In the search for potent and selective human beta 3-adrenergic receptor (AR) agonists as potential drugs for the treatment of obesity and noninsulin-dependent (type II) diabetes a novel series of acetanilide-based analogues were prepared and their biological activities were evaluated at the human beta 3-, beta 2-, and beta 1-ARs. Among these compounds, 2-pyridylacetanilide (2f), pyrimidin-2-ylacetanilide (2u), and pyrazin-2-ylacetanilide (2v) derivatives exhibited potent agonistic activity at the beta 3-AR with functional selectivity over the beta 1- and beta 2-ARs. In particular, compound 2u was found to be the most potent and selective beta 3-AR agonist with an EC(50) value of 0.11 mu M and no agonistic activity for either the beta 1 - or beta 2-AR. In addition, 2f, 2u, and 2v showed significant hypoglycemic activity in a rodent diabetic model. (C) 2009 Elsevier Masson SAS. All rights reserved.
