  Tryptamine-based human β3-adrenergic receptor agonists. Part 1: SAR studies of the 7-position of the indole ring

  摘要：

  A series of tryptamine-based 2-thiophenesulfonamide derivatives were prepared and their agonistic activity for the beta-adrenergic receptors (ARs) was evaluated. Compound 54, containing 7-methanesulfonyloxy tryptamine, was found to be a highly potent beta(3)-AR agonist (EC50 = 0.21 nM, IA = 97%) with excellent selectivity for the beta(3)-AR over the beta(1)- and beta(2)-ARs (210- and 86-fold, respectively).

  The continued SAR investigation of tryptamine-based human beta(3)-adrenergic receptor (AR) agonists is reported. Prior efforts resulted in the identification of 2 as a potent beta(3)-AR agonist. Further modification of the left side arylsulfonamide portion in 2 provided compounds with good cell permeability, which have potent agonistic activity for beta(3)-AR. Cinnamylamine analog 16i exhibited an excellent agonistic profile in vitro and good oral bioavailability in rats. (C) 2004 Elsevier Ltd. All rights reserved.

  A series of tryptamine derivatives with modified sulfonamide were designed, synthesized, and evaluated for their ability to stimulate CAMP accumulation in CHO cells expressing the cloned human beta(3)-adrenergic receptor (AR). For this series of compounds, our objective was to symmetrize the a-position of the tryptamine moiety maintaining its activity and reducing the cost of production. Compound 11h, having m-aminobenzene, exhibited excellent agonistic activity for beta(3)-AR with excellent subtype selectivity. (C) 2004 Elsevier Ltd. All rights reserved.
