Item SYNTHESIS, STRUCTURE, AND BIOLOGICAL ACTIVITY OF COPPER(II), NICKEL(II), COBALT(III), AND IRON(III) COORDINATION COMPOUNDS WITH 2-{2-[(PROP-2-EN-1-YL)CARBAMOTHIOYL]HYDRAZINYLIDENE}PROPANOIC ACID(2020) Gulea, Aurelian; Graur, Vasilii; Diurici, E.; Ulchina, Ianina; Bouroș, Pavlina; Balan, Greta; Burduniuc, Olga; Țapcov, Victor; Rudic, Valeriu2-Oxopropanoic acid reacts in ethanol with N-(prop-2-en-1-yl)hydrazinecarbothioamide in a 1 : 1 mole ratio to form thiosemicarbazone H2L. Coordination compounds Cu(HL)X [X = Cl–, Br–, NO3–], Cu(H2O)(L), Ni(HL)2, Co(HL)2X [X = Cl–, Br–], and Fe(HL)2X [X = NO3–, Br–] are formed in the reactions of H2L with copper(II), nickel(II), cobalt(II), and iron(III) salts. The reactions of Cu(H2O)(L) with imidazole (Im) and 3,4-dimethylpyridine (3,4-Lut) result in mixed-ligand complexes Cu(A)(L) [A = Im, 3,4-Lut]. The structures of two copper complexes were determined by single crystal X-ray diffraction analysis. The synthesized complexes exhibit selective antimicrobial and antifungal activity in the concentration range of 15.62–1000 μg/mL. The introduction of amines into the inner sphere of copper complexes leads to an increase in the antimicrobial activity.Item SYNTHESIS, STRUCTURE, AND BIOLOGICAL ACTIVITY OF COORDINATION COMPOUNDS OF COBALT(II), NICKEL(II), AND COPPER(II) WITH N-(METHOXYPHENYL)-2-[(5-NITROFURYL)METHYLENE]HYDRAZINE CARBOTHIOAMIDES(2019) Gulea, Aurelian; Mitchevici, N.; Ciumacov, Iurie; Petrenko, Peter; Balan, Greta; Burduniuc, Olga; Țapcov, Victor4-(2-Methoxyphenyl)-, 4-(3-methoxyphenyl)-, and 4-(4-memoxyphenyl)-2-[(5-mttofuryl)methylene]-hydrazine carboxamide (HL1–3) react with hydrates of cobalt (nickel, copper) chloride (nitrate, acetate) with the formation of the M(HL1–3)2X2 (M = Co2+, Ni2+, Cu2+; X = Cl−, NO3−) and M(L1–3)2 (M = Ni2+, Cu2+) coordination compounds. Structure of the obtained compounds has been studied by means of X-ray diffraction analysis. Their antimicrobial and antifungal activity towards a series of Staphylococcus aureus, Escherichia coli, and yeast-like fungi standard strains has been investigated.
