The present invention relates to an amide derivative of the formula (1), having a C5a receptor antagonistic action
wherein each symbol is as defined in the specification.
The above-mentioned amide derivative, an optically active form thereof and a pharmaceutically acceptable salt thereof are promising as an agent for the treatment or prophylaxis of diseases or syndromes caused by inflammation caused by C5a [e.g., autoimmune diseases such as rheumatism, systemic lupus erythematosus and the like, sepsis, adult respiratory distress syndrome, chronic obstructive pulmonary disease, allergic diseases such as asthma and the like, atherosclerosis, cardiac infarction, brain infarction, psoriasis, Alzheimer's disease and serious organ injury (e.g., pneumonia, nephritis, hepatitis and pancreatitis and the like) due to activation of leukocytes caused by ischemia reperfusion, trauma, burn, surgical invasion and the like]. Moreover, they are useful as a therapeutic or prophylactic agent for the infectious diseases caused by bacteria and virus that invade via a C5a receptor.
本发明涉及一种式(1)的酰胺衍生物,具有C5a受体拮抗作用,其中每个符号如规范中所定义。上述酰胺衍生物及其光学活性形式和药学上可接受的盐被认为是治疗或预防由C5a引起的炎症所致疾病或综合症的药物,例如自身免疫性疾病,如风湿病,系统性红斑狼疮等,败血症,成人呼吸窘迫综合症,慢性阻塞性肺疾病,过敏性疾病,如哮喘等,动脉硬化,心脏梗塞,脑梗塞,牛皮癣,阿尔茨海默病和严重器官损伤(例如,肺炎,肾炎,肝炎,胰腺炎等),由缺血再灌注,创伤,烧伤,手术侵袭等引起的白细胞激活所致。此外,它们还可用作通过C5a受体侵入的细菌和病毒引起的传染病的治疗或预防剂。
