Prousis, Maria Koufaki, Giorgos Athanasellis, Georgia Melagraki, Antreas Afantitis, Olga Igglessi-Markopoulou, Christos Kontogiorgis, Dimitra J. Hadjipavlou-LitinaA series of N-substituted-quinolinone-3-aminoamides and their hybrids containing the α-lipoic acid
functionality were designed and synthesized as potential bifunctional agents combining antioxidant and
anti-inflammatory activity. The new compounds were evaluated for their antioxidant activity and for their
ability to inhibit in vitro lipoxygenase as well as for their anti-inflammatory activity in vivo. In general, the
derivatives were found to be potent antioxidant or anti-inflammatory agents. The results are discussed in
terms of structure−activity relationships and an attempt is made to define the structural features required
for activity.
