Biological context of fluoranthene

• The enzyme induction response to these compounds occurred in the following order: NFs greater than 3-NF greater than FL [16].
• Five metabolites produced by Cunninghamella elegans from fluoranthene (FA) in biotransformation studies were investigated for mutagenic activity towards Salmonella typhimurium TA100 and TA104 [17].
• Thus, our results demonstrate that the toxic effects of BaA and BbF on Sertoli cells are exerted through apoptosis, whereas FL and BaA do not elicit the apoptotic response [18].
• Utilization of fluoranthene by strain EPA 505 was demonstrated by increase in bacterial biomass, decrease in aqueous fluoranthene concentration, and transient formation of transformation products in liquid cultures where fluoranthene was supplied as the sole carbon source [19].
• Growth of mixed cultures with phenanthrene and fluoranthene solubilized by a nonionic surfactant prior to inoculation was exponential, indicating a high bioavailability of the solubilized hydrocarbons [20].

Anatomical context of fluoranthene

• Low levels of fluoranthene derivatives (1 times 10(-5) M) also strongly inhibited polymerase with polyinosinate-oligodeoxycytidylate [poly(I)-(dC)12-18], activated calf thymus DNA, and viral 70S RNA as templates, but not with polycytidylate-oligodeoxyguanylate as template [1].
• These inhibitory effects were not observed with microsomes prepared from FL-treated rats [16].
• These results demonstrate the applicability of the HPLC-32P-postlabelling procedure to detect and quantify fluoranthene-DNA adducts formed in vivo, and suggest that analysis of these adducts in accessible tissues such as lymphocytes may be a means of assessing chronic, high level exposure to fluoranthene [21].
• Chronic administration of fluoranthene in the diet, however, resulted in DNA adduct formation in most tissues examined, including liver, kidney, lung, small intestine, heart, spleen and lymphocytes; adducts were not detectable in testes DNA [21].
• Sertoli cells cultured in the presence of 10(-6) M and 10(-8) M FL showed morphologic changes [18].

Associations of fluoranthene with other chemical compounds

• These results suggest that fluoranthene switches from cAMP-dependent HCO(3)(-) secretion to Cl(-) secretion through the hIK-1 channel, whose sensitivity to protein kinase A may be up-regulated by the sustained [Ca(2+)](i) elevation produced by this chemical [22].
• In the present study, fluorescein diacetate uptake and the Comet assay were used to assess the cytotoxicity and genotoxicity of fluoranthene in HaCaT (human adult low calcium high temperature) cells in the presence or absence of ultraviolet A (UVA) irradiation [23].
• In in vitro studies, the PAH fluoranthene (FL) failed to increase or enhance CYP1A1-dependent ethoxyresorufin-O-deethylase (EROD) activity in cells, but rather inhibited activities induced by AhR agonists such as 2,3,7,8-tetrachlorodibenzo-p-dioxin and benzo(k)fluoranthene [24].
• Benz[a]anthracene (B[a]A), benzo[a]pyrene (B[a]P), fluoranthene, chrysene and 7,12-dimethylbenz[a]anthracene (DMBA) were acting as antiandrogens in vitro, resulting in IC(50) values of 3.2, 3.9, 4.6, 10.3 and 10.4 microM, respectively [25].
• Similarly, growth (biomass and shell size) was not affected by pyrene, fluoranthene, fluorene, carbazole, phenanthrene, or acridine, whereas dibenzothiophene gave a 10% effect concentration of 1600 mg/kg [26].

Gene context of fluoranthene

• Of these, only the fluoranthene derivatives were strong inhibitors of the viral DNA polymerase directed by polyadenylate-oligodeoxythymidylate [poly(A)-(dT)12-18] [1].
