A potent, selective, orally active inhibitor of cathepsin K with Ki of 0.1 nM, 0.049 nM and 0.85 nM for human, rabbit and rat cathepsin K, respectively; shows less or no potentcy for human cathepsin S/L/B/C (Ki=0.83/1.7/32/2500 nM); inhibits human osteoclasts bone resorption in vitro at a concentration more than 100 fold lower than that of alendronate; reduces plasma calcium level increased by PTHrP in thyroparathyroidectomized rats, decreases serum and urine C-telopeptide of type I collagen level. Osteoporosis Phase 2 Discontinued
