  Synthesis and biological evaluation of new GABA-uptake inhibitors derived from proline and from pyrrolidine-2-acetic acid

  摘要：

  Several synthetic approaches to N-alkylated derivatives of 4-hydroxypyrrolidine-2-carboxylic acid and 4-hydroxypyrrolidine-2-acetic acid are described. The final compounds have been evaluated as potential inhibitors of the GABA transport proteins GAT-I and GAT-3. The biological assays used were based on bovine material or porcine brain. As compared to the corresponding 4-unsubstituted compounds, the 4-hydroxypyrrolidine-2-carboxylic acid and 4-hydroxypyrrolidine-2-acetic acid derivatives showed a significant decrease in the inhibitory potency at both GAT-1 and GAT-3 with only four compounds having reasonable affinity to GAT-1 (IC50: 5.1, 6.6 and 9.4 mu M) or GAT-3 (IC50:19.9 mu M), respectively. The biological data of the 4-hydroxypyrrolidine-2-acetic acid derivatives indicates that (2S)-configuration at the C-2 position for potent inhibition of GAT-1 and (4R)-configuration at the C-4 position for potent inhibition of GAT-3 may be crucial.

The study comprised derivatives substituted in 2- as well as in 3-position with either an acetic acid moiety or a carboxylic acid function. In addition, azetidine derivatives bearing a tetrazole ring as a bioisosteric substitute for a carboxylic

  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。

  We synthesized proline and pyrrolidine-2-alkanoic acid derivatives in their enantiomerically pure form and evaluated them for their affinity to the GABA transport proteins GAT-1 and GAT-3. Among the compounds presented herein, (R)-pyrrolidine-2-acetic acid (R)-4d substituted with a 2- [tris(4-methoxyphenyl)methoxy] ethyl residue at the nitrogen atom showed the highest affinity at GAT-3 (IC50 = 3.1 mu M) comparable with the well-known GAT-3 blocker (S)-SNAP-5114. Compound (R)-4d displayed excellent subtype selectivity for GAT-3 (GAT-3:GAT-1 = 20:1). (S)-2-pyrrolidineacetic acid derivatives (S)-4b provided with a 4,4-diphenylbut-3-en-1-yl moiety and (S)-4c substituted with a 4,4-[di(3-methylthiophen-2-yl)]phenylbut-3-en-l-yl residue at the nitrogen atom exhibited IC50 values of 0.396 mu M and 0.343 mu M at the GAT-1 protein, respectively.
