test. The results of sc-PTZ test indicate that a majority of compounds possessed anticonvulsant activity with long duration of protection effects. Among of them, compound 6k was found to be the most promising one, with an ED50 value of 20.4 mg/kg (in sc-PTZ model) and a PI value of 10.8, possessing higher anti-PTZ activity and wider safety margin than valproate and ethosuximide.
一系列2-(((5-芳氧基-1-甲基-3-甲基-1H-吡唑-4-基)亚甲基)肼甲酰胺(6a-6l)和2-((5-5-芳氧基-1-甲基-3-设计并合成了苯基-1H-吡唑-4-基)亚甲基)肼甲酰胺(7a-7l)。在小鼠中最大的电击休克(MES)和皮下戊四氮(sc-PTZ)癫痫发作模型用于评估合成化合物的抗癫痫作用。此外,还通过旋转脚架试验研究了急性神经毒性特征。sc-PTZ测试结果表明,大多数化合物具有抗惊厥活性,并且具有长效的保护作用。其中,化合物6k被认为是最有前途的化合物,ED50值为20.4 mg / kg(在sc-PTZ模型中),PI值为10.8,比丙戊酸盐具有更高的抗PTZ活性和更宽的安全裕度和ethosuximide。
