The synthesis of some 9,10-disubstituted anthracene derivatives are described. 9,10-Bis(2-bromoethyl) anthracene 4,9,10-Bis (2-cyanoethyl) anthracene 5 and 9,10-Bis (4-hydroxybutyl) anthracene 11 are synthesized for the first time.

Anthracene is a widespread environmental pollutant with carcinogenic and genotoxic properties. Biodegradation is a simple, cost-effective and safe technique to clean-up contaminated environments. The aims of this study are isolation and characterization of an oligotrophic bacterium with the ability to degrade anthracene and the assessment of in vitro biodegradation process. For this purpose pet...

By means of ab-initio calculations on the basis of the FPLAPW method, we compared the energy loss near edge structure (ELNES) of carbon K edges in crystalline phenanthrene and its isomer, anthracene. In these two organic compounds, different non-equivalent carbon atoms can result in distinct K edge spectra due to the different carbon-carbon bond lengths, as a characteristic behavior of the mole...

Benz[a]anthracene and the five metabolically possible trans-dihydrodiols of benz[a]anthracene were tested for carcinogenicity in newborn Swiss-Webster mice. Four hundred, 800, and 1600 nmoles hydrocarbon i.p. were sequentially injected on Days 1, 8, and 15 of life. The mice were killed at 22 weeks of age. Of the mice treated with trans-3,4-dihydroxy-3, 4-dihydrobenz[a]anthracene, 24% developed ...

phytoremediation is a sustainable and environment friendly remediation technique, the potential of which in removal of soil contaminants has been well documented. on the other hand the activity of earthworms helps improve soil conditions. hence, it is expected that in soil presence of earthworms can enhance the rate of phytoremediation as regards anthracene. the aim followed in this work was to...

Temperature dependences of the free energy (F), entropy (S) and heat capacity (C_v) are calculated (P=0) for organic compounds (solid benzene, naphthalene anthracene) by using quasiharmonic approximation. Contributions to those thermodynamic functions due Raman frequencies lattice modes benzene), librational (naphthalene), phonons vibrons (anthracene) taken into account in our calculations. We ...

K-region epoxides of benz[a] anthracene, dibenz[a,h] anthracene, and 3-methylcholanthrene have been found to be toxic and more active in producing malignant transformation of cells derived from mouse prostate than their respective parent hydrocarbons and K-region dihydrodiols and phenols. The data support the view that metabolism of these polycyclic hydrocarbons is a prerequisite for their biol...

Armillaria sp. F022, a white-rot fungus isolated from decayed wood in tropical rain forest was used to biodegrade anthracene in cultured medium. The percentage of anthracene removal by Armillaria sp. F022 reached 13 % after 7 days and at the end of the experiment, anthracene removal level was at 87 %. The anthracene removal through sorption and transformation was investigated. 69 % of eliminate...
