anticonvulsant activity. The study was designed to determine the effect of varying the carbocyclic (ring A) nucleus, while maintaining the heterocyclic ring constant, on anticonvulsant activity. Results indicate that maximum activity was obtained with the ring A comprised of a six-membered spiro ring system, 2a, one methylene group greater than that previously reported for N-(benzyloxy)-2-azaspiro[4
合成了一系列螺琥珀酰亚胺,并评估了其抗惊厥活性。该研究旨在确定在维持杂环恒定的同时改变碳环(环A)核对抗惊厥活性的影响。结果表明,环A包含六元螺环系统2a,比先前报道的N-(苄氧基)-2-氮杂螺[4.4]壬烷-1,3-所报道的亚甲基大,获得的最大活性。 dione,1,原型类似物。化合物2a在MES测试中具有活性,并提供100 mg / kg的保护,螺十二烷类似物2g也是如此。X射线分析显示,活性2a和非活性螺辛烷类似物2f之间存在显着差异。但是,这些差异不能解释螺十二烷类似物2g表现出的意外活性。
