  Melanocortin subtype-4 receptor agonists containing a piperazine core with substituted aryl sulfonamides

  摘要：

  The biological activity for a set of melanocortin-4 receptor (MC4R) agonists containing a piperazine core with an ortho-substituted aryl sulfonamide is described. Compounds from this set had binding and functional activities at MC4R less than 30 nM. The most selective compound in this series was > 25,000-fold more potent at MC4R than MC3R, and 490-fold more potent at MC4R than MC5R. This compound also reduced food intake after oral dosing at 25, 50, and 100 mg kg(-1) in fasted mice. (c) 2005 Elsevier Ltd. All rights reserved.

  摘要：

  Incorporation of substituted phenyl piperazine privileged structures into a known MC4 specific dipeptoid consensus sequence resulted in a series of potent (EC50 = 24 nM) and selective MC4-R agonists. We report the SAR of this series of compounds using in vitro cAMP functional assays in cells transfected with the MC4 or other melancortin receptors. (C) 2003 Elsevier Ltd. All rights reserved.

  The melanocortin receptors have been implicated as potential targets for a number of important therapeutic indications, including inflammation, sexual dysfunction, and obesity. We identified compound 1, an arylpiperazine attached to the dipeptide H-D-Tic-D-p-Cl-Phe-OH, as a novel melanocortin subtype-4 receptor (MC4R) agonist through iterative directed screening of nonpeptidyl G-protein-coupled receptor biased libraries. Structure-activity relationship (SAR) studies demonstrated that substitutions at the ortho position of the aryl ring improved binding and functional potency. For example, the o-isopropyl-substituted compound 29 (K-i = 720 nM) possessed 9-fold better binding affinity compared to the unsubstituted aryl ring (K-i = 6600 nM). Sulfonamide 39 (K-i = 220 nM) fills this space with a polar substituent, resulting in a further 2-fold improvement in binding affinity. The most potent compounds such as the diethylamine 44 (K-i = 60 nM) contain a basic group at this position. Basic heterocycles such as the imidazole 50 (K-i = 110 nM) were similarly effective. We also demonstrated good oral bioavailability for sulfonamide 39.
