The uricosuric drug benzbromarone (3,5-dibromo-4-hydroxyphenyl)-1-(2-ethyl-3-benzofuranyl)methanone, a benzofurane derivative, was studied for its effects on parameters related to hepatic peroxisome proliferation. Groups of male F-344 rats were fed either basal diet, the peroxisome proliferator clofibrate at 5000 ppm as a comparison compound, or benzbromarone at two doses, 1000 and 2000 ppm. Benzbromarone and clofibrate produced hepatomegaly and increases in the activities of catalase, acyl CoA oxidase, malate dehydrogenase, and glycerol-3-phosphate dehydrogenase. Benzbromarone and clofibrate also both induced similar histologic and ultrastructural changes in hepatocytes, including induction of peroxisomes. Therefore, benzbromarone acted as a peroxisome-proliferating agent in rats under these conditions. Benzbromarone differs from other peroxisome proliferators in its chemical structure, uricosuric action, and the morphology of liver peroxisomes that were induced by exposure.
