title: Influence of 5-[2-(N,N-dimethylamino)ethoxy]-7-oxo-7H-benzo(C)fluorene hydrochloride (benflurone) on the activity of rat liver aspartate and alanine aminotransferases.
abstract: The influence of repeated s.c. administration of the cytostatic 5-[2-(N,N-dimethylamino)ethoxy]-7-oxo-7H-benzo(c)fluorene hydrochloride (benflurone, 25 mg/kg body weight daily) on the activities of aspartate and alanine aminotransferases (AST, ALT) per g of tissue, and protein concentration in the liver of adult male rats was studied. During the first week of benflurone administration, the activities of ALT and AST decreased by 2/3 and 1/3, respectively, in comparison with controls while the protein concentration did not show any substantial change. No in vitro influence of benflurone on AST and ALT was found even at the highest concentration tested (10(-4) M). The significance of the aminotransferase decrease after treatment with benflurone and possible participation of these changes in the side- or cytostatic effects of the compound are considered.
