R-(−)-N-alkyl-11-hydroxy-10-hydroxymethyl- and 10-methyl-aporphines as 5-HT1A receptor ligands
摘要:
Several N-substituted-11-hydroxy-10-hydroxymethyl- and 11-hydroxy-10-methylaporphines were synthesized and their binding affinities at dopamine D, and D, receptors and serotonin 5-HT1A and 5-HT2A receptors in rat forebrain tissue were evaluated. Tested compounds displayed moderate to high affinity to 5-HT1A receptors but low affinity to D, and D-2 receptors. The most potent novel 5-HT1A agent was R-(-)-N-methyl-10-hydroxymethyl-11-hydroxyaporphine. (c) 2007 Elsevier Ltd. All rights reserved.

(R)-11-Hydroxyaporphine (2) and (R)-11-hydroxy-10-methylaporphine (3) were synthesized from natural morphine by using new, short, and efficient synthetic sequences. The dopaminergic and serotonergic effects of 2 and 3 were evaluated by use of in vitro and in vivo test systems. The results indicate that 3 is a potent, selective, and efficacious 6-HT1A receptor agonist. In contrast, 2 is a partial 5-HT1A receptor agonist of low potency which has affinity also for central D-1 and D-2A receptors. The differences in pharmacological profiles were rationalized by modeling of ligand-receptor interactions using homology-based receptor models of the 6-HT1A and D-2A receptor binding site. The selective and pronounced serotonergic effects of 3 appear to be due to the CIO-methyl group, which is accommodated by a lipophilic pocket in the 5-HT1A receptor. In contrast, the C10-methyl group of 3 is not accommodated by the binding site model of the D-2A receptor.
