    MICROMOLECULAR INHIBITORS OF SUPEROXIDE RADICALS
    (2021) Andronache, Lilia; Pantea, Valeriana; Gulea, Aurelian; Șveț, Inna; Graur, Vasilii; Matcovschi, Valerii; Gamaniuc, Marina; Gudumac, Valentin
    Background: Currently, there is a growing interest in new copper (Cu2+) heterocyclic coordination compounds (CC), isothiosemicarbazide derivates, which demonstrated multiple beneficial properties, but their effect on reactions with free radicals such as the superoxide radical has not been investigated. Material and methods: The action of new micromolecular complexes of copper (Cu2+) chloride and bromide with methyl n- (prop-2-en-1-yl) -2- (pyridin2-ylmethylidene) hydrazine carbimidothioate on capturing activity of the superoxide radical was determined by the spectrophotometric method in vitro experiments. Results: It was established that the micromolecular complexes of copper (II) chloride and bromide with methyl n-(prop-2-en-1-yl)-2-(pyridin-2ylmethylidene) hydrazine carbimidothioate have been found to possess strong superoxide radical inhibitor properties when interacting with a superoxide radical. In addition to this, the IC50 of the studied compounds depends on the nature of the acid-ligand in the internal sphere of the complex and increases in the following sequence: Cl-–Br-. Conclusions: The established property of mentioned compounds is new, because their use as micromolecular inhibitors of superoxide radicals has not been described so far. The synthesized CC expand the arsenal of superoxide radical inhibitors with high biological activity. Their possible significance for the development of new treatment strategies for diseases associated with the overproduction of superoxide radicals is discussed.

    (Marina Sokolova Publishings, 2022) Gulea, Aurelian; Tsapkov, Victor; Graur, Vasilii; Pantea, Valeriana; Andronache, Lilia; Shvets, I.; Matusovsky, V.; Lisii, D.; Botnaru, M.; Gudumac, Valentin
    New biologically active coordination compounds of copper(II) based on substituted 3-(phenyl)-1-(pyridin-2-yl)prop-2-en- 1-one 4-allylthiosemicarbazones have been obtained. It was found that these compounds exhibit strong antiradical properties when interacting with a superoxide radical. Due to this property, the obtained compounds can find wide application in medicine as inhibitors of superoxide radicals in the human body, thus preventing damage of cells and tissues, multifactorial diseases, including carcinogenesis. The synthesized coordination compounds expand the arsenal of superoxide radical inhibitors with high biological activity. Their possible significance for the development of new treatment strategies for diseases associated with the overproduction of superoxide radicals discussed.
