Inorganic Chemistry (VIEWPOINT)

Abstract Over the past three decades, Single-Molecule Magnets (SMMs) have demonstrated consistently higher barriers for magnetization reversal (Ueff) and blocking temperatures (TB), exhibiting extremely slow magnetic relaxation at low temperatures. This and other associated phenomena, provided…

Journal of the American Chemical Society

Abstract Conformational dynamics play key roles in molecular reactivity and the development of functional molecular machines. In this study, we investigate the competitive correlation between internal rotations about the C–NR2 bonds and cross-conjugation dynamics in DAMN, DAFN, and their…

Journal of Inorganic Biochemistry

Graphical Abstract Ruthenium(II) p-cymene complexes with acylthiourea ligands (1–3) were synthesized and structurally characterized, showing neutral monodentate κ1-S coordination. Computational analyses revealed that ligand–metal bonding is dominated by the sulfur–ruthenium interaction. The…

Physical Chemistry Chemical Physics

Graphical Abstract The Independent Gradient Model, applied to the dynamics of carbene ligand insertion into a C–Mn bond, reveals details of electron density redistribution events, challenging earlier assumptions. The unique stereoselectivity of the reaction is rationalised by the joint use of the…

Dalton Transactions

Abstract In the pursuit of CuII-responsive MRI contrast agents with enhanced CuII affinity, we report the synthesis and characterization of two LnIII-DO3A-C3AmpicGH complexes (LnIII = GdIII, EuIII), featuring a tetradentate CuII-binding moiety, along with the corresponding mononuclear CuII-C3AmpicG…

Inorganic Chemistry

Abstract α-N-Pyridylthiosemicarbazones (PTSC) are anticancer agents that can induce oxidative stress in cells, likely through interactions with metal ions. Redox-active Cu and Fe bind strongly to PTSC, forming complexes Cu-PTSC and Fe-PTSC2. These complexes have been proposed to directly catalyze…

Comptes Rendus. Chimie

Abstract Over the last few decades, allenes have evolved from objects of curiosity to central elements of organic synthesis. Among them, N-allenamides, allenes featuring an electron-withdrawing group on the nitrogen, stand out for their great stability and versatility. Their unique reactivity has…

Chemistry-A European Journal

Abstract IspG (also known as GcpE) is a key [4Fe-4S] metalloenzyme that catalyzes the penultimate step of the methylerythritol phosphate (MEP) pathway, a well-established target for the development of new antimicrobials. This oxygen-sensitive enzyme mediates the reductive dehydroxylation of 2-C-met…

Journal of Chemical Theory and Computation

Abstract Localized orbital-based quantum embedding, as originally formulated in the context of density matrix embedding theory (DMET), is revisited from the perspective of lattice density functional theory (DFT). An in-principle exact (in the sense of full configuration interaction) formulation of…

Neurochemistry International

Abstract The intricate interplay between brain iron homeostasis and pathological α-Synuclein (αSyn) in Parkinson's Disease (PD) is still unclear. αSyn is the primary protein involved in disease progression and promotes cytotoxicity by impairing dopamine synthesis, mitochondrial dysfunction and…

Inorganic Chemistry

Abstract The failure of the therapeutic administration of superoxide dismutase (SOD) and catalase (CAT) enzymes to prevent oxidative stress has fostered the development of metal complexes that are capable of mimicking their activity. In the present work, two new pyridine azacyclophane ligands…

Biochemistry

Abstract In this study, we present an atomic-level structural investigation of the magainin 2 antimicrobial peptide reconstituted in extended lipid bilayers that closely mimic the composition of bacterial membranes. Using state-of-the-art solid-state NMR spectroscopy, we show that within…

Chemistry - A European Journal

Abstract The 1:1 complex of a bis(acridinium-Zn(II)porphyrin) host and a tetrapyridyl free-base porphyrin guest shows a remarkable interplay of energy and electron transfer (eT) processes, finely tuned by the solvent polarity or the selection of the photoexcited component. A more polar environment…

The Journal of Physical Chemistry A

Abstract Following a recent work [E. Fromager, J. Phys. Chem. A 2025, 129 (4), 1143−1155] on the ensemble density functional theory (DFT) of excited electronic energy levels, we derive, in this paper, the ensuing static linear response theory, thus allowing for an in-principle exact evaluation of…

Biomacromolecules

Abstract Vectofusin (VF) is a histidine-rich amphipathic peptide designed to enhance lentiviral transduction for gene therapeutic applications, where its assembly into fibrils requires polyvalent anions. In this study, we used solid-state NMR, transmission electron microscopy, and titration…

Journal of the American Chemical Society

Abstract Cathelicidin-BF (CatBF) is a LL-37 homologous antimicrobial peptide (AMP) isolated from Bungarus fasciatus with an exceptional portfolio of antimicrobial, antiviral, antifungal, and anticancer activities. Contrary to many AMPs, it showed a good pharmacological profile with a half-life of…

Biophysical Chemistry

Abstract Here we present studies of the structure and membrane interactions of ecPis-4 s, a new antimicrobial peptide from the piscidin family, which shows a wide-range of potential biotechnological applications. In order to understand the mode of action ecPis-4 s, the peptide was chemically…

Antibiotics

Abstract Background/Objectives: This study investigates the structural and biophysical properties of the wild-type antimicrobial peptide LyeTx I, isolated from the venom of the spider Lycosa erythrognatha, and its analog LyeTx I-b, designed to enhance antibacterial activity, selectivity, and…

Abstract Cyclodextrins (CDs) are bio-based and biodegradable oligosaccharides, enzymatically derived from starch, offering low toxicity and renewability, thus representing an interesting renewable feedstock. While chemical modification allows for precise tailoring of their properties, greater…

An-Najah University Journal for Research

Abstract This study shows that the nanoparticles produced by the reductive decomposition of a cobalt (+III) metallacycle derived from 2-phenylpyridine upon treatment with the highly nucleophilic Na[Et3BH] are capable of promoting the Kumada- Corriu cross coupling of aryl halides with…
