Orotic acid is a minor dietary constituent. 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 and is synthesized in the body, where it arises as an intermediate in the pathway for the synthesis of pyrimidine nucleotides. Orotic acid is converted to UMP by UMP synthase, a multifunctional protein with both orotate phosphoribosyl transferase and orotidylate decarboxylase activity. The most frequently observed inborn error of pyrimidine nucleotide synthesis is a mutation of the multifunctional protein UMP synthase. As a result, plasma orotic acid accumulates to high concentrations, and increased quantities appear in the urine. Orotic acid levels are elevated in the urea cycle defects ornithine transcarbamylase (OTC) deficiency, citrullinemia and argininosuccinic acidemia, as well as the mitochondrial transport disorder hyperornithinemia-hyperammonemia-homocitrullinuria (HHH) syndrome. Orotic acid is also elevated in hereditary orotic aciduria, or uridine monophosphate synthase deficiency, an autosomal recessive disorder characterized by megaloblastic anemia and crystalluria. In addition, orotic acid in combination with leflunomide is in the phase II of clinical trial to evaluate the clinical efficacy and safety of a combination in kidney transplant patients with high levels of Polyoma BK viruria for the purpose of preventing polyoma BK viremia and nephropathy, that could lead to kidney transplant loss from viral damage, acute rejection or both.

Disodiurn salt of Arsonoacetic acid has been used in veterinary to treat anaplasmosis (babesiasis); as general stimulant in nervous disease; for eclampsia of bitches, and with adjuncts in chronic eczema and follicular mange. Arsonoacetic acid has not featured much in human medicine, a Chinese patent however, was filed in 2003 for arsonoacetic acid and its methyl or ethyl derivatives as chemotherapeutic drugs again liver cancer.

Clodronate (also known as clodronic acid) is a drug used to treat a high level of calcium in the blood caused by changes in the body that happen with cancer. Clodronate is approved in some countries and is sold under trade trade name bonefos for oral use. Bonefos is indicated in the management of osteolytic lesions, hypercalcemia and bone pain associated with skeletal metastases in patients with carcinoma of the breast or multiple myeloma. Bonefos is also indicated for the maintenance of clinically acceptable serum calcium levels in patients with hypercalcemia of malignancy initially treated with an intravenous bisphosphonate. Bonefos forms complexes with divalent metal ions, and therefore simultaneous administration with food, antacids and mineral supplements may impair absorption. It was suggested, that the mechanism of action of clodronate was involved osteoclast apoptosis.

Glucuronic acid is a sugar acid that was first identified in urine. It is an intermediate metabolite of the uronic acid pathway. Moreover, glucuronic acid is involved in detoxification of certain drugs and toxins by conjugating with them and forming glucuronides. Glucuronic acid has been found to cause an increase in TLR4-dependent reporter protein expression in a cell line transfected with TLR4 and associated co-signaling molecules, and can cause TLR4-dependent pain in humans.

Brilliant Blue is an organic compound classified as a blue triarylmethane dye. It is coal tar derivative food dye; used as the di-NH4 or di-Na salts. Coloring agent. Brilliant Blue FCF, has been used in foods in the US since 1929. This color adds a distinctive, bright blue hue to beverages, beverage powders, dairy products, baked goods, dessert powders, confections, condiments, icings, syrups, jams, jellies, marmalades, liqueurs, extracts, dairy fats and oil, meat, seafood, snacks, dry mixes and seasonings, fruit preparations, convenient food, and flavors. Both the diammonium and disodium salts of FD&C Blue No. 1 are used. The disodium salt is used in foods, while the diammonium salt has limited usage in drugs and cosmetics.
