C1- and C3-methyl-substituted derivatives of the potent dopamine (DA) receptor agonist 7-hydroxy-2-(di-n-propylamino)tetralin (7-OH-DPAT) have been synthesized, and their conformational preferences have been studied by use of NMR spectroscopy, X-ray crystallography, and molecular mechanics (MMP2) calculations. The compounds were tested for activity at central DA receptors, by use of biochemical and behavioral tests in rats. (1S,2R)-7-Hydroxy-1-methyl-2-(di-n-propylamino)tetralin [(+)-10] was demonstrated to be sevenfold less potent than (2R)-7-OH-DPAT as a DA receptor agonist. The other new compounds were of lower potency or inactive.
