Description

一种治疗痛风的化合物 技术领域
本发明涉及一种治疗痛风的化合物。。
背景技术
痛风是嘌呤代谢异常致使尿酸合成增加而导致的代谢性疾病。肾功能异常时由于肾脏的尿酸清除率下降也会引起尿酸水平上升。血浆中的尿酸达到饱和,导致尿酸单钠结晶沉积在远端关节周围相对缺乏血管的组织中。这种结晶的出现可导致单关节或者多关节的急性炎性滑膜炎。痛风在男性中较为多见,拇趾是最常见的受累区域,50%~70%初次发病发生于此。90%的痛风患者在其一生中的某个时期会发生第一跖趾关节受累。其他可能受累的足部区域有足背部、足跟以及踝部。除了累及关节之外,尿酸结晶还可以沉积在皮下,被称作痛风结节。
研发一种能够有效治疗痛风的新药,显得尤为重要。
发明内容
本发明的目的在于提供一种治疗痛风化合物。
