AB  - A Schiff base of 3-acetylpyridine with semicarbazide as well as the corresponding tetrahedral Zn(II) complex were synthesized and characterized by X-ray crystal structure analysis and spectroscopic methods. It is interesting to note that the ligand coordinated as a monodentate although there are several donor atoms in it. Computational studies showed that such structure is more stable than the hypothetical structure with one ligand bound as a bidentate. The complex exibited moderate antibacterial, antifungal and cytotoxic activities while the ligand was mostly inactive. The complex strongly induced formation of reactive oxygen species in tumor cell lines. It also influenced cell cycle progression in tumor cell lines, and induced autophagy. The latter effect is, at least in part, a protective one.

AB  - Five new dioxomolybdenum(VI) complexes of the general formula [MoO2(Rdtc)2], 1-5, where Rdtc- refer to piperidine (Pipdtc), 4-morpholine (Morphdtc), 4-thiomorpholine (Timdtc), piperazine (Pzdtc) or N-methylpiperazine (N-Mepzdtc) dithiocarbamates, respectively, have been prepared. The complexes were characterized by elemental analysis, conductometric measurements, electronic, IR and NMR spectroscopy. The complexes 1-5 contain a cis-MoO2 group and have an octahedral geometry. Two dithiocarbamato ions join as bidentates with both the sulfur atoms to the molybdenum atom. The presence of different heteroatoms in the piperidino moiety influences the v(C=N) and v(C=S) vibrations, which wavelengths decrease in the order: Pipdtc > N-Mepzdtc > Morphdtc > Pzdtc > Timdtc ligands. Based on their spectral data, the molecular structures of complexes 1-5 were optimized at the semi-empirical molecular-orbital level, and the geometries, as obtained from calculations, are described. The antimicrobial activities of the complexes were tested against nine different laboratory control strains of bacteria and two strains of the yeast Candida albicans. All the tested strains were sensitive. Complexes bearing heteroatom in position 4 of piperidine moiety were significantly more potent against the tested bacteria compared to the corresponding ligands.
AB  - Sintetisano je pet novih dioksomolibden(VI) kompleksa, opšte formule [MoO2(Rdtc-)2], sa Rdtc- ligandima: piperidin- (Pipdtc), 4-morfolin- (Morphdtc), 4-tiomorfolin- (Timdtc), piperazin- (Pzdtc) i N-metilpiperazin- (N-Mepzdtc) ditiokarbamatima. Kompleksi su okarakterisani elementalnom analizom, IR i NMR spektroskopijom kao i merenjem molarne provodljivosti. Pretpostavljena geometrija svih kompleksa je oktaedarska. Rdtc- ligandi su bidentatno koordinovani preko oba atoma sumpora za atom molibdena. Prisustvo različitih heteroatoma utiče na promenu položaja v(C=N) i v(C=S) vibracija, čiji opada sledećim redom liganada: Pipdtc > N-Mepzdtc > Morphdt > Pzdtc > Timdtc. Na osnovu spektralnih podataka, strukture svih kompleksa su optimizovane na semiempirijskom molekulsko-orbitalnom nivou upotrebom PM6 metoda. Antimikrobna aktivnost ispitivana je na jedanaest različitih patogena. Uočeno je da kompleksi koji imaju heteroatom u položaju 4 piperidinskog prstena ispoljavaju značajno veću jačinu antimikrobnog dejstva prema bakterijama, u poređenju sa odgovarajućim ligandima.

The equilibrium constants were determined potentiometrically at 25°C at a constant ionic strength of 0.10 mol/dm3 (Na2SO4). The results showed that at pH  lt  8 both the Fe(III) complexes studied here have three, while [Zn(L1)(H2O)3]+ and [Zn(L2)(H2O)2]2+ have one and two titratable protons, respectively. Based on the obtained values for the equilibrium constants, protonation schemes of the examined complexes are proposed.

AB  - In this paper the first complexes of M2+ ions (M2+ = Zn2+, Cd2+ and Co2+) with N-benzyloxycarbonyl-S-phenylalaninato ligand (1-3) are described. The new complexes were characterized by means of elemental analysis, IR and UV-vis spectroscopy, molar conductivity measurements and H-1, C-13 and N-15 NMR spectroscopy (1D and 2D). The Co(II) complex adopts an octahedral geometry, and the Zn(II) and Cd(II) complexes adopt a tetrahedral one. For the first time, the antimicrobial activity of N-benzyloxycarbonyl-S-phenylalaninato ligand (N-Boc-S-phe) and the complexes 1-3 was investigated against Gram-positive: Micrococcus luteus, Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis and Bacillus subtilis and Gram-negative bacteria: Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and two strains of the yeast Candida albicans. It was shown that the complexes were effective against most strains. The best activity was detected against the yeast C. albicans.
