analysis. Initial anticonvulsant screening was performed using intraperitoneal (i.p.) maximal electroshock-induced seizure (MES), subcutaneous pentylenetetrazole (scPTZ), subcutaneous strychnine (scSTY), and subcutaneous picrotoxin (scPIC)-induced seizure threshold tests. A model involving 22-day old rat pups was also employed to further screen the effects of the test compounds against hyperthermia-induced
本研究旨在设计和合成新型的γ-氨基丁酸(GABA)衍生物与硫代半脲和GABA药效团的组合,以开发新型的抗惊厥药。报道的化合物被设计为GABA半咔唑的生物立体异构体。除元素分析外,还通过使用其光谱数据确认了合成化合物的结构。使用腹膜内(ip)最大电击诱发癫痫发作(MES),皮下戊四氮(scPTZ),皮下士丁宁(scSTY)和皮下pictotoxin(scPIC)诱发的癫痫发作阈值测试进行初始抗惊厥筛选。还采用了涉及22天大的幼鼠的模型来进一步筛选测试化合物对抗热疗诱导的高热惊厥的作用。在MES测试中,仅发现化合物1和11具有活性。发现大多数化合物在scPIC和高热惊厥模型中有效,只有极少数化合物在scPTZ和scSTY模型中显示出保护作用。这是有关这些新的GABA衍生物有效治疗高热惊厥的首次报道。
