  Piperazine-2,3-dicarboxylic Acid Derivatives as Dual Antagonists of NMDA and GluK1-Containing Kainate Receptors

  摘要：

  Competitive N-methyl-D-aspartate receptor (NMDAR) antagonists bind to the GluN2 subunit, of which there are four types (GluN2A-D). We report that some N-1-substituted derivatives of cis-piperazine-2,3-dicarboxylic acid display improved relative affinity for GluN2C and GluN2D versus GluN2A and GluN2B. These derivatives also display subtype selectivity among the more distantly related kainate receptor family. Compounds 18i and (-)-4 were the most potent kainate receptor antagonists, and 18i was selective for GluK1 versus GluK2, GluK3 and AMPA receptors. Modeling studies revealed structural features required for activity at GluK1 subunits and suggested that S674 was vital for antagonist activity. Consistent with this hypothesis, replacing the equivalent residue in GluK3 (alanine) with a serine imparts 18i antagonist activity. Antagonists with dual GluN2D and GluK1 antagonist activity may have beneficial effects in various neurological disorders. Consistent with this idea, antagonist 18i (30 mg/kg ip) showed antinociceptive effects in an animal model of mild nerve injury.

  N1-取代的哌嗪-2,3-二羧酸衍生物作为NMDA受体拮抗剂的合成与药理作用。

  摘要：

  竞争性NMDA受体拮抗剂的结合位点位于NR2亚基上，其中有四种类型（NR2A-D）。典型的拮抗剂，例如（R）-AP5，具有亚单位选择性为NR2A> NR2B> NR2C> NR2D。竞争性NMDA受体拮抗剂（2R，3S）-（1-联苯基-4-羰基）哌嗪-2,3-二羧酸（PBPD，16b）与NR2A和NR2B相比，对NR2C和NR2D的相对亲和力增强，显示出非同寻常的选择性。合成了16b的带有芳基或芳基取代基的哌啶-2,3-二羧酸的N（1）连接基团的类似物，以探讨NR2C / NR2D选择性的结构要求。菲-2-羰基类似物16e对NR2C和NR2D的亲和力高> 60倍，对NR2C / NR2D的选择性是NR2A / NR2B的3-5倍。菲-3-羰基类似物（16f）的效力较低，但选择性更高，分别对NR2D的选择性是NR2A和NR2B的5倍和7倍。因此，带有大量疏水残基的拮抗剂具有与典型拮抗剂不同的NR2亚基选择性。
