AB  - In this paper, the previously synthesized Cu(II) complex ([CuL1(N3) (CH3OH)]BF4) with N,N,N-trimethyl-2-oxo-2-(2-(1-(thiazol-2-yl)ethylidene)hydrazinyl)ethan-1-aminium chloride, has been characterized and its biological activity has been studied in detail. The Cu(II) complex consists of ligand coordinated in a deprotonated, formally neutral zwitter-ionic form, via NNO atoms, one azido ligand and one methanol molecule. The Cu(II) complex was selected due to results of the cytotoxic activity, the brine shrimp test and DPPH radical scavenging activity, which were previously performed. The effects of Cu(II) complex on cell cycle phase distribution of cervical adenocarcinoma HeLa cells were investigated in order to examine the mechanisms of its anticancer activity. The measurement of intracellular ROS levels in HeLa and HaCaT cell lines were evaluated in order to explore their possible generation and the role in cytotoxic activity. The possible anti-invasive and anti-angiogenic properties of Cu(II) complex were evaluated. DNA binding experiments, including fluorescence displacement study and DNA cleavage experiments, were performed in order to obtain information on the type of DNA-metal complex interactions. © 2022 Serbian Chemical Society.

AB  - Nickel acetate tetrahydrate (NAT) sample series were used to modify screen-printed carbon electrodes (SPCE). The samples were hybrid Ni/NiO nanocomposites, where the NiO phase increased with an applied treatment temperature. Results of electrochemical measurements pointed that the Ni/NiO550/SPCE-modified electrode had the best analytical performance toward the detection of riboflavin (RF). The Ni/NiO550/SPCE-based sensor showed linear response with RF in the concentration range of 0.5–75 μM and 0.15 μM LOD in BRBS. Sensor offered fast response time, good repeatability, and selectivity with an RSD of 1.4 %. Our results show that the Ni:NiO nanocomposite ratio strongly influenced the electroanalytical performance of SPCE.

AB  - Materials sensitive to external stimuli are recognized as safe and effective tool able to respond to specific demands in the therapy of various diseases. Thermo sensitive hydrogels based on poly(N-isopropylacrylamide) (P(NIPAAM)) are widely investigated for targeted drug delivery. Still, the abundance of the stimuli in the human body often requires more than one responsive group able to act simultaneously to achieve optimal therapeutic effects. Due to its pH sensitivity and bio-based production, crotonic acid (CA) was a monomer of choice for preparation of eco-friendly copolymer hydrogels based on NIPAAM and CA (P(NIPAAMcoCA)), which turned to be thermo and pH sensitive at the same time. The potential of the P(NIPAAMcoCA) system for encapsulation and controlled release of drugs with different solubility was investigated engaging water-soluble lidocaine hydrochloride and poorly water-soluble ibuprofen as model drugs. The hydrogels were characterized by various technics: FTIR, DSC, SEM and single compressive tests, while swelling behavior and controlled release of the drugs were analyzed with respect to the CA amount in two environments with different pH values at 25 °C and 37 °C. It was demonstrated that due to their dual responsiveness the P(NIPAAMcoCA) hydrogels have potential for controlled release of drugs with different solubility.

AB  - The aim of this study was to examine the influence of shoot age on the biological and chemical properties of 13 black currant cultivars with different origins and ripening times. Pheno-logical observations together with examined pomological and chemical characteristics were studied in two consecutive years at the experimental field near Belgrade, Serbia. The total content of phenols was estimated spectrophotometrically by the Folin-Ciocalteu method, while quantitative analysis of anthocyanin and flavonols aglycones was performed using a high-performance liquid chromato-graphic (HPLC) method. Principal component analysis was performed to establish differences in biological and chemical properties of black currants. Three-year-old shoots had an earlier start of all examined phenological stages, better generative potential, higher yields, while clusters and berries from 2-year-old shoots had significantly higher values for physical properties, total phenols, anthocyanin and flavanols aglycones and antiradical capacity. Late ripening cultivars had higher contents of all chemical compounds. The berries on 2-year-old shoots had total phenolics that ranged between 123.0 (‘Titania’) and 298.3 mg/100 g fresh weight (FW) (‘Ometa’), while total antho-cyanins ranged between 398.5 (’Ojebyn’) and 1160.8 mg/kg FW (’Ometa’). According to the obtained results, cultivars ‘Ometa’, ‘Ben Lomond’, ‘Tsema’ and ‘Malling Juel’ can be recommended as the most promising for growing in the continental climate because they stood out with higher generative potential and yield, physical traits of cluster and berry, higher level of primary and secondary metabolites and DPPH activity in their berries.

