As shown by autoradiography, peripheral injections of N-ethoxycarbonyl-2-ethoxy-1,2-dihydroquinoline (EEDQ) induced a dose-dependent decrease of [3H]SCH 23390 and [3H]prazosin high-affinity binding sites in the rat prefrontal cortex. EEDQ showed similar efficacy in inactivating cortical and striatal dopamine (DA) D1 receptors, whereas prazosin-sensitive alpha 1-adrenergic receptors were more sensitive to the action of the alkylating agent, as for all doses of EEDQ tested (from 0.8 to 3 mg/kg, i… CONTINUE READING
