Genotoxicity of nitro musks in the micronucleus test with human lymphocytes in vitro and the human hepatoma cell line Hep G2

The nitro musk compounds musk xylene (1-tert.-butyl-3,5-dimethyl-2,4,6-trinitrobenzene), musk ketone (4-tert.-butyl-3,5-dinitro-2,6-dimethylacetophenone), musk ambrette (1-tert.-butyl-4-methyl-6-methoxy-3,5-dinitrobenzene), musk moskene (1,1,3,3,5-pentamethyl-4,6-dinitroindane) and musk tibetene (1-tert.-butyl-3,4,5-trimethyl-2,6-dinitrobenzene) were tested for their genotoxic activity in the micronucleus test (MN) with human lymphocytes in vitro and the human hepatoma cell line Hep G2. Compound concentrations were employed up to cytotoxic doses. Musk xylene, musk ketone, musk ambrette, musk moskene and musk tibetene revealed no genotoxicity in the micronucleus test with human lymphocytes and with the human hepatoma cell line Hep G2.
