AB  - The condensation product of 7-acetyl-6-azaindole and Girard's T reagent ((E)-2-(2-(1-(1H-pyrrolo[2,3-c]pyridin-7-yl)ethylidene)hydrazineyl)-N,N,N-trimethyl-2-oxoethan-1-aminium, HL ligand) was used as a ligand in the reaction with Cu(BF4)2·6H2O and NaN3. The reaction led to the formation of a binuclear Cu(II) complex containing two end-to-end (di-m-1,3-N3) azide bridges, as well as two NNO-donor hydrazone ligands, forming an axially elongated square pyramidal geometry around each Cu(II) center. This end-to-end (di-m-1,3-N3) azide bridge binding mode has not yet occurred in Cu(II) complexes containing the NNO-donor hydrazone ligands, which makes the structure of the complex even more interesting for further studies. The complex was characterized by elemental analysis, IR spectroscopy and X-ray crystallography, and it was found that it crystallizes in the triclinic space group P–1 with the asymmetric unit comprising one Cu(II) centre, zwitterionic ligand L, one azide (N3−) ligand, and BF4− counter anion. Examination of antimicrobial activity of the complex shows higher antifungal and antibacterial activity towards tested Gram-positive bacteria in comparison to the hydrazone ligand, with the antifungal activity of the complex even being comparable to the activity of amphotericin B.
AB  - Кондензациони производ 7-ацетил-6-азаиндола и Жираровог Т реагенса (лиганд HL) коришћен је  као    лиганд у  реакцији са Cu(BF4)2·6H2O и NaN3.  Реакција је  довела до формирања бинуклеарног Cu(II)комплекса који садржи два азидна моста у „end-to-end“ (di-mu-1,3-N3) моду, као и два NNO-донорска хидразонска лиганда који заједно формирају аксијално издужену квадратно-пирамидалну геометрију око   сваког централног металног јона. Овај „end-to-end“ (di-mu-1,3-N3) азидни мост се до сада није појављивао у структурама бакар(II) комплекса који садрже NNO-донорске хидразонске лиганде, што чини структуру комплекса још   интересантнијом за  будућа испитивања. Овај    комплекс је  окарактерисан елементалном анализом, ИЦ   спектроскопијом и  рендгенском структурном анализом и пронађено је  да   кристалише у  триклиничној просторној групи P–1 са   асиметричном јединицом која се састоји из једног Cu(II)центра, цвитер-јонског лиганда (L), једног азидног лиганда (N3−) и BF4−контра-јона. Испитивање антимикробне активности комплекса показало је вишу антифунгалну активност, као и вишу антибактеријску активност према Грам-позитивним бактеријама, у односу на сам хидразонски лиганд, док је антифунгална активност комплекса чак упоредива са активношћу амфотерицина Б који је коришћен као стандард.

AB  - In this article, cytotoxicity, the mechanisms of cytotoxic activity, genotoxicity, and interaction with DNA and proteins, of two Cu(II) complexes with a salicylaldehyde derivative (4-(diethylamino)salicylaldehyde) and α-diimine (2,2′-bipyridine (bipy) and 1,10-phenanthroline (phen)) are reported. Both Cu(II) complexes performed cytotoxic effects against all tested malignant cell lines. Complexes exerted highest cytotoxicity against HeLa and A375 malignant cell lines. The cytotoxic activity of Cu(II) complex with phen as a α-diimine co-ligand was significantly higher in comparison with cytotoxic activity of Cu(II) complex with bipy. Pretreatment with specific inhibitors of caspase-3, caspase-8 or caspase-9, in order to clear up the mode of cell death triggered by two Cu(II) complexes in HeLa cells, indicated the ability of these complexes to induce apoptosis through activation of target caspases. Cu(II)-phen complex exhibited significant antioxidant activity compared with Cu(II)-bipy complex, and showed a better effect on reducing intracellular ROS levels in HeLa cells. Tested complexes did not display genotoxic potential in human peripheral blood leucocytes, but exhibited an antigenotoxic effect in post-treatment, after H2O2 exposure. The study of the in vitro biological properties regarding their affinity towards CT (calf-thymus) DNA and serum albumins showed that the compounds can intercalate to CT DNA, and bind reversibly and tightly to the albumins. Molecular docking studies of the ability of compounds to bind to biomacromolecules are consistent with in vitro studies.

