2-ethyl-3-methyl-butyl-carbamate (34) and 2-ethyl-3-methyl-pentyl-carbamate (38) also exhibited potent activity in the pilocarpine-SE model 30 min postseizure onset. Extending the aliphatic side chains of homologous carbamates from 7 to 8 (34 to 35) and from 8 to 9 carbons in the homologues 38 and 43 decreased the activity in the pilocarpine-SE model from ED50 = 81 mg/kg (34) to 94 mg/kg (35) and from 96 mg/kg (38)
合成了一类新型的19种氨基甲酸酯,并在大鼠最大电击(MES)和皮下甲硝唑(scMet)癫痫发作测试和毛果芸香碱引起的癫痫持续状态(SE)模型中比较了它们的抗惊厥活性。尽管所述烷基氨基甲酸酯紧密的结构特征,仅化合物34,38,和40都处于活动状态的MES试验。癫痫发作后30分钟,类似物2-乙基-3-甲基-丁基-氨基甲酸酯(34)和2-乙基-3-甲基-戊基-氨基甲酸酯(38)也表现出有效的活性。将同源氨基甲酸酯的脂族侧链从7延伸到8(34到35)和同源物38和43中的8至9个碳降低了毛果芸豆SE模型中的活性,从ED 50 = 81 mg / kg(34)降至94 mg / kg(35)和96 mg / kg(38)。分别达到114 mg / kg(43)。最有效的氨基甲酸酯,苯基-乙基-氨基甲酸酯(47)(MES ED 50 = 16 mg / kg)在其结构中包含一个芳香族部分。化合物34,
