Диметилфумарат

Описание

In March 2013, the US FDA approved dimethyl fumarate for the treatment of relapsing forms of multiple sclerosis (MS). Dimethyl fumarate is the newest oral therapeutic for MS. While its mechanism is not completely understood, dimethyl fumarate increases anti-inflammatory cytokines (IL-10, IL-4, and IL-6), decreases proinflammatory cytokines (IL-1β, IL-6, and TNF-α), and activates the Nrf2 pathway to protect neuronal cells. Nrf2 is activated by covalent bond-forming electrophiles such as dimethyl fumarate, a Michael acceptor. Dimethyl fumarate has been used for the treatment of psoriasis in Europe since 1994 and has a favorable long-term safety profile. An exploratory study in patients with relapsing remitting MS showed significant reductions in MS lesions after 18 weeks of treatment with 720 mg/day of dimethyl fumarate. Evaluation of dimethyl fumarate in a mouse experimental autoimmune encephalomyelitis model of MS resulted in reduced spinal cord macrophage inflammation. Dimethyl fumarate is obtained in high purity by esterification of fumaric acid with methanol and catalytic sulfuric acid.

Использование

Dimethyl fumarate acts as an immunomodulator. It is also used in cycloaddition reactions involving ylides, benzenes and amino acids. It is added to food grains,tobacco,leather and preservation. Clothing

Определение

ChEBI: Dimethyl fumarate is an enoate ester resulting from the formal condensation of both carboxy groups of fumaric acid with methanol. Used for treatment of adults with relapsing forms of multiple sclerosis. It has a role as an immunomodulator and an antipsoriatic. It is an enoate ester, a methyl ester and a diester. It is functionally related to a methanol and a fumaric acid.

Общее описание

Dimethyl fumarate is a novel oral therapeutic agent, which can be used for patients suffering from relapsing-remitting multiple sclerosis. It shows an effective inhibition of mould in bread and can also serve as a potential candidate for the treatment of psoriasis, a chronic autoimmune condition.

Контактные аллергены

Dimethylfumarate, a strong irritant, is used as an industrial wide spectrum biocide in Asia and mainly in China, for textiles, leather, seeds, food, and cosmetic ingredients. It provoked a worldwide epidemic of severe contact dermatitis, initially from Chinese sofas sold in Finland, Great Britain, and France. It also induced severe burning and contact allergy due to shoes, and to contaminated clothing as well. This chemical, presents as is (white powder) or as tablets contained in little bags disposed in/or around the materials to protect, progressively evaporates and contaminates the environment. It is forbidden in the European Union since 2008
