A number of novel pyrrole[1,2-a]pyrazine derivatives were synthesized and evaluated in in vivo animal models of epilepsy. Among them, several compounds displayed promising seizure protection in the maximal electroshock seizure (MES), subcutaneous metrazol seizure (scMET), 6 Hz and pilocarpine-induced status prevention (PISP) tests, with ED50 values comparable to the reference anticonvulsant drugs (AEDs)
合成了许多新颖的吡咯[1,2- a ]吡嗪衍生物,并在癫痫的体内动物模型中进行了评估。其中,几种化合物在最大电击惊厥(MES),皮下甲硝唑惊厥(scMET),6 Hz和毛果芸香碱引起的状态预防(PISP)测试中显示出有希望的癫痫保护作用,其ED 50值可与参考抗惊厥药(AEDs)相提并论。 )。观察到吡咯[1,2- a ]吡嗪核心的立体化学和构象偏好对体内药理活性的关键影响。合成药物的抗惊厥作用机制很可能不是通过抑制电压依赖性钠(Na+)电流。
