Trimetoquinol (TMQ, 1) is a unique catecholamine with a strong stereodependence for agonism at beta-adrenergic (S much greater than R) and antagonism at thromboxane A(2)/prostaglandin H-2 (TP; R much greater than S) receptors. Our laboratory has reported the effects of N-alkylation and modification of the trisubstituted benzyl group in these receptor systems. For iodinated derivative 5, maintaining potency in TP receptor systems (112%) was coupled with maintaining limited potency in beta-adrenergic receptor systems (34% for beta(1) and 47% for beta(2)) In this study, several diverse TMQ derivatives were prepared to probe for binding interactions specific to a particular receptor system. Planar amidine 2, which was designed to explore the importance of TMQ's chiral center, showed a dramatic loss of potency (<1%) in each receptor system. Likewise, the homologation of a previously described N-benzyl derivative (3) to the N-phenylethyl derivative 4 also showed reduced potency (<3%) in both receptor systems. However, modification of the trimethoxybenzyl group of TMQ to a 4-hydroxy-3-nitrobenzyl group (7) provided a unique lead for TMQ derivatives with significant potency in TP receptor systems (91%) and reduced potency in beta-adrenergic receptor systems (4% for beta(1) and 19% for beta(2)).

analogs. Interestingly, removal of the 4'-substituent of 3',5'-diiodo analogs increased beta 2-AR affinity with little or no effect on beta 1-AR and TP binding. Thus, analog 21a displayed highlypotent (pKi 9.52) and selective (beta 2/beta 1 = 600) binding affinity for beta 2-AR. On the other hand, trifluoromethyl substituents at the 3'- and 5'-positions (27) essentially abolished binding affinity at beta

Fused piperidine substituted arylsulfonamides are .beta..sub.3 adrenergic receptor agonists with very little .beta..sub.1 and .beta..sub.2 adrenergic receptor activity and as such the compounds are capable of increasing lipolysis and energy expenditure in cells. The compounds thus have potent activity in the treatment of Type II diabetes and obesity. The compounds can also be used to lower triglyceride levels and cholesterol levels or raise high density lipoprotein levels or to decrease gut motility. In addition, the compounds can be used to reduced neurogenic inflammation or as antidepressant agents. Compositions and methods for the use of the compounds in the treatment of diabetes and obesity and for lowering triglyceride levels and cholesterol levels or raising high density lipoprotein levels or for decreasing gut motility are also disclosed.
