The aim of this study was to investigate the influence thermal treatment and ultrasound on activity β-glucosidase lipoxygenase, enzymes that determine phenolic composition sensory profile virgin olive oil. Enzyme determined spectrophotometrically in model systems consisting commercial their substrates. Thermal performed by tempering substrates at temperatures between 15 40 °C. measured 1 min af...

Studies on the mechanism of leukotriene B4 biosynthesis in suspensions composed of neutrophils plus erythrocytes indicate that human erythrocytes convert neutrophil-derived leukotriene A4 into leukotriene B4. Leukotriene B4 formation by neutrophils in the presence of erythrocytes exceeded that from corresponding suspensions of neutrophils alone. The increase was proportional to the erythrocyte ...

We report the discovery of a novel dual inhibitor targeting fungal sterol 14α-demethylase (CYP51 or Erg11) and human 5-lipoxygenase (5-LOX) with improved potency against 5-LOX due to its reduction of the iron center by its phenylenediamine core. A series of potent 5-LOX inhibitors containing a phenylenediamine core, were synthesized that exhibit nanomolar potency and >30-fold selectivity agains...
