This invention provides a series of novel cyclic amides of formula I in which the group >Z--Y--X< is selected from >C.dbd.CH--N<, >N-CH.dbd.CH<, >C.dbd.N--N< and >N--N.dbd.C< and the other radicals have the meanings defined in the following specification. The compounds of formula I are leukotriene antagonists. The invention also provides pharmaceutically acceptable salts of the formula I compounds; pharmaceutical compositions containing the formula I compound, or their salts, for use in the treatment of, for example, allergic or inflammatory diseases, or endotoxic or traumatic shock conditions; and processs for the manufacture of the formula I compounds, as well as intermediates for use in such manufacture.
该发明提供了一系列新颖的公式I的环酰胺,其中基团>Z--Y--X<选择自>C.dbd.CH--N<、N-CH.dbd.CH<、C.dbd.N--N<和N--N.dbd.C<,其他基团的含义在以下说明中定义。公式I化合物是
白三烯拮抗剂。该发明还提供了公式I化合物的药学上可接受的盐;含有公式I化合物或其盐的药物组合物,用于治疗例如过敏性或炎症性疾病,或内毒素性或创伤性休克症状;以及用于制造公式I化合物的方法,以及用于该制造的中间体。
