Primary cultures of hamster epidermal cells exposed to hy drocarbon, 1 fig/ml, rapidly metabolized [3H]benzo(a)pyrene and [14C]7,12-dimethylbenz(a)anthracene to ethyl acetate:acetoneand water-soluble metabolites. By 24 hr, only 13.6% of the organic solvent-soluble radioactivity recovered in the medium was unchanged [3H]benzo(a)pyrene, and only 5.9% was unchanged [14C]7,12-dimethylbenz(a)anthrac...

The title compounds, C23H16S, (I), and C26H16S, (II), are benzo-thio-phene derivatives in which the benzo-thio-phene moiety is fused with a naphthalene ring system in (I), and with an anthracene ring system in (II). In (I), the mean plane of the benzo-thio-phene ring system makes a dihedral angle of 2.28 (6)° with the naphthalene ring system, and a dihedral angle of 1.28 (6)° with the anthracen...

In this study, the enzyme activity of anthraquinone compounds which were synthesized beforehand by our research group was investigated. Molecular docking studies performed for 1-(4-aminophenylthio)anthracene-9,10-dione (3) and 1-(4-chlorophenylthio)anthracene-9,10-dione (5). Compound 3 from reaction 1-chloroanthraquinone (1) 4-aminothiophenol (2). 5 4-chlorothiophenol (4). Anthraquinone analogs...

The catalytic activity of the binary composite catalysts Fe2O3-CoO/CaA and Fe2O3-CoO/ZSM-5 was studied. They were obtained by impregnation CaA ZSM-5 zeolites with aqueous solutions sulfates iron (FeSO4·7H2O) cobalt (CoSO4·7H2O). total metal content no more than 5%. Then, oxidizing burning at 720 °C for 60 min performed to produce oxides. It found that Fe-Co/CaA catalyst contains as CoFe2O4 comp...

Currently experts are actively working on Russian specifications for herbal drugs, drug preparations, and medicinal products, specifically analytical procedures to evaluate the quality of these medicines. The aim this study was provide a scientific basis improving qualitative quantitative analysis preparations products containing phenolic compounds. It shown that chemical nature, physicochemica...
