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.

Homologation of the Alkyl Side Chain of Antimitotic Phenyl 4-(2-Oxo-3-alkylimidazolidin-1-yl)benzenesulfonate Prodrugs Selectively Targeting CYP1A1-Expressing Breast Cancers Improves Their Stability in Rodent Liver Microsomes
Phenyl 4-(2-oxo-3-alkylimidazolidin-1-yl)benzenesulfonates (PAIB-SOs) are a new family of antimitotic prodrugs bioactivated in breast cancer cells expressing CYP1A1. In this study, we report that the 14C-labeled prototypical PAIB-SO [14C]CEU-818 and its antimitotic counterpart [14C]CEU-602 are distributed in whole mouse body and they show a short half-life in mice. To circumvent this limitation, we
