Abstract
A first aspect of the invention relates to a compound of formula (I), or a pharmaceutically acceptable salt, hydrate, complex or pro-drug thereof, wherein: R3 is selected from cyclopentyl and cyclohexyl; R9 is a substituted 5 or 6-membered aryl or heteroaryl group or a 6,5- or 6,6-fused biaryl or heterobiaryl group. Compounds of formula (I) exhibit surprisingly high dual efficacies for human cathepsin S and K and are useful for the treatment of rheumatoid arthritis, osteoarthritis, chronic obstructive pulmonary disease (COPD), atherosclerosis, cardiovascular diseases which exhibit significant damage and remodeling of extracellular matrix (ECM) and chronic pain.
