The dose response curve for apomorphine reversal of γ-butyrolactone (GBL)-induced L-DOPA accumulation in rat striatum was shifted almost 6-fold to the right after partial irreversible blockade (83%) of dopamine (DA) autoreceptors with N-ethoxycarbonyl-2-ethoxy-1,2-dihydroquinoline (EEDQ); however, the maximal response was not reduced. In contrast, the major effect of a similar degree of irreversible blockade (86%) on the dose-response curve for the autoreceptor-selective agent EMD 23,448 was a reduction in maximal response (60% of control), indicating that EMD 23,448 is a partial agonist. A large receptor reserve therefore exists at the DA autoreceptor, which may explain in part why many DA agonists are more potent in models pre- than postsynaptic receptor activation.
