Dimethyl maleate is an organic compound, the (Z)-isomer of the dimethyl ester of fumaric acid. Dimethyl maleate can be synthesized from maleic anhydride and methanol, with sulfuric acid acting as acid catalyst, via a nucleophilic acyl substitution for the monomethyl ester, followed by a Fischer esterification reaction for the dimethyl ester. Dimethyl maleate is used in many organic syntheses as a dienophile for diene synthesis. It is used as an additive and intermediate for plastics, pigments, pharmaceuticals, and agricultural products. It is also an intermediate for the production of paints, adhesives, and copolymers.

CNS Activity

Curator's Comment: Dimethyl fumarate is probably too hydrophilic to cross the blood-CNS barrier. DMF stabilized the BBB by preventing disruption of interendothelial tight junctions and gap formation, and decreased matrix metalloproteinase activity in brain tissue.

Originator

Curator's Comment: In September 2003, Biogen (now Biogen Idec) licensed exclusive worldwide rights (excluding Germany) from Fumapharm to develop and market BG 12.

Sample Use Guides

In Vivo Use Guide
Curator's Comment: In group of dogs experimental Fanconi syndrome (generalized proximal tubular dysfunction) was induced with maleic acid (25 mg/kg iv, pH 7.3). https://www.ncbi.nlm.nih.gov/pubmed/1858895
462 mg twice daily
Route of Administration: Oral
In Vitro Use Guide
Curator's Comment: Maleic acid-induced inhibition of sugar and amino acid transport in the rat renal tubule was studied.
NK cells from healthy controls were treated with 10 and 100 uM of monomethyl fumarate for 12 hours then washed and co-cultured for 24 hours at 1:5 E:T ratio with or without autologous labeled T cells. Using CD107a expression to measure NK cell degranulation, is was noted an increase in the proportion of degranulated NK cells following treatment with different monomethyl fumarate concentrations. These changes occurred without dramatic effects on NK cell viability.
