Characterization of benzopyrene metabolism in rat pancreas

Cancer Letters, 1983
The present studies characterized the pancreatic metabolic system which biodegrades benzo[a]pyrene (BP), in male Sprague-Dawley rats pretreated with 20 mg/kg 3-methylcholanthrene (3MC), 75 mg/kg phenobarbital (PB) or solvent as control. Type of cytochrome involved was examined by measuring the reaction in the presence of 7,8-benzoflavone (BF), an ...

Putrescine as inhibitor of 3,4-benzopyrene cancerogenesis

European Journal of Cancer (1965), 1975
Abstract The cancerogenic action of 3,4 -benzopyrene ( 3,4 -BP) can be reduced by substances physiologically occurring in organism of several animal species and human beings, as well as by a number of synthetically-prepared compounds. Experimental investigations on female mice (IMRI-strains, 4–5 weeks old, 20–25 g of body weight) have revealed ...

Synthesis of Chrysoporphyrins and a Related Benzopyrene-Fused System

The Journal of Organic Chemistry, 2022
Reaction of 6-nitrochrysene with ethyl isocyanoacetate in the presence of a non-nucleophilic base gave a c-annulated pyrrole ethyl ester that was used to prepare chrysene-fused tripyrranes and a chrysopyrrole dialdehyde. Chrysene-fused tripyrranes were reacted with a pyrrole dialdehyde, but poor yields of chrysoporphyrins were obtained.

Trimer exciplex emission in benzopyrene

The Journal of Chemical Physics, 1980
The authors study the emission spectra taken for 3,4,9,10-dibenzopyrene in benzene, when the main pulsed N2 laser beam (3371 Å) was used as a source of excitation.(AIP)

Investigations on the extinction of the fluorescence of 3,4-benzopyrene

Acta Physica Academiae Scientiarum Hungaricae, 1962
As a result of the effect of ozone, or ultraviolet irradiation the fluorescence of 3,4-benzopyrene decreases with increasing time of treatment, i. e. with increased amount of ozone introduced into the samples. At the same time the ultraviolet absorption peaks decrease too.
