  Benzimidazole-2-carboxamides as novel NR2B selective NMDA receptor antagonists

  摘要：

  A novel series of benzimidazole-2-carboxamide derivatives was prepared and identified as NR2B selective NMDA receptor antagonists. The influence of some structural elements, like H-bond donor groups placed on the benzimidazole skeleton and the substitution pattern of the piperidine ring, on the biological activity was studied. Compound 6a showed excellent analgetic activity in the mouse formalin test following po administration. (c) 2006 Elsevier Ltd. All rights reserved.
