exhibit high affinity and selectivity for GAT-1. In the present paper we describe the design and synthesis of a novel series of triarylnipecotic acid derivatives for evaluation as GABA uptake inhibitors. The design lead for this series of compounds was the nonselective GABA uptake inhibitor EGYT-3886, [(-)-2-phenyl-2-[(dimethylamino)ethoxy]-(1R)- 1,7,7-trimethylbicyclo[2.2.1]heptane]. From this series of
γ-氨基丁酸(GABA)是哺乳动物中枢神经系统中的主要抑制性神经递质。分子生物学揭示了大脑中存在四种高亲和力GABA转运蛋白,即GAT-1,GAT-2,GAT-3和BGT-1,后者转运GABA和渗透压甜菜碱。我们已经表明,已知的GABA吸收抑制剂,例如SK&F 89976-A,CI-966和替加宾对TiTabine具有高亲和力和对GAT-1的选择性。在本文中,我们描述了一系列新的三芳基庚酸衍生物的设计和合成,以评估其作为GABA摄取抑制剂。该系列化合物的设计先导是非选择性GABA吸收抑制剂EGYT-3886,[(-)-2-苯基-2-[(二甲基氨基)乙氧基]-(1R)-1,7,7-三甲基双环[2.2]。 1]庚烷]。来自该系列化合物(S)-1- [2- [三(4-甲氧基苯基)甲氧基]乙基] -3-哌啶甲酸+(S)-1- [2- [三(4-甲氧基苯基)甲氧基]乙基] -3-哌啶羧酸+++酸4(
