AB  - We present the green, highly atom-economical, solid-state silica gel-catalyzed synthesis of polysubstituted 1,4- and 1,2-dihydropyridines (DHPs) from commercially available materials, amines and ethyl propiolate. The DHP skeleton was assembled by heating the reactants and silica gel in a closed vessel. Aliphatic amines provided 1,4-isomers as the main or only DHP products, but the reactions of aromatic amines yielded a mixture of 1,4- and 1,2-isomers. To the best of our knowledge, this is the first example of the formation of a 1,2-DHP structure by the reaction of an amine with propiolic ester. Addition of 1 mass percent of H2SO4 to silica gel shifted the product distribution to 1,4-DHP as the main or the only isomer obtained. Experimental and theoretical analyses led to the identification of two key intermediates en route to DHPs and the explanation of the observed regioisomeric ratios. 1,2-DHPs show blue-cyan fluorescence in MeOH with the quantum yield Φ = 0.10–0.22 relative to quinine sulfate Φ = 0.58 and 1,4-DHPs show blue-violet fluorescence with Φ = 0.09–0.81.

AB  - Herein, a screen–printed diamond electrode (SPDE) coupled with a “point-of-care” platform (30 µL-drop concepts, single-drop-detection approach) was successfully applied for the electrochemical determination of pterostilbene (PTS). Cyclic voltammetry identified irreversible oxidation of PTS, where oxidation peak was shown to be strongly dependent on the pH of the working environmental. Although the proposition of the detailed electrochemical oxidation mechanism of PTS goes out of the scope of the present research, we have determined the most probable reactive site of our analyte, by utilizing DFT-based reactivity descriptors (Fukui functions). For electrochemical quantification of PTS, oxidation peak at 0.32 V (vs. Ag/AgCl) was followed in presence of 0.5 mol L−1 of Briton–Robinson buffer solution (pH = 9). Coupled with the optimized parameters of differential pulse voltammetry (DPV), SPDE detected PTS in two linear ranges (first range was from 0.011 to 0.912 µmol L−1; second range was from 0.912 to 4.420 µmol L−1), providing the LOD and LOQ on a nanomolar level (3.1 nmol L−1 and 10.0 nmol L−1, respectively). The selectivity of the optimized DPV method was found to be excellent, with the current changes of less than 7%, in the presence of ten times higher concentrations of the certain interferences. The practical applicability of the SPDE and single-drop-detection approach in dietary supplements (with a declared PTS content of 50 mg/tablet), with the recovery values ranging from 95 to 102%, shows that the developed method has high potential for precise and accurate PTS detection, as well as exceptional miniaturization possibilities of relevant equipment for on-site sensing.

AB  - Serotonin receptors modulate numerous behavioral and neuropsychological processes. Therefore, they are the target for the action of many drugs, such as antipsychotics, antidepressants, antiemetics, migraine remedies, and many others. The 5-HT1A receptors have been involved in the pathogenesis and treatment of anxiety and depression and represent a promising target for new drugs with reduced extrapyramidal side effects. In most antidepressants, a piperazine-based structural motif can be identified as a common moiety. Here we describe the synthesis, pharmacological, and in silico characterization of a novel arylpiperazines series with excellent 5-HT1A affinity. The final compounds, 4a, 8a, and 8b, were selected according to predictions of in silico pharmacokinetics, docking analysis, and molecular dynamics in conjunction with physical properties, and metabolic stability. The accentuated molecules could serve as a lead compound for developing 5-HT1A drug-like molecules for depression treatment.

