  Bivalent molecular probes for dopamine D2-like receptors

  摘要：

  Merging two arylamidoalkyl substituted phenylpiperazines as prototypical recognition elements for dopamine D-2-like receptors by oligoethylene glycol linkers led to a series of bivalent ligands. These dimers were investigated in comparison to their monomeric analogues for their dopamine D-2long, D-2short, D-3 and D-4 receptor binding. Radioligand binding experiments revealed strong bivalent effects for some para-substituted benzamide derivatives. For the D-3 subtype, the target compounds 32, 34 and 36 showed an up to 70-fold increase of affinity and a substantial enhancement of subtype selectivity when compared to the monovalent analogue 24. Analysis of the binding curves displayed Hill slopes very close to one indicating that the bivalent ligands displace 1 equiv of radioligand. Obviously, the two pharmacophores occupy an orthosteric and an allosteric binding site rather than adopting a receptor-bridging binding mode. (C) 2011 Elsevier Ltd. All rights reserved.
