Pharmacophoric mapping based on 3D-QSAR studies is performed on sixteen cyclic ureidobenzenesulfonamides for their beta(3)-adrenergic receptor agonistic activity. The best 3D-QSAR model (with r(2)=0.877) which described the properties and distributions of 5-biophoric and 2-secondary biophoric sites, showed a good correlation between the observed and predicted activity both in training and test.

Human beta3 adrenergic receptor agonists containing 5-membered ring ureas were shown to be potent partial agonists with excellent selectivity over beta1 and beta2 binding. L-760,087 (4a) and L-764,646 (5a) (beta3 EC50 = 18 and 14 nM, respectively) stimulate lipolysis in rhesus monkeys (ED50 = 0.2 and 0.1 mg/kg, respectively) with minimal effects on heart rate. Oral absorption in dogs is improved over other urea analogs.

The cyclopentylpropylimidazolidinone L-766,892 is a potent beta3 AR agonist (EC50 5.7 nM, 64% activation) with 420- and 130-fold selectivity over binding to the beta1 and beta2 ARs, respectively. In anesthetized rhesus monkeys, L-766,892 elicited dose-dependent hyperglycerolemia (ED50 0.1 mg/kg) with minimal effects on heart rate.
