The invention concerns a diaryl ether cycloalkane of the formula I, or a pharmaceutically-acceptable salt thereof, ##STR1## wherein Ar.sup.1 is optionally substituted phenyl or naphthyl; X.sup.1 is oxy, thio, sulphinyl or sulphonyl; Ar.sup.2 is optionally substituted phenylene, or a 6-membered heterocyclene moiety containing up to three nitrogen atoms; R.sup.1 is (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 defines an optionally substituted ring having 4 to 7 ring atoms. The invention also concerns processes for the manufacture of a diaryl ether cycloalkane of the formula I, or a pharmaceutically-acceptable salt thereof, and pharmaceutical compositions containing said cycloalkane. The compounds of the invention are inhibitors of the enzyme 5-lipoxygenase.
该发明涉及一种化学式I的二芳基醚环烷烃,或其药用可接受的盐,其中Ar.sup.1是可选择取代的苯基或萘基;X.sup.1是氧、硫、亚砜或砜基;Ar.sup.2是可选择取代的苯基或含有最多三个氮原子的6元杂环烃基;R.sup.1是(1-6C)烷基,(3-6C)烯基,(3-6C)炔基,氰基(1-4C)烷基或(2-4C)酰基,或可选择取代的苯甲酰基;R.sup.2和R.sup.3共同形成一个(3-6C)烷基基团,其定义一个可选择取代的含有4至7个环原子的环。该发明还涉及一种制备化学式I的二芳基醚环烷烃或其药用可接受的盐的方法,以及含有所述环烷烃的药物组合物。该发明的化合物是5-脂氧合酶的抑制剂。
