new N-(2-(1,1-dimethyl-5,7-dioxo-4,6-diazaspiro[2.4]heptan-6-yl)ethyl) sulfonamide derivatives (8a–i) and ethyl 2,2-dimethyl-1-(3-(2-(sulfonamido)ethyl)ureido) cyclopropanecarbox-ylate derivatives (9a–i) were designed, synthesized and evaluated for their anticonvulsant activities using maximal electroshock shock (MES) and subcutaneous pentylenetetrazole (scPTZ) seizure models in mice. N-(2-(1,1-dimethyl-5
一系列新的N-(2-(1,1-二甲基-5,7-二氧代-4,6-二氮杂螺[2.4]庚-6-6基)乙基)磺酰胺衍生物(8a – i)和乙基2,2使用最大的电击休克(MES)和皮下戊四唑(scPTZ)设计,合成并评估了-二甲基-1-(3-(2-(磺酰胺基)乙基)脲基)环丙烷甲酸酯衍生物(9a – i)的抗惊厥活性。小鼠的癫痫发作模型。N-(2-(1,1-二甲基-5,7-二氧杂4,6-二氮杂螺[2.4]庚-6-6基)乙基)-4-氟苯甲磺酰胺(8f)和N-(2-( 1,1-二甲基-5,7-二氧代-4,6-二氮杂螺[2.4]庚-6-6基)乙基)-4-甲基苯磺酰胺(8e)已经在MES模型中显示出有希望的抗惊厥活性。活性最高的化合物8f在小鼠腹膜内注射后显示出MES诱发的癫痫发作,ED 50值为28.05 mg / kg,TD 50值为561 mg / kg,这为化合物8f提供了保护指数(TD 50 / ED
