An active oxygen inhibitor which contains an azole derivative represented by general formula (1) or a salt thereof as the active ingredient, wherein R¹ represents phenyl which may be substituted by 1 to 3 lower alkoxy groups or by a lower alkyleneoxy group, etc.; R² represents hydrogen, phenyl, halogen, lower alkoxycarbonyl, lower alkyl, lower aminoalkyl which may be substituted by lower alkyl, dihydrocarbostyrilyl, etc.; R³ represents the group (α), wherein R4B represents hydroxy, carboxy, lower alkenyl or lower alkyl, and m represents 0, 1 or 2; and X represents sulfur or oxygen.
A thiazole derivative which is excellent in an active oxygen inhibitory effect, represented by general formula (I), wherein R¹ represents phenyl which may be substituted by 1 to 3 lower alkoxy groups, and R² represents an optionally substituted pyridylcarbonyl group, a 5- to 15-membered mono-, di- or tricyclic heterocyclic group bearing 1 to 3 nitrogen, oxygen or sulfur atoms, or a substituted phenyl group.
