Cyclic amine sulfonamides as linkers in the design and synthesis of novel human beta(3) adrenergic receptor agonists.

Piperidine, pyrrolidine, and azetidine sulfonamides were examined as linkers in designing novel human beta(3) adrenergic receptor (beta(3)-AR) agonists. The azetidine derivative 37, and piperidine derivatives 7, 8, and 13 were found to be potent beta(3)-AR agonists and have good selectivity against beta(1)- and beta(2)-AR.

Novel substituted 4-aminomethylpiperidines as potent and selective human beta3-agonists. Part 2: arylethanolaminomethylpiperidines.

The synthesis and SAR of a series of beta3 adrenoreceptor agonists based on a novel template derived from 4-aminomethylpiperidine coupled with a common pharmacophore, arylethylamine, is described. This combination led to the identification of human beta3 adrenoreceptor agonists with in vivo activity in a transgenic mouse model.

Novel substituted 4-aminomethylpiperidines as potent and selective human beta3-agonists. Part 1: aryloxypropanolaminomethylpiperidines.

The synthesis and SAR of a series of human beta3 adrenoreceptor agonists based on a template derived from a common pharmacophore coupled with 4-aminomethylpiperidine is described. Potent and selective agents were identified such as 26 that was in vitro active in CHO cells expressing human beta3-AR (EC50=49 nM, IA=1.1), and in vivo active in a transgenic mouse model.

4-Aminopiperidine ureas as potent selective agonists of the human beta(3)-adrenergic receptor.

The preparation and structure-activity relationships (SARs) of potent agonists of the human beta(3)-adrenergic receptor (AR) derived from a 4-aminopiperidine scaffold are described. Examples combine human beta(3)-AR potency with selectivity over human beta(1)-AR and/or human beta(2)-AR agonism. Compound 29s was identified as a potent (EC(50)=1nM) and selective (greater than 400-fold over beta(1)- with no beta(2)-AR agonism) full beta(3)-AR agonist with in vivo activity in a transgenic mouse model of thermogenesis.

Novel (4-piperidin-1-yl)-phenyl sulfonamides as potent and selective human beta(3) agonists.

A series of novel (4-piperidin-1-yl)-phenyl sulfonamides was prepared and evaluated for their biological activity on the human beta(3)-adrenergic receptor (AR). Replacement of the 3,4-dihydroxyl group of the catechol moiety with 4-hydroxyl-3-methyl sulfonamide on the left-hand side of the compounds resulted in a number of potent full agonists at the beta(3) receptor. Modification of the right-hand side of the compounds by incorporation of a free carboxylic acid resulted in a few potent human beta(3) agonists with low affinities for beta(1)- and beta(2)-ARs.
