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.

Receptor Agonist (BS148) with Selective Toxicity against Metastatic Melanoma
A new series of spirocyclic σ receptor (σR) ligands were prepared and studied. Most were found to have a high affinity and selectivity for σ1R; three compounds were shown to be σ1R agonists, while another proved to be the only σ1R antagonist. Only one of the σ1R agonists (BS148) also exhibited σ2R selectivity and was able to inhibit the growth of metastatic malignant melanoma cell lines without affecting
