In the present work a series of novel coumarin-3-carboxamides and their hybrids with the alpha-lipoic acid were designed, synthesized and tested as potent antioxidant and anti-inflammatory agents. The new compounds were evaluated for their antioxidant activity, their activity to inhibit in vitro lipoxygenase and their in vivo anti-inflammatory activity. In general, the derivatives were generally found to present antioxidant and anti-inflammatory activities. Discussion is made based on the results for the structure-activity relationships in order to define the structural features required for activity.
