Abstract

The metabolism of four xenobiotics, pentachloromethylthiobenzene, 2 chloro-n-isopropylacetanilide, 2-acetamido-4- (chloromethyl) thiazole and 2,4',5-trichlorobiphenyl, which are known to be metabolized via the mercapturic acid pathway, was examined in germfree and conventional rats. An essential role for the intestinal flora in the metabolism of the above compounds and in the production of certain metabolites was established. Mechanisms for the formation of these latter metabolites from the mercapturates are proposed. These mechanisms involve enterohepatic circulation and metabolism by the intestinal flora. The significance of xenobiotic metabolism by the intestinal microflora is discussed.
