Optimization of novel di-substituted cyclohexylbenzamide derivatives as potent 11β-HSD1 inhibitors

Novel 4,4-disubstituted cyclohexylbenzamide inhibitors of 11 beta-HSD1 were optimized to account for liabilities relating to in vitro pharmacokinetics, cytotoxicity and protein-related shifts in potency. A representative compound showing favorable in vivo pharmacokinetics was found to be an efficacious inhibitor of 11 beta-HSD1 in a rat pharmacodynamic model (ED(50) = 10 mg/kg).
