Enhanced biological properties of taurine metal complexes via binding active sites

Abstract

A simple preparation of Taurine metal complexes (TauMC) were carried out by general precipitation technique using binary solvent (DMF-Water) in 1:1 ratio. Taurine-metal complex formation were confirmed by the shift in the absorption peaks of UV–Visible spectrum. The role of Taurine played as a vital ligand to form the series of metal complexes with transition metal ions (Mn, Cu, Zn) were clearly observed as the M-O stretching vibration in FT-IR spectroscopy. Thermal stability and crystalline structure of these taurine metal complexes were well characterized by TGA and XRD studies. Co-ordination complex ratio of metal to ligand (1:2) were absolutely determined via XPS analysis. Especially, among the prepared taurine based series of transition metal complexes, Taurine-Cu complex (TauCC) emerged out as binding active sites than ligand which significantly enhanced its biological properties.
