Summary: We have developed a novel biotin-targeted gold(I) complex with high selectivity and a unique mechanism for tumor targeting therapy. This complex shows remarkable inhibition of cancer cells and is more effective than the commonly used auranofin. It also acts as a potent radiosensitizer with selective anticancer effects. The complex intervenes in redox homeostasis and induces ferroptosis death, sensitizing tumor cells to radiotherapy.

Summary: In this study, we found that overexpression of TrxR2 enhances metabolic function and improves resistance to metabolic dysfunction induced by high-fat diet in mice. This effect is achieved through enhanced mitochondrial function, partly through improvements in the tricarboxylic acid cycle and electron transport chain. These findings demonstrate the important role of TrxR2 and mitochondrial thioredoxin in metabolic regulation.

Summary: A broad benchmarking of quantum mechanics (QM) protocols was conducted to predict the structure and reduction potential (epsilon o) of Pt(IV) complexes. The study discussed various factors such as basis set schemes, DFT methods, solvent effect, and conformational analysis for 11 distinct Pt(IV) complexes. Results showed that the structure was not highly sensitive to the QM protocol, with an average agreement of 3% with X-ray data. However, the reduction potential exhibited more significant sensitivity, with only a few QM protocols accurately within the 100 mV threshold. The protocol B3LYP/Pt-mDZP/jorge-DZP (P48) demonstrated the best performance, with a mean absolute deviation (MAD) of only 36 mV when considering conformers with higher electrophilicity. The P48 protocol was validated for three additional Pt(IV) complexes, resulting in a MAD of 24 mV.

Summary: In this study, computational protocols for predicting Co-59 NMR chemical shift were benchmarked. Quantum mechanical calculations based on density functional theory were used, along with NMR-DKH basis sets developed for all atoms, including Co. The best protocol involved geometry optimization at BLYP/def2-SVP/def2-SVP/IEF-PCM(UFF) and shielding constant calculation at GIAO-LC-ωPBE/NMR-DKH/IEF-PCM(UFF). This computational scheme was applied to a set of 34 Co(III) complexes with Co-59 NMR chemical shift ranging from +1162 ppm to +15,100 ppm, obtained in different solvents (water and organic solvents). The resulting mean absolute deviation (MAD), mean relative deviation (MRD), and coefficient of determination (R-2) were 158 ppm, 3.0%, and 0.9966, respectively, indicating an excellent alternative for studying Co-59 NMR.
