3-Substituted 1-benzothiophene-2-carboxanilides 2-5 and their corresponding sulfones 6-8 were synthesized. The antiinflammatory effect of compounds 2-8 was evaluated in tests of LTB4 biosynthesis, carrageenin edema and ear inflammation. With the exception of 3-hydroxyamides 5a-5c, low inhibitory activities against COX and LT biosynthesis were observed.
3-取代的1-苯并噻吩-2-羧酰苯胺类化合物2-5及其相应的磺酰化合物6-8被合成。在LTB4生物合成、卡拉胶水肿和耳部炎症测试中评估了化合物2-8的抗炎效果。除了3-羟基酰胺5a-5c之外,观察到对COX和LT生物合成的低抑制活性。
