A NMR DNP equipment in Marseille!
More infoThe 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

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.
