title: N,N-disubstituted 2-aminotetralins are potent D-2 dopamine receptor agonists.
abstract: Mono- and di-N-substituted 2-amino-5-hydroxytetralins stimulate the D-2 dopamine receptor, 2-(N-n-propyl-N-phenylethylamino)-5-hydroxytetralin being the most potent D-2 agonist encountered to date. In contrast, 2-amino-5-hydroxytetralins only marginally stimulate the D-1 receptor; however, 2-(di-N-n-propylamino)-5, 6-dihydroxytetralin is equipotent with dopamine as a D-1 agonist. The results are discussed within the context of the two dopamine receptor hypothesis.
