Thiazolyl and isothiazolyl azomethine derivatives with anti-inflammatory and antioxidant activities.
Several thiazolyl/benzothiazolyl/benzo[d]isothiazolyl Schiff bases and hydrazones have been tested as anti-inflammatory agents and five new compounds have been synthesized. The anti-inflammatory activity was examined in vivo using the carrageenin induced mice paw edema test (inhibition 16.3-64%). The compounds were tested for antioxidant activity as hydroxyl scavengers and for their ability to interact with the stable free radical 1,1-diphenyl-2-picryl-hydrazyl (DPPH). Both anti-inflammatory and antioxidant activities depended on some structural characteristics of the synthesized compounds.
