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.
N-[2-(2,4-二氟苯氧基)三氟甲基-3-吡啶基]磺酰胺衍生物3-6是通过3-吡啶胺与磺酰氯的反应制备的。这些化合物对分泌型磷脂酶A2(sPLA2)的抑制活性进行了研究,发现N-[2-(2,4-二氟苯氧基)-5-三氟甲基-3-吡啶基]-2-萘磺酰胺(5c)对sPLA2的抑制作用最强,其IC50值为90μM。
