Maleic acid (cis-butenedioic acid) is the cis-isomer of fumaric acid (trans-butenedioic acid). In industry, maleic acid is derived by hydrolysis of maleic anhydride, the latter being produced by oxidation of benzene or butane. Maleic acid is an industrial raw material for the production of glyoxylic acid by ozonolysis. Maleic acid is also used as an adhesion promoter for different substrates, such as nylon and zinc coated metals e.g galvanized steel, in methyl methacrylate based adhesives. The major industrial use of maleic acid is its conversion to fumaric acid. This conversion, an isomerization, is catalysed by a variety of reagents, such as mineral acids and thiourea. According to the California Environmental Protection Agency, the statewide emission rate of maleic anhydride from industrial facilities is estimated at 3340 kg/year. Maleic acid is also used as an adhesive in dentistry, as well as a fragrance ingredient and pH adjuster in many cosmetic and pharmaceutical products at low concentrations (0.004%). The large difference in water solubility makes fumaric acid purification easy. Some bacteria produce the enzyme maleate isomerase, which is used by bacteria in nicotinate metabolism. Maleic acid may be used to form acid addition salts with drugs to make them more stable. Many drugs that contain amines are provided as the maleate acid salt, e.g. carfenazine, chlorpheniramine, pyrilamine, methylergonovine, and thiethylperazine.

In Vivo Use Guide

in cow: The aim of this study was to determine the influence of fumaric acid (FA) on ruminal fermentation and its effects on the acid-base balance of seven ruminally and duodenally fistulated multiparous German Holstein cows. The experiment was conducted in a change-over design with three periods in which the animals were randomly arranged in one of three treatments: Control (C; without FA), 300 or 600 g FA per day. The diets consisted of 7.4 kg DM grass silage, 4.2 kg concentrate mixture and 0, 300 or 600 g FA or wheat starch as isocaloric compensation per day and cow. FA supplementation decreased the rumen pH, acetic acid and butyric acid and increased propionic acid in rumen fluid. The results of the single-strand conformation polymorphism analysis (SSCP) did not show an influence of FA on the microbial population in the rumen

In Vitro Use Guide

It was evaluated the effects of fumaric acid (FA) on tyrosinase activity and structure via enzyme kinetics and computational simulations. FA was found to be a reversible inhibitor of tyrosinase and its induced mechanism was the parabolic non-competitive inhibition type with IC50=13.7±0.25mM and Kislope=12.64±0.75mM. Kinetic measurements and spectrofluorimetry studies showed that FA induced regional changes in the active site of tyrosinase. One possible binding site for FA was identified under the condition without L-DOPA. The computational docking simulations further revealed that FA can interact with HIS263 and HIS85 at the active site. Furthermore, four important hydrogen bonds were found to be involved with the docking of FA on tyrosinase. By inhibiting tyrosinase and its central role in pigment production, FA is a potential natural antipigmentation agent.
