profile of a selective autoreceptor agonist and was half as active as 3-PPP. However, resolution of the compound revealed that the 8R enantiomer was an unselective DA agonist with a profile similar to (+)-3-PPP, while the 8S enantiomer was a weak DA antagonist without any DA agonist activity. The unsaturated quinolizidine derivative 21 also had the profile of a DA antagonist while the axial quinolizidine
合成了8种3-PPP的吲哚唑烷和喹唑烷衍生物,并测试了其可能的多巴胺(DA)自受体活性。赤道吲哚izidine衍生物19e具有选择性自身受体激动剂的特征,活性是3-PPP的一半。但是,该化合物的拆分结果表明8R对映异构体是一种非选择性DA激动剂,其分布与(+)-3-PPP相似,而8S对映异构体是一种弱DA拮抗剂,没有任何DA激动剂活性。在6-OHDA损伤的大鼠中,不饱和喹oli嗪衍生物21也具有DA拮抗剂的特征,而轴向喹oli啶衍生物18a具有苯丙胺样的特征。所有其他衍生物均处于非活性状态。观察到的构效关系与现有的DA受体模型一致,
