Uric acid in mammalian subjects is reduced and excretion of uric acid is increased by administering a compound of Formula (I) or its pharmaceutically acceptable salts. The uric acid-lowering effects of the compounds of this invention are used to treat or prevent a variety of conditions including gout, hyperuricemia, elevated levels of uric acid that do not meet the levels customarily justifying a diagnosis of hyperuricemia, renal dysfunction, kidney stones, cardiovascular disease, risk for developing cardiovascular disease, tumor-lysis syndrome, cognitive impairment, early-onset essential hypertension, and Plasmodium falciparum-induced inflammation. R1 is hydrogen or alkyl having from 1 to 3 carbon atoms. R2 is alkyl having from 1 to 3 carbon atoms, alkoxy having from 1 to 3 carbon atoms, hydroxy, nitro, halo, thio, alkylthio, or cyano. R3 and R4 are each independently hydrogen, methyl, ethyl, perfluoromethyl, methoxy, ethoxy, perfluoromethoxy, halo, hydroxy, nitro, or amino.
在哺乳动物体内,通过给予公式(I)或其药学上可接受的盐的化合物,可以减少尿酸并增加尿酸的排泄。该发明化合物的降尿酸作用可用于治疗或预防各种疾病,包括痛风、高尿酸血症、尿酸水平升高但不达到通常诊断为高尿酸血症的水平、肾功能障碍、肾结石、心血管疾病、患心血管疾病的风险、肿瘤溶解综合征、认知障碍、早发性高血压和疟原虫引起的炎症。其中R1为氢或有1至3个碳原子的烷基。R2为有1至3个碳原子的烷基、有1至3个碳原子的烷氧基、羟基、硝基、卤素、硫、烷硫基或氰基。R3和R4各自独立地为氢、甲基、乙基、全氟甲基、甲氧基、乙氧基、全氟甲氧基、卤素、羟基、硝基或氨基。
