The epoxysuccinic acid derivatives of this invention are prepared by esterification of an epoxysuccinic acid or a halide thereof, by partial hydrolysis of an epoxysuccinic acid diester, by amidation of an epoxysuccinic acid monoester, or by hydrolysis of an epoxysuccinic acid amide monoester. These epoxysuccinic acid derivatives have excellent thiol protease inhibitory activity and anti-inflammatory activity without the acceleration of vascular permeability.
这项发明的环氧琥珀酸衍生物是通过环氧琥珀酸或其卤化物的酯化、环氧琥珀酸二酯的部分水解、环氧琥珀酸单酯的酰胺化,或环氧琥珀酸酰胺单酯的水解来制备的。这些环氧琥珀酸衍生物具有出色的巯基蛋白酶抑制活性和抗炎活性,而不会加速血管通透性。
