    Description

    Dimethyl fumarate (DMF) is the methyl ester of fumaric acid. DMF was initially recognized as a very effective hypoxic cell radiosensitizer. Later, DMF combined with three other fumaric acid esters (FAE) was licensed in Germany as oral therapy for psoriasis (trade name Fumaderm). Other diseases, such as necrobiosis lipoidica, granuloma annulare, and sarcoidosis were also found to respond to treatment with DMF in case reports or small patient series. Phase III clinical trials found that DMF (BG-12) successfully reduced relapse rate and increased time to progression of disability in multiple sclerosis (trade name Tecfidera). DMF is thought to have immunomodulatory properties without significant immunosuppression.
    In a non-medical use, DMF was applied as a biocide in furniture or shoes to prevent growths of mold during storage or transport in a humid climate. However, due to incidences of allergic reactions after skin contact the European Union banned DMF in consumer products since 1998, and since January 2009 the import of products containing DMF was also banned.