AB  - Methods for drug solubilization have become important part of modern drug discovery and 
development due to increasing number of extremely insoluble drugs and drug candidates. 
One of such methods is acid-base supersolubilization (ABS) [1]. Clofazimine (CFZ) is weakly 
basic antibiotic and anti-inflammatory drug, most notably used in the treatment of leprosy
and tuberculosis, with recently proven inhibitory activity against several coronaviruses [2].
We have recently unraveled its aqueous pKa value and its unique cosolvent dependence [3]. 
The aim of the present study was to investigate CFZ solubilization using the ABS approach. 
Eight small organic acids were tested for the ABS effect (glutaric, malic, tartaric, citric, 
malonic, maleic, succinic, adipic) but only glutaric (GA), malic (MA), and tartaric (TA) acids 
showed some solubilization effect. The effect of their concentration (and the solution pH 
value) was further tested. The solubility of CFZ was determined in GA, MA, and TA solutions 
in wide concentration (1.0×10-2 – 5.0 M) and pH range (~0.2 – 4.8). Equilibration time was 
24 hours (6 h of stirring + 18 h of sedimentation). Phases were separated by filtration. The 
CFZ concentration in supernatant was determined by HPLC-UV/VIS. Results show that CFZ 
solubility increases as acid concentration increases: from 3.04×10-3 to 10.68 mg/mL (in GA), 
from 9.06×10-3 to 1.23 mg/mL (in MA) and from 4.76×10-3 to 0.32 mg/mL (in TA). The effect 
of CFZ solubilization is much more pronounced when the acid concentration is raised above 
2 M. These results can be used as the basis for further CFZ formulation optimization.
Furthermore, our ongoing research is focused on the type of interactions and other possible 
factors that can influence CFZ and other prectically insoluble drugs, embracing (super)solu bilization as a general methodology in drug design and development.

AB  - The combination ofb-oligosaccharides from enzymatically hydrolysed barleyb-glucan has attracted inter-est recently due to its positive effects on human health. This study aimed to assess the impact of theendo-b-1,3-1,4-glucanase enzyme fromBacillus  subtilis168 on improving the nutritional and bioactiveproperties of barleyb-glucan.

AB  - Since the introduction of combinatorial chemistry and high-throughput screening in drug 
discovery in the early 1990s, the solubility of new chemical entities (NCE) decreased drastically 
while their lipophilicities increased greatly. Characterizing physicochemical properties of low soluble molecules can be especially challenging, since such molecules can undergo 
complicated reactions in aqueous solution, such as forming precipitates or complexes with 
buffer species or undergoing self-aggregation (dimer, trimer, etc.)1,2 or micelle formations. 
Most drugs are ionizable. Foremost to the rational interpretation of solution behavior of 
ionizable drugs in a physiologically-relevant pH domain requires an accurate aqueous pKa, 
determined by a suitable method. In a pH-dependent measurement of a property (e.g. 
solubility-, lipophilicity-, permeability-pH), when the apparent pKa value is different from the 
true aqueous pKa value, it may be an early clue that nonideal solution behavior may be taking 
place. In pharmaceutical research, it may seem cost-effective to use calculated pKa instead of 
measured values, but paradoxically, such preference can lead to inaccurate rationalization of 
the pH-dependent behavior of the drug molecule. For simple molecules, calculated values can 
be useful, but for today’s new drugs or for molecules prone to complicated solution behavior, 
the use of calculated pKas can substantially wrench the interpretation of solution properties. 
Clofazimine (CFZ), although discovered about 66 years ago, and used therapeutically for nearly 
40 years, exhibits some of the properties of relatively recent drug molecules by being 
extremely water insoluble and having variable pKa values reported. We have recently 
combined potentiometric titrations and UV/Vis spectrophotometry in methanol-water 
cosolvent media, accompanied by DFT calculations, to assess the hypothesis of CFZ free base 
dimerization. We reasoned that a soluble dimer might form from drug-drug adhesion along 
the hydrophobic molecular surface. With lessened exposure of the hydrophobic surface to 
water, the dimer would be more water soluble than the monomeric free base. In saturated 
solutions, the apparent solubility in alkaline pH would be elevated due to the presence of the 
dimer. The effect of that would be a lower pKa and reverse pKa cosolvent dependence – the 
behaviour we have noticed in CFZ aqueous solutions. These findings are of paramount 
importance for understanding of CFZ speciation and the future progress in developing its 
improved formulations which is the subject of our ongoing studies.

