This invention relates to a novel class of compounds which are cysteine protease inhibitors, including but not limited to, inhibitors of Cathepsins K and L. These compounds are useful for treating diseases in which inhibition of bone resorption is indicated, such as osteoporosis.

cathepsin K. The kinetic data obtained showed that the increase of potency observed between different 1-cyanopyrrolidinyl inhibitors is due to an increase of k(on) values and that the association of the compound with the enzyme fits an apparent one-step mechanism. (13)C NMR experiments performed with the enzyme papain showed that compound 2 forms a covalent isothiourea ester adduct with the enzyme. As predicted
