3-hydroxybenzo[b]thiophene-2-sulfide derivatives have been prepared by ring closure of an appropriately substituted 2--R.sup.1 SCH.sub.2 S-- benzoic acid ester in the presence of a strong base. These compounds have been found to be specific inhibitors of 5-lipoxygenase and thereby useful in the treatment of inflammation, pain and fever associated with inflammation, arthritic conditions, asthma, allergic disorders such as allergic rhinitis and chronic bronchitis, skin diseases like psoriasis and atopic exzema, cardiovascular or vascular disorders, and other leukotriene mediated diseases. Furthermore, these compounds have been found to exhibit cytoprotective activity which does not involve the inhibition of gastric acid secretion but can be used at relatively low dosages for increasing the resistance of gastro-intestinal mucosa to strong irritants.

生物是通过在强碱存在下环合适当取代的2- R.sup.1 SCH.sub.2 S-
苯甲酸酯制备而成。这些化合物已被发现是5-脂氧合酶的特异性
抑制剂,因此可用于治疗与炎症相关的疼痛和发热,关节炎,哮喘,过敏性疾病如过敏性鼻炎和慢性支气管炎,皮肤病如
银屑病和特应性皮炎,心血管或血管疾病以及其他
白三烯介导的疾病。此外,这些化合物已被发现表现出细胞保护作用,其不涉及胃酸分泌的抑制,但可用于以相对较低的剂量增加胃肠黏膜对强刺激物的抵抗力。
