This invention relates to novel heterocyclic compounds structurally characterized by containing a specific heterocyclic group and by the presence of --CH.sub.2 --S-- directly bound to the specific heterocyclic group. These heterocyclic compounds are useful as medicines, particularly as antagonists of SRS-A (slow reacting substance of anaphylaxis).
本发明涉及新型
杂环化合物,其结构特征是含有特定的杂环基团,并且与特定的杂环基团直接相连的是--CH.sub.2--S--。这些
杂环化合物可用作药物,特别是作为SRS-A(过敏反应的缓慢反应物质)拮抗剂。
