Sphaeropsidin A C15-C16 Cross-Metathesis Analogues with Potent Anticancer Activity.
Drug Drug Screening Assays, Antitumor Humans Molecular Structure Pyrenes Structure-Activity Relationship Abstract: We recently discovered that sphaeropsidin A (SphA), a fungal metabolite from Diplodia ...
Polycyclic aromatic hydrocarbons in spices and dried herbs and associated risk for the Belgian population
occurrence of the four EU regulated polycyclic aromatic hydrocarbons (ΣPAH4). Samples were sorted in three groups according to their use: traditional spices, exotic spices, and herbs. Benzo[a]pyrene has been ...
Assessing the receptor-mediated activity of PAHs using AhR-, ERα- and PPARγ- CALUX bioassays
fluoranthene, pyrene and fluorene showed weak agonistic activity, whilst benzo(a)pyrene (B(a)P) was the only one exhibiting weak antagonistic activity. For the AhR- CALUX, chrysene was the only PAH that showed ...
Assessing the endocrine activity of PAHs using the DRE-, ERE- and PPARγ CALUX bioassays
pyrene and fluorene showed a weak agonistic activity for the PPAR y receptor. Only BaP showed a weak antagonistic activity. In both the agonistic and antagonistic tests, no effects were observed in ...
Modular Method for the Determination of Polycyclic Aromatic Hydrocarbons in Spices and Dried Herbs by Gas Chromatography–Tandem Mass Spectrometry
s),(benzo[a]anthracene [BaA], chrysene [CHR], benzo[b]fluoranthene [BbF] and benzo[a]pyrene [BaP]), in the wide matrix groupof spices and dried herbs by gas chromatography–tandem mass spectrometry (GC – MS / MS). The ...
Clean up strategy for the analysis of PAH in food of animal origin
population to benzo[a]pyrene (B[a]P). To protect human health, many competent Authorities has established maximum residue levels in food. In Europe, a MRL is fixed for B[a]P, considered as a marker for PAH ...
Characterization of cultures enriched from acidic polycyclic aromatic hydrocarbon-contaminated soil for growth on pyrene at low pH.

Distribution of the Mycobacterium community and polycyclic aromatic hydrocarbons (PAHs) among different size fractions of a long-term PAH-contaminated soil.
majority of the PAH s and showed immediate pyrene- and phenanthrene-mineralizing activity upon addition of (14)C-labelled pyrene or phenanthrene. In contrast, the sand and silt fractions showed a lag time of ...
Use of the pAL5000 replicon in PAH-degrading mycobacteria: application for strain labelling and promoter probing.
pyrene, respectively, were successfully electroporated with pAL5000-based plasmids containing the green fluorescent protein (gfp) gene of Aequoria victoria under the control of the hsp60 promoter of ...
Differential responses of eubacterial, Mycobacterium, and Sphingomonas communities in polycyclic aromatic hydrocarbon (PAH)-contaminated soil to artificially induced changes in PAH profile.
