Die Erfindung betrifft die Verwendung von 2-(3,4-Dihydroxyphenyl)ethyl-substituierten Kohlensäurederivaten als Antioxidantien oder Radikalfänger, insbesondere die Verwendung zum Schutz von Zellen und Gewebe von Menschen vor den die Alterung beschleunigenden schädlichen Einflüssen von Radikalen und reaktiven Sauerstoffverbindungen. The use of 2-(3,4-dihydroxyphenyl)ethyl substituted carboxylic acid compounds (I) is claimed as antioxidants and radical traps. The use of 2-(3,4-dihydroxyphenyl)ethyl substituted carboxylic acid compounds of formula (I) is claimed as antioxidants and radical traps. R = H, lower alkyl, alkenyl, 1-oxyalkyl, 1-oxyalkenyl or OR ; R = H, lower alkyl, alkenyl, 1-oxyalkyl or 1-oxyalkenyl; X -X = O, S or NH, and R = 1-22C alkyl or cycloalkyl or 2-22C alkenyl or cycloalkenyl, (all optionally having at least one C atom replaced by O) or 7-15C substituted arylalkyl. Independent claims are also included for: (1) new compounds (I: X , X = NH; R = 1-22C alkyl or cycloalkyl or 2-22C alkenyl or cycloalkenyl), and (2) preparation of (I: (I: X , X = NH; R = 1-22C alkyl or cycloalkyl or 2-22C alkenyl or cycloalkenyl).
