Isolated rat hepatocytes were incubated with approximately equimolar amounts of N-nitrosodi-n-propylamine (NDPA) and N-nitrosodiallylamine (NDAA) in order to compare their metabolism. The principal metabolite of NDPA was N-nitroso-(2-hydroxypropyl)propylamine, which was present as a glucuronide. N-Nitroso-(3-hydroxypropyl)propylamine and N-nitrosopropyl-(carboxyethyl)amine were minor metabolites;

Ten carcinogenic N-nitroso compounds were assayed for DNA-damaging activity in primary cultures of human and rat hepatocytes. DNA fragmentation was measured by the alkaline elution technique, and unscheduled DNA synthesis by quantitative autoradiography. Positive dose-related responses in the range of
