In this study, we designed and synthesized heterobivalent ligands targeting heteromers consisting of the metabotropic glutamate 5 receptor (mGluR5) and the dopamine D2 receptor (D2R). Bivalentligand 22a with a linker consisting of 20 atoms showed 4-fold increase in affinity for cells coexpressing D2R and mGluR5 compared to cells solely expressing D2R. Likewise, the affinity of 22a for mGluR5 increased

This report describes the design and synthesis of novel heterobivalent ligands for dopamine D2‐like receptors (D2‐likeR) and the μ‐opioid receptor (μOR) and their evaluation using ligand binding and functional assays. Interestingly, we identified a potent bivalent ligand that contains a short 18‐atom linker and combines good potency with high efficacy both in β‐arrestin 2 recruitment for μOR and MAPK‐P

attractive approach to investigate and control GPCR dimerization may be provided by the exploration and characterization of bivalentligands, which can act as molecular probes simultaneously binding two adjacent binding sites of a dimer. The synthesis of bivalent dopamine D2 receptor ligands of type 1 is presented, incorporating the privileged structure of 1,4-disubstituted aromatic piperidines/piperazines
