Sulfamides are promising functions for the design of new antiepileptic drugs (Bioorg. Med. Chem. 2007, 15, 1556-1567; 5604-5614). Following previous research in this line, a set of amino acid-derived sulfamides has been designed, synthesized, and tested as new anticonvulsant compounds. The experimental data confirmed the ability of some of the structures to suppress the convulsions originated by the electrical seizure (MES test) at low doses (100 mg/kg).
Synthesis of pseudonucleosides containing chiral sulfahydantoins as aglycone (II)
A series of chiralsulfahydantoins have been synthesized by alkaline cyclization starting from N-sulfamylaminoacid methyl esters. Regioselective glycosylation of these pseudopyrimidic heterocycles was carried out with a benzyl protecting group on the N-sulfonylcarbamic position. Best glycosylation results were obtained by preliminary silylation of sulfahydantoins, and their condensation with a tetraacylribofuranose
