A novel anti-active-oxygen agent which inhibits the generation of active oxygen species, is highly safe, can be preparated at a rather low cost, and contains an amino acid derivative represented by general formula (I) or a salt thereof as the active ingredient, wherein Ar represents 2-hydroxyphenyl, 2-hdyroxyl-1-naphthyl or pyridyl provided that the aromatic rings of these groups may be substituted by halogen, alkyl, hydroxy, hydroxyalkyl, nitro, alkoxy or carboxy; R represents the side chain of an amino acid; X represents -CH₂-NH- or -CH=N-; Y represents hydrogen, -COOR¹, -SO₃H, -CON(R²)R³, -CONHCH(R⁵)COOR⁴ or -CH₂OH, wherein R¹ to R⁴ represent each hydrogen or alkyl, and R⁵ represents the side chain of an amino acid; and n represents an integer of 0 or 1.
一种新型抗活性氧制剂,可抑制活性氧的生成,安全性高,制备成本低,含有通式(I)代表的氨基酸衍生物或其盐作为活性成分,其中Ar代表2-羟基苯基、2-羟基-1-萘基或吡啶基,但这些基团的芳环可被卤素、烷基、羟基、羟烷基、硝基、烷氧基或羧基取代;R 代表氨基酸的侧链; X 代表-CH₂-NH-或-CH=N-;Y 代表氢、-COOR¹、-SO₃H、-CON(R²)R³、-CONHCH(R⁵)COOR⁴ 或 -CH₂OH,其中 R¹ 至 R⁴ 分别代表氢或烷基,R⁵ 代表氨基酸的侧链;以及 n 代表 0 或 1 的整数。
