Synthesis and anticonvulsant activity of new N-1′,N-3′-disubstituted-2′H,3H,5′H-spiro-(2-benzofuran-1,4′-imidazolidine)-2′,3,5′-triones
摘要:
Thirteen new N-1',N-3'-disubstituted-2'H,3H,5'H-spiro-(2-benzofuran-1,4'-imidazolidine)-2',3,5-triones were synthesized and their pharmacological activity determined with the objective to better understand their SAR for anticonvulsant activity. The anticonvulsant effects of these compounds were evaluated by standard pentylenetetrazol (scPTZ test) and maximum electroshock seizure (MES test) models in mice. Most of the compounds showed ability to protect against the pentylenetetrazol-induced convulsions. Compound 3o (the N-1'-p-nitrophenyl, N-3'-ethyl derivative) in the N-1'-aryl, N-3'-alkyl disubstituted series exhibited maximum activity with ED50 of 41.8 mg/kg in scPTZ convulsion model.

PdII-catalyzedaromatic C–H bondactivation using urea as a directinggroup was achieved in a p-TsOH/AcOH medium under mild reaction conditions. The direct olefination products of various urea derivatives were produced from aryl urea derivatives and butyl acrylate in moderate to good yields.

The Preparation and Characterization of Nineteen New Phthalidyl Spirohydantoins

日期:——
Nineteen new N,N'-disubstituted phthalidyl spirohydantoins (6a-s) were prepared for the purpose of pharmacological testing. Their structure was deduced from the IR, H-1-NMR, C-13-NMR, mass spectra and elemental analysis. The two possible structural isomers - only one of which is formed - can be distinguished unequivocally on the basis of selective diastercotopicity of the alpha-methylene hydrogens adjacent to N-3' of the hydantoin ring.
