摘要:
Starting from (1S,2R)-5-methoxy-1-methyl-2-N,N-dipropylaminotetralin [(+)-UH-232] as a lead structure, a series of novel 6-substituted 2-aminotetralins have been discovered which show high affinity for dopamine D-3 receptors. One compound, GR218231, exhibits ca. 400 fold selectivity for the dopamine D-3 receptor over the D-2 receptor and ca. 10,000 fold selectivity with respect to D-1 and D-4 receptors.
