L 006235 is a reversible and potent cathepsin K inhibitor that displays more than a 4000 fold selectivity over cathepsins B, L and S. L-006,235 is a highly effective and orally available inhibitor of cathepsin K, a key enzyme involved in bone resorption. With a Ki(app) value of 0.2 nM, it demonstrates remarkable selectivity for cathepsin K over cathepsins B, -L, and -S, with Ki(app) values of 1 µM, 6 µM, and 47 µM, respectively.
