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 = 9.7 nM). At higher concentrations, also inhibits the activities of cathepsin L, cathepsin B, and papain (K_i,app = 120 nM, 5.1 µM, and 2.3 µM, respectively). Completely blocks cathepsin K activity in primary human synovial fibroblast cultures at 1 µM.
