چکیده

Cyclopenta(cd)pyrene, a constituent of environmental emissions, has been found to mutate and transform mammalian cells in culture. Cyclopenta(cd)pyrene 3,4-oxide, a presumed metabolite, was found to be a direct-acting mutagen and to transform mammalian cells. These results suggest that cyclopenta(cd)pyrene 3,4-oxide may be an ultimate mutagenic form of the parent hydrocarbon.

Metabolic activation of cyclopenta(cd)pyrene to 3,4-epoxycyclopenta(cd)pyrene by rat liver microsomes.

Cyclopenta(cd)pyrene (CPP), a polycyclic aromatic hydrocarbon without a bay region, is a potent bacterial mutagen. The experiments reported in this paper demonstrate that the major CPP metabolite generated by liver microsomes prepared from either phenobarbital or 3-methylcholanthrene pretreated rats is the optically active trans-3,4-dihydroxy-3,4-dihydrocyclopenta(cd)pyrene. Other experiments i...

Bacterial mutagenicity of pyrolysis tars produced from chloro-organic fuels.

Droplets of toluene and three chlorinated organics, ortho-dichlorobenzene, 1,2-dichloroethane, and trichloroethylene, were pyrolyzed in pure nitrogen. The composition and bacterial mutagenicity of the product tars were measured. The presence of organic chlorine was found to affect both pyrolysis product tar composition and total tar mutagenicity. Pyrolysis in the absence of chlorine produced ta...

Tumorigenicity of bay-region diol-epoxides and other benzo-ring derivatives of dibenzo(a,h)pyrene and dibenzo(a,i)pyrene on mouse skin and in newborn mice.

Dibenzo(a,n)pyrene, [DB(a,n)P], dibenzo(a,/)pyrene [DB(a,/)P], and seven of their benzo-ring derivatives were tested for tumorigenic activity on mouse skin and in newborn mice. In the tumor studies on mouse skin, a single topical application of 50, 200, or 600 nmol of compound was followed 7 days later by twice-weekly applications of the tumor promoter 12-O-tetradecanoylphorbol-13-acetate for 1...