AB  - According to recent research, even low levels of environmental chemicals, particularly heavy metals, can considerably disrupt placental homeostasis. This review aims to explore the profile of non-essential trace metals in placental tissues across the globe and to specify trace metal(s) that can be candidates for impaired placental health. Accordingly, we conducted an extensive survey on relevant databases of peer-reviewed papers published in the last two decades. Among a considerable number of non-essential trace metals, arsenic (As), lead (Pb), cadmium (Cd), and mercury (Hg) were identified as the most detrimental to placental health. Comparative analysis showed remarkable differences in placental levels of these trace metals worldwide. Based on current data reported across the globe, a median (min–max) range from 0.55 to 15 ng/g for placental As levels could be deemed safe. The placental Cd and Pb levels were markedly higher in smokers than in non-smokers. Occupationally exposed pregnant women had several orders of magnitude higher Cd, Pb, and Hg levels in placental tissues than non-occupationally exposed women. Also, we concluded that even low-level exposure to As, Cd, Pb, and Hg could be deleterious to proper fetal development. This review implies the need to reduce exposure to non-essential trace metals to preserve placental health and prevent numerous poor pregnancy outcomes. Overall, the information presented is expected to help plan future fundamental and applied investigations on the placental toxicity of As, Cd, Pb, and Hg. © 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.

AB  - Lavandula sp. essential oil and hydrolate are commercially valuable in various industry branches with the potential for wide-ranging applications. This study aimed to evaluate the quality of these products obtained from L. x intermedia cv. ‘Budrovka’ for the first time cultivated on Fruška Gora Mt. (Serbia) during three successive seasons (2019, 2020, and 2021). Essential oil extraction was obtained by steam distillation, and the composition and influence of weather conditions were also assessed, using flowering tops. The obtained essential oils and hydrolates were analysed by gas chromatography with a flame ionization detector (GC-FID) and gas chromatography coupled to mass spectrometry (GC-MS). A linear regression model was developed to predict L. x intermedia cv. ‘Budrovka’ essential oil volatile compound content and hydrolate composition during three years, according to temperature and precipitation data, and the appropriate regression coefficients were calculated, while the correlation analysis was employed to analyse the correlations in hydrolate and essential oil compounds. To completely describe the structure of the research data that would present a better insight into the similarities and differences among the diverse L. x intermedia cv. ‘Budrovka’ samples, the PCA was used. The most dominant in L. intermedia cv. ‘Budrovka’ essential oil and hydrolate were oxygenated monoterpenes: linalool, 1,8-cineole, borneol, linalyl acetate, and terpinene-4-ol.

abstract = "Lavandula sp. essential oil and hydrolate are commercially valuable in various industry branches with the potential for wide-ranging applications. This study aimed to evaluate the quality of these products obtained from L. x intermedia cv. ‘Budrovka’ for the first time cultivated on Fruška Gora Mt. (Serbia) during three successive seasons (2019, 2020, and 2021). Essential oil extraction was obtained by steam distillation, and the composition and influence of weather conditions were also assessed, using flowering tops. The obtained essential oils and hydrolates were analysed by gas chromatography with a flame ionization detector (GC-FID) and gas chromatography coupled to mass spectrometry (GC-MS). A linear regression model was developed to predict L. x intermedia cv. ‘Budrovka’ essential oil volatile compound content and hydrolate composition during three years, according to temperature and precipitation data, and the appropriate regression coefficients were calculated, while the correlation analysis was employed to analyse the correlations in hydrolate and essential oil compounds. To completely describe the structure of the research data that would present a better insight into the similarities and differences among the diverse L. x intermedia cv. ‘Budrovka’ samples, the PCA was used. The most dominant in L. intermedia cv. ‘Budrovka’ essential oil and hydrolate were oxygenated monoterpenes: linalool, 1,8-cineole, borneol, linalyl acetate, and terpinene-4-ol. It is established that the temperature was positively correlated with all essential oil and hydrolate compounds. The precipitations were positively correlated with the main compounds (linalool, 1,8-cineole, and borneol), while the other compounds’ content negatively correlated to precipitation.

