    SYNTHESIS, STRUCTURE, AND BIOLOGICAL ACTIVITY OF MIXED-LIGAND AMINE-CONTAINING COPPER(II) COORDINATION COMPOUNDS WITH 2-(2-HYDROXYBENZYLIDENE)-N-(PROP-2-EN-1-YL)HYDRAZINE- CARBOTHIOAMIDE
    (2021) Gulea, Aurelian; Graur, Vasilii; Ulchina, Ianina; Bouroș, Pavlina; Smaglii, Vadim; Garbuz, Olga; Țapcov, Victor
    Сopper(II) nitrate reacts in ethanol with 2-(2-hydroxybenzylidene)-N-(prop-2-en-1-yl)hydrazinecarbothioamide H2L in an 1 : 1 molar ratio to form the coordination compound Cu(HL)NO3·H2O. The introduction of amines [imidazole (Im), 3,5-dibromopyridine (3,5-Br2Py), and 4-methylpyridine (4-Pic)] into the reaction mixture in a molar ratio 1 : 1 : 2 leads to the formation of CuA(HL)NO3·nH2O [A = Im, 3,5-Br2Py, 4-Pic; n = 0, 3] complexes. The structure of the obtained compounds was determined by X-ray structural analysis. The synthesized complexes exhibit antimicrobial, antifungal, antioxidant, and anticancer activities.

    NICKEL(II) COMPLEXES WITH PENTANE-2,4-DIONE BIS(4-ALLYLTHIOSEMICARBAZONE)
    (2020) Gulea, Aurelian; Graur, Vasilii; Ciumacov, Iurie; Petrenko, Peter; Garbuz, Olga; Țapcov, Victor; Gudumac, Valentin
    Reaction of pentane-2,4-dione with N-(prop-2-en-1-yl)hydrazinecarbothioamide at a 1: 2 molar ratio in ethanol resulted in the formation of a pyrazole derivative. The latter reacted with nickel perchlorate at a 1: 1 molar ratio to form the nickel complex with pentane-2,4-dione bis(4-allylthiosemicarbazone). The same type of nickel complex was obtained as a result of N-(prop-2-en-1-yl)hydrazinecarbothioamide reaction with pentane-2,4-dione and nickel nitrate at a 2: 1: 1 molar ratio. Antimicrobial, antifungal, antioxidant, and anticancer activities of the obtained compounds were studied.

    SINTEZA ȘI CERCETAREA PROPRIETĂȚILOR FARMACOFORE ALE UNOR N-(DIMETILFENIL) HIDRAZINCARBOTIOAMIDE
    (2023) Erhan, Tatiana; Garbuz, Olga; Ungur, Nicon; Gulea, Aurelian
    The present study was focused on the synthesis of some N-(dimethylphenyl)hydrazine carbothioamides 1-4, that contain the following N-substituents: 2,4-dimethylphenyl; 2,5-dimethylphenyl; 2,6-dimethylphenyl; 3,4-dimethylphenyl, to increase lipophilicity and N-(dimethylphenyl)-2-(pyridin-2-ylmethylidene)hydrazinecarbothioamides 5-8, analogous of Triapine. The structural formula of the compounds was characterized by means of spectroscopy: FT-IR, 1H-, and 13CRMN, and the molecular structure, for the first time, by means of X-ray diffraction. The study of antioxidant activity has shown that all compounds 1-8 are powerful antioxidants. N-(dimethylphenyl)-2-(pyridin2-ylmethylidene)hydrazinecarbothioamides 5-8 were tested as inhibitors of MCF-7 (breast cancer) cell proliferation. It was found that all the compounds exhibit activity comparable to that of Doxorubicin, among them the compound N-(2,5-dimethylphenyl)-2-(pyridin-2-ylmethylidene)hydrazinecarbothioamide 6, with IC50=0.8 μM/L, demonstrated the highest activity.

    IN VITRO ANTICANCER ACTIVITY OF CHLORO(N-PHENYL-N'-[(PYRIDIN-2- YL)METHYLIDENE]CARBAMOHYDRAZONOTHIOATO) (4-AMINOBENZENE-1-SULFONAMIDE)COPPER
    (CEP USM, 2018) Garbuz, Olga
    This study was aimed to evaluate the antiproliferative activity of the mixed-ligand complex (chloro(N-phenyl-N'- [(pyridin-2-yl)methylidene]carbamohydrazonothioato)(4-aminobenzene-1-sulfonamide)copper) on several cancer cells of lines. It was established, that the copper(II) mixed-ligand complex exhibits the highest anticancer activity against MeW-164, HeLa, BxPC-3 and RD cells of lines with IC50 values of 1.0±0.2, 0.4±0.04, 1.7±0.2, 1.3±0.3 µM, respectively. A comparative study between the tested compound and DOXO in regard to cancer lines has established that the tested copper(II) mixed-ligand complex exhibits stronger inhibitory activity on cancer cells proliferation than doxorubicin and cisplatin.

    SINTEZA UNOR TIOSEMICARBAZONE ÎN BAZA N-{4-(HIDRAZINILCARBONOTIOIL)AMINO]FENIL}ACETAMIDEI
    (CEP USM, 2016) Rusnac, Roman; Rusnac, Anna; Garbuz, Olga; Babară, Nicanor; Gulea, Aurelian; ;
    În articol sunt descrise metodele de sinteză a şase compuşi organici, dintre care trei nu sunt cunoscuţi în literatura de specialitate. Structura compuşilor a fost eterminată cu ajutorul spectroscopiei: RMN 1H,13C şi IR. A fost studiată activitatea anticancer pe celule HeLa (cancer cervical), unde compusul N-[4-({2-[1-(piridin-2-il etltiliden]hidrazincarbotioil}amino) fenil]acet-amidă a prezentat cea mai mare pondere de inhibiţie (84%) la concentraţia de 100 μM/L.
