    • Bio-inspired peptide-like ligands to help understanding metal toxicity, regulation and detoxification

      Séminaire du Dr Pascale Delangle (CEA Grenoble, France)
      Abstract :
      Peptides are promising metal-chelating agents, which offer many advantages over synthetic chemical compounds for biological and medical applications. They are made of the same building blocks as proteins and are therefore excellent mimics of biological sites that help predicting high affinity metal binding environments in vivo. They...

    • Dearomatizations of Nitroarenes by additions and cycloadditions

      Séminaire du Dr Isabelle Chataigner (Université de Rouen Normandie)
      Abstract :
      . Involving arenes in dearomatizing addition and/or cycloaddition reactions is an attractive and convergent approach to construct complex polycycles from easily accessible substrates, however, challenging because of their intrinsic stability.

      Abstract
      Our research focuses on the development of chemical reactions that are compatible with complex biological media. They are qualified as bioorthogonal when they can take place in a complex biological medium without distorting it, or as bio-specific when they touch only a precise part of it.
      Taking advantage of imaging...

    • Transition de spin photo-induite : développements récents

      Séminaire du Prof Guillaume Chastanet (ICMCB, Université de Bordeaux)
      Abstract
      Depuis le début des années 80, la commutation optique de complexes de Fe(II) à conversion de spin a suscité un engouement notable puisqu’elle laissait envisager des processus ultrarapides, à l’échelle de la molécule. Nous verrons que la photocommutation ne se restreint plus aux composés à conversion de spin et que la conception...
