  Novel piperazines: Potent melanocortin-4 receptor antagonists with anxiolytic-like activity

  摘要：

  In the present study, we found that a novel piperazine compound, 11a, showed a moderate affinity (IC50 = 333 nM) for the MC4 receptor. We developed the new type of piperazine compounds and found that mono-piperazine 11b exhibited a high-affinity (IC50 = 40.3 nM) for the MC4 receptor. We also found that a series of biphenyl analogues exhibited a high-affinity for the receptor, and in particular, compound 11j exhibited the highest affinity for the MC4 receptor with an IC50 value of 14.5 nM. Further-more, some of these compounds, when administered orally, significantly reversed the stress-induced anxiety-like behavior in rats. In this paper, we report the synthesis, structure-activity relationships, and oral activity of the novel mono-piperazines as MC4 receptor antagonists. (c) 2007 Elsevier Ltd. All rights reserved.
