| pubmed-article:15546707 | pubmed:abstractText | 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 beta3-AR agonist (EC50=0.21 nM, IA=97%) with excellent selectivity for the beta3-AR over the beta1- and beta2-ARs (210- and 86-fold, respectively). | lld:pubmed |
