| pubmed-article:8676348 | pubmed:abstractText | A new analog of buspirone (1), i.e., 8-[4-[2-(1,2,3,4-tetrahydroisoquinolinyl)]butyl]-8-azaspiro- [4.5]decane-7,9-dione (6a), was synthesized. In was demonstrated that buspirone and its analog 6a were equipotent 5-HT(1A) ligands. Several behavioral models showed that 6a had essentially the same functional profile at 5-HT(1A) receptors as buspirone. The obtained results permit a conclusion that the basic nitrogen atom and terminal, bulky cycloimide moiety, but not the 2-pyrimidinyl group, of buspirone are directly involved in the formation of the bioactive complex with 5-Ht1A receptors. | lld:pubmed |
