The invention concerns a benzodioxole derivative of the formula I
wherein Ar1 is an optionally substituted 9- or 10-membered bicyclic heterocyclic moiety containing one or two nitrogen heteroatoms and optionally containing a further heteroatom selected from nitrogen, oxygen and sulphur ;
R1 is (1-6C)alkyl, (3-6C)alkenyl or (3-6C)alkynyl ; and
R2 and R3 together form a group of the formula -A1-X-A2- which, together with the carbon atom to which A1 and A2 are attached, defines a ring having 5 to 7 ring atoms, wherein each of A1 and A2 is (1-3C)alkylene and X is oxy, thio, sulphinyl or sulphonyl, and which ring may bear one or two substituents ;
or a pharmaceutically-acceptable salt thereof ;
which compounds are inhibitors of 5-lipoxygenase and are useful in the treatment of inflammatory or allergic disease.
本发明涉及一种式 I 的苯并二恶茂衍生物
其中 Ar1 是任选取代的 9 或 10 元双环杂环分子,含有一个或两个氮杂原子,并任选含有选自氮、氧和硫的另一个杂原子;
R1 是 (1-6C)烷基、(3-6C)烯基或 (3-6C)炔基;以及
R2 和 R3 共同形成一个式 -A1-X-A2- 的基团,该基团与 A1 和 A2 所连接的碳原子一起,定义了一个具有 5 至 7 个环原子的环,其中 A1 和 A2 均为 (1-3C)亚烷基,X 为氧基、硫代、亚砜基或磺酰基,该环可带有一个或两个取代基;
或其药学上可接受的盐;
这些化合物是 5-脂氧合酶的抑制剂,可用于治疗炎症或过敏性疾病。
