In an effort to develop potent antiinflammatory agents, a series of substituted chalcone derivatives was synthesized and evaluated for antiinflammatoryactivity through monitoring of their ability to inhibit xylene-induced ear edema in mice. Some of the tested compounds exhibited significant activity, and compounds 3f [(E)-1-(2,4-dihydroxyphenyl)-3-(4-dimethylamino)phenyl)prop-2-en-1-one] and 3h [
