uric acid

Uric Acid (Lithic acid) is an oxidation product of oxypurines such as XANTHINE and HYPOXANTHINE. It is the final oxidation product of purine catabolism in humans and primates, whereas in most other mammals URATE OXIDASE further oxidizes it to ALLANTOIN.

Uric acid sodium, scavengers of oxygen radicals, is a potent and common antioxidant that helps maintain stable blood pressure and resist oxidative stress. Uric acid sodium, which removes reactive oxygen species (ROS) such as singlet oxygen and peroxynitrite, has an inhibitory effect on lipid peroxidation and is associated with the pathogenesis of gout joint disease and the formation of calcium oxalate stones.

Citric acid trilithium salt tetrahydrate (Lithium citrate tribasic tetrahydrate) , the active component of Lithium, is a medicine used in the therapy of psychiatric disease. It has shown the effects of signaling pathways and metabolic in the brain based on the particular disease and clinical condition model. According to the reports, Citric acid trilithium salt tetrahydrate was used as a mood stabilizer when treating bipolar mood disorders (BD) and lower the risk of self-harm in BD patient. In addition,Citric acid trilithium salt tetrahydrate has been the choice drug in the therapy of acute manic episodes.Citric acid trilithium salt tetrahydrate also could dissolve uric acid crystals in urine achieved from patients with gout. Besides,Citric acid trilithium salt tetrahydrate have some dose-dependent side-effects. The the main side-effects of Lithium Citrate is the tendency to inhibit the prostatic acid phosphatase enzyme (PAP), which result in the accumulation of PAP.

Hypoxanthine (Purin-6-ol), also known as purine-6-ol or Hyp. Hypoxanthine is a naturally occurring purine derivative and a reaction intermediate in the metabolism of adenosine and in the formation of nucleic acids by the nucleotide salvage pathway. Under normal circumstances hypoxanthine is readily converted to uric acid.hypoxanthine is first oxidized to xanthine, which is further oxidized to uric acid by xanthine oxidase.

Xanthine (Isoxanthine) is a product on the pathway of purine degradation. Xanthine is subsequently converted to uric acid by the action of the Xanthine oxidase enzyme. Xanthine is found in most body tissues and fluids in various organisms. Biologically Xanthine is produced from guanine by cypin (guanine deaminase). Furthermore, Xanthines act as antagonists for adenosine receptors, with selectivity depending on whether there are substitution of alkyl groups.

Purine (7H-Imidazo(4,5-d)pyrimidine) is a heterocyclic aromatic organic compound, consisting of a pyrimidine ring fused to an imidazole ring. Two of the bases in nucleic acids, adenine and guanine, are purines. Purines from food (or from tissue turnover) are metabolised by several enzymes, including xanthine oxidase, into uric acid. High levels of uric acid can predispose to gout when the acid crystalises in joints; this phenomenon only happens in humans and some animal species (e.g. dogs) that lack an intrinsic uricase enzyme that can further degrade uric acid.

Alloxan is an acidic compound formed by the oxidation of URIC ACID.

Allantoic acid, a byproduct of uric acid degradation, is implicated in purine metabolism [1][2][3].
