA symbol is Aan. Allantoin is a diureide of glyoxylic acid with the chemical formula C4H6N4O3. It is also called 5-ureidohydantoin, glyoxyldiureide, and 5-ureidohydantoin. It is a product of oxidation of uric acid. It is a product of purine metabolism in most mammals except higher apes, and it is present in their urine. In humans, uric acid is excreted instead of allantoin. The presence of allantoin in the urine can be an indication of microbial overgrowth or it can be created via non-enzymatic means through high levels of reactive oxygen species. In this regard Allantoin is sometimes used as a marker of oxidative stress. Allantoin can be isolated from cow urine or as a botanical extract of the comfrey plant. It has long been used for its healing, soothing, and anti-irritating properties. Allantoin helps to heal wounds and skin irritations and stimulates the growth of healthy tissue. Allantoin can be found in anti-acne products, sun care products, and clarifying lotions because of its ability to help heal minor wounds and promote healthy skin.

It is also called 5-ureidohydantoin or glyoxyldiureide. It is a diureide of glyoxylic acid. Named after the allantois, an amniote embryonic excretory organ in which it concentrates during development in most mammals except humans and higher apes, it is a product of oxidation of uric acid by purine catabolism. After birth, it is the predominant means by which nitrogenous waste is excreted in the urine of these animals. In humans and higher apes, the metabolic pathway for conversion of uric acid to allantoin is not present, so the former is excreted. Recombinant rasburicase is sometimes used as a drug to catalyze this metabolic conversion in patients. In fish, allantoin is broken down further (into ammonia) before excretion.

1,4-Naphthoquinone

1,4-Dihydro-1,4-diketonaphthalene

1,4-naphtoquinone, also known as 1,4-naphthalenedione or 1,4-dihydro-1,4-diketonaphthalene, is a member of the class of compounds known as naphthoquinones. Naphthoquinones are compounds containing a naphthohydroquinone moiety, which consists of a benzene ring linearly fused to a bezene-1,4-dione (quinone). 1,4-naphtoquinone is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 1,4-naphtoquinone can be synthesized from naphthalene. 1,4-naphtoquinone is also a parent compound for other transformation products, including but not limited to, 2,3-dimethoxynaphthalene-1,4-dione, alisiaquinone A, and 1,4-naphthoquinone-2-carboxylic acid. 1,4-naphtoquinone can be found in liquor, which makes 1,4-naphtoquinone a potential biomarker for the consumption of this food product. 1,4-naphtoquinone is a non-carcinogenic (not listed by IARC) potentially toxic compound. CONFIDENCE standard compound; INTERNAL_ID 18 1,4-Naphthoquinone is a potential pharmacophore for inhibition of both MAO (monoamine oxidase) and DNA topoisomerase activities, this latter associated with antitumor activity[1].

Dihydroorotic acid

(S)-2,6-dioxo-hexahydro-Pyrimidine-4-carboxylic acid

4,5-Dihydroorotic acid, also known as dihydroorotate or hydroorotate is a pyrimidinemonocarboxylic acid that results from the base-catalysed cyclisation of N-alpha-carbethoxyasparagine. It is classified as a secondary amide, a monocarboxylic acid, a pyrimidinemonocarboxylic acid and a N-acylurea. 4,5-Dihydroorotic acid is a derivative of orotic acid which serves as an intermediate in pyrimidine biosynthesis. 4,5-Dihydroorotic acid exists in all living species, ranging from bacteria to plants to humans. 4,5-Dihydroorotic acid is synthesized by the enzyme known as Dihydroorotase (EC 3.5.2.3) which converts carbamoyl aspartic acid into 4,5-dihydroorotic acid as part of the de novo pyrimidine biosynthesis pathway (PMID: 13163076). 4,5-Dihydroorotic acid is also a substrate for the enzyme known as dihydroorotate dehydrogenase (DHODH). In mammalian species, DHODH catalyzes the fourth step in the de novo pyrimidine biosynthesis pathway, which involves the ubiquinone-mediated oxidation of dihydroorotate to orotate and the reduction of flavin mononucleotide (FMN) to dihydroflavin mononucleotide (FMNH2). Inhibition of DHODH activity with teriflunomide (an immunomodulatory drug) or expression with RNA interference results in reduced ROS generation and consequent apoptosis of transformed skin and prostate epithelial cells. Mutations in the DHOD gene have been shown to cause Miller syndrome, also known as Genee-Wiedemann syndrome, Wildervanck-Smith syndrome or post-axial acrofacial dystosis (PMID: 19915526). 4,5-Dihydroorotic acid is a substrate of the enzyme orotate reductase [EC 1.3.1.14], which is part of the pyrimidine metabolism pathway. (KEGG) Dihydroorotate is oxidized by Dihydroorotate dehydrogenases (DHODs) to orotate. These dehydrogenases use their FMN (flavin mononucleotide) prosthetic group to abstract a hydride equivalent from C6 to deprotonate C5 [HMDB] L-Dihydroorotic acid can reversibly hydrolyze to yield the acyclic L-ureidosuccinic acid by dihydrowhey enzyme[1].

It is used in foods as a firming agent, acidity regulator, sequestrant, stabiliser and thickener, and nutrient supplement (Ca source). It is used as an acidifier/preservative in bread, and in some gelling mixtures. Calcium acetate is a food additive, mainly in candy products.; Calclacite is a name for calcium acetate chloride pentahydrate, which is treated as mineral species but possess anthropogenic origin.; Patients with advanced renal insufficiency (creatinine clearance less than 30 ml/min) exhibit phosphate retention and some degree of hyperphosphatemia. The retention of phosphate plays a pivotal role in causing secondary hyperparathyroidism associated with osteodystrophy, and soft-tissue calcification. The mechanism by which phosphate retention leads to hyperparathyroidism is not clearly delineated. Therapeutic efforts directed toward the control of hyperphosphatemia include reduction in the dietary intake of phosphate, inhibition of absorption of phosphate in the intestine with phosphate binders, and removal of phosphate from the body by more efficient methods of dialysis. The rate of removal of phosphate by dietary manipulation or by dialysis is insufficient. Dialysis patients absorb 40\\% to 80\\% of dietary phosphorus. Therefore, the fraction of dietary phosphate absorbed from the diet needs to be reduced by using phosphate binders in most renal failure patients on maintenance dialysis. Calcium acetate when taken with meals combines with dietary phosphate to form insoluble calcium phosphate which is excreted in the feces. Maintenance of serum phosphorus below 6.0 mg/dl is generally considered as a clinically acceptable outcome of treatment with phosphate binders. Calcium acetate is highly soluble at neutral pH, making the calcium readily available for binding to phosphate in the proximal small intestine. It is used in foods as a firming agent, acidity regulator, sequestrant, stabiliser and thickener, and nutrient supplement (Ca source). It is used as an acidifier/preservative in bread, and in some gelling mixtures V - Various > V03 - All other therapeutic products > V03A - All other therapeutic products > V03AE - Drugs for treatment of hyperkalemia and hyperphosphatemia D064449 - Sequestering Agents > D002614 - Chelating Agents
