Abstract
The metabolism of 3 [carcinogenic] cyclic nitrosamines was studied in Sprague-Dawley rats. The compounds were nitrosopyrrolidine, nitrosohexamethyleneimine and nitrosoheptamethyleneimine and were labeled at the .alpha.-C with 14C. At low doses (2-4 mg/animal) the compounds were metabolized to 14CO2 to the extent of 77, 43 and 27%, respectively, after 24 h. At doses closer to the LD50 of the compounds (70-160 mg/animal) the metabolism values were only 14, 4 and 8%, respectively, after 24 h. The significance of these results is discussed.
