Discovery of highly potent and selective biphenylacylsulfonamide-based β3-adrenergic receptor agonists and molecular modeling based on the solved X-ray structure of the β2-adrenergic receptor: Part 6

As an extension of research, we have investigated modification of left-hand side (LHS) of biphenyl analogues containing an acylsulfonamide moiety in the development of potent and selective human β3-adrenergic receptor (AR) agonists. Result of structure–activity relationships (SAR) and cassette-dosing evaluation in dogs showed that the hydroxynorephedrine analogue 16 had an excellent balance of in vitro and in vivo potency with pharmacokinetic profiles. In addition, to facilitate structure-based drug design (SBDD), we also have performed a docking study of biphenyl analogues based on the X-ray structure of the β2-adrenergic receptor.
