A series of azepanone inhibitors of cathepsinS is described. Selectivity over both cathepsin K and cathepsinL was achieved by varying the P2 substituent. Ultimately, a balanced potency and selectivity profile was achieved in compound 39 possessing a 1-methylcyclohexyl alanine at P2 and nicotinamide as the P′ substituent. The cellular potency of selected analogs is also described.
