of 5,6-dihydroxy-2-aminotetralins (6) were synthesized and their in vitro dopaminergicactivity was compared to that of (-)-DP-5,6-ADTN and the novel potent agonist Z12571. The results show that changing the cathecol ring for a heterocycle decreases the D1-like activity of the target molecules 6. However, the D2-like activity of tetrahydroquinoline (6j) was comparable to that of (-)-DP-5,6-ADTN.
