/SPECIAL STUDIES/ ... Correlation analysis and inhibition studies with 7,8-benzoflavone and antibodies indicate that human cytochrome P-450 enzymes in the IA family are most effective in detoxicating /1,3-dinitropyrene/...; the contribution of cytochrome P-450PA (P-450 IA2, the phenacetin O-deethylase) is deemed more important, but a role for the small amount of cytochrome P1-450 (P-450 IA1) in the liver cannot be ruled out. In contrast to the case of 1,3-dinitropyrene, the inactivation of 1,6-dinitropyrene is well correlated with levels of cytochrome P-450NF (P-450 IIIA4, nifedipine oxidase) and its catalytic activities. The inactivation of 1,8-dinitropyrene was not correlated with any of the above parameters and only correlated with the conversion of benzo(a)pyrene to its 3-hydroxy and 4,5-dihydrodiol products, for which the principal enzymes involved in human liver are unknown. Thus, distinct human cytochrome P-450 enzymes are involved in the detoxication of different dinitropyrene congeners, and the situation appears to contrast with that in rat liver. /1,3-, 1,6-, and 1,8-dinitropyrene/
/SPECIAL STUDIES/ The ability of 1,6-dinitropyrene to induce chromosome damage in peripheral human lymphocyte cultures has been demonstrated. ... The fact that a positive result was obtained using human lymphocytes shows that, in the presence of the appropriate activation system, dinitropyrene is genotoxic in human cells. /1,6-dinitropyrene/
Novel desmutagenic substances and their production are disclosed. The desmutagenic substances are a fibrous food constituent separated from corn fibres. These substances inactivate mutagens such as nitroallene and food pyrolysate mutagens. They may be produced by removing starch, protein or other material from corn fibre by enzymic, chemical or physical treatment or a combination thereof.

A process is provided for the catalytic removal of polycyclic aromatic nitro, nitroso and/or amino compounds from the exhaust gas of a combustion system, in particular a diesel engine. The exhaust gas is brought into contact with a catalytic converter which includes a catalytically active material that contains titanium dioxide, at a temperature of from 150 to 600° C. The polycyclic aromatic compounds are oxidized at the catalytic converter through the use of oxygen to form nitrogen oxides, carbon dioxide and water.
