title: Synthesis and anticonvulsant evaluation of 6-amino-1,4-oxazepane-3,5-dione derivatives.
abstract: The N-Acyl-alpha-aminosuccinimides and N-Acyl-alpha-aminoglutarimides were reported to exhibit moderate anticonvulsant activities. These compounds were 5-membered or 6-membered alpha-amino cyclic imides and have N-CO-C-N moiety in their structures. Based on these structural characteristics, a series of 6-amino-1,4-oxazepine-3,5-dione derivatives 1, having a heterocyclic 7-memberd alpha-amino cyclic imide and N-CO-C-N moiety in their structures were designed and synthesized. These syntheses were in view to develop novel anticonvulsant compounds. The 6-amino-1, 4-oxazepine-3,5-dione derivatives were prepared from (S)-N-Cbz-serine by usual synthetic procedures and their anticonvulsant activities were examined by the MES and PTZ tests. The N-H (1a), N-methyl (1b), and N-n-butyl (1e) derivatives showed moderate anticonvulsant activities in the MES test. In the case of PTZ test, all the tested compounds except N-n-propyl compound(1c) also showed moderate anticonvulsant activities. Moreover, N-H (1a), N-methyl (1b), and N-n-butyl (1e) derivatives showed anticonvulsant activities in both the MES and PTZ test. From these studies, it was concluded that the 6-amino-1,4-oxazepane-3,5-dione derivatives were novel compounds enough to be recommended as new anticonvulsants.
