A series of new 2,5-disubstituted-1,3,4-oxadiazole derivatives 8(a-o) was synthesized by the reaction of 1-(5-
phenyl-1,3,4-oxadiazol-2-yl)piperazine with various sulfonyl chlorides. The synthesized compounds were 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 (MES) seizure method and compared with the standard
drug phenytoin. The neurotoxic effects were determined by rotorod test. Compounds 8d, 8e and 8f were found to be most
potent of this series. The same compounds showed no neurotoxicity at the maximum dose administered (100 mg/kg). The
efforts were also made to establish the structure activity relationships among synthesized compounds.
一系列新的2,5-二取代-1,3,4-噁二唑衍生物8(a-o)通过1-(5-苯基-1,3,4-噁二唑-2-基)哌嗪与各种磺酰氯的反应合成。合成的化合物通过元素分析、核磁共振氢谱(1H NMR)、碳谱(13C NMR)和质谱研究进行了表征。新合成的化合物经过对抗惊厥活性筛选,采用最大电休克发作(MES)方法,并与标准药物苯妥英进行比较。神经毒性作用通过转棒测试确定。化合物8d、8e和8f在本系列中显示出最强的抗惊厥活性。这些化合物在最大给药剂量(100 mg/kg)下未显示出神经毒性。还努力建立了合成化合物之间的结构活性关系。
