Description

General description

A cell-permeable peptidyl bis-carbohydrazide compound that acts as a potent, selective, and reversible inhibitor of cathepsin K (K_i,app = 6 nM). Shown to completely block cathepsin K activity in primary human synovial fibroblast cultures at 1 µM. At higher concentrations, also inhibits the activities of cathepsin B and papain (K_i,app = 510 nM, 1.2 µM, respectively). Does not significantly inhibit cathepsin L.
