Orotic acid Usage And Synthesis
General DescriptionOrotic acid (also known as pyrimidinecarboxylic acid) is a heterocyclic acid; it is also known as. Historically it was believed to be part of the vitamin B complex and was called vitamin B13, but it is now known that it is not a vitamin. It is well known as a precursor in biosynthesis of pyrimidines; in mammals it is released from the mitochondrial dihydroorotate dehydrogenase (DHODH) for conversion to UMP by the cytoplasmic UMP synthase enzyme[1]. OA is also a normal part of the diet, being found in milk and dairy products[5], and it is converted to uridine for use in the pyrimidine salvage pathway predominantly in liver, kidney and erythrocytes. Before its essential role as an intermediate of pyrimidine biosynthesis was established in the 1950s[3], the compound OA was discovered in whey (Greek oros) by Biscaro and Belloni (1905)[4]. Since then it has received attention from several different aspects. For example, it is proposed that the dietary orotate is beneficial for animals and humans obviously arose from its considerable natural amounts in milk and dairy products[5]. In addition, it also draw great attention from its medical potentials such as improvement of learning behavior of adult rats, neuro-protective effect for gerbils and cats under transient cerebral ischemia, and optimization of functions in normal and ischemic rat hearts[6-9].
MetabolismOrotate [orotic acid, OA] is the product of dihydroorotate dehydrogenase [DHODH], the fourth enzyme of pyrimidine [UMP] de novo synthesis [Fig. 1]. It is abundant in the serum and particularly urine of patients suffering from hereditary orotic academia or from enzyme defects in the urea cycle[10]. The sequence of six chemical reactions of UMP de novo synthesis is conserved from microorganisms to humans [Figure 1], although the organization of enzymes involved is different in eukaryotes[11-13]. In mammals, the six enzymes are coded by only three genes. The tri-functional CAD enzyme and the bifunctional UMP synthase each contain their appropriate catalytic activities on one polypeptide chain. The product of the third gene, dihydroorotate dehydrogenase [DHODH] holds a mitochondrial targeting sequence and a transmembrane domain at the N-terminus, which enable the enzyme to find its place in the inner mitochondrial membrane[14]. Through its electron acceptor, ubiquinone, DHODH is functionally united with the respiratory chain and can contribute to energy conservation in mitochondria. In turn, the formation of orotic acid [OA] by mitochondria, and hence the de novo synthesis of UMP, is strictly aerobic. In growth processes OA can be considered as a metabolic link between environmental oxygen tension and the proliferative capacity of cells[15].
ApplicationsOverview
Orotic Acid is used in the preparation of therapeutic agents for chronic obstructive pulmonary disease [COPD] treatment[16]. As it is an intermediate in de novo pyrimidine biosynthesis, it may be used to study the specificity and kinetics of orotate phosphoribosyltransferase [OPRT] which catalyzes the reversible phosphoribosyl transfer from 5′-phospho-α-d-ribose 1′-diphosphate [PRPP] to orotic acid [OA], forming pyrophosphate and orotidine 5′-monophosphate [OMP][17]. Orotic acid can also be used as a starting material for the potential commercial bio-production of uridine 5′-monophosphate [UMP] by microbes such as Corynebacterium ammoniagenes [ATCC 6872] or Saccharomyces cerevisiae. Moreover, it may be used to study the AMPK/SREBP-1 dependent cell-signaling pathway and transcription regulation mechanisms associated with the induction hepatic lipogenesis[17].
Medical aspects
OA has strong pharmacological potentials. The improvement of learning behavior of adult rats, neuro-protective effect for gerbils and cats under transient cerebral ischemia, and optimization of functions in normal and ischemic rat hearts were generally assigned to the precursor role of OA in cells for pyrimidine nucleotides and RNA[6-9]. The development of complexes and salts with metal ions [Mg2+, Zn2+, Ca2+, K+] and organic cations [e.g. choline, carnitine] exploited the favorable carrier function of OA for transportation and delivery of these ligands in living organisms to compensate deficiency syndromes[5]. Likewise, the construction of platinum, palladium and tin coordination compounds with OA for administration in cancer chemotherapy followed this principle[18]. The positive impact of OA preparations claimed for humans are highlighted by promises given in the public domain, such as beneficial cardiovascular effects, energy provision, improvement of body composition, and enhanced athletic performance.
