In this publication, we describe the synthesis of new inhibitors for the GABA transporter subtypes GAT1 and especially GAT3. We started with 3-aminopropanoic acid possessing a distinct preference for GAT3 in comparison to GAT1 and furthermore its homolog 3-aminobutanoic acid. A series of respective N-substituted amino acids was synthesized by selective N-monoalkylation of these parent structures with
在该出版物中,我们描述了GABA转运蛋白亚型GAT1,尤其是GAT3的新抑制剂的合成。我们从与GAT1及其同系物3-氨基丁酸相比,对GAT3具有明显偏爱的3-氨基丙酸开始。通过Mitsunobu型反应用6种不同的芳基烷基醇选择性地将这些母体结构进行N-单烷基化反应,合成了一系列各自的N-取代氨基酸。研究了所得化合物的抑制效能GABA转运蛋白亚型。在所有测试的化合物的4,4-二苯基丁-3-烯基取代的3-氨基丁酸(外消旋) - 6b中显示最高效力用的pIC 50GAT1的值为5.34。不幸的是,2- [三(4-甲氧基苯基)甲氧基]乙基取代的衍生物的预期GAT3效力不如相应的乳酸盐衍生物所观察到的那样高。
