200800161 、九、發明說明: 【本發明所屬之技術領域】 本發明係有關一種用以治療哺乳類對象之慢性阻塞性 肺疾之組成物,其包括有效量之特定雙環化合物。 【先前技術】 慢性阻塞性肺疾(C0PD)是一種特徵為不完全可逆性氣 流限制(airflow limitation)之疾病狀態。氣流限制通常 是進行性,而且與對肺有害的顆粒或氣體產生的異常發炎 ⑩反應相關。C0PD為一個綜合術語,其時常用以敘述兩種固 定型氣道疾病、慢性支氣管炎以及肺氣腫,但排除氣喘(可 逆性氣流限制)。 C0PD最重要的風險因子是抽香於。在許多國家中廣受 歡迎的煙斗、香善以及其他種類的於草吸用亦為C0PD的風 險因子。 C0PD其它起因包含職業性粉塵與化學品(蒸氣劑、刺 籲激劑以及煙),當曝露夠強或時間延長時,在通風差的住宅 内使用生質燃料烹調和加熱所造成的室内空氣污染或室外 空氣污染增加肺吸進顆粒的總負荷,雖然其在導致C0PD 上所扮演的具體角色未明。被動性的曝露於香菸煙霧中亦 會導致呼吸道症狀與C0PD。嬰幼兒期的呼吸道感染與成人 期的肺功能降低以及呼吸道症狀之增加相關(Global Initiative for Chronic Obstructive Lung Disease, POCKET GUIDE TO COPD DIAGNOSIS, MANAGEMENT, AND PREVENTION, A Guide for Health Care Professionals, 5 319029 200800161 UPDATED July, 2005)。 醫師表示目前的治療僅提供症狀舒緩,而因此 透過減緩肺功能之進行性流失或,更重要地,逆轉已建立b 之疾病本身,以改變C0PD發展的療法。然而,尚^有任合 ,種療法歸這些㈣擁成臨床效益。多㈣療 可 ^許多作时#!正《查。⑼,料仙製劑並不_ =滿足緩和或逆轉肺功能之進行性流失的主要未滿足之需 。前f腺素類(後文中稱為PG(S))為有機羧酸類別的成 2。亥(列腺素類係含括於人類或其他哺乳類的組織或器 吕中而且展不見的生理活性範圍。自然中發現的pGs(初 、、及PGs)通系具有如下式(a)中顯示的前列腺酸骨架: (α鏈)
