Abstract

The racemic mixture and the (-)enantiomer of the putative dopamine autoreceptor agonist 3-PPP were investigated in vitro using dopamine-sensitive adenylate cyclase in homogenates of rat striatum as a model for a postsynaptic D1-receptor type and inhibition of electrically-evoked tritium overflow from rat striatal slices preincubated with [3H]choline and [3H]dopamine as a model for a postsynaptic D2- and a presynaptic dopamine autoreceptor type, respectively. In contrast, to apomorphine, neither the racemic mixture nor the (-)enantiomer exerted any effect, suggesting agonistic properties in all three receptor models. However, both (+/-)3-PPP and (-)3-PPP were weak antagonists at postsynaptic D1- and D2-receptors. The results of the present investigation suggest that the in vivo effects of 3-PPP are either the result of metabolic activation or that this drug activates an other dopamine autoreceptor type, pharmacologically different from that one modulating dopamine release.
