[On the carcinogenetic action of N-nitroso compounds. 7th communication: methyl-, trideuteromethyl-, ethyl-, n-propyl-, n-butyl-, acetoxymethyl-nitrosamine, and methyl-butyroxymethyl-nitrosamine (author's transl)].

The homologons alkyl-acetoxymethyl-nitrosamines were tested for carcinogenicity in SD rats. All compounds were found to be carcinogenic and induced within the same time carcinomas of the forestomach. The total doses necessary for induction of tumors are related to the length of the alkyl chain and hence to the watersolubility. These results are discussed.
