the present study on the development of new anticonvulsants, twenty new N-3-arylamide substituted 5,5-cyclopropanespirohydantoin derivatives 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
在当前有关新型抗惊厥药的研究中,合成了二十种新的N-3-芳基酰胺取代的5,5-环丙烷螺并氢胆碱衍生物,并使用最大电击(MES),皮下戊四氮(sc PTZ)筛查了其抗惊厥活性。最广泛使用的癫痫发作模型来早期识别候选抗惊厥药。他们的神经毒性是通过转子试验来确定的。在用于抗惊厥评估的两个模型中,三种化合物5d,5j和5t均显示出有希望的抗惊厥活性。活性最高的化合物5j显示出MES引起的癫痫发作,ED 50值为9.2 mg / kg和TD腹膜内注射给小鼠后的50值为421.6 mg / kg,这在MES测试中为化合物5j提供了45.8的保护指数(TD 50 / ED 50)。
