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  - Decarbonylation is an invaluable reaction, utilized by nature and chemists alike. In different life forms, such as prokaryotes, plants and animals, this transformation is catalyzed by aldehyde decarbonylases. In the laboratory, the transition metal-catalyzed (TMC) decarbonylation, which was first achieved in 1959, is by and large the dominant way for conducting this reaction. The carbon-carbon bond cleavage is most often made possible by RhCl(PPh3)3 i. e. Wilkinson's catalyst, but other metals are also used, both in academia and in industry. In this review, we chose to present the applications of TMC decarbonylation in the synthesis of natural products and their derivatives. More than 30 examples are showcased and categorized into three categories based on the essence of the role of the aldehyde group in the synthesis. A short outlook is given in the end, listing the different advantages and disadvantages of Wilkinson's catalyst, as well as offering a brief prospect for the future.

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  - Recently, we designed and synthesized a subnanomolar, reversible, dual-binding site acetylcholinesterase (AChE) inhibitor which consists of the tacrine and aroylacrylic acid phenylamide moieties, mutually linked by eight methylene units. To further investigate the process of the molecular recognition between the AChE and its inhibitor, we performed six unconstrained molecular dynamics (MD) simulations, where the compound in three possible protonation states was placed inside binding sites of two available AChE crystal structures. In all six MD trajectories, the ligand generally occupied similar space inside the AChE active site, but the pattern of the interactions between the ligand functional groups and the amino acid residues was significantly different and highly dependent upon the crystal structure used to generate initial systems for simulation.

AB  - Organic chemistry represents an essential part of everyday life, but previous research indicates
that traditional organic chemistry teaching, which focuses on the transmission of academic content, insufficiently promotes the development of pupils’ chemical literacy in this field. Since context-based teaching approach has the potential to improve scientific literacy, in order to compare the effectiveness of the aforementioned teaching approaches in terms of developing elementary school pupils’ chemical literacy in the field of organic chemistry, a pedagogical experiment with parallel groups was conducted. The experiment was organized within the elaboration of the teaching unit Alkanes and it encompassed 148 eighth-grade elementary school pupils (76 pupils in the experimental and 72 pupils in the control group). Through the elaboration of the content about alkanes, pupils develop chemical literacy in regard to the structure and nomenclature of these compounds, their physical and chemical properties and oil and its derivatives as energy sources, as well as environmental pollutants. Upon the elaboration of the abovementioned teaching unit, the experimental group achieved a significantly higher overall percentage of correct answers on the test that checked the development of pupils’ chemical literacy in regard to alkanes on all three levels (knowledge, application and reasoning), which implies that context-based teaching approach could significantly enhance elementary school pupils’ chemical literacy, in the field of organic chemistry.

AB  - The aim of this study was to compare total phenolic content (TPC), radical-scavenging activity (RSA), total anthocyanin content (TAC), sugar and polyphenolic profiles of two apple cultivars (‘Discovery’ and ‘Red Aroma Orelind’) from organic and integrated production systems in climatic conditions of Western Norway. Sixteen sugars and four sugar alcohols and 19 polyphenols were found in the peel, but less polyphenols were detected in the pulp. The peel of both apples and in both production systems had significantly higher TPC and RSA than the pulp. The peel from integrated apples had higher TPC than the peel from organic apples, while organic apples had higher TAC than the integrated. Sucrose and glucose levels were higher in organic apples; fructose was cultivar dependent while minor sugars were higher in integrated fruits. The most abundant polyphenolic compound in the peel of the tested cultivars was quercetin 3-O-galactoside, while chlorogenic acid was most abundant in the pulp. Regarding polyphenols, phloretin, phloridzin, protocatechuic acid, baicalein and naringenin were higher in organic apple, while quercetin 3-O-galactoside, kaempferol 3-O-glucoside, chlorogenic acid and syringic acid was higher in integrated fruits. In conclusion, organic ‘Discovery’ and integrated ‘Red Aroma Orelind’ had higher bioavailability of health related compounds from the peel and the pulp.

AB  - Three Re(V) complexes of structural formulas [ReOCl2L(PPh3)], where L is pyridine-2-carboxylic acid (C1), 3-
methyl-pyridine-2-carboxylic acid (C2) and 6-methyl-pyridine-2-carboxylic acid (C3) were synthesized and
characterized using NMR, IR spectroscopy and mass spectrometry. Crystal structures of all three complexes have
been additionally confirmed by X-ray analysis. The biological activity has been investigated in the panel of tumor
cell lines A549, PANC-1, MDA-MB-231, MCF-7, LS-174, EAhy.926 and one in non-tumor cell line MRC-5. Only
C1 showed dose-dependent cytotoxic potential, particularly toward triple-negative breast adenocarcinoma cells
MDA-MB-231 with IC50 68.90 ± 1.73 μM and pancreatic adenocarcinoma cells PANC-1 with IC50 69.84 ± 2.3
μM. Both cell lines are characterized by a highly invasive and resistant phenotype. Drug combination studies in
PANC-1 cells with C1 and Verapamil hydrochloride (VRP), which is the established inhibitor of efflux transporter
P-glycoprotein (Pgp), revealed enhancement of antiproliferative action of the complex in a dose-dependent
manner, 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 the
IC50 57.67 ± 6.51 (μM). A morphological analysis in PANC-1 cells by dual acridine orange/ethidium bromide
staining, revealed apoptotic potential of complex C1 and a slower kinetic of cell death induction, suggesting a
different mechanism of action compared to cisplatin.

