Synthesis of Azetidin-2-One Derivatives as Inhibitor of Secretory Phospholipase A2 with Anti-Inflammatory Activity

The title compounds have been synthesized and tested for structure activity relationship for Phospholipase A2 (PLA2) [E.C. 3.1.1.4] enzyme inhibition. The in vitro PLA2 enzyme inhibitory activity of azetidin-2-one derivatives and in vivo anti-inflammatory activity studies using mice are highlighted. The results show that some azetidin-2-one derivatives are very good PLA2 inhibitors and can also be used as antiinflammatory drugs.
