title: Anticonvulsant O-alkyl sulfamates. 2,3:4,5-Bis-O-(1-methylethylidene)-beta-D-fructopyranose sulfamate and related compounds.
abstract: Novel sugar sulfamate 1 (McN-4853, topiramate) has been found to exhibit potent anticonvulsant activity analogous to that of phenytoin. In the maximal electroshock seizure test, orally at 2 h in mice, 1 had an ED50 of 39 mg/kg. Orally, 1 had a duration of action in excess of 8 h. Other aspects of the pharmacology of 1, as well as neurochemistry and carbonic anhydrase inhibition, are discussed. The conformational behavior of 1 in solution and in the solid state is discussed. A series of analogues of 1 were synthesized and examined for anticonvulsant properties.
