«Green-Ligand» in Metallodrugs Design—Cu(II) Complex with Phytic Acid: Synthetic Approach, EPR-Spectroscopy, and Antimycobacterial Activity by Kseniya A. Koshenskova, Natalia V. Makarenko, Fedor M. Dolgushin, Dmitriy S. Yambulatov, Olga B. Bekker, Matvey V. Fedin, Sergei A. Dementev, Olesya A. Krumkacheva, Igor L. Eremenko, Irina A. Lutsenko

“…The stability of <b>1</b> in the presence of human serum albumin (HSA) was investigated using Electron Paramagnetic Resonance (EPR) spectroscopy. Continuous wave (CW) EPR spectra in water/glycerol frozen solution clearly indicate a presence of an exchange-coupled Cu(II)-Cu(II) dimeric unit, as well as a Cu(II) monomer-like signal arising from spins sufficiently distant from each other, with comparable contributions of two types of signals. …”

Green Tea Polyphenol Epigallocatechin Gallate Interactions with Copper-Serum Albumin by Meiling Fu, Liangliang Zhang, Rick Killeen, Kenneth E. Onugwu, Robert M. McCarrick, Ann E. Hagerman

“…We proposed to determine whether EGCg binds or reacts with Cu(II)-serum albumin using fluorescence, UV–Visible and electron paramagnetic resonance (EPR) spectroscopy. Our results suggest that when serum albumin is loaded with Cu(II) in both sites, EGCg binds to the MBS-Cu(II) and reduces the copper to Cu(I). …”

Antioxidant Composition of a Selection of Italian Red Wines and Their Corresponding Free-Radical Scavenging Ability by Claudio Cassino, Valentina Gianotti, Federica Bonello, Christos Tsolakis, Maria Carla Cravero, Domenico Osella

“…The overall antioxidant capacity was determined by titrating a solution of the semistable free radical DPPH (1,1-diphenyl-2-picrylhydrazyl) with each wine sample followed by Electron Paramagnetic Resonance (EPR) spectroscopy and then measuring the resulting decrease in DPPH-signal. …”

Norfloxacin and N-Donor Mixed-Ligand Copper(II) Complexes: Synthesis, Albumin Interaction, and Anti-Trypanosoma cruzi Activity by Darliane A. Martins, Ligiane R. Gouvea, Gabriel S. Vignoli Muniz, Sonia R. W. Louro, Denise da Gama Jaen Batista, Maria de Nazaré C. Soeiro, Letícia R. Teixeira

“…The interaction of the copper(II) complexes with bovine serum albumin (BSA) and human serum albumin (HSA) was investigated using fluorescence quenching of the tryptophan residues and copper(II) EPR spectroscopy. The results of fluorescence titration revealed that copper(II) complexes have a moderate ability to quench the intrinsic fluorescence of the albumins through a static quenching mechanism. …”