AB  - У индустријској зони града Ковина налазe се фабрике које се баве производњом алкохола и сточног квасца, хране за кућне љубимце, сечењем и завршном обрадом челика, производњом шприцева и амбалаже за вакцине и лекове, као и највећа на Балкану фарма печурака. Поред тога, на 11 km од Ковина је рудник који угаљ вади са дна језера које је повезано са Дунавом, и представља јединствену подводну експлоатацију угља на свету. Упркос наведеним бројним делатностима које могу имати утицаја на квалитет површинских вода, нема лабораторије која се бави њиховим мониторингом. Стога је циљ овог рада прелиминарна карактеризација степена оптерећења површинских вода укупно присутним и специфичним, најзаступљенијим угљоводоничним загађујућим супстанцама. Узорци коришћени у раду узети су током новембра 2022. године, са пет репрезентативних локација на подручју Ковина (слика 1). Након одређивања основних параметара (табела 1), воде су анализиране применом стандардне методе ASTM D1252-06 [1], како би се утврдиле вредности хемијске потрошње кисеоника (ХПК). У циљу специфицирања најзаступљенијих угљоводоничних загађујућих супстанци, примењена је екстракција узорака вода помоћу трихлорметана. Добијени екстракти су након сушења и концентровања хроматографски пречишћени и анализирани на гасном хроматографу Agilent 7890A GC куплованом са квадруполним масеним детектором Agilent 5975C. Четири од пет анализираних узорака показују вредности ХПК карактеристичне за класу III површинских вода (табела 1; [2]). Најзаступљeнија специфична угљоводонична једињења у свим узорцима су n-алкани (слика 1). Нижи n-алкани са мање од 20 угљеникових атома су присутни само у траговима, што указује да ове воде углавном нису изложене загађењу сировом нафтом, дизелом или керозином. У три узорка (Дунавац, Шљункара и Црна Бара), CPI вредности за цео опсег n-алкана (С16- С34), као и за и више (С25-С34) и ниже (С15-С20, са изузетком Шљункаре) n-алканске хомологе су ниже или блиске 1, што уз n-алканске максимуме у опсегу С24-С26 указује на допринос органске супстанце акватичних макрофита, бактерија, васкуларних биљака и маховина рода Sphagnum [3]. Присуство нижих n-алкана (С15-С20) карактерише алге и бактерије, док се доминација непарних нижих хомолога у узорку Шљункара може повезати за цијанобактеријама. У узорицима Канал и Поњавица CPI вредности за цео опсег n-алкана (С16-С34), као и за више хомологе (С25-С34) веће су од 1, што уз n-алкански максимум у узорку Канал на С27 указује на допринос виших сувоземних биљака. Међутим поред наведених природних извора идентификованих n-алкана, треба истаћи да веома сличне n-алканске расподеле имају моторна уља, теже фракције уља за ложење и течни производи пиролизе лигнита. Од посебног значаја је и резултат да је у екстракту узорка воде са локације Поњавица доминантно једињење елементарни сумпор (слика 1), што се може повезати са великом количином муља у којем преовлађују аноксични услови, услед чега су фаворизовани редукциони хемијски/биохемијски процеси. Резултати прелиминарног истраживања показују да је неопходно наставити континуално и знатно детаљније истраживање предметних вода, како би се предупредило њихово даље загађење и негативан утицај на живи свет у њима, као и на подземне воде и земљиште у непосредној околини.

