Summary: The diiron active site plays a crucial role in catalytic transformations in both biological and chemical systems. Recent advancements in the field include the synthesis of biomimetic diiron catalysts inspired by the active structure of soluble methane monooxygenase (sMMO), which have been successfully applied to the dehydrogenation of indolines.

Summary: Many proteins require a metal cofactor for their function, and these metals play a role in protein folding. The study found that the metallation rates of different metal binding pathways are influenced by pH, with the less cooperative pathway being more affected by low pH conditions. Specific mixtures of structures are formed in the initial steps of metallation, and unfolding the disordered apo-MT structure hinders the formation of these preliminary structures. The compact conformation of the native apo-MT allows for rapid formation of metal-thiolate structures with high affinity, providing protection from oxidation.

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: Three BODIPY-Ru(II) complexes were synthesized by coordinating [Ru(bpy)2Cl]+ complexes to BODIPY ligands. The spectroscopic and electrochemical properties of the complexes were characterized. The complexes exhibited intense absorption peaks due to the pi pi* transitions localized on the BODIPY core, and additional charge transfer transitions associated with the metal center. The complexes showed significant singlet oxygen generation and were able to induce photo-nicking of DNA.

Summary: Isomorphous series are generated by replacing atoms or molecules to form materials with similar compositions. They allow modulation of structure and properties, and generate equivalent compositions with novel material properties. The study of stereo-electronic aspects of different equivalent compositions can improve the utility of the original composition.

Summary: Two new Np(V) o-Cl-benzoates complexe, [(NpO2)(phen)(C7H4ClO2)]3 (1) and [(NpO2)(bipy)(C7H4ClO2)]4·2H2O (2), with N-donor ligands phenantroline (phen) and bipyridine (bipy), have been synthesized and characterized. The structures of the complexes reveal the formation of trimeric and tetrameric complexes, with NpO2+ cations linked by cation-cation bonds acting as monodentate ligands. The electronic absorption spectra of the crystalline compounds were measured in the near IR-visible range.
