摘要:
A series of structurally simple 7-hydroxynaphthalenyl ureas and amides were discovered to be potent ligands of human vanilloid receptor I (VR1). 1-(7-Hydroxynaphthaten-1-yl)-3-(4-trifluoromethylbenzyl)urea 5f exhibited nanomolar binding affinity (K-i = 1.0 nM) and upon capsaicin challenge, behaved as a potent functional antagonist (IC50 = 4 nM). The synthesis and structure-activity relationships (SARs) for the series are described. (C) 2003 Elsevier Ltd. All rights reserved.
