The invention concerns a cyclic ether derivative of the formula I, ##STR1## wherein Ar.sup.1 is optionally substituted phenyl or naphthyl; A.sup.1 is (1-6C)alkylene, (3-6C)alkenylene, (3-6C)alkynylene or cyclo(3-6C)alkylene; Ar.sup.2 is optionally substituted phenylene, or a 6 membered heterocyclene moiety containing up to three nitrogen atoms; R.sup.1 and R.sup.2 together form a group of the formula --A.sup.2 --X--A.sup.3 -- wherein each of A.sup.2 and A.sup.3 is (1-6C)alkylene and X is oxy, thio, sulphinyl, sulphonyl or imino; and R.sup.3 is (1-6C)alkyl, (2-6C)alkenyl, (2-6C)alkynyl or substituted (1-4C)alkyl; or a pharmaceutically-acceptable salt thereof. The compounds of the invention are inhibitors of the enzyme 5-lipoxygenase.
该发明涉及公式I的环醚衍生物,其中Ar.sup.1是可选择取代的苯基或萘基;A.sup.1是(1-6C)烷基,(3-6C)烯基,(3-6C)炔基或环(3-6C)烷基;Ar.sup.2是可选择取代的苯基,或含有最多三个氮原子的6元杂环基;R.sup.1和R.sup.2共同形成公式--A.sup.2--X--A.sup.3--的基团,其中A.sup.2和A.sup.3中的每一个是(1-6C)烷基,X是氧,硫,亚硫酰基,磺酰基或亚胺基;R.sup.3是(1-6C)烷基,(2-6C)烯基,(2-6C)炔基或取代的(1-4C)烷基;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。
