Indole derivatives represented by formula (I):
1
(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.
Indole 衍生物的化学式(I):1(其中所有符号在描述中有描述),以及制备该化合物的方法和作为活性成分的 DP 受体拮抗剂。由于化合物的化学式(I)与 DP 受体结合并具有拮抗作用,因此它们在预防和/或治疗疾病方面非常有用,例如过敏性疾病(过敏性鼻炎、过敏性结膜炎、特应性皮炎、支气管哮喘、食物过敏等)、全身肥大细胞增多症;由于全身肥大细胞激活引起的疾病、过敏性休克、支气管痉挛、荨麻疹、湿疹等)、伴有瘙痒的疾病(特应性皮炎、荨麻疹等)、由行为引起的继发性疾病(搔抓行为、殴打等)(白内障、视网膜脱离、炎症、感染、睡眠障碍等)、炎症、慢性阻塞性肺病、缺血再灌注障碍、脑血管障碍、风湿性关节炎并发的胸膜炎、溃疡性结肠炎等。