The compounds were obtained in MeOH from corresponding metal salts and LH2 in molar ratio 1:1 and further characterized by mass spectrometry, IR spectroscopy, electrochemistry, and elemental analysis. Previously reported copper(II) analog, ([Cu2(LH)2]·(ClO4)2, 3) was joined to 1 and 2, and the three metal analogs, 1-3, were further investigated in terms of their electrochemical behavior. The binding studies of the complexes with deoxyribonucleic acid (DNA) and human serum albumin (HSA) were carried out using both spectrophotometric and electrochemical methods. All three complexes exhibit binding affinity towards the DNA chain through intercalative interaction. The binding reaction with HSA showed for 1 and 3 complexes decrease in the peak current obtained in the case of complexes before the addition of HSA, while resulted compound obtained from Ni complex – HSA possesses the same electroactivity as starting complex. Furthermore, the cytotoxicity of LH2 as well as its metal complexes, and cisplatin were evaluated on CT-26 mouse colon carcinoma and human LS174T cancer cell lines employing MTT assay. The copper(II) complex exhibited very promising anticancer activity compared with cisplatin.

AB  - Heavy metals are naturally occurring elements, but they are regarded as significant environmental pollutants due to their high density and high toxicity even at low concentrations. The aim of this paper is the evaluation of the pollution level of heavy metals in the river and riverbank sediments, as well as the estimation of their origin and spatial differences along the course of the Vrbas River through Banja Luka. The concentrations of metals have been assessed using the Inductively coupled plasma – optical emission spectrometry and Advanced mercury analyzer for mercury determination. The anthropogenic impact on heavy metal concentration in sediments was estimated by the calculating of pollution indices: geoaccumulation index (Igeo), contamination factor (Cf), pollution load index (PLI) and potential ecological risk index (Er). Obtained results indicate that there is no statistically significant spatial difference in metal concentration, indicating that heavy metals in sediments have a constant source. The anthropogenic impact expressed by the values of pollution indices showed that sites are generally uncontaminated by Co, Cr and V and moderately contaminated by Zn, Cu and Ni. On the contrary, lead, mercury and cadmium pose the highest ecological risk. The anthropogenic source of Pb, Hg and Cd is industry, municipal waste and the combustion of fossil fuels. The obtained results demonstrate the high ecological risk and the need for environ-mental monitoring, with the aim to support an efficient strategy to reduce local pollution and contamination of the investigated system.

AB  - Biological markers (BMs) are organic compounds in oils in which a precursor is known, and during the transformation of organic matter these compounds undergo certain structural and stereochemical changes. Based on the established precursors of BMs, the origin of the examined oils can be estimated, and based on the intensity and the type of changes and also geological history. It includes defining the deposition medium, the degree of maturation, the length of the oil migration path, the degree of biodegradation. The most studied and applied BMs are normal alkanes, isoprenoid aliphatic alkanes pristane and phytane, and polycyclic alkanes of the sterane and terapane type. On the other hand, in the environmental chemistry, these compounds can significantly contribute to the identification of petroleum pollutants, as well as to the assessment of the migration mechanism and the intensity of biodegradation.

