Opis

General description

A cell-permeable, symmetrical bis(acylamino)ketone compound that acts as a potent, selective, reversible inhibitor of cathepsin K (K_i, = 22 nM). Also shown to inhibit cathepsin K in stably transfected CHO cells (IC₅₀ = 134 nM). Reported to bind to cathepsin K and span both the S- and S′- subsites. Inhibits papain (K_i >10 µM), trypsin (K_i >50 µM), and chymotrypsin (K_i >50 µM) only at higher concentrations. Exhibits greater selectivity for cysteine proteases of the papain family (K_i = 340 nM, 890 nM, and 1-3 µM for cathepsin L, cathepsin S, and cathepsin B, respectively).
