  • Title: Design and synthesis of 6-amino-1,4-oxazepane-3,5-dione derivatives as novel broad spectrum anticonvulsants.
    Author: Sharma G, Park JY, Park MS.
    Journal: Bioorg Med Chem Lett; 2008 Jun 01; 18(11):3188-91. PubMed ID: 18479918.
    Abstract:
    Based on the structural estimations of the typical anticonvulsant drugs, a series of 6-amino-1,4-oxazepane-3,5-dione derivatives, novel structures of 7-membered heterocyclic imides, which were hybridized with pharmacophores such as cyclic imide and N-CO-C-N group in their molecule were designed and synthesized. Their anticonvulsant activities were evaluated by the maximal electroshock induced seizure (MES) and subcutaneous pentylenetetrazole (PTZ) tests. Almost all the designed compounds except 1c and 1f showed comparable anticonvulsant activities in at least one of the anticonvulsant tests. Moreover, some of the tested compounds exhibited moderate anticonvulsant activities in both MES and PTZ tests. From these results, 6-amino-1,4-oxazepane-3,5-dione derivatives could be recommended as novel structures of broad spectrum anticonvulsants.
