Enone prodrugs of dopaminergic catecholamines represent a new type of prodrug in the research area of dopamine agonists. Here, we demonstrate the first benzo [g] quinoline- derived enone that induces potent dopamine agonist effects similar to aminotetralin-derived enones. Significant effects of (-)-4 were observed in microdialysis studies after administration of 1 nmol kg-1 sc and 3 nmol kg-1 po. With a potency comparable to that of ...
