  Dopamine D₃ Receptor Antagonists. 1. Synthesis and Structure−Activity Relationships of 5,6-Dimethoxy-N-alkyl- and N-Alkylaryl-Substituted 2-Aminoindans

  摘要：

  5,6-Dimethoxy-2-(N-dipropyl)-aminoindan (3, PNU-99194A) was found to be a selective dopamine D-3 receptor antagonist with potential antipsychotic properties in animal models. To investigate the effects of nitrogen substitution on structure-activity relationships, a series of 5,6-dimethoxy-N-alkyl- and N-alkylaryl-substituted 2-aminoindans were synthesized and evaluated in vitro for binding affinity and metabolic stability. The results indicate that substitution at the amine nitrogen of the 2-aminoindans is fairly limited to the di-N-propyl group in order to achieve selective D-3 antagonists. Thus, combinations of various alkyl groups were generally inactive at the D-3 receptor. Although substitution with an N-alkylaryl or N-alkylheteroaryl group yields compounds with potent D-3 binding affinity, the D-2 affinity is also enhanced, resulting in a less than 4-fold preference for the D-3 receptor site, and no improvements in metabolic stability were noted. A large-scale synthesis of the D-3 antagonist 3 has been developed that has proven to be reproducible with few purification steps. The improvements include the use of 3,4-dimethoxybenzaldehyde as a low-cost starting material to provide the desired 5,6-dimethoxy-1-indanone 5c in good overall yield (65%) and the formation of a soluble silyl oxime 17 that was reduced efficiently with BH3. Me2S. The resulting amino alcohol was alkylated and then deoxygenated using a Lewis acid and Et3SiH to give the desired product 3 in good overall yield of (similar to 65%) from the indanone 5c.
