Topiramate-d12

Topiramate-d12 is intended for use as an internal standard for the quantification of topiramate (Cay-13623) by GC- or LC-MS. Topiramate is a sugar sulfamate with anticonvulsant activity. It inhibits carbonic anhydrase in intact human erythrocytes (Ki = ~200 µM), as well as blocks sodium and calcium channels and kainate-induced currents in vitro. It also increases GABAA receptor-mediated chloride ion flux. Topiramate inhibits hind-limb tonic-extensor seizures in the maximal electroshock seizure test in mice (ED50 = 39 mg/kg, p.o.). Formulations containing topiramate have been used in the treatment of epilepsy and prophylaxis of migraine headaches.Formal Name: 2,3:4,5-bis-O-[1-(methyl-d3)ethylidene-2,2,2-d3]-beta-D-fructopyranose, 1-sulfamate.
