Human β3 adrenergic receptor agonists containing cyclic ureidobenzenesulfonamides
摘要:
Human beta(3) adrenergic receptor agonists containing 5-membered ring ureas were shown to be potent partial agonists with excellent selectivity over beta(1) and beta(2) binding. L-760,087 (4a) and L-764,646 (5a) (beta(3) 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. (C) 1999 Elsevier Science Ltd. All rights reserved.
