ABSTRACT:
A series of novel 3-mono(substituted methyl)- and 3,3-di(substituted methyl)-2-oxo-indoline-1-alkanoic acid compounds have been prepared, including their lower alkyl esters and unsubstituted amide derivatives, as well as the base salts of said acids with pharmacologically acceptable cations. These compounds are useful in therapy as aldose reductase inhibitors for the control of certain chronic diabetic complications. Typical members include those compounds derived from 2-oxo-indoline-1-acetic acid wherein a 3,4-dichlorobenzyl or 3,4-dichloro-.alpha.-methylbenzyl moiety is substituted at 3-position of the molecule. Preferred member compounds include 3-(3,4-dichlorobenzyl)-2-oxo-indoline-1-acetic acid, 5-chloro-3-(3,4-dichlorobenzyl)-2-oxo-indoline-1-acetic acid, 3-(3,4-dichlorobenzyl)-6-methoxy-2-oxo-indoline-1-acetic acid, 3-(3,4-dichlorobenzyl)-6-hydroxy-2-oxo-indoline-1-acetic acid and 3-(3,4-dichloro-.alpha.-methylbenzyl)-2-oxo-indoline-1-acetic acid. Methods for preparing these compounds from known starting materials are provided.
