dc.description.abstractSyntheses of nineteen new compounds are described, twelve of which are N-substituted derivatives of 1,2-benzisothiazolin-3-one-1,1-dioxide (saccharin): [structure]. New and improved syntheses of N-carboxymethyl-saccharin are reported; these procedures require short reaction time and give yields of 65-79%. Attention was focused on the study of two series: series 1 (n = 1-4, x = 3-(5,5-diphenylhydantionyl) and series 2 (n = 1-4, x = 3-(5,5-dimethyl-2,4-oxazolidine-dionyl). Spectral properties (mass, proton magnetic resonance, and infrared spectra) of these compounds were obtained and interpreted. Characteristic differences in the spectral details of ring and functional moieties allow easy identification of these compounds as well as products of biotransformation. When the above two series were screened for anticonbulsant activity, the compounds exhibited more versatility, though less effectiveness, than the parent anticonvulsants in protection against electrical and chemically-induced seizures in mice. For both series, compounds having two-carbon linkage showed maximum biological activity.en
