Antiinflammatory and antioxidant evaluation of novel coumarin derivatives.

Several coumarin derivatives have been reported to present multiple biological activities and especially antiinflammatory/antioxidant activities. Recently the synthesis and in vivo/in vitro anti-inflammatory/antioxidant activities of several new coumarin derivatives with a 7-azomethine linkage have been reported. In the present study these derivatives were further tested for their antioxidant ability.
