Abstract Gross--Oliveira--Kohn (GOK) ensemble density-functional theory (GOK-DFT) is a time-\textit{independent} extension of density-functional theory (DFT) which allows to compute excited-state energies via the derivatives of the ensemble energy with respect to the ensemble weights. Contrary to…
Abstract Elucidating the lipidome of Archaea is essential to understand their tolerance to extreme environmental conditions. Previous characterizations of the lipid composition of Pyrococcus species, a model genus of hyperthermophilic archaea belonging to the Thermococcales order, led to…
Abstract We report a local, weight-dependent correlation density-functional approximation that incorporates information about both ground and excited states in the context of density functional theory for ensembles (eDFT). This density-functional approximation for ensembles is specially designed…
Summary Metalloenzymes use earth-abundant non-noble metals to perform high-fidelity transformations in the biological world. To ensure chemical efficiency, metalloenzymes have acquired evolutionary reactivity-enhancing tools. Among these, the entatic state model states that a strongly distorted…
Abstract Copper catalysis finds applications in various synthetic fields by utilizing the ability of copper to sustain mono- and bielectronic elementary steps. Further to the development of well-defined copper complexes with classical ligands such as phosphines and N-heterocyclic carbenes, a new…
Abstract Linalool is one of the most commonly used fragrance terpenes in consumer products. While pure linalool is considered as non-allergenic because it has a very low skin sensitization potential, its autoxidation on air leads to allylic hydroperoxides that have been shown to be major skin…
Abstract Tertiary enamides display versatile reactivity and great stability compared to their enamine congeners. This review covers progress made in the development of new methods involving the enaminic reactivity of tertiary enamides with respect to the synthesis of complex nitrogen-containing…
Summary Nitro compounds are known to change reaction rates and kinetic concentration dependence of Brønsted‐acid‐catalyzed reactions. Yet, no mechanistic model exists to account for these observations. Herein we present an atomistic model for the catalytically active form for an alcohol…
Summary Glycine receptors (GlyR) mediate fast inhibitory neurotransmission in the brain and have been recognized as key pharmacological targets for pain. We have collected 218 unique chemical entities with documented modulatory activities at the GlyR and built a database named GRALL. This…
Abstract Previously reported ferromagnetic triangles (NnBu4)2[Cu3(μ‐Cl)2(μ‐4‐NO2‐pz)3Cl3] (1), (PPN)2[Cu3(μ‐Cl)2(μ‐pz)3Cl3](2), (bmim)2[Cu3(μ‐Cl)2(μ‐pz)3Cl3] (3) and newly reported (PPh4)2[Cu3(μ‐Cl)2(μ‐4‐Ph‐pz)3Cl3] (4) were studied by magnetometry, Electron Paramagnetic Resonance (EPR)…
Abstract Anaerobic ammonium oxidation (anammox) is a major process of bioavailable nitrogen removal frommarine systems. Previously, a bacteriohopanetetrol (BHT) isomer, with unknown stereochemistry, elut-ing later than BHT when examined by high performance liquid chromatography (HPLC), was…
Abstract The copper(I)‐exchanged zeolite CuI‐USY proved to efficiently catalyze the direct azidation of arylboronic acids with sodium azide under simple and practical conditions, namely at room temperature under air with methanol as solvent and without any additive. This easy‐to‐prepare and cheap…
Abstract Bacteria and Eukarya organize their plasma membrane spatially into domains of distinct functions. Due to the uniqueness of their lipids, membrane functionalization in Archaea remains a debated area. A novel membrane ultrastructure predicts that monolayer and bilayer domains would be…
Abstract The measurement of exchangeable Cu2+ levels in biological samples is gaining interest in the context of copper-related pathologies. Here, we report a Tb3+ luminescent turn-off sensor for Cu2+ based on the specific and suitable-affinity Xxx-Zzz-His (ATCUN) peptide motif, enabling Cu2+…
Abstract The pentamethylcyclopentadienyl N‐heterocyclic carbene nickel complex [Ni(η 5 ‐C 5 Me 5 )Cl(IMes)] (IMes = 1,3‐dimesitylimidazol‐2‐ylidene) efficiently catalyses the anti‐Markovnikov hydroboration of alkenes with catecholborane in the presence of a catalytic amount of potassium tert…
Abstract Two (so‐called left and right) variants of N‐centered ensemble density‐functional theory (DFT) are presented. Unlike the original formulation of the theory, these variants allow for the description of systems with a fractional electron number. While conventional DFT for open systems uses…
Abstract Copper-complexes are of medicinal and biological interest, including as anticancer drugs designed to cleave intracellular biomolecules via O2 activation. To exhibit such activity, the copper complex must be redox-active and resistant to dissociation. Metallothioneins (MTs) and glutathione…
Abstract IspH/LytB, an oxygen‐sensitive [4Fe‐4S] enzyme, catalyzes the last step of the methylerythritol phosphate (MEP) pathway, a target for the development of new antimicrobial agents. This metalloenzyme converts (E)‐4‐hydroxy‐3‐methylbut‐2‐en‐1‐yl diphosphate (HMBPP) into the two isoprenoid…
Abstract A series of three new polyoxometalate/spiromolecule compounds – including the (TBA)3[AlMo6-SN] (SN = spironaphthoxazine) and (TBA)3[AlMo6-SP] (SP = spiropyran) Anderson-type polyoxometalates (POMs) and the unprecedented (TBA)5[P2W15V3-SP] Dawson-type species – has been synthesized and…
Abstract Mounting evidence supports the role of amyloidogenesis, oxidative stress, and metal dyshomeostasis in the development of neurodegenerative disorders. Parkinson's Disease is characterized by α-Synuclein (αSyn) accumulation and aggregation in brain regions, also promoted by Cu2+. αSyn is…
