[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.
Ethacrynicacid (EA) is a glutathione-s-transferase pi (GSTP1-1) inhibitor. Fifteen of EA analogues were designed and synthesized and their inhibition on GSTP1-1 activity was tested in lysate of human leukemia HL-60 cells. These compounds were synthesized using substituted phenol as precursors through reacting with 2-chlorocarboxylic acid and acylation. Structure-activity analysis indicates that replacements
