The CB(1) cannabinoid receptor antagonist SR-141716A (Rimonabant) markedly diminishes the behavioral effects of opiates and nicotine and has been an important tool to ascertain the role of cannabinoid receptors in drug addiction. The present goal was to determine the less-explored interaction of SR-141716A and d-amphetamine in neurochemical and behavioral assays. Additionally, the effect of the substituents and substitution patterns on the phenyl ring located at the 5 position of SR-141716A (4-chlorophenyl), and of the CB(1)/CB(2) cannabinoid receptor agonist WIN-55,212-2, was determined. SR-141716A, AM-251 (4-iodophenyl) and NIDA-41020 (4-methoxyphenyl) did not alter amphetamine-evoked [(3)H]overflow from rat striatal slices preloaded with [(3)H]dopamine. MRI-8273-30-1 (4-fluorophenyl; 0.1-10 microM) attenuated amphetamine (3 microM)-evoked [(3)H]overflow, and MRI-8273-59 (3,4-dichlorphenyl; 0.01-10 microM) augmented amphetamine (0.3-3 microM)-evoked [(3)H]overflow. WIN-55,212-2 was without effect. In a locomotor activity experiment, SR-141716A and MRI-8273-30-1 did not alter amphetamine-induced hyperactivity. However, MRI-8273-59 (1-3 mg/kg) dose-dependently attenuated amphetamine (1 mg/kg)-induced hyperactivity. The present results suggest that SR-141716A is less efficacious to alter amphetamine effects than its reported efficacy to diminish the effects of opiates and nicotine. Modification of the 5-phenyl position of SR-141716A affords compounds that do interact with amphetamine in vitro and in vivo.
