title: Synthesis and pharmacology of the enantiomers of cis-7-hydroxy-3-methyl-2-(dipropylamino)tetralin.
abstract: The enantiomers of cis-7-hydroxy-3-methyl-2-(dipropylamino)tetralin (3) have been synthesized and evaluated for activity at central dopamine (DA), 5-hydroxytryptamine, and norepinephrine (NE) receptors, by use of biochemical and behavioral tests in rats. In addition, the affinities of the compounds for striatal [3H]spiroperidol and [3H]N-propylnorapomorphine binding sites were determined. The absolute configuration of the enantiomers was determined by X-ray diffraction of (+)-3. The pharmacological effects of both enantiomers are complicated, but (2R,3S)-7-hydroxy-3-methyl-2-(dipropylamino)tetralin [(-)-3] produced biochemical effects in vivo similar to those elicited by classical DA D2-receptor antagonists.
