Uric acid in mammalian subjects is reduced and excretion of uric acid is increased by administering a compound of Formula I. 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. In Formula 1, x is 1 or 2: y is O, 1, 2 or 3; and R1 is selected from the group consisting of hydrogen, alkyl having 1 or 2 carbon atoms, hydroxy, alkoxy having 1 or 2 carbon atoms, fluoro, chloro, bromo, and amino. A is phenyl unsubstituted or substituted by one, two or three groups selected from the group consisting of halo, alkyl having 1 or 2 carbon atoms, perfluoromethyL alkoxy having 1 or 2 carbon atoms, and perfluoromethoxy; or cycloalkyl having from 3 to 6 ring atoms wherein the cycloalky! is unsubstituted or one one two ring carbons are independently mono-substituted by methyl or ethyl; or a 5 or 6 membered heleraromatic ring having 1 or 2 ring heteroatoms selected from N, S and O and the heteroaromatic ring is covalently bound to the remainder of the compound by a ring carbon.
通过给予化合物I,哺乳动物主体中的尿酸降低并且尿酸的排泄增加。该发明的化合物的降尿酸效果用于治疗或预防各种疾病,包括痛风、高尿酸血症、尿酸水平升高但不符合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、发生心血管疾病的风险、肿瘤溶解综合症、认知障碍、早发性原发性高血压和疟原虫引起的炎症。在公式1中,x为1或2:y为O,1,2或3;R1选自羟基、1或2个碳原子的烷基、1或2个碳原子的烷氧基、氟、氯、溴和氨基的群组;A是苯基,未取代或被一个、两个或三个来自卤族、1或2个碳原子的烷基、1或2个碳原子的全氟甲基烷氧基和全氟甲氧基的群组或有3到6个环原子的环烷基,其中环烷基未取代或一个或两个环碳原子单独被甲基或乙基单取代;或有1或2个来自N、S和O的环杂原子的5或6元杂环芳烃环,并且杂芳环通过一个环碳原子与化合物的其余部分共价结合。
