Design and synthesis of novel small molecule N/OFQ receptor antagonists
摘要:
Small molecule N/OFQ receptor antagonists were designed and synthesized to further investigate the therapeutic potential of N/OFQ receptor modulators. The resulting octahydrobenzimidazol-2-ones 14 and 23 show excellent antagonistic activity towards both N/OFQ and mu receptors with high affinity to the human N/OFQ receptor. (C) 2003 Elsevier Ltd.
