Synthesis and SAR of benzyl and phenoxymethylene oxadiazole benzenesulfonamides as selective β3 adrenergic receptor agonist antiobesity agents
摘要:
Benzyl and phenoxymethylene substituted oxadiazoles are potent and orally bioavailable beta(3) adrenergic receptor (AR) agonists. The 4-trifluormethoxy substituted 5-benzyl oxadiazole 5f has an EC50 of 8 nM in the beta(3) AR agonist assay with 100-fold selectivity over beta(1) and beta(2) AR binding inhibition activity. Its oral bioavailability in dogs is 30 +/- 4%, with a half-life of 3.8 +/- 0.4 h. In the anesthetized rhesus, 5f evoked a dose-dependent glycerolemia (ED50Gly = 0.15 mg/kg): Under these conditions a heart rate increase of 15% was observed at a dose level of 10 mg/kg.
