1-aryl-4-[(1-tetralinyl)alkyl]piperazines: alkylamido and alkylamino derivatives. Synthesis, 5-HT1A receptor affinity, and selectivity. 3

J Med Chem. 1996 Aug 2;39(16):3195-202. doi: 10.1021/jm960087s.

Abstract

The synthesis and binding profile on 5-HT1A, 5-HT2, D-1, D-2, alpha 1, and alpha 2 receptors of the N-4 long-chain arylpiperazines 22-40 are reported, where an amino or amido function is inserted into the intermediate chain linked to the alpha position of the tetralin nucleus. Unlike the buspirone analogues, for the amido derivatives studied in this paper, the terminal amide function of long-chain piperazines is not important for 5-HT1A receptor affinity binding, and its removal yields high-affinity 5-HT1A receptor agents.
