The presence of cis-configured exchangeable ligands has long been considered a prerequisite for antitumor activity of platinum complexes, but over the past few years, several examples violating this structure-activity relationship have been recognized. We report here on studies with the
The genotoxic effects of N-nitroso-N-methylurea (MNU) and acetone oxime (ACOX) were tested in the Somatic Mutation and Recombination Test (SMART) in Drosophila melanogaster. We have performed the same assay on transgenic flies expressing the human gene encoding a glutathione S-transferase
The hepatocarcinogenicity of acetoxime has been tentatively linked with its metabolic oxidation to the potent genotoxicant and carcinogen propane 2-nitronate (P2-N). In order to test the hypothesis that acetoxime is metabolized to P2-N, the oxime (20 mM) was incubated with
The hepatocarcinogens 2-nitropropane and acetoxime have previously been found to induce a specific and qualitatively identical pattern of base damage in rat liver DNA and RNA, including the induction of increased levels of 8-hydroxyguanine. Because both 2-nitropropane and acetoxime are
We tested the ability of phenobarbital and two liver carcinogens, acetoxime and 1-nitroso-5,6-dihydrouracil (NDHU), to induce hyperplastic liver nodules (HLN) in MRC-Wistar and Wistar rats, using a system that included a single diethylnitrosamine (DEN) treatment, partial hepatectomy, and administration of
