Synthesis and Pharmacological Evaluation of Potent and Highly Selective D<sub>3</sub> Receptor Ligands: Inhibition of Cocaine-Seeking Behavior and the Role of Dopamine D<sub>3</sub>/D<sub>2</sub> Receptors
The synthesis, pharmacological evaluation, and structure-activity relationships (SARs) of a series of novel arylalkylpiperazines structurally related to BP897 (3) are described. In binding studies, the new derivatives were tested against a panel of dopamine, serotonin, and noradrenaline receptor subtypes. Focusing mainly on dopamine D(3) receptors, SAR studies brought to light a number of structural

in binding and functional studies was lower than previously reported. All analogues were determined to be D2R/D3R agonists in both GoBRET and mitogenesis functional assays. Loss of efficacy was detected for the N-1-substituted analogues at D3R. In contrast, the N-5-alkyl-substituted analogues, and notably the n-butyl-arylamides (22b and 22c), all showed improved affinity at D2R over 1 with neither a
