    • PURPOSE: New epoxysuccinamide derivatives or its salt and a medicament containing them are provided which have a specific inhibitory activity against cathepsin L and cathepsin L family enzymes and thus are useful as, e.g., preventive drugs for diseases of bone metabolism such as osteoporosis, hypercalcemia and so on. CONSTITUTION: Epoxysuccinamide derivatives represented by general formula (I) or salts thereof; processes for the preparation of them; and drugs containing the same as the active ingredient are described. In formula, R1 is hydrogen, alkyl or aminoalkyl and R2 is optionally substituted aminoalkyl, optionally substituted aryl, an optionally substituted heterocyclic group, optionally substituted aralkyl or alkyl substituted with an optionally substituted heterocyclic group, or alternatively R1 and R2 together with the nitrogen atom adjacent thereto may form an optionally substituted nitrogenous heterocycle; and R3 and R4 are each independently hydrogen, alkyl or aralkyl. These compounds exhibit a specific inhibitory activity against cathepsin L and cathepsin L family enzymes and thus are useful as, e.g., preventive drugs for diseases of bone metabolism such as osteoporosis, hypercalcemia and so on.
    • 目的:提供新的环氧琥珀酰胺衍生物或其盐和含有它们的药物,其对组织蛋白酶L和组织蛋白酶L家族酶具有特异性抑制活性,因此可用于例如骨代谢疾病如骨质疏松症,高钙血症和 所以。 构成:由通式(I)表示的环氧琥珀酰胺衍生物或其盐; 它们的制备过程; 并描述含有与活性成分相同的药物。 在式中,R 1为氢,烷基或氨基烷基,R 2为任选取代的氨基烷基,任选取代的芳基,任选取代的杂环基,任选取代的芳烷基或被任选取代的杂环基取代的烷基,或者R1和R2与氮原子一起 与其相邻可以形成任选取代的含氮杂环; 且R 3和R 4各自独立地为氢,烷基或芳烷基。 这些化合物对组织蛋白酶L和组织蛋白酶L家族酶具有特异性抑制活性,因此可用作例如骨代谢疾病如骨质疏松症,高钙血症等的预防药物。
