N-[2-(2,4-Difluorophenoxy)trifluoromethyl-3-pyridyl]sulfonamide derivatives 3—6 were prepared by the reaction of 3-pyridylamines and sulfonyl chlorides. Inhibitory activities of these compounds toward secretory phospholipase A₂ (sPLA₂) were examined and N-[2-(2,4-difluorophenoxy)-5-trifluoromethyl-3-pyridyl]-2-naphthalenesulfonamide (5c) was found to be the most potent against sPLA₂ with an IC₅₀ value of 90 μM.
