A series of four N-benzylamides of gamma-hydroxybutyric acid (GHB), that contain N-(4-phenylpiperazine)-, N-(4-benzylpiperazine)rings, N-benzylamino-, or N-(2-phenylethylamine)-groups in the alpha-position of GHB were selected as model compounds, for determining the structural elements responsible for their potential anticonvulsant action. Based on the results of pharmacological, physicochemical, and
γ-羟基丁酸(GHB)的一系列四个N-苄基酰胺,它们包含N-(4-苯基哌嗪)-,N-(4-苄基哌嗪)环,N-苄基氨基-或N-(2-苯基乙胺)-选择GHBα-位的基团作为模型化合物,以确定负责其潜在抗惊厥作用的结构元素。根据药理,理化和分子模型研究的结果,定义了GHB抗惊厥性N-取代酰胺的药效团模型。在该模型中,N-苄基酰胺片段的存在对于活性至关重要。此外,所有酰胺均包含另一个疏水单元(芳环)作为远端结合位点和氢键供体。考虑到这些模型参数,许多GHB的N-取代酰胺含有疏水部分,例如:制备了在GHB的α位的N-苄氨基或N-(4-氯苄氨基)基团,以及在酰胺部分的亲脂取代基。已经显示,新合成的化合物的抗惊厥活性可以部分基于它们的亲脂性(计算的log P值)和分子中羟基的存在来解释。
