The invention concerns a benzodioxole derivative of the formula I ##STR1## wherein Ar.sup.1 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; R.sup.1 is (1-6C)alkyl, (3-6C)alkenyl or (3-6C)alkynyl; and R.sup.2 and R.sup.3 together form a group of the formula --A.sup.1 --X--A.sup.2 -- which, together with the carbon atom to which A.sup.1 and A.sup.2 are attached, defines a ring having 5 to 7 ring atoms, wherein each of A.sup.1 and A.sup.2 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.
该发明涉及一种公式I的苯并二氧杂环衍生物,其中Ar1是一种可选取的取代的9-或10-成员双环杂环基,其中含有一个或两个氮杂原子,并且可选地含有从氮、氧和硫中选择的进一步杂原子;R1是(1-6C)烷基、(3-6C)烯基或(3-6C)炔基;R2和R3共同形成一个公式--A1--X--A2--的基团,其中与A1和A2连接的碳原子一起定义具有5到7个环原子的环,其中每个A1和A2是(1-3C)烷基,并且X是氧、硫、亚磺酰基或磺酰基,并且该环可能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-脂氧合酶抑制剂,可用于治疗炎症或过敏性疾病。
