Summary: A stable square-planar Cu(iii) complex, [bis(toluene-3,4-dithiolato)copper(iii)][NEt3H], has been synthesised and characterised using various analytical techniques. Interestingly, a unique [(toluene-3,4-dithiolato)Cu(iii)(peroxide)](-) complex is formed when the complex is fragmented in FTICR-MS upon reaction with oxygen. Additionally, natural 1,2-dithiolenes known to bind molybdenum may play a role in stabilising Cu(iii) in vivo.

Summary: This study investigates the ion exchange behavior of the CeL3 coordination polymer (CP) and elucidates its mechanism. It is found that the limit of Ln(3+)-to-Ce3+ mixing (x(lim)) in the crystal is an important factor for the feasibility of structural transition. When the mixing ratio (x) of Ln(3+) is above x(lim), the crystal structure tends to transition and the exchange of Ce3+ for Ln(3+) is facilitated.

Summary: This review focuses on the interaction between fermentable substrates and selected minerals in nutrient digestion and absorption to determine nutritional solutions for maximizing animal performance. However, there is currently no standardized method to assess in vitro mineral digestion. The total tract digestibility of phosphorus might be underestimated in diets with fermentable ingredients, and further research is needed to calculate the true total tract digestibility of phosphorus. The quantification of fiber type, composition, and its influence on digestion kinetics and nutrient solubility should be considered in diet formulation.

Summary: The metabolic preference of cells toward glycolysis often indicates a diseased state ranging from cancer to other dysfunctions. When a particular cell type utilizes glycolysis as a major energy production pathway, their mitochondria become impaired resulting in a cascade of events which eventually contributes to resistance towards therapies to tackle such diseases. In abnormal tissues such as seen in the tumor microenvironment, when cancer cells utilize glycolysis, other cell types such as the immune cells switch their metabolism and prefer such glycolysis.

Summary: Tumor cells develop resistance to multimodal cancer therapy, including cisplatin, by relying on fatty acid oxidation (FAO). In this study, we validated the expression of an important enzyme, CPT1A, in patient biopsies and discovered that the cisplatin prodrug, Platin-L, can inhibit FAO by interacting with CPT1A. We further synthesized cisplatin-based prodrugs and found that the presence of a carboxylic acid group near the fatty acid linker is crucial for CPT1A binding. By disrupting fat metabolism with Platin-L, prostate cancer cells transition to a glucose-dependent chemosensitive state. We incorporated Platin-L into a nanocarrier for targeted delivery to the tumor microenvironment and demonstrated its efficacy and safety.

Summary: This work presents studies on the photochemical transformations of TU and Cys with the addition of Cu(II) or Fe(III) ions. The results show that the oxidation rate of the thiols increases significantly when Cu(II) or Fe(III) ions are added to the system. It has also been found that TU and Cys can form stable complex compounds with the studied metal ions. The oxidation rates of the thiols are found to depend on the radiation intensity and emission spectrum of the irradiation sources.

Summary: The structure and electrochemical properties of zinc(II) complexes with a face-capping ligand have been investigated, revealing the effect of the ligand on bound semiquinonate (SQ) radicals. The substitution pattern of the SQ ring plays a crucial role in determining the fate of the bound SQ radicals. Additionally, the protective pocket formed by the ligand's phenyl substituents is unable to prevent decomposition of SQ radicals with minimal steric bulk, suggesting that substitution of the SQ ring is the main contributor to their stabilization.

Summary: In this article, the synthesis and characterization of copper, nickel, and palladium complexes bound by bidentate ligands derived from ortho-phenylenediamine are described. The complexes contain tunable H-bond donors and their crystal structures reveal intramolecular H-bonding interactions between the ligand scaffolds. Variations in the coordination sphere led to the isolation of the complexes in square-planar or twisted pseudo-tetrahedral geometries. Structural analysis showed that intramolecular H-bonding interactions can be altered by disrupting the bonds between countercations, solvent of crystallization, and ligand scaffold, resulting in changes in the geometry of the complexes. DFT calculations confirmed that Cu complexes prefer twisted geometries while Ni and Pd complexes favor square-planar geometries.
