Stereoselective synthesis and preliminary evaluation of new d-3-heteroarylcarbonylalanines as ligands of the NMDA receptor
摘要:
New N-heteroarylcarbonylalanines of the D-series were stereoselectively prepared from enoates derived from D-mannitol. These compounds were active in binding and functional assays of the NMDA sub-type of glutamate receptors. A pyridine derivative inhibited MK801 binding, protected neurons from excitotoxic damage and blocked NMDA-induced currents in neurons. A thiophene derivative positively modulated the NMDA receptor, possibly through the allosteric glycine site. (C) 2004 Elsevier Ltd. All rights reserved.
