Abstract :
A cloned human β3 adrenergic receptor assay was used to identify phenoxypropanolamine agonist 1. SAR studies led to the identification of benzenesulfonamide derivative 20, a 6.3 nM β3 agonist which shows 30-fold selectivity for β3 agonist activity over β1 and β2 receptor binding. Further refinement of this lead provided 4-bromo derivative 39, a subnanomolar agonist with 660-fold and 230-fold selectivity over β1 and β2, respectively.
