The putative D2 dopamine receptor agonist quinpirole (LY 171,555) is the most widely used D2 agonist in in vivo and in vitro studies of D2 receptor-mediated effects. In addition, quinpirole may have even higher affinity for the recently described D3 dopamine receptor. The present study describes the in vitro binding properties of newly developed [3H]quinpirole in rat brain. [3H]Quinpirole binding was characterized in striatal membrane homogenate preparations using a filtration assay… CONTINUE READING
