Synthesis and biological evaluation of novel coumarin derivatives with a 7-azomethine linkage.
The synthesis of several novel coumarin derivatives with a 7-azomethine linkage was carried out starting from 7-formyl-coumarin. The compounds were tested in vivo for their anti-inflammatory activity and in vitro for their antioxidant ability. Compounds 3a and 3e possess significant protection against carrageenin induced rat paw edema.
