A series of ten compounds (Compounds J1 – J10) of (±) 3-menthone aryl acid hydrazone was synthesized and characterized by thin layer chromatography and spectral analysis. Synthesized compounds were evaluated for anticonvulsant activity after intraperitoneal (i.p) administration to mice by maximal electroshock (MES) and subcutaneous pentylenetetrazole (scPTZ) induced seizure method and minimal clonic seizure test. Minimal motor impairment was also determined for these compounds. Results obtained showed that four compounds out of ten afforded significant protection in the minimal clonic seizure screen at 6 Hz. Compound J6, 4-Chloro-N-(2-isopropyl-5-methylcyclohexylidene) benzohydrazide was found to be the most active compound with MES ED50 of 16.1 mg/kg and protective index (pI) of greater than 20, indicating that (±) 3-menthone aryl acid hydrazone possesses better and safer anticonvulsant properties than other reported menthone derivatives viz. menthone Schiff bases, menthone semicarbazides and thiosemicarbazides.
合成并表征了一系列十种(±)3-薄荷酮芳基酸肼酮化合物(化合物J1 – J10),采用薄层层析和光谱分析进行表征。合成的化合物经过腹腔注射(i.p)后,通过最大电击(MES)和皮下注射戊二腈(scPTZ)诱导癫痫发作的方法以及最小阵挛性发作测试评估了其抗惊厥活性。同时也确定了这些化合物的运动损伤最小值。结果显示,十种化合物中有四种在6 Hz的最小阵挛性发作筛选中提供了显著保护。化合物J6,4-氯-N-(2-异丙基-5-甲基环己烯基)苯肼被发现是最活跃的化合物,其MES ED50为16.1 mg/kg,保护指数(pI)大于20,表明(±)3-薄荷酮芳基酸肼酮具有比其他报道的薄荷酮衍生物(如薄荷酮希夫碱、薄荷酮半肼和硫半肼)更好和更安全的抗惊厥特性。
