Talk:Dimethyl fumarate

Sensitizer

According to YLE, study about dimethyl fumarate being a sensitizer should appear in British Journal of Dermatology soon. Article mentions author being Tapio Rantanen. I have no knowledge about field or access to journal's archives, so could someone else see if they can find the mentioned article? --Igno2 (talk) 21:30, 10 June 2008 (UTC)

Cost of Medical Dimethyl Fumarate vs. chemical

I am aware that the wholesale cost of Tecfidera (anti-Multiple Sclerosis drug; only ingredient is dimethyl fumarate, apparently) is $109 per 240 milligram capsule. An ordinary dose is one capsule per day, and thus a cost of about $40,000 per year. https://www.biogen.com/content/dam/corporate/en_us/pdfs/vermont-pricing-disclosure/3.18.2015.long-form-tecfidera.pdf Yet, Sigma-Aldrich sells dimethyl fumarate at $64 per 100 grams http://www.sigmaaldrich.com/catalog/search?term=Dimethyl+fumarate&interface=Product%20Name&N=0+&mode=mode%20matchpartialmax&lang=en&region=US&focus=productN=0%20220003048%20219853286%20219853269 , equivalent to over 400, 240 milligram capsules. (and Sigma-Aldrich isn't exactly known as a low-cost supplier, either!) In other words, a cost of about 16 U.S. cents per capsule, making Tecfidera about 700x more expensive. I'm very new to editing WP; but I think it would be desireable to include these facts in the dimethyl fumarate (and Multiple Sclerosis) articles. I understand that ideally, this would involve the use of secondary sources, but in some situations the use of primary sources (including those I've listed above) might be appropriate as well. Could somebody who is interested in this help me out here? Sluefoot (talk) 18:35, 7 September 2015 (UTC)

Reactions / Chemistry ==

Dimethyl fumarate is an ester and an α,β-unsaturated electrophilic compound which can quickly undergo Michael additions with nucleophiles. Dimethyl fumarate is also an effective diene acceptor in the thermal Diels-Alder reaction, where the reactivity of its vinylenic bond is enhanced by the two electron-withdrawing ester groups. Due to the geometry of the starting ester, the Diels-Alder product will have a trans configuration. With this reaction, compounds with bicyclo skeletons can be synthesized, e.g. a diester with a norbornene (bicyclo[2.2.1]heptene) skeleton from dimethyl fumarate and cyclopentadiene.

MMF

I might just point out that MMF is quite often used in medical literature to refer to mycophenolate mofetil, a medication used in immunology. Could be misleading having it refer to something else in this topic.
