5-di-tert-butyl-4-hydroxybenzylidene)pyrrolidin-2-ones was synthesized and evaluated as candidate antiinflammatory/analgesic agents as well as dual inhibitors of prostaglandin and leukotriene synthesis. Some compounds that showed dual inhibitory activity were found to possess equipotent antiinflammatoryactivities to indomethacin, with reduced ulcerogenic effects.

3-(3,5-di-tert-butyl-4-hydroxy-benzylidene)-2-pyrrolidone and N-substituted derivatives thereof are described. The substituent includes alkyl, alkoxy, alkynyl phenyl-alkylene, hydroxy-alkylene and amino-alkylene. They are effective as an anti-inflammatory, analgesic and antithermic agent, and they have a low toxicity.
