Summary: The investigation of the interaction between metal ions and DNA has always been a topic of great interest in the fields of bioinorganic chemistry, supramolecular coordination chemistry, and DNA nanotechnology. The interaction can be divided into non-specific electrostatic adsorption and specific covalent binding. This article focuses on the mechanism of action between Ag+ and DNA mismatch pair C-C, and summarizes the characterization methods and applications. It aims to provide a reference for the field of biological devices. The development of cryo-electron microscopy and liquid-cell TEM is expected to further characterize the structure of C-Ag+-C and enhance its application.

Summary: Ammonium trichloro (dioxoethylene-O,O ') tellurate (AS101) is a potential therapeutic prodrug with immunomodulatory properties. This study investigates the activation process of AS101 and its analogues in the presence of water. The results demonstrate that water triggers the conversion of AS101 to the pharmacologically active species, and the effect is influenced by the halogens present. The study provides valuable insights into the chemical and mechanistic implications of AS101 activation.

Summary: A series of five decavanadate complexes were successfully synthesized using a one-pot synthesis. The structures and properties of these complexes were studied, and it was found that 1 and 3 are decavanadato complexes, while 2, 4, and 5 are decavanadate complex salts. The binding to model proteins, cytotoxicity, and water oxidation catalysis were investigated, and it was observed that 1 showed higher activity in water oxidation catalysis and lower cytotoxicity compared to the uncoordinated V-10.

Summary: The generated databases (GDBs) list billions of possible molecules through systematic enumeration following simple rules of chemical stability and synthetic feasibility. The originality of GDB molecules can be assessed by comparing their Bemis and Murcko molecular frameworks (MFs) with those in public databases. This comparison revealed that GDB-13s MFs had diverse ring sizes and ring systems without linker bonds, making them attractive targets for synthetic chemistry aiming at innovative molecules.

Summary: The antiproliferative activity of three clinically used antibiotics (CIP·HCl, PEN·Na, and TC·HCl) was studied through DNA inhibition mechanisms using ex vivo, in silico, and in vitro methods. The binding interactions of the antibiotics with DNA were determined through UV-Vis spectra and viscosity measurements, and their binding constants (K-b) were calculated. Docking studies were performed to explain the ex vivo results. The in vitro antiproliferative activity of the antibiotics was evaluated against MCF-7 cells, and the toxicity was tested against MRC-5 cells. TC·HCl and CIP·HCl exhibited significant antiproliferative activity and low toxicity despite their low binding affinity to DNA or different mode of interaction.

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.
