4-dioxo-5-(2-naphthylmethylene)-3-thiazolidineacetic acids and 2-thioxo analogues have been prepared as aldose reductase inhibitors. In vitro inhibitory activities of bovine lens aldose reductase were determined by a conventional method. 1-Naphthyl-substituted derivatives of the 2-thioxo series were the more potent inhibitors (IC50 congruent with 10 nM) with similar activity to that of Epalrestat.
