  The synthesis of novel GABA uptake inhibitors. 1. Elucidation of the structure-activity studies leading to the choice of (R)-1-[4,4-bis(3-methyl-2-thienyl)-3-butenyl]-3-piperidinecarboxylic acid (Tiagabine) as an anticonvulsant drug candidate

  摘要：

  A series of different synthetic approaches to novel GABA uptake inhibitors are described, leading to examples which are derivatives of nipecotic acid and guvacine, substituted at nitrogen by 4,4-diaryl-3-butenyl or 2-(diphenylmethoxy)ethyl moieties. The in vitro value for inhibition of [H-3]-GABA uptake in rat synaptosomes was determined for each compound. It was found that the most potent examples are those having a substituent in an ''ortho'' position in one or both aromatic/heteroaromatic groups. The majority of the compounds described are structurally related to tiagabine, (R)-1-[4,4-bis(3-methyl-2-thienyl)-3-butenyl]-3-piperidinecarboxylic acid hydrochloride (NNC 05-0328) and some of the reasoning behind the selection of this compound as a drug candidate is summarized.

  of GAT1, but similar compounds, such as proline, are very weak binders. When substituted with 4,4‐diphenylbut‐3‐en‐1‐yl (DPB) or 4,4‐bis(3‐methylthiophen‐2‐yl)but‐3‐en‐1‐yl (BTB) groups, the resulting compounds have similar pKi and pIC50 values, even though the pure amino acids have very different values. To investigate if small amino acids and their substituted counterparts share a similar binding mode

  著名的γ-氨基丁酸（GABA）转运蛋白抑制剂GAT1共有一个小环状氨基酸的共同骨架，该小环状氨基酸通过烷基链连接到带有两个芳香环的部分上。Tiagabine是唯一经过FDA批准的GAT1抑制剂，就是一个典型的例子。一些小的氨基酸，如（R）-戊二酸，是GAT1的中等至强结合剂，而类似的化合物，例如脯氨酸，则是非常弱的结合剂。当被4,4-二苯基丁-3-烯-1-基（DPB）或4,4-双（3-甲基噻吩-2-烯基）但是3-烯-1-基（BTB）基团取代时，得到的化合物的p K i和pIC 50相似即使纯氨基酸具有非常不同的值，也可以使用这些值。为了研究小氨基酸及其取代的对等体是否具有相似的结合模式，我们合成了小氨基酸的丁基，DPB和BTB取代衍生物。受对接研究结果的支持，我们不仅针对未取代和取代的氨基酸，还针对强结合和弱结合氨基酸提出了不同的结合方式。这些数据得出的结论是，采用基于片段的方法，不应使用
