Abstract
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. Ris hydrogen, methyl or ethyl and Ris hydrogen or methyl, or Ris hydroxy and Ris hydrogen, or Ris O and Ris absent, or Rand Rtogether are —CHCH—. Ris hydrogen or alkyl having from 1 to 3 carbon atoms. One of Rand Ris alkyl having from 1 to 3 carbon atoms, and the other is hydrogen or alkyl having from 1 to 3 carbon atoms. Ris 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(R) wherein Ris 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.
