ABSTRACT:
Indole derivatives represented by formula (I):(wherein all symbols are described in the description), a process for the preparation of the same and a DP receptor antagonist comprising it as an active ingredient. Since the compounds of formula (I) binds to and are antagonistic to a DP receptor, they are useful in for the prevention and/or treatment of diseases, for example, allergic diseases (allergic rhinitis, allergic conjunctivitis, atopic dermatitis, bronchial asthma, food allergy, etc., systemic mastocytosis; disorders due to systemic mastocyte activation, anaphylactic shock, bronchoconstriction, urticaria, eczema, etc.), diseases accompanied with itching (atopic dermatitis, urticaria, etc.), secondary diseases caused by behaviors (scratching behaviors, beating, etc.) (cataract, retinal detachment, inflammation, infection, sleep disorder, etc.), inflammation, chronic obstructive pulmonary disease, ischemic reperfusion disorder, cerebrovascular disorder, pleuritis complicated by rheumatoid arthritis, ulcerative colitis, and the like.
