Article Abstract
We report on the utilization of the ethylene-bridged bis[(dialkylamino)cyclopropenimine] (bisCPI) ligand, L, to give access to new main-group E(II) halide complexes (E = Ge, Sn, Pb; 1, 2, 3). Subsequent reduction with Collman's reagent (NaFe(CO) • dioxane) enables the isolation of a series of zero-valent tetrylone-tetracarbonyl iron complexes, (L)E(Fe(CO) (E = Ge (4), Sn (5), Pb (6)). Compounds 4 - 6 were reacted further with iron pentacarbonyl to yield the bis-tetracarbonyl iron complexes (L)E[(Fe(CO)] (E = Ge (7), Sn (8), Pb (9)). The electronic structure of these complexes was studied by Fe Mössbauer spectroscopy and computationally by density functional theory calculations.

Diabetic cardiomyopathy (DCM) is a severe cardiovascular complication of diabetes mellitus, characterized by pathological changes such as cardiomyocyte hypertrophy, necrosis, and myocardial fibrosis, which can ultimately lead to heart failure. However, its underlying mechanisms remain incompletely understood, limiting the development of effective therapeutic approaches. In recent years, the critical roles of oxidative stress and ferroptosis in the pathogenesis of DCM have attracted increasing attention.

The super bulky sodium phosphanide, NaP(SiPr), was reacted with amidinatotetrylenes LECl (L = PhC(NBu), E = Si, Ge), resulting in the formation of phosphasilene LSi(SiPr) = PSiPr () and phosphanido germylene LGeP(SiPr) (), respectively. Investigation on the reactivity of and toward elemental sulfur was carried out, where a stepwise reaction yielding the silanethione LSi(=S)SiPr () and the silicon thioester analogue LSi(=S)SSiPr () was observed in the case of , while the treatment of with sulfur exclusively afforded the germanium thioester analogue. In addition, the reactions of with Fe(CO) and GeCl·1,4-dioxane led to the germylene-coordinated iron carbonyl and the asymmetric Ge-Ge-bonded complex, respectively, exhibiting the reactivity of the lone pair as well as a weak Ge-P bond.

Precise control of spin states and spin-spin interactions in atomic-scale magnetic structures is crucial for spin-based quantum technologies. A promising architecture is molecular spin systems, which offer chemical tunability and scalability for larger structures. An essential component, in addition to the qubits themselves, is switchable qubit-qubit interactions that can be individually addressed.

Lycium barbarum is a traditional Chinese medicine that has been demonstrated to exhibit a wide variety of biological functions, such as antioxidation, neuroprotection, and immune modulation. The therapeutic effect of Lycium barbarum on intervertebral disc degeneration (IVDD) has not been conclusively established. In our study, we investigated the mechanisms of Lycium barbarum extract (LBE) using Network pharmacology and bioinformatic analyses.

Although temozolomide (TMZ) is routinely used in the treatment of glioblastoma multiforme, it is characterized by low stability, a short half-life, and serious side effects. Therefore, a new system for the effective, targeted delivery of TMZ based on superparamagnetic iron oxide nanoparticles (SPION) has been proposed. The nanoparticles were coated with hyaluronic acid, which acted as a stabilizing shell and targeting unit capable of effectively interacting with glioblastoma cells via the CD44 receptor.
