3-hydroxybenzo[b]thiophene -2- sulfide derivatives of formula:
or a pharmaceutically acceptable salt thereof are disclosed wherein
R' and R independently are, e.g., H, loweralkyl, phenyl or substituted phenyl, heteroaryl or substituted heteroaryl, or loweralkylcarbonyl;
n is 0, 1 or 2;
X1 X2, X3 and X4 independently are H, loweralkyl, haloloweralkyl or loweralkenyl.
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, skin diseases, 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. A process for preparing those compounds is also disclosed.
式中的 3-羟基苯并[b]噻吩-2-硫醚衍生物:
或其药学上可接受的盐,其中
R'和 R 独立地为 H、低级烷基、苯基或取代苯基、杂芳基或取代杂芳基或低级烷基羰基;
n 为 0、1 或 2;
X1、X2、X3 和 X4 独立地是 H、低级烷基、卤代低级烷基或低级烯基。
已发现这些化合物是 5-脂氧合酶的特异性抑制剂,因此可用于治疗与炎症、关节炎、哮喘、过敏性疾病、皮肤病、心血管疾病和其他白三烯介导的疾病有关的炎症、疼痛和发热。此外,还发现这些化合物具有细胞保护活性,这种活性不涉及抑制胃酸分泌,但可以相对较低的剂量用于增强胃肠道粘膜对强刺激物的抵抗力。此外,还公开了制备这些化合物的工艺。