AB  - In this article, synthesis, spectral and X-ray structure characterization, antimicrobial activity and Brine shrimp test of two new Cu(II) complexes with a salicylaldehyde derivative have been reported. Complexes [Cu(L)(bipy)]BF4·0.5H2O and [Cu2(L)2(phen)2](BF4)2 were obtained in the reaction of Cu(BF4)2·6H2O, deprotonated 4-(diethylamino)−2-hydroxybenzaldehyde ligand (L) and α-diimine (2,2’-bipyridine or 1,10-phenanthroline). The complex with bipyridine is mononuclear, containing one L and one bipyridine ligand in a distorted square-planar cation with a BF4 − anion and lattice water molecule, whereas the complex with phenanthroline is a dinuclear centrosymmetric dimeric cation, containing two L ligands along with two phenanthroline ligands and BF4 − anions. The coordination geometry of each Cu(II) ion can be described as an elongated square pyramid. MS-ESI spectroscopy indicated that [Cu2(L)2(phen)2](BF4)2 is mononuclear in DMSO solution. In vitro antibacterial and antifungal activity was tested against four Gram-positive, four Gram-negative bacteria and three fungal strains. Complexes showed significantly stronger antibacterial activities than parent ligands. The mononuclear phenanthroline complex in solution showed very good antimicrobial activity, which is comparable to the activity of the standard antibiotic amikacin against all tested bacterial strains. The same complex has better antifungal activity than fluconazole, which was used as a standard. Results of the brine shrimp test indicate that both complexes have good toxicity against Artemia nauplii.

abstract = "In this article, synthesis, spectral and X-ray structure characterization, antimicrobial activity and Brine shrimp test of two new Cu(II) complexes with a salicylaldehyde derivative have been reported. Complexes [Cu(L)(bipy)]BF4·0.5H2O and [Cu2(L)2(phen)2](BF4)2 were obtained in the reaction of Cu(BF4)2·6H2O, deprotonated 4-(diethylamino)−2-hydroxybenzaldehyde ligand (L) and α-diimine (2,2’-bipyridine or 1,10-phenanthroline). The complex with bipyridine is mononuclear, containing one L and one bipyridine ligand in a distorted square-planar cation with a BF4 − anion and lattice water molecule, whereas the complex with phenanthroline is a dinuclear centrosymmetric dimeric cation, containing two L ligands along with two phenanthroline ligands and BF4 − anions. The coordination geometry of each Cu(II) ion can be described as an elongated square pyramid. MS-ESI spectroscopy indicated that [Cu2(L)2(phen)2](BF4)2 is mononuclear in DMSO solution. In vitro antibacterial and antifungal activity was tested against four Gram-positive, four Gram-negative bacteria and three fungal strains. Complexes showed significantly stronger antibacterial activities than parent ligands. The mononuclear phenanthroline complex in solution showed very good antimicrobial activity, which is comparable to the activity of the standard antibiotic amikacin against all tested bacterial strains. The same complex has better antifungal activity than fluconazole, which was used as a standard. Results of the brine shrimp test indicate that both complexes have good toxicity against Artemia nauplii.",

AB  - In this work are presented the antioxidant activities of four copper(Il) complexes. Our complexes contain a combination of two types of ligands salicylaldehyde derivatives (methyl 3-formyl-4-hydroxybenzoate (HL1) or 4-(diethylamino)salicylaldehyde (HL2)) and a-diimines (bipyridine (bipy) or phenanthroline (phen)). Complex I is a dinuclear Cu* complex containing L1 and bipy ligands, complex 2 is dinuclear and contains L1 and phen ligands, complex 3 is a mononuclear Cu* complex containing L2 and bipy ligands, whereas complex 4 is dinuclear and containsL2 and phen ligands. Based on IC, values, it was established that complex 4 exhibits an excellent antioxidant activity, which is at the same time the highest among all four complexes (Table 1). Complex 3 exhibits moderate activity, whereas complexes 1 and 2 show the lowest antioxidant activity. All four complexes have better antioxidant activity than starting compounds

AB  - Two novel coppe(tr) complexes (Fig. 1) with 4-(diethylamino)salicylald.hyd. as ligand (HL) and o-diimine - 2,2'-bipyridine (bipy) or 1,lO-phenanthroline (phen) with potentially antimicrobial activity are described. Complex 1 is a mononuclear copper(Il) complex, [Cu(bipy)(L)]BF+.HzO, whereas complex 2 is a binuclear [Cu(phen)(L)]z(BF+)2. Antimicrobial activities of those complexes, coffesponding Cu(II) salt, o,-diimines (phen and bipy) and ligand HL were studied by examining the minimum inhibitory concentration (MIC) on four Gram-positive and four Gram-negative bacterial species and three fungal strains. Amikacin and fluconazole were used as the standard drugs for the comparison of the MIC values. Cu(II) complexes I and 2 demonstrated significantly stronger antibacterial activities than parent ligands (adiimines and HL) or starting Cu(II) salt. Complex 2 is the most active of all examined compounds. The activity of this complex against E. coli is comparable to the activity of the standard antibiotic amikacin. Unlike increasing antibacterial activity of complexes 1 and2 in regard to all coordinated ligands, antifungal activities showed the opposite trend.