AB  - The aggregation of proteins into fibrillar, amyloid-like aggregates generally results in an improved, positive effect on various techno-functional properties within food products, such as gelation, emulsification, and foam stabilization. These highly stable structures, characterized by their repetitive, β-sheet rich motifs, may develop as the result of the thermal treatment of protein-rich food products. Heavy metal ions can influence amyloid-like aggregation of food proteins. Lead(II) and cadmium(II) represent some of the most abundant and common environmental water and food pollutants. In this work, the influence of heavy metal ions, lead and cadmium on amyloid-like aggregation of ovalbumin at high temperatures (90 °C) and under acidic conditions (pH 2.0) was investigated. Ovalbumin is used as a general model for how heavy metals can affect amyloid-like aggregation of a food protein. Structural changes were monitored via Thioflavin T and 8-Anilino-1-naphthalenesulfonic acid fluorescence, Fourier-Transform infrared spectroscopy, atomic force microscopy, dynamic light scattering, as well as computational analyses. The obtained results indicate that the added heavy metal ions bind to different sites within ovalbumin prior to thermal treatment. Lead binding sites are closer to the hydrophobic regions of an protein, while cadmium ion binding sites are more exposed. This specific binding of metal ions affects the morphologies of amyloid-like aggregates, resulting in lead-induced branching of amyloid-like fibrils, or cadmium-induced tangling of fibrils into dense amyloid clusters. This additive effect of heavy metal ions is most evident in ovalbumin samples which contain a mixture of both heavy metal ions.

AB  - Interest in Cd complexes has been growing in recent years. Cd complexes are considered a potential solution in the search for novel antibiotics that can fight antimicrobial resistance. In addition, Cd complexes draw attention to material chemistry. The main objective of this work was to prepare the first Cd(II) complexes with anionic forms of pyridine-based thiazolyl hydrazone (THs) ligands HLS2 [(E)-4-(4-methoxyphenyl)-2-(2-[pyridine-2-ylmethylene]hydrazinyl)thiazole] and HLS3 [(E)-2-(2-[pyridine-2-ylmethylene]hydrazinyl)-4-(p-tolyl)thiazole] and perform their structural and spectroscopic characterization, as well as stability in solution and upon heating. Studies related to their biological activities and possible electrochromic applications are also being conducted. Complexes [Cd(HLS2)2] (1) and [Cd(HLS3)2] (2) have been characterized by a single-crystal X-ray diffraction and computational analysis of intermolecular interactions responsible for their solid-state structures was performed. Thermal stability of 1 and 2 in the solid-state was analyzed by TGA/MS, where as their solution stability was determined by the spectrophotometric titration method. Electrochemical and in situ UV–Vis spectroelectrochemical analyses of 1 and 2 were carried out to determine redox mechanisms and the influence of the substituents and electrolytes on their redox responses. The antioxidant capacity of both complexes was tested in antioxidant assays, while their antimicrobial activity was tested against five Gram-positive and four Gram-negative bacteria, as well as against three fungi. The obtained results indicate their potent antioxidant capacity. The antimicrobial activity of investigated compounds on almost all tested bacterial strains was stronger than that of the standard antibiotic erythromycin. The results of docking studies indicate that the minor groove DNA is the possible biological target of 1 and 2.

AB  - Fourteen novel quinoline-4-carboxylic acid-chalcone hybrids were obtained via Claisen–Schmidt condensation and evaluated as potential human dihydroorotate dehydrogenase (hDHODH) inhibitors. The ketone precursor 2 was synthesized by the Pfitzinger reaction and used for further derivatization at position 3 of the quinoline ring for the first time. Six compounds showed better hDHODH inhibitory activity than the reference drug leflunomide, with IC50 values ranging from 0.12 to 0.58 μM. The bioactive conformations of the compounds within hDHODH were resolved by means of molecular docking, revealing their tendency to occupy the narrow tunnel of hDHODH within the N-terminus and to prevent ubiquinone as the second cofactor from easily approaching the flavin mononucleotide as a cofactor for the redox reaction within the redox site. The results of the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay revealed that 4d and 4h demonstrated the highest cytotoxic activity against the A375 cell line, with IC50 values of 5.0 and 6.8 µM, respectively. The lipophilicity of the synthesized hybrids was obtained experimentally and expressed as logD7.4 values at physiologicalpH while the solubility assay was conducted to define physicochemical characteristics influencing the ADMET properties.

