The invention concerns a heterocyclic cycloalkane of the formula I ##STR1## wherein Q is an optionally substituted 6-membered monocyclic or 10-membered bicyclic heterocyclic moiety containing one or two nitrogen atoms; A is (1-6C)alkylene, (3-6C)alkenylene, (3-6C)alkynylene or cyclo(3-6C)alkylene; X is oxy, thio, sulphinyl, sulphonyl or imino; Ar is phenylene which may optionally bear one or two substituents or Ar is an optionally substituted 6-membered heterocyclene moiety containing up to three nitrogen atoms; R.sup.1 is hydrogen, (1-6C)alkyl, (3-6C)alkenyl, (3-6C)alkynyl, cyano-(1-4C)alkyl or (2-4C)alkanoyl, or optionally substituted benzoyl; and R.sup.2 and R.sup.3 together form a (3-6C)alkylene group which, together with the carbon atom to which R.sup.2 and R.sup.3 are attached, defines a ring having 4 to 7 ring atoms, and which ring may bear one or two substituents; or a pharmaceutically-acceptable salt thereof. The compounds of the invention are inhibitors of the enzyme 5-lipoxygenase.
该发明涉及一种异环脂环烷化合物,其化学式为I,其中Q是含有一个或两个氮原子的可选取代的6元单环或10元双环杂环基团;A是(1-6C)烷基,(3-6C)烯基,(3-6C)炔基或环(3-6C)烷基;X是氧,硫,亚砜基,砜基或亚胺基;Ar是苯基,可以选择性地带有一个或两个取代基,或Ar是含有最多三个氮原子的可选取代的6元杂环基团;R.sup.1是氢,(1-6C)烷基,(3-6C)烯基,(3-6C)炔基,氰基-(1-4C)烷基或(2-4C)酰基,或可选择性取代的苯甲酰基;而R.sup.2和R.sup.3一起形成一个(3-6C)烷基基团,与R.sup.2和R.sup.3连接的碳原子一起定义一个具有4到7个环原子的环,并且该环可能带有一个或两个取代基;或其药用可接受盐。该发明的化合物是5-脂氧合酶的抑制剂。