AB  - Abstract
Purpose The Great War Island (GWI) is a landform of exceptional features and a protected area located in the center of
Belgrade at the Sava and Danube River’s confluence. The position of GWI causes a large number of possible hydrocar-
bons inputs that influence the quality of both river waters and sediments. The main objective of this research is to assess
the distribution and source of hydrocarbons in sediments deposited at the GWI depending on the river’s flow regimes and
depositional environment.
Material and methods Sediment samples were collected from 16 sites (11 sites along the GWI’s coast, 4 sites from the
inner of the Island, and 1 specific wetland site). The grain size was determined using a standard wet sieving procedure. The
extractable organic matter (OM) was quantified after Soxhlet extraction, and aliphatic and aromatic fractions were isolated
by column chromatography. n-Alkanes, diterpanes, terpanes, steranes, and 16 PAHs are analyzed by gas chromatography-
mass spectrometry.
Results and discussion Sand fraction predominates in coastal samples, and clay size fraction in the samples from the inner
island environment. The predominance of odd higher n-alkanes indicates the terrestrial origin of OM, while the distribution
of lower n-alkanes indicates a certain proportion of algae, bacteria, and/or high maturity of OM. The presence of oil-type
pollutants is confirmed by thermodynamically stable biomarker isomers and/or the presence of unresolved complex mixture
(UCM). Inner island samples are characterized by the largest amount of Corg (up 6%), indicating high bioproductivity and
good preservation of OM. Samples from wetland environment are distinguished by the domination of pimaranes and phyl-
locladanes among saturated hydrocarbons.
Conclusions This study revealed that sediments of the GWI mainly contain native OM with a certain anthropogenic input.
The native OM predominately comes from higher terrestrial plants (Salix alba, Populus nigra, Fraxinus viridis, Taxodium
distichum Rich.), followed by various types of grasses, macrophytes (Salvinia natans, Nymphaea alba), bacteria, algae, and
phytoplankton. Anthropogenic OM originates from petroleum, but also combustion products arrived by deposition from
the air and runoff.

AB  - In the last decades online communication has become an important part of the education. In the conditions caused by the COVID-19 pandemic it has become significant since it was necessary to switch to some forms of online teaching/learning. The aim of this research study was to compare the effects of the application of internet pages for independent online asynchronous learning outside the school (group A) and face-to-face instruction realized by a teacher at school (group B). The content of the internet pages was created in order to enable the acquisition of the concepts of solutions and dissolution in the seventh grade of primary school. The effects of the approaches were studied based on the student achievement in a post-test (immediately upon learning) and in a delayed post-test (a year after the applied approaches). The participants in this research study were 187 primary school students. There was not a statistically significant difference between the overall achievements of the students who learnt about solutions and dissolution by independent asynchronous online learning and face-to-face learning at school.

Both cell lines are characterized by a highly invasive and resistant phenotype. Drug combination studies inPANC-1 cells with C1 and Verapamil hydrochloride (VRP), which is the established inhibitor of efflux transporterP-glycoprotein (Pgp), revealed enhancement of antiproliferative action of the complex in a dose-dependentmanner, and slight arrest of cell cycle in the S phase. Also, a depletion of the glutathione (GSH) level by Lbuthionine-sulfoximine (L-BSO) at sub-toxic concentrations (100 μM) caused an increase of activity of C1 to theIC50 57.67 ± 6.51 (μM). A morphological analysis in PANC-1 cells by dual acridine orange/ethidium bromidestaining, revealed apoptotic potential of complex C1 and a slower kinetic of cell death induction, suggesting adifferent mechanism of action compared to cisplatin.

the Covid-19 pandemic it has become particularly significant since in most
cases it was necessary to switch to some forms of online teaching-learning.

the effects of the application of internet pages for independent online asyn-
chronous learning outside the school environment (group A) and face-to-face

AB  - The problem of wastewater has long been ubiquitous and has great consequences for the environment and its inhabitants. Microbial fuel cells (MFCs) have enormous potential for the treatment of wastewaters polluted with azo dyes. The amount of energy that can be produced from a single-chamber MFC is sufficient to perform decolorization and degradation of such dyes, which are widely used in the textile industry. This study on the azo dye, reactive black 5 (RB5), provides an alternative method through three parallel-connected MFCs to obtain electricity that directly serves for the dye’s electrochemical degradation. We examined degradation followed by decolorization of RB5 using Fe and Pt electrodes, together with H2O2, to achieve the electro-Fenton process. The amount of voltage produced (295 mV), the current density (276 mA m−3) and the power density (50 mW m−3) were sufficient to degrade 25 mg L-1 RB5 dye with 0.5 mM H2O2 in just 2 h. The dye degradation mechanism was investigated using UV–VIS, FT-IR and HPLC-MS/MS. The ecotoxicity of the degradation products was assessed using a bacterial model, Aliivibrio fischeri. These tests showed that there was successful degradation of the dye to products whose toxicity is less than that of RB5.

