CGS 10746B, a dopamine release inhibitor with properties similar to the atypical antipsychotic clozapine, was assessed as to its behavioral properties using spontaneous locomotor activity and the conditioned place preference test. Rats conditioned with interperitoneally administered doses of 1.25, 2.5, 5.0, 10.0, 20.0 or 30.0 mg/kg CGS 10746B showed a conditioned place aversion, whereas only doses of 5.0 mg/kg or greater suppressed locomotor activity. Results are discussed in terms of dopaminergic mediation of conditioned place preference and spontaneous locomotor activity and methodological concerns involved in employing the conditioned place preference test with drugs that produce opposing affective cues.
