ABSTRACT OF THE DISCLOSURE Alpha-aminoketone derivatives of the present invention strongly inhibit thiol protease such as papain, cathepsin B, cathepsin H, cathepsin L and calpain or the like and have excellent properties in absorbance on oral administration, tissue distribution and cell membrane permeability. The alpha- aminoketone derivatives can thus be used as therapeutic agents for treating muscular dystrophy, amyotrophy, cardiac infarction, stroke, Alzheimer's disease, disturbance of consciousness or dyskinesia caused upon brain trauma, multiple sclerosis, peripheral nervous neuropathy, cataract, inflammation, allergosis, fulminant hepatitis, osteoporosis, hypercalcemia, breast carcinoma, prostatic carcinoma or prostatomegaly. It may also be used as therapeutic agents for suppressing growth of cancer cells, preventing metastasis of cancer or suppressing aggregation of plaques.
