    Study of the β-Cyclodextrin Imipramine Hydrochloride Inclusion Complex and Determination of its Stability Constant (K) by UV-Visible Spectroscopy by Alamdar Ashnagar, Nahid Gharib Naseri, Bita Khanaki

    Published 2007-01-01
    “…In this research, the interactions of imipramine hydrochloride drug with β- cyclodextrin and the stability constant (K) of the inclusion complex formed between them were investigated by using UV-visible spectroscopy. Solutions consisting of a known and constant amount of imipramine hydrochloride and varying amounts of β- cyclodextrin were prepared in 0.1 M phosphate buffer (pH 7.4). …”

    «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

    Published 2025-01-01
    “…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. …”
