Abstract

The dopamine D-3 receptor is predominantly expressed in limbic regions of the brain, such as the nucleus accumbens, island of Calleja and hippocampus, and is known to be associated with cognitive and emotional functions. This neuroanatomical distribution suggests that D-3 receptors may be importanttargets for the development of therapeutic treatments for schizophrenia and drug abuse. Several new compounds have been reported to display a greaterselectivity for D-3 receptors than D-2 receptors. For instance, both PD 128907 and 7-OH-DPAT were characterised as D-3 preferring receptor agonists in both binding and cellular studies, with the former compound being the most selective. Recent studies have suggested that the D-3 receptor subtype plays a pivotal role in the reinforcing effects of cocaine. The D-3 receptor may thus be a useful target for drug development of anticocaine medications. However, therapies based on mimicking the acute effects of abused drugs may be ineffective on compulsive drug-seeking, drug craving and relapse, which are the common critical problems in the treatment of drug addiction. Hence, liability for dependence on dopamine D-3 receptor agonists is a risk tobe taken into consideration. The close association of the D-3 receptor with mesolimbic dopaminergic circuits suggests that partial blockade of the D-3 receptor may selectively decrease the rewarding effects of cocaine without contributing to the dysphoria associated with cocaine withdrawal. The selective and partial D-3 receptor agonist BP 897 has the unprecedented property of reducing cocaine-seeking behaviour maintained by a cocaine-associatedcue. Compounds like BP 897 could be useful for reducing relapse vulnerability, with minimal liability of dependence. A review of recent patents of the dopamine agonists in the last four years suggest some potential therapeutic benefits from this class of drugs to treat psychiatric and neurologic diseases. it also outlines the utility of dopamine agonists in various new indications.
