dopamine D2 receptor protomer rather than bridging interactions at two orthosteric sites across a dopamine D2 receptor dimer. This research has the potential to advance the development of structurally related bitopic ligands, biomarkers such as radioligands and fluorescently labeled probes, and furnish new homo- and heterobivalent ligands towards a better understanding of the dopamine D2 receptor and potential

A set of fourteen 4-(2-[N-propyl-N-alkyl-(or alkylaryl-) amino]ethyl)-2-indolone analogues of dopamine were synthesized in 15 steps and evaluated for their affinities towards the D-2 receptor using [H-3]sulpiride or [H-3]spiperone as radioligands. Six analogues displayed D-2 agonist activities comparable (K-i = 450650 nM) to Ropinirole or SK&F 101468. The functionalized amino side chain introduced in the 4-position can be used to modulate the lipophilicity of the analogues without significantly affecting D-2 activity.
