A novel class of human beta(3)-adrenergic receptor agonists was designed in effort to improve selectivity and metabolic stability versus previous disclosed beta(3)-AR agonists. As observed, many of the beta(3)-AR agonists seem to need the acyclic ethanolamine core for agonist activity. We have synthesized derivatives that constrained this moiety by introduction of a pyrrolidine. This unique modification maintains human beta(3) functional potency with improved selectivity versus ancillary targets and also eliminates the possibility of the same oxidative metabolites formed from cleavage of the N-C bond of the ethanolamine. Compound 39 exhibited excellent functional beta(3) agonist potency across species with good pharmacokinetic properties in rat, dog, and rhesus monkeys. Early de-risking of this novel pyrrolidine core (44) via full AMES study supports further research into various new beta(3)-AR agonists containing the pyrrolidine moiety. (C) 2011 Elsevier Ltd.
