  • A NMR DNP equipment in Marseille!

    The Dynamic Nuclear Polarization technique allow to overcome the low sensitivity of the NMR technique thanks to the principle of the transfer of spin polarization from electrons to nuclei.

    Find this new equipment at the Spectropole of the Federation Sciences Chimiques Marseille

Atovaquone

Prevention of tumor growth and dissemination by in situ vaccination with mitochondria-targeted atovaquone

Advanced Science, 2022, e2101267

Atovaquone, an FDA-approved drug for malaria, is known to inhibit mitochondrial electron transport. In this study, researchers from the Medical College of Wisconsin, the Center for Cancer Prevention and the SREP team showed that the synthesized mitochondria-targeted atovaquone (Mito-ATO) increased mitochondrial uptake in both cancer cells and immunosuppressive cells in the TIME. Local intratumoral injection of Mito-ATO into primary tumors triggered potent T cell immune responses locally and in distant tumor sites.

Enantioselective Radical Reactions Using Chiral Catalysts

Chemical Reviews, 2022, on line

Enantioselective radical reactions have long been considered as rather limited for efficient stereocontrol, but recent developments have upturned this common belief. A spectacular advance in the development of catalyzed enantioselective radical reactions has been seen. Important innovations in the use of different chiral organocatalysts and transition-metal catalysts have been the major contributors in the development of enantioselective radical reactions.

Ultrafast Intersystem Crossing in Xanthone from Wavepacket Dynamics

J. Am. Chem. Soc. 2021, Accepted article

By means of quantum dynamic simulations, researchers of the CT team and the ICREA have established the photochemical mechanism of the atypical fast singlet-triplet transition in the excited state of Xanthone. They demonstrated the barrierless access to electronic state intersections. These intersections are close to minimum energy structures, allowing for such efficient non-radiative transition between singlets and triplets.

Monitoring Crystallization Processes in Confined Porous Materials by Dynamic Nuclear Polarization Solid-State Nuclear Magnetic Resonance

Journal of the American Chemical Society, 2021, 143, 6095−6103​

Researchers from the SACS and CMO teams showed that solid-state NMR, combined with dynamic nuclear polarization (DNP), enables efficient detection of metastable, transient species formed at the early stages of crystallization processes occurring in pure water under nanoconfinement. The approach relies on a new class of polarizing agents composed of mesoporous silica materials with TEMPO radicals embedded in the walls of the material, developed at the ICR.

Focus on the project of Juan Miguel Gonzalez Sanchez, PhD student at the LCE and the CROPS team

In the framework of the DOC2AMU program , Juan Miguel Gonzalez Sanchez of the Laboratoire de Chimie de l’Environnement (LCE) and the CROPS team is presenting his PhD work on “Multiphase reactivity of polyfunctional organic nitrates in the atmosphere : MULTI-NITRATES” in collaboration with the AtmoSud organisation.

Project supported by the European Commission, the Sud region (Provence-Alpes-Côte d’Azur), the CNRS and the A*Midex foundation of Aix Marseille University

Switching from single to simultaneous free radical and anionic polymerization with enamine-based organic electron donors

Angew. Chem. Int. Ed. 2021, Accepted article

The PCR and CROPS teams demonstrated that enamine-type organic electron donors are the first systems able to initiate either independent or simultaneous radical and anionic polymerizations.
