Carlson GP: Effect of trichlorophenols on xenobiotic metabolism in the rat. Toxicology. 1978 Oct;11(2):145-51.
Unlike halogenated benzenes, trichlorophenols did not induce xenobiotic metabolism in the rat. 2,3,5-, 2,3,6-, 2,4,5-, and 2,4,6-Trichlorophenol at doses as high as 400 mg/kg p.o. daily for 14 days did not alter EPN detoxification. Only 2,4,5-trichlorophenol at the highest dose decreased microsomal NADPH-cytochrome c reductase activity and cytochrome P-450 content. In vitro, all 4 isomers inhibited EPN detoxification and the demethylation of p-nitroanisole. UDP-glucuronyltransferase was not altered in vivo and was only slightly inhibited in vitro by 2,3,5- and 2,4,5-trichlorophenol. The compounds were not hepatotoxic as assessed by measurement of hepatic glucose-6-phosphatase and serum sorbitol dehydrogenase. |
