J. Comp. Chem. [LCQ]

Résumé: Une description en principe exacte des excitations électroniques “double” (promotion de deux électrons des orbitales occupées dans l’état fondamental vers des orbitales de plus hautes énergies) en théorie de la fonctionnelle de la densité (DFT) est proposée. Ces dernières sont absentes des spectres de DFT dépendante du temps (TDDFT) standard du fait de l’approximation adiabatique...[En savoir plus]

Front. Mol. Biosci. [BCB]

Abstract: CPPs, or Cell-Penetrating Peptides, offer invaluable utility in disease treatment due to their ability to transport various therapeutic molecules across cellular membranes. Their unique characteristics, such as biocompatibility and low immunogenicity, make them ideal candidates for delivering drugs, genes, or imaging agents directly into cells. This targeted delivery enhances treatment...[En savoir plus]

Metallomics [BCB/POMAM/Biophysique des membranes et RMN]

Abstract: Metal ion-catalysed overproduction of reactive oxygen species (ROS) are believed to contribute significantly to oxidative stress and be involved in several biological processes, from immune defence to development of diseases. Among the essential metal ions, copper is one of the most efficient catalysts in ROS production in the presence of O2 and a physiological reducing agent such as...[En savoir plus]

Chemistry – A European Journal [POMAM]

Graphical Abstract The diradical formed by functionalizing the yttrium(III)-phthalocyaninato radical with a nitroxide radical, is characterized by an engineered g-tensor asymmetry and a weak exchange coupling. Interestingly, its behavior is reminiscent of a spin qutrit, exhibiting two EPR transitions characterized by different Rabi frequencies and whose amplitudes can be selectively enhanced by...[En savoir plus]

Organometallics [LCSOM/ Biophysique des membranes et RMN]

Abstract: This study addresses the chemoselectivity of the catalyzed reduction of a series of variously substituted γ-lactams by Et3SiH mediated by a pentamethylcyclopentadienyl iridacyclic acetonitrilo salt derived from benzo[h]quinoline. Introduction of an unsaturation within the 5-membered ring of the γ-lactam annihilates the precedence of the amide function over the capture of the silylium...[En savoir plus]

Angewandte Chemie [OMECA/LCQ/POMAM]

Abstract: Flavins and their alloxazine isomers are key chemical scaffolds for bioinspired electron transfer strategies. Their properties can be fine-tuned by functional groups, which must be introduced at an early stage of the synthesis as their aromatic ring is inert towards post-functionalization. We show that the introduction of a remote metal-binding redox site on alloxazine and flavin...[En savoir plus]
