Compounds containing a 1,2,3-triazole-substituted benzenesulfonamide were p
repared and found to be potent and selective human beta(3)-adrenergic recep
tor agonists. The most interesting compound, trifluoromethylbenzyl analogue
12e (beta(3) EC50 = 3.1 nM with >1500-fold selectivity over binding to bot
h beta(1)- and beta(2) receptors), stimulates lipolysis in the rhesus monke
y (ED50 = 0.36 mg/kg) and is 25% orally bioavailable in the dog. (C) 2000 E
