The aim of this paper was to describe the synthesis of a library of 28 new 1,3-substituted pyrrolidine-2,5-dione as potential anticonvulsant agents. The anticonvulsant activity was evaluated using three acute models of seizures in mice (MES-maximal electroshock, scPTZ-subcutaneous pentylenetetrazole, and 6Hz-psychomotor seizure tests). The neurotoxicity was determined by rotarod test. The most promising
本文的目的是描述28种新的1,3-取代的吡咯烷-2,5-二酮作为潜在的抗惊厥药的文库的合成。使用三种急性癫痫发作模型(MES最大电击,scPTZ-皮下戊四氮和6Hz精神运动性癫痫发作测试)评估抗惊厥活性。神经毒性通过旋转脚架试验确定。发现最有希望的化合物是N-[吗啉-1-基}-甲基] -3-苯甲酰基-吡咯烷-2,5-二酮(15),因为它在MES中有活性(ED50 = 41.0mg / kg),scPTZ(ED50 = 101.6kg / mg)和6Hz(ED50 = 45.42mg / kg)测试。该化合物显示出比抗癫痫药(如乙硫磺酰亚胺,拉考酰胺和丙戊酸)更有益的保护指数(PI)。
