Many species of lichen-forming fungi contain yellow or orange extracellular pigments belonging to the dibenzofurans (usnic acid), anthraquinones (e.g. parietin) or pulvinic acid group. These pigments are all equally efficient light screens, leading us to question the potential ecological and

Galectin-1 (gal-1), which binds β-galactoside groups on various cell surface receptors, is crucial to cell adhesion and migration, and is found to be elevated in several cancers. Previously, we reported on 6DBF7, a dibenzofuran (DBF)-based peptidomimetic of the gal-1 antagonist

Levels of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/F) were determined in 23 blood samples of exposed workers from a transformer recycling plant in Dortmund, Germany. Compared to the most recent studies on German background levels of adults, elevated concentrations of up

An intramolecular, organocatalyzed Michael addition has been developed to obtain biologically important 2,3-disubstituted cis-2,3-dihydrobenzofurans. By using mandelic acid salts of primary aminocatalysts, derived from cinchona alkaloids, the intramolecular cyclization reaction has been developed to proceed in high yield, with moderate
Combustion runs at 700 °C in a horizontal laboratory furnace were carried out on two different electric wires (PVC and halogen-free wire). Tests were performed in the presence and in the absence of the metal conductor of the wires. The
