Description

[0001] field of invention [0002] The invention belongs to the field of medicine. The present invention relates to a class of compounds and pharmaceutical compositions thereof for treating or preventing cathepsin-dependent disorders. These compounds and compositions containing these compounds can be used as bone resorption inhibitors to treat related diseases. Background technique [0003] Osteoporosis is a common and frequently-occurring disease among the elderly, especially menopausal and postmenopausal women. With the changes in the spectrum of contemporary diseases, WHO has listed osteoporosis as one of the three major diseases of middle-aged and elderly people, ranking seventh among common diseases. About 50% of women and 20% of men over the age of 50 suffer a fracture caused by osteoporosis. At present, the common drugs for osteoporosis include anti-resorptive drugs, drugs that promote bone formation, dual-action drugs of the former two, biological drugs or other dru...
