title: N-nitroso-bis(2-acetoxypropyl)amine as a further pancreatic carcinogen in Syrian golden hamsters.
abstract: N-Nitroso-bis(2-acetoxypropyl)amine, a possible beta metabolite of N-nitroso-di-n-propylamine, was shown to be a potent carcinogen in the Syrian golden hamster. After a single s.c. treatment, the pancreas was the most affected organ, followed by the liver, respiratory tract, and kidneys. However, repeated application resulted in a higher incidence of neoplasms of the respiratory tract than of the pancreas and kidneys. The effect of N-nitroso-bis(2-acetoxypropyl)amine on toxicity, target tissues, and carcinogenicity was similar to that of N-nitroso-bis(2-hydroxypropyl)amine. The assumption that these two compounds may have similar metabolic pathways was confirmed; N-nitroso-bis(2-acetoxypropyl)amine was readily deesterified to N-nitroso-bis(2-hydroxypropyl)amine in vivo and in vitro.
