  N-Hydroxypyrazolyl Glycine Derivatives as Selective N-Methyl-d-aspartic Acid Receptor Ligands

  摘要：

  A series of analogues based on N-hydroxypyrazole as a bioisostere for the distal carboxylate group of aspartate have been designed, synthesized, and pharmacologically characterized. Affinity studies on the major glutamate receptor subgroups show that these 4-substituted N-hydroxypyrazol-5-yl glycine (NHP5G) derivatives are selectively recognized by N-methyl-D-aspartic acid (NMDA) receptors and that the (R)enantiomers are preferred. Moreover, several of the compounds are able to discriminate between individual subtypes among the NMDA receptors, providing new pharmacological tools. For example, 4-propyl NHP5G is an antagonist at the NR1/NR2A subtype but an agonist at the NR1/NR2D subtype. Molecular docking studies indicate that the substituent protrudes into a region that may be further exploited to improve subtype selectivity, thereby opening up a design strategy for ligands which can differentiate individual NMDA receptor subtypes.
