Metabolism of N -2-Fluorenylacetamide in X/Gf Mice: Lack of Correlation Between Biochemical Interaction and Carcinogenicity

Abstract
A comparative study of the metabolism of the carcinogen N-2-fluorenylacetamide by mice of the X/Gf strain (resistant to the tumorigenic action) and the NIH Swiss strain (susceptible to the tumorigenic action) showed slight but not outstanding differences in metabolic patterns. The activated metabolite N-hydroxy-N-2-fluorenylacetamide was excreted by both strains, and the levels of carcinogens or metabolites bound to liver macromolecular constituents were comparable in the X/Gf and NIH Swiss mice.
