Potent benzimidazolone based human β3-adrenergic receptor agonists

Synthesis of unsymmetrical 1,3-substituted-1,3-dihydro-benzimidazolones via copper-catalyzed C–N coupling under visible light

Although photoinduced copper catalysis for carbon–nitrogen (C–N) amine bond formation with alkyl/aryl halides has been developed, the potential of copper photocatalysis for the synthesis of 1,3-substituted benzimidazolones remains mostly unexplored.

Potent oxindole based human β3 adrenergic receptor agonists

The synthesis and biological evaluation of a series of oxindole beta(3) adrenergic receptor agonists is described. A modulation of rat atrial tachycardia was observed with substitution at the 3-position of the oxindole moiety.

Discovery of potent and orally bioavailable heterocycle-based β3-adrenergic receptor agonists, potential therapeutics for the treatment of obesity

A novel series of heterocycle-based analogs were prepared and evaluated for their in vitro and in vivo biological activity as human beta(3)-adrenergic receptor (AR) agonists. Several analogs demonstrated potent agonist activity at the beta(3)-AR, functional selectivity against beta(1)- and beta(2)-ARs, and favorable pharmacokinetic profiles in vivo. Compound 17 increased oxygen consumption in rats, a measure of energy expenditure, with an ED(20%) of 2mg/kg.
