The nomenclature of pyrimidines is straightforward. However, like other heterocyclics, tautomeric hydroxyl groups yield complications since they exist primarily in the cyclic amide form. 65-86-1, formula is C5H4N2O4, Name is 2,6-Dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylic acid. For example, 2-hydroxypyrimidine is more properly named 2-pyrimidone. A partial list of trivial names of various pyrimidines exists. Synthetic Route of 65-86-1.
Keerthisinghe, Tharushi Prabha;Yang, Qin;Chow, Agnes;Fang, Mingliang research published 《 Feeding state greatly modulates the effect of xenobiotics on gut microbiome metabolism: A case study of tetracycline》, the research content is summarized as follows. The human gut microbiome is crucial in modulating host health mostly through bacterial metabolites. Chem. exposure is typical external stress which alters its composition and functionality. To date, very few studies have investigated the effect of feeding state on chem.-induced gut microbial metabolic dysregulations. Here, we set up an in vitro human gut microbiome and incorporated a metabolomics approach to investigate the effect of tetracycline (TET) at multiple doses (i.e., 10, 1, and 0.01 mg/L) on gut microbiome under the fed and fasted states. Overall, the metabolome was highly responsive at the fed state with 62 metabolites dysregulated while only 14 were altered at the fasted state under 10 mg/L (clin. TET dose). As expected, nutrient consumption was significantly inhibited under clin. TET dose at the fed state accumulating nutrients such as glutamate and leucine. Interestingly, at the fed state, TET could increase the synthesis of indole and Ph derivatives including indole-3-aldehyde and hydrocinnamate, while inhibiting indoxyl, tryptamine, and vitamin B production, all of which have host health implications. Furthermore, metabolites like indoxyl and xanthurenic acid were still responsive at 0.01 mg/L (dietary TET dose). Collectively, results demonstrated that the feeding state greatly modulates the chem.-induced gut microbial metabolic alterations.
Synthetic Route of 65-86-1, Orotic acid anhydrous is a hydrogen bonding interaction that can be found in biological systems. It plays a role in the physiological effects of orotic acid, which is a metabolite of uridine and an intermediate in the synthesis of pyrimidine nucleotides. Orotic acid has antimicrobial properties and has been shown to inhibit enzyme activities involved in energy metabolism, such as polymerase chain reaction (PCR) and adenosine triphosphate (ATP) synthase. Orotic acid also inhibits the growth of bacteria, fungi, and parasites. Orotic acid anhydrous is used for treating myocardial infarcts or brain functions. The untreated group was given no treatment at all.
Orotic acid, also known as orotate or orotsaeure, belongs to the class of organic compounds known as pyrimidinecarboxylic acids. These are pyrimidines with a structure containing a carboxyl group attached to the pyrimidine ring. Orotic acid exists as a solid, slightly soluble (in water), and a moderately acidic compound (based on its pKa). Orotic acid has been found in human liver and pancreas tissues, and has also been primarily detected in saliva, feces, urine, and blood. Within the cell, orotic acid is primarily located in the cytoplasm and mitochondria. Orotic acid exists in all eukaryotes, ranging from yeast to humans. Orotic acid participates in a number of enzymatic reactions. In particular, Orotic acid can be biosynthesized from L-dihydroorotic acid and quinone; which is mediated by the enzyme dihydroorotate dehydrogenase (quinone), mitochondrial. In addition, Orotic acid and phosphoribosyl pyrophosphate can be converted into orotidylic acid through its interaction with the enzyme uridine monophosphate synthetase isoform a. In humans, orotic acid is involved in the pyrimidine metabolism pathway. Orotic acid is also involved in several metabolic disorders, some of which include the mngie (mitochondrial neurogastrointestinal encephalopathy) pathway, dihydropyrimidinase deficiency, UMP synthase deficiency (orotic aciduria), and Beta ureidopropionase deficiency. Outside of the human body, orotic acid can be found in a number of food items such as green vegetables, alaska blueberry, chickpea, and colorado pinyon. This makes orotic acid a potential biomarker for the consumption of these food products. Orotic acid is a potentially toxic compound. Orotic acid has been found to be associated with several diseases known as phosphoenolpyruvate carboxykinase deficiency 1, cytosolic and hyperornithinemia-hyperammonemia-homocitrullinuria; orotic acid has also been linked to several inborn metabolic disorders including n-acetylglutamate synthetase deficiency, lysinuric protein intolerance, and ornithine transcarbamylase deficiency.
Orotic acid appears as white crystals or crystalline powder.
Orotic acid is a pyrimidinemonocarboxylic acid that is uracil bearing a carboxy substituent at position C-6. It has a role as a metabolite, an Escherichia coli metabolite and a mouse metabolite. It derives from a uracil. It is a conjugate acid of an orotate., 65-86-1.
