描述

一般說明

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).

A cell-permeable, symmetrical bis(acylamino)ketone that acts as a potent, selective, and reversible inhibitor of cathepsin K (K_i,app = 22 nM). Shown to bind to cathepsin K and span both the S- and S′-subsites. A poor inhibitor of papain (K_i,app >10 µM) but displays greater selectivity towards other proteases of the papain family (K_i,app = 340 nM, 890 nM, and 1.3 µM for cathepsin L, cathepsin S, and cathepsin B respectively). Inhibits trypsin and chymotrypsin activities only at higher concentrations (K_i,app ≥ 50 µM).
