Bioactivity | L-873724 is a potent, orally bioavailable, selective and reversible[2] non-basic cathepsin K inhibitor, with IC50s of 0.2, 178, 264, and 5239 nM for cathepsin K, cathepsin S, cathepsin L, cathepsin B, respectively[1]. L-873724 also exhibits an IC50 of 0.5 nM for rabbit cathepsin K. L-873724 inhibits bone resorption[2]. |
Target | IC50: 0.2 nM (Cathepsin K), 178 nM (Cathepsin S), 264 nM (Cathepsin B), 5239 nM (Cathepsin B), 0.5 nM (Rabbit cathepsin K) |
