1-acylamino-2-benzimidazolinones. The latter compounds were obtained in two steps from o-nitro-β-acylphenylhydrazines. All of the 1-amino-2-benzimidazolinones exhibited activity in the standard anticonvulsant tests except for the 1-benzylamino compound. The most active compound was 1-ethylamino-2-benzimidazolinone which protected mice in the maximal electroshock seizure test at 30 mg/kg.
通过将1-酰基氨基-2-苯并咪唑啉酮的双(2-甲氧基乙氧基)氢化铝钠还原,可以制备在氨基氮上具有烷基取代基的1-氨基-2-苯并咪唑啉酮。后者的化合物从邻-硝基-β-酰基苯基肼分两步获得。除1-苄基氨基化合物外,所有的1-氨基-2-苯并咪唑啉酮类均在标准抗惊厥试验中表现出活性。活性最高的化合物是1-乙基氨基-2-苯并咪唑啉酮,它在最大电击惊厥试验中以30 mg / kg的剂量保护小鼠。
