Ten-week-old, male, C57BL/6J mice are fed a diet containing 60% fat calories and water supplemented with 11% sucrose for 4 weeks. Groups (n=8) receive one of the following: Cort108297 (80?mg/kg QD), Cort108297 (40?mg/kg BID), Mifepristone (30?mg/kg BID), Rosiglitazone (10?mg/kg QD), or vehicle. Compared to mice receiving a high-fat, high-sugar diet plus vehicle, mice receiving a high-fat, high-sugar diet plus either Mifepristone or Cort108297 gain significantly less weight. At the end of the four week treatment period, mice receiving Cort108297 40?mg/kg BID or Cort108297 80?mg/kg QD also have significantly lower steady plasma glucose than mice receiving vehicle^[3]. Male rats are treated for five days with Mifepristone (10 mg/kg), Cort108297 (30 mg/kg and 60 mg/kg), Imipramine (10mg/kg) or vehicle and exposed to forced swim test (FST) or restraint stress. Both doses of Cort108297 potently suppress peak corticosterone responses to FST and restraint stress. However, only the higher dose of Cort108297 (60mg/kg) significantly decreases immobility in the forced swim test (FST) ^[4].
