Abstract The first soluble and stable Mg2+ dication stabilized only by weakly coordinating and chemically robust carborate anions [HexCB11Cl11]− is described. Mg[HexCB11Cl11]2 (1), prepared by reaction of Mg(nBu)2 with 2 equiv of [Ph3C][HexCB11Cl11], consists, in the solid state, of a central Mg2+…
Abstract Ru complexes are widely studied in photodynamic therapy. The type I mechanism of action is based on a photoinduced electron transfer from the complex to O2 and needs an electron donor to be catalytic. Little is known about electron donors among physiologically relevant compounds. Hence, we…
Abstract Hypersaline environments, including brines and brine inclusions of evaporite crystals, are currently of great interest due to their unique preservation properties for the search for terrestrial and potentially extraterrestrial biosignatures of ancient life. However, much is still unclear…
Abstract Archaeal membranes exhibit remarkable stability under extreme environmental conditions, a feature attributed to their unique lipid composition. While it is widely accepted that tetraether lipids confer structural integrity by forming monolayers, the role of bilayer-forming diether lipids…
Abstract Cu(II) coordination complexes are emerging as promising anticancer agents due to their ability to induce oxidative stress through reactive oxygen species (ROS) generation. In this study, we synthesized and characterized two novel Cu(II) metallopeptide systems, 1/Cu(II) and 2/Cu(II),…
Abstract Oxidatively induced reductive elimination (OIRE) has become a crucial chemical process to enable the effective formation of otherwise much less accessible products. The chemically, electrochemically, or photochemically triggered oxidation of appropriate metal complexes leading to a…
Abstract Electric fields represent an ideal means for controlling spins at the nanoscale and, more specifically, for manipulating protected degrees of freedom in multispin systems. Here we perform low-temperature magnetic far-IR spectroscopy on a molecular spin triangle (Fe3) and provide initial…
Absract Iron-copper complexes have been extensively studied in the search for efficient cytochrome c oxidase models. Whereas most dinuclear materials usually focus on fine-tuning the coordination of heme-Fe, this work shows that the coordination of copper in cytochrome c oxidase models should be…
Abstract The present study details the synthesis and characterization of a robust, monomeric Al–H aluminate supported by a tridentate tris-phenolate ligand, isolated as [2][Li(THF)4] and [2][N(nBu)4] salts, which were then exploited as CO2 hydroboration catalysts. As initial reactivity studies, it…
Abstract In this study, water-soluble colloidal platinum nanoparticles (Pt NPs) have been stabilized with novel thiolated cyclodextrins (CD-SH) and their catalytic performance has been investigated. We varied the size of the CD cycle (α-CD/β-CD), the degree of thiolation (one or two thiol groups…
Abstract A Kohn–Sham (KS) density-functional energy expression is derived for any (ground or excited) state within a given many-electron ensemble along with the stationarity condition it fulfills with respect to the ensemble density, thus giving access to both physical energy levels and…
Abstract The discovery of a stable organic radical formed under mild, clean, and efficient light-mediated conditions is reported. The structure of the stable acridinium-based radical photoproduct was unambiguously established by single-crystal X-ray diffraction, mass spectrometry, and in solution…
Abstract In this review, the difference between π-mers (pimers) and π-dimers (pi-dimers) will be discussed. Often interchanged or confused in the literature, these two radical interactions lead to different or even opposite physico-chemical behaviors. This review aims at clarifying the terms π-mers…
Abstract Imaging extracellular Cu2+ in vivo is of paramount interest due to its biological importance in both physiological and pathological states. Magnetic resonance imaging (MRI) is a powerful technique to do so. However, the development of efficient MRI contrast agents selective for Cu2+,…
Abstract The lipid cis-trans isomerase (Cti) is a periplasmic heme-c enzyme found in several bacteria including Pseudomonas aeruginosa, a pathogen known for causing nosocomial infections. This metalloenzyme catalyzes the cis-trans isomerization of unsaturated fatty acids in order to rapidly…
Abstract The use of VIV and CuII spins to design weakly coupled and dissymmetric spin systems has been examined. Such systems were synthesized using porphyrin-based complexes, with external coordination sites allowing for the formation of dimers via a PdII linker ion. Continuous-wave (CW) Electron…
ABSTRACT A totally controlled regiodivergent azidation of activated N-allenamides is presented. Using TMSN3/TBAF, β-azidation of N-allenamides occurs exclusively, yielding vinyl azides. Conversely, employing a TFA/TMSN3 mixture results solely in the formation of γ-azides. A subsequent formal…
Tweet The IFM team in collaboration with researchers at ENS Lyon and Institut Pasteur used advanced molecular simulations to investigate how cannabinoids bind to glycine receptors, an important pharmacological target for chronic pain. They discovered that tetrahydrocannabinol (THC) and anandamide…
Abstract Several copper-ligands, including 1,10-phenanthroline (Phen), have been investigated for anticancer purposes based on their capacity to bind excess copper (Cu) in cancer tissues and form redox active complexes able to catalyse the formation of reactive oxygen species (ROS), ultimately…
