Recent studies have shown that the novel dopamine (DA) D 3 receptor antagonists SB-277011A and NGB 2904 inhibit cocaine-and/or stress-induced reinstatement of drug-seeking behavior. The present study sought to determine if SB-277011A, NGB 2904, or BP-897 (a mixed D 3 agonist/ antagonist) similarly inhibit cocaine-associated cue-induced reinstatement of drug-seeking behavior. Long-Evans rats were allowed to self-administer cocaine. Each cocaine infusion was paired with discrete conditioned cue-light and tone. Subsequently, drug-seeking (i.e., leverpressing) behavior was extinguished in the absence of cocaine and cocaine-associated cues. Rats were then tested for cue-induced reinstatement of drug-seeking. We found that cocaine-associated cues evoked robust reinstatement of lever-pressing. Acute intraperitoneal (i.p.) administration of SB-277011A (6, 12, or 24 mg/kg) produced a dose-dependent inhibition of cue-induced reinstatement of drug-seeking behavior by 35, 65, and 85%, respectively, compared to vehicletreated animals. Acute i.p. administration of NGB 2904 (0.1, 1.0, or 5.0 mg/kg) produced a 45, 30, and 70% inhibition of cue-induced reinstatement, respectively, compared to vehicle-treated animals. Acute i.p. administration of either 0.1 or 1 mg/kg of BP 897 did not produce a significant effect on cue-induced reinstatement, whereas a dose of 3 mg/kg produced a 70% inhibition of cueinduced reinstatement. These findings, combined with previous data, suggest that DA D 3 receptor antagonism may underlie the inhibitory effects of SB-277011A and NGB 2904 on cocaine cueinduced reinstatement, while the effects of BP 897 may involve D 3 and non-D 3 receptor mechanisms.
