[1-Oxo-2-halo(or hydrogen)indanyloxy(or thio)]-alkanoic acid products and salts, esters and amide derivatives where the indanyl ring may be further substituted with from 2 to 5 nuclear substituents. The [1-oxo-2-haloindanyloxy-(or thio)]alkanoic acids are prepared (1) via the halogenation of a [1-oxoindanyloxy(or thio)]alkanoic acid or (2) via the addition of halogen to a [1-oxoindenyloxy(or thio)]-alkanoic acid. The [1-oxoindanyloxy(or thio)]alkanoic acids are prepared (1) via cyclialkylation of a (2-alkylideneacyl)-phenoxy(or thio)alkanoic acid or (2) via etherification of a hydroxy(or mercapto)-2-alkyl-1-indanone. The [1-oxo-2-halo(or hydrogen)indanyloxy(or thio)]alkanoic acids are diuretics and saluretics. In addition, some of these compounds are also able to maintain the uric acid concentration in the body at pretreatment level or to cause a decrease in uric acid concentration.
[1-氧代-2-卤代(或氢)吲哚氧(或硫)基]-脂肪酸产物及其盐、酯和酰胺衍生物,其中吲哚环上可能进一步取代2-5个核取代基团。[1-氧代-2-卤代吲哚氧(或硫)基]-脂肪酸可通过以下方法制备:(1)将[1-氧代吲哚氧(或硫)基]-脂肪酸卤化或(2)将卤素添加到[1-氧代茚氧(或硫)基]-脂肪酸中。[1-氧代吲哚氧(或硫)基]-脂肪酸可通过以下方法制备:(1)将(2-烷基亚酰基)-苯氧(或硫)基脂肪酸環化或(2)将羟基(或巯基)-2-烷基-1-茚酮醚化。[1-氧代-2-卤代(或氢)吲哚氧(或硫)基]-脂肪酸具有利尿和盐利尿作用。此外,其中一些化合物还能够维持体内尿酸浓度在治疗前的水平或引起尿酸浓度下降。
