Abstract
A new series of 3-aryl-2-hydroxyquinoline-4-carboxylic acids 17a,b, 2-aryl-3-hydroxyquinoline-4-carboxylic acids 12a–d and their derivatives 13–16 and 18–21 were designed, synthesized and evaluated for their antioxidant activity using the ABTS assay method. Compounds 14 and 21a,b showed good antioxidant activity, whereas the remaining compounds displayed mild to moderate activity. All compounds were characterized by physical and spectral data.