AB  - This study aimed to determine the qualitative variability of essential oils of mountain germander – Teucrium
montanum L. (Lamiaceae) at the population level, depending on the type of geological substrate. Ten samples of
essential oils originated from aerial plant parts of populations from calcareous and ten from serpentinite were
tested by GCxGC-MS method. The obtained results showed that the serpentinite populations have more than 3
times higher essential oil yield than calcareous populations. Based on the average values for the relative percentage amounts of T. montanum essential oils, it was shown that the sesquiterpenes (34.89%) are the main
compounds in analyzed essential oils. Population from calcareous habitats synthesize twice as many aliphatic
hydrocarbons than populations from serpentinite habitats, while populations from serpentinite habitats synthesize twice as much mono- and sesquiterpenes. The compounds with highest relative percentage amounts in
calcareous populations was the hydrocarbon tetracosane (9.02%), while in serpentinite populations it was
oxygenated sesquiterpene, limonen-10-ol (4.81%). Compounds which were only detected for calcareous populations are: dodecane and isophytol, while for serpentinite populations are: 3-caren-2-ol, carvone oxide and
pyronene. The obtained results indicate a significant influence of the habitat geological substrate on the qualitative characteristics of the T. montanum essential oil. Differentiation of calcareous and serpentinite populations
into two distinct groups based on the essential oil composition indicate the significant presence of specific
chemotypes developed by the influence of various edaphic characteristics.

hydrocarbons than populations from serpentinite habitats, while populations from serpentinite habitats synthesize twice as much mono- and sesquiterpenes. The compounds with highest relative percentage amounts in
calcareous populations was the hydrocarbon tetracosane (9.02%), while in serpentinite populations it was
oxygenated sesquiterpene, limonen-10-ol (4.81%). Compounds which were only detected for calcareous populations are: dodecane and isophytol, while for serpentinite populations are: 3-caren-2-ol, carvone oxide and
pyronene. The obtained results indicate a significant influence of the habitat geological substrate on the qualitative characteristics of the T. montanum essential oil. Differentiation of calcareous and serpentinite populations
into two distinct groups based on the essential oil composition indicate the significant presence of specific
chemotypes developed by the influence of various edaphic characteristics.",

AB  - Exosomes are a sub-group of extracellular vesicles, playing an important part in a cell-cell communication in many physiological and pathological conditions. Their size and competence for transferring material to recipient cells make them a promising nanocarrier for clinical use. Their non-immunogenic nature, similar to the body's own structure make them far superior transporters compared to liposomes and polymeric nanoparticles. This review, will provide an overview of exosome biogenesis, biological role, and purification methods. The focus of this manuscript will be to summarize specific applications of exosomes and exosome-mimetics as drug delivery systems in pharmaceutical drug development. We will describe drug-loading approaches, in vivo and in vitro exosome tracing methods, specific modifications and examples of the delivery of therapeutic and imaging molecules from a variety of biological origins. Challenges in the translation of exosome-based drug carriers to clinical use will also be discussed in this review.

