Novel heterocyclic compounds shown by the general formula ##STR1## or the pharmaceutically acceptable salts thereof useful as medicament in particular as antagonist of slow reacting substance of anaphylaxis (SRS-A).
摘要:
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).

摘要:
Novel phenylene derivatives shown by the general formula ##STR1## where A represents a hydrogen atom, a phenyl group or a phenoxy group, n represents an integer of 3 to 10, R.sub.1 represents a hydrogen atom or a lower alkoxy group, X.sub.1 represents --CH.sub.2 CH.sub.2 --, --CH.dbd.CH--, --CONH--, B represents ##STR2## wherein R.sub.2 represents a hydrogen atom, a halogen atom, a nitro group, etc.), ##STR3## (wherein R.sub.3 represents a hydrogen atom, a hydroxyl group or a lower alkoxy group), X.sub.2 represents --CH.dbd.CH--, --CH.sub.2 CH.sub.2 --, etc. and D represents a carboxy group, a lower alkoxycarbonyl group or ##STR4## which are useful as drugs, particularly SRS-A(slow reacting substance of anaphylaxis) antagonist, i.e. they are useful as prophylaxis and treatment for various allergic diseases (e.g. bronchial asthma, allergic rhinitis, urticaria) or, ischemic heart diseases, inflammation, etc. induced by SRS-A.
