Antagonist of the androgen receptor in rats
Vinclozolin is a dicarboximide fungicide widely used in Europe and the United States for control of diseases caused by B. cinerea, S. sclerotiorum, and Monilinia species in grapes, fruits, vegetables, ornamental plants, and turfgrass.1 Metabolites of vinclozolin, M1 and M2, are effective antagonists of the androgen receptor in rats exhibiting Ki values of 92 and 9.7 µM respectively.2 In fathead minnow, M1 and M2 failed to compete for high-
