A series of thiazole benzenesulfonamide-substituted 3-pyridylethanolamines was prepared and evaluated for their human beta(3) adrenergic receptor agonist activity. Incorporation of aryl and heteroaryl substitution in the 4-position of the thiazole ring resulted in a number of highly potent and selective beta(3) agonists. Results of preliminary in vivo evaluation of several of these compounds is described. (C) 2000 Elsevier Science Ltd. All rights reserved.
