Abstract

In this contribution, the synthesis and the reactivity with HS⁻ of a family of half-salen Zn complexes are reported. We provide evidence that HS⁻ binds the zinc center of all the complexes under investigation. DFT and CCSD(T) calculations were performed to model the reactivity of these complexes with HS⁻.

We successfully applied a homoleptic zinc complex bearing a Schiff-based ligand with pyridine pendant arms as a probe for the monitoring of exogenous and endogenous H₂S levels in live cells.

期刊介绍： The Journal of Inorganic Biochemistry is an established international forum for research in all aspects of Biological Inorganic Chemistry. Original papers of a high scientific level are published in the form of Articles (full length papers), Short Communications, Focused Reviews and Bioinorganic Methods. Topics include: the chemistry, structure and function of metalloenzymes; the interaction of inorganic ions and molecules with proteins and nucleic acids; the synthesis and properties of coordination complexes of biological interest including both structural and functional model systems; the function of metal- containing systems in the regulation of gene expression; the role of metals in medicine; the application of spectroscopic methods to determine the structure of metallobiomolecules; the preparation and characterization of metal-based biomaterials; and related systems. The emphasis of the Journal is on the structure and mechanism of action of metallobiomolecules.
