on the development of new anticonvulsants, 16 new1-(8-(benzyloxy)quinolin-2-yl-6-substituted-4,6-diazaspiro[2,4]heptane-5,7-diones were synthesized and tested for anticonvulsant activity using the maximal electroshock (MES), subcutaneous pentylenetetrazole (scPTZ) screens, which are the most widely employed seizure models for early identification of candidate anticonvulsants. Their neurotoxicity was
在目前的新型抗惊厥药的研究中,合成了16种新的1-(8-(苄氧基)喹啉-2-基-6-取代的4,6-二氮杂螺[2,4]庚烷-5,7-二酮,并使用最大电击(MES)皮下戊四氮(sc PTZ)筛查抗惊厥活性,这是最广泛使用的癫痫发作模型,可早期鉴定候选抗惊厥药,通过旋翼试验确定了它们的神经毒性,显示了两种化合物8e和8j两种用于抗惊厥评估的模型均具有良好的抗惊厥活性,活性最高的化合物8e显示出由MES引起的癫痫发作,ED 50值为8.6 mg / kg,TD 50腹膜内注射给小鼠后,其值为365.3mg / kg ,在MES测试中,化合物8e的保护指数(TD 50 / ED 50)为26.8。
