分别测定了SCH-23390和多潘立酮对离体脾动脉和直肠尾肌多巴胺受体的拮抗力。SCH 23390是血管(PA2=10.65)受体的竞争性拮抗剂,但不是神经元(PA26.0)受体的拮抗剂。多潘立酮是神经性受体(PA2=7.9)的竞争性拮抗剂,而不是血管受体(PA2<4.0)。因此,SCH 23390和多潘立酮分别是高选择性的血管和神经多巴胺受体拮抗剂。
The antagonist potencies of SCH 23390 and domperidone have been determined at vascular and neuronal dopamine receptors in the habbit isolated splenic artery and rectococcygeus muscle, respectively. SCH 23390 was a potent, competitive antagonist at vascular (pA2=10.65) but not neuronal (pA2<6.0) receptors. Domperidone was a potent, competitive antagonist at neuronal (pA2=7.9) but not vascular (pA2<4.0) receptors. SCH 23390 and domperidone are, therefore, highly selective vascular and neuronal dopamine receptor antagonists respectively.
