Thématiques du groupe

A – Chimie pour le Vivant

Nouveaux ligands du système nerveux central : dérivés de la cytisine

Depuis plusieurs années, le groupe étudie la chimie de la cytisine. Après avoir développé des approches méthodologiques pour son radiomarquage au carbone-11 (demi-vie : 20 min) et synthétisé des dérivés fluorés et marqués au fluor-18 (demi-vie: 110 min) pour des études in vivo des récepteurs nicotiniques, par tomographie par émission de positons (TEP), les recherches actuelles sont orientées vers la fonctionnalisation originale de la cytisine et la synthèse d’analogues pour leurs évaluations biologiques.

B – Chimie pour le développement durable

Parmi les différents « principes » de la chimie pour le développement durable, le groupe concentre ses efforts sur :

  • la recherche de réactions catalytiques organométalliques afin de réaliser de façon efficace des réactions en utilisant de faibles quantités de réactifs, limitant ainsi les déchets et les dépenses énergétiques ;
  • l’organocatalyse (décarboxylations-protonations énantiosélectives, réaction de Nazarov) permettant de s’affranchir des métaux, et de réaliser des réactions dans des conditions douces ;
  • l’utilisation de réactifs ou catalyseurs facilement préparés et peu coûteux incluant des dérivés des alcaloïdes du quinquina ;
  • la recyclabilité du catalyseur.

 

A – Chemistry for Life. New ligands of Central Nervous System receptors

For the last ten years, our group has studied the chemistry of cytisine mainly to provide radiotracers for in vivo studies of nicotinic receptors using positron emission tomography (PET). Thus, methodological approaches for cytisine radiolabelling with carbon-11 (half-life: 20 min) and synthesis of fluorinated derivatives including labelled with fluorine-18 (half-life: 110 min) have been developed. The current research is directed towards the functionalisation of the original cytisine and synthesis of analogues for biological assays.

  • Cytisine.
  • Synthesis of substituted cytisine derivatives and labelling with fluorine-18.
  • Rapid synthesis of amides and lactams. Applications in carbon-11 chemistry.
  • Carbon-6 functionalisation of cytisine.

B – Chemistry for sustainable development

Among the twelve « Green Chemistry Principles » the group focuses its efforts on :

  • the search for catalytic reactions mediated by transition metal in order to achieve efficient transformations using small amounts of reagents, reducing waste and energy costs;
  • the organocatalysis (enantioselective decarboxylative protonation, Nazarov reaction), a metal-free approach using mild conditions;
  • the use of reagents or catalysts easily prepared and inexpensive;
  • the recyclability of the catalyst.
