Item SYNTHESIS, STRUCTURE AND BIOLOGICAL ACTIVITY OF N(4)-ALLYL-3-THIOSEMICARBAZONES AND THEIR COORDINATION COMPOUNDS WITH SOME 3D METALS(CEP USM, 2015) Graur, VasiliiThe paper presents a review of different N(4)-allyl-3-thiosemicarbazones and their coordination compounds described in literature. N(4)-allyl-3-thiosemicarbazide can form corresponding thiosemicarbazones with aliphatic, aromatic and heteroaromatic carbonyl compounds. In the presence of transitional metal ions they can form coordination compounds of different structures. Both coordination compounds and proligands manifest antitumor, antibacterial, antiviral, and antimalarial activities. Copper(II) coordination compounds with these ligands manifest better antitumor activity than corresponding proligands.Item SYNTHESIS AND BIOLOGICAL ACTIVITY OF NICKEL AND COPPER COORDINATION COMPOUNDS OF 5-NITROFURAN-2-CARBALDEHYDE N(4)-ALLYL-3-THIOSEMICARBAZONE(CEP USM, 2014) Graur, Vasilii; Zariciuc, Elena; Tsapkov, Victor; Barba, Nina; Gulea, AurelianThe paper presents the synthesis of the ligand 5-nitrofuran-2-carbaldehyde N(4)-allyl-3-thiosemicarbazone (HL) and eight coordination compounds of copper(II) and nickel(II) with this ligand. The structure of thiosemicarbazone HL was studied using 1 H and 13С NMR spectroscopy. For the synthesized compounds their antimicrobial and antifungal activity was studied on a series of standard strains. For HL and Cu(HL)2(NO3)2 the antitumor activity towards human leukemia HL-60 cells was estimated. It was established that coordination compounds manifest better activity than free ligand.
