[Microbial mutagenicity testing of N-nitrosoiminostilbene and N-nitrosoiminodibenzyl, the nitrosation products of the drugs carbamazepine and trimipramine hydrochloride].
The active agents of the drugs Finlepsin and Herphonal, carbamazepine and trimipramine, were nitrosated under simulated human gastric conditions. For both formed N-nitroso compounds, N-nitroso iminostilbene (N-nitroso-5H-dibenz(b,f)azepine) and N-nitroso iminodibenzyl (N-nitroso-10,11-dihydro-5H-dibenz(b,f)azepine), tests for mutagenic potency in the Ames-test gave negative results.