AB  - In the present work, we focused on two aspects of mercury (Hg) bioconcentration in the above-ground parts of Neoboletus luridiformis. In the first part, we monitored the bioconcentration potential of individual anatomical parts of a particular fruiting body and evaluated the obtained data by the spline interpolation method. In the second part, we focused on assessing the mercury content in 378 samples of N. luridiformis and associated samples of substrates from 38 localities with different levels of Hg content in Slovakia. From the obtained data of Hg content in samples of substrate and fungi, we evaluated ecological indicators (geoaccumulation index – Igeo, contamination factor – Cf a potential ecological risk – PER), bioconcentration indicators (bioconcentration factor – BCF; cap/stipe quotient – Qc/s) and health indicators (percentage of provisional tolerable weekly intake – %PTWI a target hazard quotient – THQ). Based on the Hg distribution results, the highest Hg content was found in the tubes & pores (3.86 mg/kg DW), followed by the flesh of cap (1.82 mg/kg DW). The lowest Hg content was in the stipe (1.23 mg/kg DW). The results of the BCF values indicate that the studied species can be included in the category of mercury accumulators. The results of the ecological indices representing the state of soil pollution pointed out that two localities (Malachov and Nižná Slaná) stood apart from all monitored localities and showed a state of an extremely disturbed environment. This fact was also reflected in the values of Hg content in the fruiting bodies of the studied mushroom species. In the case of the consumption of mushrooms from these localities, it can be stated that long-term and regular consumption could have a negative non-carcinogenic effect on the health of consumers. It was confirmed by the %PTWI (Malachov: 57.8%; Nižná Slaná: 53.2%) and THQ (Malachov: 1.11 Nižná Slaná: 1.02). The locality Čačín-Jelšovec is interesting from the bioconcentration characteristics point of view, where the level of environmental pollution was the lowest (Hg content in the soil was below the background value) compared to other localities, however, the THQ value was the highest (1.29).

AB  - A novel multiferroic composite material, composed of a mixture of nanocrystals of BaT1-xMexO3 and MeFe12O19 (Me = Zn and Mn) and an amorphous phases of BaTi1-xMexO3, MeFe12O19 and MeFe2O4, is synthetized. The composite material consisting of the mixture of nanocrystals of Fe2O3, ZnO and BaTiO3 embedded into the amorphous phase of MnCO3 is obtained by grinding the powder mixture of 17.0 wt% Fe2O3, 4.4 wt% MnCO3, 3.6 wt% ZnO and 75.0 wt% BaTiO3 for 20 min. The powders as-ground for 80 min and more are composed of the mixture of nanocrystals of Fe2O3 and BaTiO3 embedded in the amorphous phase of Fe2O3, ZnO, BaTiO3 and MnCO3. With increasing grinding time, formation of the composite with finer particles, a lower mean size of nanocrystals, higher content of the amorphous phase and higher magnetization is observed. The magnetization of the pressed samples increases with increasing grinding time. Grinding declines the amount of large weakly-ferromagnetic crystals of hematite, however it increases the quantity of paramagnetic small nanocrystals and the amorphous phase. The powder is thermostable up to 280 °C. Annealing above 280 °C results in the decrease in the magnetization of the cooled sample as a consequence of crystallization of the amorphous phase and enlargement of the size of nanocrystals. When sintering for 2 h at 1200 °C, the mixture of nanocrystals of BaTi1-xMexО3 and MeFe12O19 embedded into the amorphous matrix composed of BaTi1-xMexO3, MeFe12O19 and MeFe2О4 is formed. The sintered samples ground for longer periods of time are mainly composed of the amorphous phase and fine nanocrystals. Grinding of powders for less than 100 min results in the sintered samples with a granular structure, whereas the samples obtained from powders ground for more than 160 min are relatively compact. The magnetization of the sintered samples declines with increasing grinding time to 180 min due to transformation of nanocrystals into the amorphous phase. Further increase in grinding time from 180 to 240 min causes the increase in the magnetization, resulting from the effect of sintering. The magnetization of the sintered samples ground for more than 240 min declines with increasing grinding time, since the amount of the amorphous phase rapidly increases when grinding above 240 min. The samples sintered from the powders ground for 240 min show the compact structure and maximum magnetization.

