  Structure–affinity/activity relationships of 1,4-dioxa-spiro[4.5]decane based ligands at α<alpha>1 and 5-HT1A receptors

  摘要：

  Recently, 1-(1,4-dioxaspiro[4,5]dec-2-ylmethyl)-4-(2-methoxyphenyl)piperazine (1) was reported as a highly selective and potent 5-HT1AR ligand. In the present work we adopted an in-parallel synthetic strategy to rapidly explore a new set of arylpiperazine (7-32) that is structurally related to 1. The compounds were tested for binding affinity and functional activity at 5-HT1AR and alpha < alpha > 1-adrenoceptor subtypes and SAR studies were drawn. In particular, compounds 9, 27 and 30 emerged as promising alpha < alpha > 1 receptor antagonists, while compound 10 behaves as the most potent and efficacious agonist. All the compounds were docked into the 5-HT1AR theoretical model and the results were in agreement with the biological experimental data. These findings may represent a new starting point for developing more selective alpha < alpha > 1 or 5-HT1AR ligands. (C) 2014 Elsevier Masson SAS. All rights reserved.
