Arylpropanolamines: Selective β3 agonists arising from strategies to mitigate phase I metabolic transformations
摘要:
Utilization of N-substituted-4-hydroxy-3-methylsulfonanilidoethanolamines I as selective beta(3) agonists is complicated by their propensity to undergo metabolic oxidative N-dealkylation, generating 0.01-2% of a very potent alpha(1) adrenergic agonist 2. A summary of the SAR for this hepatic microsomal conversion precedes presentation of strategies to maintain the advantages of chemotype I while mitigating the consequences of N-dealkylation. This effort led to the identification of 4-hydroxy-3-methylsulfonanilidopropanolamines 15 for which the SAR for the unique stereochemical requirements for binding to the P adrenergic receptors culminated in the identification of the potent, selective 03 agonist 15f (c) 2007 Elsevier Ltd.

BMS-196085: A potent and selective full agonist of the human β3 adrenergic receptor
摘要:
A series of 4-hydroxy-3-methylsulfonanilido-1,2-diarylethylamines were prepared and evaluated for their human beta (3) adrenergic receptor agonist activity. SAR studies led to the identification of BMS-196085 (25), a potent beta (3) full agonist (K-i = 21 nM, 95% activation) with partial agonist (45%) activity at the beta (1) receptor. Based on its desirable in vitro and in vivo properties, BMS-196085 was chosen for clinical evaluation. (C) 2001 Elsevier Science Ltd. All rights reserved.
