Pyrrolizidine alkaloids (PAs) and their corresponding N-oxides (PANOs) are natural protoxins biosynthesised by many plant species and are responsible for occasional fatal intoxication outbreaks due to the consumption of contaminated food. However, on

Analytical strategies for the determination of pyrrolizidine alkaloids in plant based food and examination of the transfer rate during the infusion process

Autor: Jean-François Picron, Mélanie Herman, Els Van Hoeck, Séverine Goscinny

Publikováno v: Food Chemistry. 266:514-523

Two sample preparation methods were developed (graphitised carbon and C18 solid phase extraction clean-up) and validated in house using liquid chromatography and tandem mass spectrometry (MS/MS) for the determination of 30 pyrrolizidine alkaloids (PA

Monitoring of pyrrolizidine alkaloids in beehive products and derivatives on the Belgian market

Autor: Els Van Hoeck, Jean-François Picron, Mélanie Herman, Séverine Goscinny

Publikováno v: Environmental science and pollution research international. 27(6)

Pyrrolizidine alkaloids (PAs) and related N-oxides (PANOs) are secondary plant metabolites thought to be found in approximately 3% of the flowering plants worldwide and exhibiting hepatotoxic properties to humans. As a consequence, beehive products a

Ipso-Nitration of Calix[6]azacryptands: Intriguing Effect of the Small Rim Capping Pattern on the Large Rim Substitution Selectivity

Autor: Manuel Lejeune, Alice Mattiuzzi, Benoit Colasson, Ivan Jabin, Olivia Reinaud, Andrea Brugnara, Stéphane De Cesco, David Coquière, Grégory Thiabaud, Angélique Lascaux, Jean-François Picron, Ulrich Darbost

Publikováno v: The Journal of Organic Chemistry. 77:3838-3845

The ipso-nitration of calix[6]arene-based molecular receptors is a important synthetic pathway for the elaboration of more sophisticated systems. This reaction has been studied for a variety of capped calixarenes, and a general trend for the regiosel

Fluorescent chemosensors for anions and contact ion pairs with a cavity-based selectivity

Autor: Ivan Jabin, Jean-François Picron, Karolina Flidrova, Emilio Brunetti, Gilles Bruylants, Kristin Bartik

Publikováno v: The Journal of organic chemistry. 79(13)

The association of a concave macrocyclic compound to one or multiple fluorophores is an appealing strategy for the design of chemosensors. Indeed, as with biological systems, a cavity-based selectivity can be expected with such fluorescent receptors.
