Two series of new derivatives of pyrrolidine-2,5-dione were synthesized and evaluated for their anticonvulsant properties. Initial screening for their anticonvulsant properties was performed in mice after intraperitoneal administration, using the maximal electroshock (MES), subcutaneous pentylenetetrazole (scPTZ) and 6-Hz seizure tests. Quantitative pharmacological research revealed that the highest
合成了两个新的吡咯烷-2,5-二酮衍生物,并对其抗惊厥性质进行了评估。使用最大电击(MES),皮下戊烯四唑(sc PTZ)和6 Hz癫痫发作试验在腹膜内给药后在小鼠中进行抗惊厥特性的初步筛选。定量药理研究表明,化合物N -[4-甲基哌嗪-1-基}-甲基] -3-(1-苯乙基)-吡咯烷-2,5-二酮一盐酸盐显示出最高的保护作用(22),在sc PTZ测试(ED 50 = 39 mg / kg)和6 Hz测试(ED 50 = 36 mg / kg)。该分子显示出比参比抗癫痫药(如乙琥胺,拉考酰胺和丙戊酸)更高的效力。为了解释所选分子的可能作用机理,在体外评估了其对钠和钙通道以及NMDA和GABA A受体结合特性的影响。
