In order to search for anti-inflammatory agents against autoimmune diseases, we synthesized 4-alkylthio-o-anisidine derivatives possessing antioxidant activity, and tested them for anti-inflammatory activity against the Arthus reaction in mice. Experimental inflammations, including the Arthus reaction, concanavalin A, phorbol ester and pyrophosphate-induced edemas in rats were inhibited by 4-propylthio-o-anisidine, which inhibited autoxidation of rat brain homogenate and suppressed the lipopolysaccharide-induced increase in the plasma malondialdehyde level in mice. An antioxidant may be an effective agent in immune complex type inflammation where active oxygen species play an important role.
为了寻找针对自身免疫疾病的抗炎药物,我们合成了具有抗氧化活性的4-烷基硫-o-氨基苯甲醚衍生物,并测试了它们对小鼠阿尔图斯反应的抗炎活性。实验表明,包括阿尔图斯反应、芒果糖蛋白A、佛波酯和焦磷酸诱导的大鼠水肿在内的实验性炎症都被4-丙基硫-o-氨基苯甲醚抑制,该化合物抑制了大鼠脑匀浆的自氧化,并抑制了小鼠血浆中脂多糖诱导的丙二醛水平升高。抗氧化剂可能在活性氧种类发挥重要作用的免疫复合物型炎症中是一种有效的药物。
