    摘要： An epoxysuccinyl amino acid derivative of the formula ##STR1## wherein R.sup.1 is hydrogen, alkali metal, benzyl or cycloalkyl having 5 to 6 carbon atoms, R.sup.2 is alkyl having 3 to 4 carbon atoms, R.sup.3 is hydrogen, benzyloxycarbonyl, acetyl or benzoyl, and n is an integer of 2 to 7. The subject compounds exhibit inhibitory activity towards thiol protease, especially, calcium-activated neutral thiol protease which exists in excess in muscle tissues of mammals afflicted with muscular dystrophy.

    摘要翻译： 式中，R 1为氢，碱金属，苄基或碳原子数5〜6的环烷氧基烷基氨基酸衍生物，R2为碳原子数3〜4的烷基，R3为氢，苄氧羰基，乙酰基或苯甲酰基， n是2至7的整数。本发明化合物对于硫酸蛋白酶，特别是对于患有肌营养不良的哺乳动物的肌肉组织中存在过量的钙激活的中性硫醇蛋白酶表现出抑制活性。