Study has also shown that OA may lower the serum cholesterol and lipid[19-21]. Orotic acid also has strong uricosuric effect, originating from its role as a true transport substrate for the anion exchangerURAT1 [encoded by human SLC22A12 gene] located at the luminal site of the tubule cells[22].
Dietary aspects
The assumption that dietary orotate is beneficial for animals and humans obviously arose from its considerable natural amounts in milk and dairy products[5]. In the 1970s OA was proposed to increase the UDP-glucuronate pool for hepatic detoxification of bilirubin in the treatment of neonatal jaundice[5]. Another, underestimated, benefit of OA in the diet of newborns may be the establishment of the anaerobic OA-degrading intestinal microflora. Overall, it has strong potential to become a growth-enhancer for livestock.
Central Nervous systems
OA’s benefit for the brain, mentioned earlier, deserves closer attention. It can be assumed that a continuous supply of pyrimidine nucleotides is essential not only for the developing central nervous system[23], but equally for its plasticity, regeneration and neurotransmission: for example, some metabotropic P2Y receptor subtypes are sensitive to uridine nucleotides[24]. OA has putative protective and improvement effects of pyrimidine nucleotide pools, RNA synthesis, receptor saturation, repairing of ischeamia-induced membrane damage, which is explained by the function of OA as an intermediate in de novo UMP synthesis[25, 26].
Research field
OA had became a compound of considerable interest as a tool for studying pyrimidine metabolism in cells, tissues and animals: monitoring precursors, nucleotide pools and the rate of RNA synthesis, differentiating between de novo and salvage/recycling pathways, searching for antimetabolites and anticancer drugs[27, 29]. Concurrently, the growth-promoting features of OA were still of interest, and OA was used on animals and humans, with various biochemical rationales, assumptions and expectations[28, 30]. When OA was an additive to pharmaceutical preparations, its benefits were attributed to its being an intermediate of pyrimidine biosynthesis and therefore augmenting uridine nucleotide pools which are required for nucleic acid synthesis and for all pyrimidine nucleotide dependent biosynthetic processes[31, 32].

Air & Water ReactionsSlightly soluble in water.
Reactivity ProfileCarboxylic acids, such as Orotic acid, donate hydrogen ions if a base is present to accept them. They react in this way with all bases, both organic (for example, the amines) and inorganic. Their reactions with bases, called "neutralizations", are accompanied by the evolution of substantial amounts of heat. Neutralization between an acid and a base produces water plus a salt. Carboxylic acids with six or fewer carbon atoms are freely or moderately soluble in water; those with more than six carbons are slightly soluble in water. Soluble carboxylic acid dissociate to an extent in water to yield hydrogen ions. The pH of solutions of carboxylic acids is therefore less than 7.0. Many insoluble carboxylic acids react rapidly with aqueous solutions containing a chemical base and dissolve as the neutralization generates a soluble salt. Carboxylic acids in aqueous solution and liquid or molten carboxylic acids can react with active metals to form gaseous hydrogen and a metal salt. Such reactions occur in principle for solid carboxylic acids as well, but are slow if the solid acid remains dry. Even "insoluble" carboxylic acids may absorb enough water from the air and dissolve sufficiently in Orotic acid to corrode or dissolve iron, steel, and aluminum parts and containers. Carboxylic acids, like other acids, react with cyanide salts to generate gaseous hydrogen cyanide. The reaction is slower for dry, solid carboxylic acids. Insoluble carboxylic acids react with solutions of cyanides to cause the release of gaseous hydrogen cyanide. Flammable and/or toxic gases and heat are generated by the reaction of carboxylic acids with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides. Carboxylic acids, especially in aqueous solution, also react with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat. Their reaction with carbonates and bicarbonates generates a harmless gas (carbon dioxide) but still heat. Like other organic compounds, carboxylic acids can be oxidized by strong oxidizing agents and reduced by strong reducing agents. These reactions generate heat. A wide variety of products is possible. Like other acids, carboxylic acids may initiate polymerization reactions; like other acids, they often catalyze (increase the rate of) chemical reactions.
