A series of novel 1-[5-(4-methoxy-phenyl)-[1,3,4]oxadiazol-2-yl]-piperazine derivatives 8(a–o) were synthesized and characterized by elemental analyses, 1H NMR, 13C NMR and mass spectral studies. The newly synthesized compounds were screened for their anticonvulsant activity against maximal electroshock seizure (MES) model in male wistar rats and compared with the standard drug phenytoin. The neurotoxic
合成了一系列新型的1- [5-(4-甲氧基-苯基)-[1,3,4]恶二唑-2-基]-哌嗪衍生物8(a - o),并通过元素分析,1 H NMR进行了表征,13 C NMR和质谱研究。筛选了新合成的化合物对雄性Wistar大鼠最大电击惊厥(MES)模型的抗惊厥活性,并与标准药物苯妥英钠进行了比较。通过使用小鼠的旋翼试验确定神经毒性作用。化合物8d,8e,8f和8h被发现是本系列中最有力的。相同的化合物在最大给药剂量(100 mg / kg)下无神经毒性。还努力建立合成化合物之间的结构活性关系。药效团模型用于验证合成分子的抗惊厥活性。