Crystal structures of all three complexes havebeen additionally confirmed by X-ray analysis. The biological activity has been investigated in the panel of tumorcell lines A549, PANC-1, MDA-MB-231, MCF-7, LS-174, EAhy.926 and one in non-tumor cell line MRC-5. OnlyC1 showed dose-dependent cytotoxic potential, particularly toward triple-negative breast adenocarcinoma cellsMDA-MB-231 with IC50 68.90 ± 1.73 μM and pancreatic adenocarcinoma cells PANC-1 with IC50 69.84 ± 2.3μM. 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.

AB  - The hydrogen bonds of noncoordinated (NH/O) and coordinated ammonia (MLNH/O) with water molecules were studied by analyzing data in the Cambridge Structural Database (CSD) and by DFT calculations. The data from the CSD on the distribution of hydrogen bond dHO distances of the coordinated ammonia show a peak in the range of 2.0–2.2 Å with a significant number of hydrogen bonds in the range of 1.8–2.0 Å. Analysis of Hirshfeld surfaces showed that coordinated NH3 molecules are involved in numerous noncovalent contacts. The DFT calculations were performed on linear complexes of silver(I), square-planar complexes of platinum(II), tetrahedral complexes of zinc(II), and octahedral complexes of cobalt(III) by varying the charge of the complexes. The calculated data show that coordinated ammonia has stronger hydrogen bonds than noncoordinated ammonia, even for neutral complexes. The hydrogen bond energy of noncoordinated ammonia is −2.3 kcal/mol, while for coordinated ammonia, attractive interactions are in the range of −3.7 to −25.0 kcal/mol, depending on the metal ion and charge of the complex. The interaction energies for metal complexes from neutral to charged species are for the linear silver(I) complex from −6.0 to −10.7 kcal/mol, while for the square planar complex, interactions span from −5.9 to −19.9 kcal/mol. The tetrahedral zinc(II) complexes have interaction energy from −5.5 to −17.5 kcal/mol, while for the octahedral cobalt(III) complex, attractive interaction energies are from −3.7 to −25.0 kcal/mol. With the increasing charge of the metal complex, the hydrogen bond between coordinated ammonia and free water becomes stronger, and in accordance with that, the dHO distance becomes shorter. The bifurcated interaction is stronger than monofurcated for all complexes. The interaction energies correspond well with the electrostatic potential (Vs) values on interacting hydrogen atoms; the more positive Vs values on hydrogen atoms lead to stronger interaction. The hydrogen bond between ammonia and water molecules (−2.3 kcal/mol) is quite weak in comparison to the water/water hydrogen bond; it is 50% of the water/water hydrogen bond (−4.84 kcal/mol). Although the hydrogen bonds of coordinated ammonia are also weaker than hydrogen bonds of coordinated water molecules, the difference is smaller, indicating the importance of the coordination on the strength of hydrogen bonds.

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  - 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  - Novel macroporous copolymers of glycidyl methacrylate and ethylene glycol dimethacrylate with mean pore size diameters ranging from 150 to 310 nm were synthesized by dispersion polymerization and modified with ethylenediamine. The glutaraldehyde and periodate method were employed to immobilize horseradish peroxidase (HRP) onto these carriers. The activity of the immobilized enzyme was greatly affected by the pore size of the carrier. The highest specific activities of 9.65 and 8.94 U/g of dry weight were obtained for HRP immobilized by the periodate-route onto poly(GMA‐co‐EGDMA) carriers with pore size diameters of 234 and 297 nm, respectively. Stability studies showed an improved operational stability of immobilized peroxidase at 65 °C and in an organic solvent. HRP immobilized on a copolymer with a pore size of 234 nm, showing the highest specific activity and good stability, had higher activities at almost all pH values than the native enzyme and the increased Km value for pyrogallol oxidation. Immobilized HRP retained 80% of its original activity after five consecutive cycles of the pyrogallol oxidation and 98% of its initial activity in a storage stability study. Enzyme immobilized onto the macroporous copolymer with the pore size diameter of 234 nm showed a substantial degree of phenol removal achieved by immobilized peroxidase.

