    Characterization of WY 14,643 and its complex with Aldose reductase
    (Nature Publishing Group, 2016) Sawaya, M.R.; Verma, M.; Balendiran, V.; Rath, N.P.; Cascio, D.; Balendiran, G.K.
    The peroxisome proliferator, WY 14,643 exhibits a pure non-competitive inhibition pattern in the aldehyde reduction and in alcohol oxidation activities of human Aldose reductase (hAR). Fluorescence emission measurements of the equilibrium dissociation constants, Kd, of oxidized (hAR? NADP+) and reduced (hAR? NADPH) holoenzyme complexes display a 2-fold difference between them. Kd values for the dissociation of WY 14,643 from the oxidized (hAR? NADP+ ? WY 14,643) and reduced (hAR? NADPH? WY 14,643) ternary complexes are comparable to each other. The ternary complex structure of hAR? NADP+ ? WY 14,643 reveals the first structural evidence of a fibrate class drug binding to hAR. These observations demonstrate how fibrate molecules such as WY 14,643, besides being valued as agonists for PPAR, also inhibit hAR. ? The Author(s) 2016.
