known. In the past decade, various aryl semicarbazones have been designed that were structurally dissimilar from many common anticonvulsants containing the dicarboximide function (CONRCO), which may contribute to toxic side effects. In the present work various N4-(2,6-dimethylphenyl) semicarbazones were designed as pharmacophore hybrids between the aryl semicarbazones and ameltolide. A three-dimensional
癫痫病是已知的最常见的原发性神经系统疾病。在过去的十年中,已设计出各种芳基半咔唑酮,它们在结构上与许多常见的含有二羧酰亚胺功能(CONRCO)的抗惊厥药不同,后者可能会导致毒副作用。在目前的工作中,各种N4-(2,6-二甲基苯基)半咔唑酮被设计为芳基半咔唑酮与阿美脲内酯之间的药效基团杂化物。建立了抗惊厥药的三维四点药效团模型,发现标题化合物与雷利替林匹配。当通过腹膜内和口服途径给药时,所有化合物在最大电击试验中均表现出抗惊厥活性。化合物N1-(2,6-二甲基苯基)-N4-(2-羟基苯甲醛)半卡巴zone(9)作为具有广谱抗惊厥剂活性的原型出现在五种没有神经毒性和肝毒性的癫痫发作模型中。化合物9在体外和离体中都将4-氨基丁酸(GABA)水平提高了118%,并抑制了GABA转氨酶。
