    摘要: The invention relates an epoxysuccinamide derivative represented by the general formula (1) ##STR1## wherein R.sup.1 and R.sup.2 are the same or different from each other and independently represent H or an aromatic hydrocarbon group or aralkyl group which may be substituted, or R.sup.1 and R.sup.2 may form a nitrogen-containing heterocyclic ring together with the adjacent nitrogen atoms, R.sup.3 is H or an acyl group, R.sup.4 is H or an aralkyl group, and R.sup.5 is an aromatic hydrocarbon group or aralkyl group which may be substituted, or R.sup.5 may form an amino acid residue, which may be protected, together with the adjacent nitrogen atom, or a salt thereof, and a medicine comprising the derivative as an active ingredient; and this compound has an inhibiting activity against cathepsin, and particularly, specifically inhibits cathepsin L and is hence useful for prevention and treatment of osteopathy such as osteoporosis.
