Uric acid in mammalian subjects is reduced and excretion of uric acid is increased by administering a compound of Formula I or a pharmaceutically acceptable salt thereof.
In Formula I m is 0, 1, 2, 3 or 4; n is 0 or 1; m+n is not more than 4;
t is 0 or 1; q is 0 or 1; and r is 0, 1 or 2. R6 is hydrogen, methyl or ethyl and R12 is hydrogen or methyl, or R6 is hydroxy and R12 is hydrogen, or R6 is O and R12 is absent, or R6 and R12 together are —CH2CH2—. R7 is hydrogen or alkyl having from 1 to 3 carbon atoms. One of R8 and R9 is alkyl having from 1 to 3 carbon atoms, and the other is hydrogen or alkyl having from 1 to 3 carbon atoms. R10 is hydrogen, halo, alkyl having from 1 to 3 carbon atoms or alkoxy having from 1 to 3 carbon atoms. X is C(O) and r is 0 and t is 0; or X is NH(R11) wherein R11 is hydrogen or alkyl having from 1 to 3 carbon atoms. A is phenyl, unsubstituted or substituted by 1 or 2 groups selected from halo, hydroxy, methyl, ethyl, perfluoromethyl, methoxy, ethoxy, and perfluoromethoxy; or a 5 or 6 membered heteroaromatic 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 of Formula I by a ring carbon; or cycloalkyl having from 3 to 6 ring carbon atoms wherein the cycloalkyl is unsubstituted or one or two ring carbons are independently monosubstituted by methyl or ethyl. The uric acid-lowering effects of the Compounds of Formula I 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, and cognitive impairment.
在哺乳动物主体中,通过给予公式I或其药学上可接受的盐,可以降低尿酸并增加尿酸的排泄。在公式I中,m为0、1、2、3或4;n为0或1;m+n不超过4;t为0或1;q为0或1;r为0、1或2。R6为氢、甲基或乙基,R12为氢或甲基,或R6为羟基且R12为氢,或R6为O且R12不存在,或R6和R12一起为-CH2CH2-。R7为氢或具有1至3个碳原子的烷基。R8和R9中的一个为具有1至3个碳原子的烷基,另一个为氢或具有1至3个碳原子的烷基。R10为氢、卤素、具有1至3个碳原子的烷基或具有1至3个碳原子的烷氧基。X为C(O),r为0且t为0;或X为NH(R11),其中R11为氢或具有1至3个碳原子的烷基。A为苯基,未取代或被1或2个选自卤素、羟基、甲基、乙基、全氟甲基、甲氧基、乙氧基和全氟甲氧基的基团取代;或具有1或2个选自N、S和O的杂环芳香环的5或6个成员,且杂环芳香环通过一个环碳原子与公式I的余下部分共价结合;或具有从3到6个环碳原子的环烷基,其中环烷基未取代或一个或两个环碳原子分别被甲基或乙基单取代。公式I化合物的降低尿酸作用可用于治疗或预防多种疾病,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、肿瘤溶解综合征和认知障碍。
