Ionization energies of benzo[a]pyrene and benzo[e]pyrene

The Journal of Chemical Physics, 1997
Photoelectron spectra of benzo[a]pyrene and benzo[e]pyrene have been assigned on the basis of ab initio electron propagator theory. Electron correlation effects are included in the partial third order approximation and agreement with experimental peaks is very close.

Metabolism of benzo[a]pyrene VI. Stereoselective metabolism of benzo[a]pyrene and benzo[a]pyrene 7,8-dihydrodiol to diol epoxides

Chemico-Biological Interactions, 1977
Abstract (±)-7β,8α-Dihydroxy-9β,10β-epoxy-7,8,9,10-tetrahydrobenzo[a]pyrene (diol epoxide-1) and (±)-7β,8α-dihydroxy-9α,10α-epoxy-7,8,9,10-tetrahydrobenzo[a]pyrene (diol epoxide-2) are highly mutagenic diol epoxide diastereomers that are formed during metabolism of the carcinogen (±)-trans-7,8-dihydroxy-7,8-dihydrobenzo[a]pyrene.

Excretion of benzo[a]pyrene-Gua adduct in the urine of benzo[a]pyrene-treated rats

Chemico-Biological Interactions, 1986
A benzo[a]pyrene(BP)-Gua adduct was extracted in the urine of rats treated with BP. Some (0.15%) of the administered dose of BP was excreted as BP-Gua within 48 h. A double labelling experiment demonstrated that the excreted product contained both a BP and a Gua moiety.

Benzo[a]pyrene-collagen interactions

Chemico-Biological Interactions, 1983
In vitro interactions of benzo[a]pyrene (BaP) with acid-soluble type I collagen from rat tail tendon have been investigated. The fluorescence of BaP increases in the presence of collagen. Bound BaP inhibits the formation of collagen fibrils in solution.

Benzo[a]pyrene antibody inhibition of benzo[a]pyrene-induced mutagenesis

Cancer Letters, 1979
Summary An antibody to benzo[ a ]pyrene (BP) was prepared. The isolated antibody showed a specificity for BP and a low reactivity with another carcinogenic hydrocarbon, 7,12-dimethylbenz[ a ] anthracene (DMBA). The BP-antibody inhibited the in vitro cytotoxic and mutagenic activity of BP in both a rat embryo fibroblast- and a rat lung cell-mediated ...

Risk assessment for benzo[a]pyrene

Regulatory Toxicology and Pharmacology, 1991
Benzo[a]pyrene is the most studied carcinogenic polycyclic aromatic hydrocarbon and one of the most potent, and it is often used as a toxicological prototype or surrogate for all carcinogenic polycyclic aromatic hydrocarbons. Quantitative risk assessment of benzo[a]pyrene has been hampered by the quality of the data sets available for quantitation. The

Metabolism of Benzo(a)Pyrene and Benzo(a)Pyrene 4,5-Oxide in Rabbit Lung

1982
For several years our laboratory has been investigating the biotransformation of various environmental pollutants by lung. Studies have been performed with pulmonary subcellular fractions, purified monooxygenase and glutathione transferase enzymes, and preparations having intact cellular structure including the isolated perfused lung and cell fractions
