title: Buspirone analogues as ligands of the 5-HT1A receptor. 1. The molecular structure of buspirone and its two analogues.
abstract: An interdisciplinary (X-ray, 1H and 13C NMR, IR, and theoretical quantum mechanical) study on the potent 5-HT1A receptor ligand buspirone (1) and its two structural analogues, mesmar (4,4-dimethyl-1-[4-[4-(2-quinolinyl)-1-piperazinyl]butyl]-2,6- piperidinedione) (2) and kaspar (8-[4-[4-(2-quinolinyl)-1-piperazinyl]butyl]-8-azaspiro[4.5]decane - 7,9-dione) (3), has been reported. The results have shown that buspirone-like molecules should appear in an extended rod-shape form, possessing several potential interaction sites with the receptor.