AB  - Correct elucidation of physiological and pathological processes mediated by extracellular vesicles (EV) is highly dependent on the reliability of the method used for their purification. Currently available chemical/physical protocols for sample fractionation are time-consuming, often scarcely reproducible and their yields are low. Immuno-capture based approaches could represent an effective purification alternative to obtain homogeneous EV samples. An easy-to-operate chromatography system was set-up for the purification of intact EVs based on a single domain (VHH) antibodies-copolymer matrix suitable for biological samples as different as conditioned cell culture medium and human plasma. Methacrylate-based copolymer is a porous solid support, the chemical versatility of which enables its efficient functionalization with VHHs. The combined analyses of morphological features and biomarker (CD9, CD63 and CD81) presence indicated that the recovered EVs were exosomes. The lipoprotein markers APO-A1 and APO-B were both negative in tested samples. This is the first report demonstrating the successful application of spherical porous methacrylate-based copolymer coupled with VHHs for the exosome isolation from biological fluids. This inexpensive immunoaffinity method has the potential to be applied for the isolation of EVs belonging to different morphological and physiological classes.

Methacrylate-based copolymer is a porous solid support, the chemical versatility of which enables its efficient functionalization with VHHs. The combined analyses of morphological features and biomarker (CD9, CD63 and CD81) presence indicated that the recovered EVs were exosomes. The lipoprotein markers APO-A1 and APO-B were both negative in tested samples. This is the first report demonstrating the successful application of spherical porous methacrylate-based copolymer coupled with VHHs for the exosome isolation from biological fluids. This inexpensive immunoaffinity method has the potential to be applied for the isolation of EVs belonging to different morphological and physiological classes.",

AB  - In this paper, the previously synthesized Cu(II) complex ([CuL1(N3) (CH3OH)]BF4) with N,N,N-trimethyl-2-oxo-2-(2-(1-(thiazol-2-yl)ethylidene)hydrazinyl)ethan-1-aminium chloride, has been characterized and its biological activity has been studied in detail. The Cu(II) complex consists of ligand coordinated in a deprotonated, formally neutral zwitter-ionic form, via NNO atoms, one azido ligand and one methanol molecule. The Cu(II) complex was selected due to results of the cytotoxic activity, the brine shrimp test and DPPH radical scavenging activity, which were previously performed. The effects of Cu(II) complex on cell cycle phase distribution of cervical adenocarcinoma HeLa cells were investigated in order to examine the mechanisms of its anticancer activity. The measurement of intracellular ROS levels in HeLa and HaCaT cell lines were evaluated in order to explore their possible generation and the role in cytotoxic activity. The possible anti-invasive and anti-angiogenic properties of Cu(II) complex were evaluated. DNA binding experiments, including fluorescence displacement study and DNA cleavage experiments, were performed in order to obtain information on the type of DNA-metal complex interactions. © 2022 Serbian Chemical Society.

AB  - In this paper, Cu(II), Mn(II) and Zn(II) complexes with N,N,N-trimethyl-2-oxo-2-(2-(1-(thiazol-2-yl)ethylidene)hydrazinyl)ethan-1-aminium chloride (HL1Cl) were synthesized and characterized by single-crystal X-ray diffraction, IR spectroscopy, elemental analysis and DFT calculations. In all three complexes, a ligand (L1) is coordinated in a deprotonated formally neutral zwitterionic form via NNO donor set atoms. Cu(II) and Zn(II) form mononuclear penta-coordinated complexes [CuL1(N3)(CH3OH)]BF4 and [ZnL1(N3)2], respectively, while Mn(II) forms a binuclear [Mn2L12(μ-1,1-N3)2(N3)2]·2CH3OH complex, with unusual distorted trigonal-prismatic geometry around the metal centers. The antimicrobial activity of these complexes was tested against a panel of Gram-negative and Gram-positive bacteria, two yeasts and one fungal strain. The binuclear Mn(II) complex showed antifungal activity of similar intensity to amphotericin B. Based on the results of the brine shrimp test and DPPH radical scavenging activity, the most active Cu(II) and Mn(II) complexes were selected for evaluation of cytotoxic activity against five malignant cancer cell lines (HeLa, A375, MCF7, PC-3 and A549) and one normal cell line HaCaT. Both complexes showed significant activity. It should be pointed out that the activity of the Mn(II) complex against the MCF7 breast cancer cell line is only slightly weaker than that of cisplatin, but with selectivity to the tumor cell line in comparison to normal HaCaT cells, which is non-existent in the case of cisplatin.
