The invention relates to compounds of the formula ##STR1## wherein R is hydrogen or lower alkyl, Z is alkylene of 1 to 10 carbon atoms, --(C*H.sub.2).sub.3 --C.tbd.C--, --C*H.sub.2 --C.tbd.C--(CH.sub.2).sub.3 --, and --(CH.sub.2).sub.2 O].sub.n (CH.sub.2).sub.2 -- wherein n is an integer of 1 to 3, the carbon atom marked with an asterisk is linked to the phenoxy moiety, and salts thereof with pharmaceutically acceptable bases. The compounds of formula I are antagonists of slow reacting substance of anaphylaxis (SRS-A; leukotrienes C.sub.4, D.sub.4 and E.sub.4), which renders them useful as agents for the treatment of allergic conditions.
该发明涉及以下式的化合物##STR1##其中R是氢或较低的烷基,Z是1至10个碳原子的烷基,--(C*H.sub.2).sub.3 --C.tbd.C--, --C*H.sub.2 --C.tbd.C--(CH.sub.2).sub.3 --,以及--(CH.sub.2).sub.2 O].sub.n (CH.sub.2).sub.2 --其中n是1至3的整数,带有星号标记的碳原子与苯氧基团连接,并且其与药学上可接受的碱盐。式I的化合物是过敏反应缓慢反应物(SRS-A;白三烯C.sub.4,D.sub.4和E.sub.4)的拮抗剂,使它们在过敏症状治疗剂方面有用。
