MedChemExpress - Model L-006235 -294623-49-7

L-006235 (L-235) is a potent, selective, reversible and orally active inhibitor of cathepsin K, with an IC50 of 5 nM in bone resorption assay. L-006235 shows selectivity for cathepsin K (Ki=0.2 nM) over cathepsin B, cathepsin L, and cathepsin S (Ki=1, 6, and 47 μM, respectively). L-006235 can reduce collagen degradation and prevent bone loss[1][2].

Description：L-006235 (L-235) is a potent, selective, reversible and orally active inhibitor of cathepsin K, with an IC50 of 5 nM in bone resorption assay. L-006235 shows selectivity for cathepsin K (Ki=0.2 nM) over cathepsin B, cathepsin L, and cathepsin S (Ki=1, 6, and 47 μM, respectively). L-006235 can reduce collagen degradation and prevent bone loss.

In Vitro：L-006235 inhibits bone resorption in the rabbit bone resorption assay, with an IC50 of 5 nM[1]. L-006235 (10 μM; 1 h) show a punctate fluorescence throughout the cytoplasm in HepG2 cells[2].

In Vivo：L-006235 (0.6-15 mg/kg; p.o. qd for 8-11 d) reduces N-telopeptides (NTx) and creatinine (Cre) by up to 76% dose-dependently in rhesus monkey[1]. L-006235 (20 mg/kg; p.o.) exhibits high oral bioavailability (68%), long terminal half-life (204 min) and Cmax (1.4 μM) in rats[1].

IC50 & Target：Cathepsin B cathepsin K
