title: A potent pancreatic carcinogen in Syrian hamsters: N-nitrosobis(2-oxopropyl)amine.
abstract: N-Nitrosobis(2-oxopropyl)amine (BOP), a further postulated beta-metabolite of di-n-propylnitrosamine, induced a high incidence of pancreatic duct adenomas and adenocarcinomas as early as 13 weeks in Syrian hamsters receiving weekly sc injections for life and a few pancreatic adenomas, after 28 weeks, in those given a single sc dose. Compared to related compounds, N-nitrosobis(2-hydroxypropyl)amine and N-nitrosobis(2-acetoxy-propyl)amine which are also pancreatic carcinogens, BOP induced only a few neoplasms of the lung, liver, and kidney and none in the nasal cavity, larynx, and trachea. The results therefore indicate progress in developing a more specific model for pancreatic carcinogenesis studies.