Enzyme immobilized onto the macroporous copolymer with the pore size diameter of 234 nm showed a substantial degree of phenol removal achieved by immobilized peroxidase.",

AB  - Progressive industrialization in recent decades has contributed to the increase of metal levels in the environment, which has a dangerous impact on human health, primarily pregnant women. In this study, we aimed to compare levels of various elements in maternal and umbilical cord (UC) plasma samples collected from 125 healthy pregnant women, conduct correlation analysis among paired plasma samples, and compare our data with other populations worldwide. The study design included the following elements: essential (Mn, Co, Cu, Zn, Se, Mo), non-essential (Be, Al, Ni, As, Rb, Sr, Cd, Sb, Pb, U), rare earth (La, Pr, Ce, Nd, Sm, Eu, Gd, Dy, Ho, Er), and noble metals (Ru, Rh, Re, Pt). Levels of 30 elements were higher in maternal plasma than in UC plasma samples. However, no disparities at the statistically significant level were found for Be, Zn, Rb, Cd, Ce, and Ho. Correlation analysis among paired plasma samples revealed only positive/synergistic correlations of different strengths between most elements. Compared to other countries across the globe, our participants had considerably lower plasma levels of Zn and higher levels of Co, Ni, and As. This study provides not only a new and deeper comprehension, but also the first insight into the levels, correlation, distribution, and potential transplacental transfer of 30 elements.

AB  - The aim of this study was to investigate a possibility of synthesis of porous ceramics with controlled open porosity, which could be used as sorbents and catalyst supports. Two organic additives were used to obtain open porosity: polystyrene beads and cellulose fibers, which are mixed with kaolin clay powder and the appropriate water content. Samples were sintered at 1050 oC for 1 h. Characterization of the obtained products included X-ray powder diffraction analysis (XRPD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and elemental CHNS analysis. In addition, porosity was examined by quantification of visual information. The specific surface areas were determined by the Brunauer–Emmett–Teller (BET) method. Also, density and compressive strength of the obtained samples were assessed. It was determined that by sintering, the organic component completely leaves the system. For samples prepared with polystyrene beads and with cellulose fibers, satisfactory mechanical properties were obtained: compressive strengths were 1.42 and 1.56 MPa, respectively. It was noted that significantly higher open porosity was obtained by using polystyrene beads as a sacrificial template (porosity of ~56 %) instead of cellulose fibers (porosity of ~6 %).

AB  - A detailed investigation of significance of the infrared (IR) spectro­scopic branching factor (СН2/СН3; the ratio of methylene and methyl group peak heights at 2917–2921 and 2951–2954 cm-1, respectively in the IR spectra) for charac­te­ri­za­tion of alkane structure, geochemical properties and viscosity of 76 oil samples was performed. These oils, originating from 13 Serbian oil fields in SE Pannonian Basin, differ according to source and depositional envi­ronment of organic matter (OM), as well as by thermal maturity and biodeg­rad­ation stage. Methylene and methyl asymmetric stretching peak absorbances were used for the branching factor calculation. CH2 peak positions exhibited3–4 cm-1 red shift with increasing the CH2/CH3 ratio, due to a greater contri­bution of trans vs. gauche rotamers in ali­pha­tic chains. Comparing IR spectra of the oils and model n-alkanes, it was established that the average (CH2)n methylene chain length per СН3 group varied from n = 3.5 to 6.5. The CH2/CH3 ratio showed significant concordance with geochemical para­meters, enabling clear distinction of the oils according to source and deposi­ti­onal environment of OM. At the same time, dependence of the CH2/CH3 ratio on oil maturity in the range from immature to mature was not observed, allowing for an accurate determination of oil genetic types irrespective of maturity. The CH2/CH3 ratio showed good accordance with oil biodegradation scale and oil viscosity.

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.

AB  - In order to explain the development of understanding of chemical concepts at the
macroscopic, submicroscopic and symbolic level over time, models of the expanding
triangle and rising iceberg are proposed. In order to validate the two models, this
study examined whether the depth of understanding of the concepts physical and
chemical changes at each of the levels significantly changes with the age of students,
whether selected age groups exhibit significant differences in understanding at the
three levels, and whether findings for these age groups differ. Therefore, 121 14-yearold, 108 16-year-old and 112 19-year-old students completed the test that checked
their understanding of the aforementioned concepts, at all three levels. The 16-
and 19-year-old students significantly outperformed the 14-year-old students at
each of the levels, while all age groups showed significantly better understanding
of physical and chemical changes at the macroscopic and symbolic, in comparison
to the submicroscopic level. It was concluded that, while the proposed models are
generally valid, the applied teaching approaches and the composition of the chemistry
curriculum have a profound impact on the development of students’ conceptual
understanding, at all three levels of chemistry knowledge.

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  - 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.