AB  - The Zn(II) complexes [Zn(HLSe2)2](NO3)2∙CH3OH (2-NO3-Se) and [Zn(HLSe3)2](NO3)2·DMF (3-NO3-Se) with selenazolyl-hydrazone ligands 4-(4-methoxyphenyl)-2-(2-(pyridin-2-ylmethylene)hydrazinyl)-1,3-selenazole (HLSe2) and 4-(4-methylphenyl)-2-(2-(pyridin-2-ylmethylene)hydrazinyl)-1,3-selenazole (HLSe3) have been synthesized and characterized using singe crystal X-ray diffraction analysis. Antiproliferative activities of 2-NO3-Se and 3-NO3-Se, the corresponding ligands and sulphur isosteres of the complexes and the ligands were determined on non-malignant HTR-8/SVneo extravillous trophoblast cell line and malignant JEG-3 and JAr choriocarcinoma cell lines. All Zn complexes exhibited cytotoxic effect, comparable to that of a reference metal-based drug, cisplatin. The antioxidant activity of all compounds was determined in three antioxidant assays: ORAC (Oxygen Radical Absorbance Capacity), ABTS [(2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt] and CERAC [Ce(IV)-based reducing capacity]. As a result of synergy between Zn(II) and selenazolyl-hydrazone ligands, the complexes 2-NO3-Se and 3-NO3-Se appeared to be more active than Trolox, which is not the case for their sulfur counterparts. In-silico calculations of ADME properties pointed that the compounds possess some of desirable Lipinski rule principles. Applied algorithms did not report the compounds as potential PAINS or covalent inhibitors, although due to high molecular weight none of the compounds represent a potential lead compound. Toxicity prediction of the compounds is performed using machine learning models. The complexation of the ligands most likely reduces their toxicity or reduces their negative metabolic effects.

AB  - Besides being one of the most commercially grown berry fruits, strawberries (Fragaria x annanassa Duch.) are known for their nutritional value, richness in polyphenols, and antioxidant capacity. New directions of strawberry breeding and selection are set towards premium fruit quality, high sugars content, and desirable sugars/total acids ratio (sweet index, SI), which represent some of the main prerequisites for selecting new breeding materials [1]. With this intention, a set of 24 strawberry genotypes was cultivated, including 12 parental varieties and 12 of their descendants - perspective candidates obtained by crossing the parental varieties mentioned above. A total of eleven sugars were quantified using High-Performance Anion-Exchange Chromatography with Pulsed Amperometric Detection (HPAEC-PAD). Results implied that glucose, sorbitol, sucrose, and melibiose content were the most important sugars in separating the fruits of parental varieties and their progeny [2]. Results showed that old, parental varieties had a significantly higher content of glucose and sucrose, while new perspective genotypes had higher sorbitol and melibiose content (Fig.2). PCA analysis confirmed that parental (samples 1-12) and descendant genotypes (samples 13-24), could be discriminated according to sugars profile i.e. that these four sugars have an effect on their differentiation (Fig.1). This was in accordance with Mann-Whitney U test results (Fig.2).Fig.1.

AB  - Interest in production of protected crops has grown significantly over the past decade. Different cultivation systems (conventional, integral, and organic) affect the biological activity, which is ultimately reflected in the high quality of the fruits of different vegetable crops. In accordance with the requirements for health-safe products without residues of harmful substances in fruits, there is an increasing need for the production of tomatoes in integral and organic production systems. One of the most important features of these vegetables is their high quality and health safety, high nutritional and biological value. Agricultural production systems and growing practices are critical factors in determining the nutritional quality of tomato fruits [1]. In tomato, the sugar content is one of the important factors and one of the most significant parameters from the aspect of food quality [1]. Therefore, the aim of this work is to monitor fluctuations in sugars content, as parameters
that determine the nutritional value in tomato cultivars, induced by growing under integral and organic conditions. For this purpose, a set of sixteen samples of four types of tomatoes - beef, grapolo, mini and midi plum, and cherry - was analyzed. Each type of tomato included two varieties, grown in two agricultural systems - integral and organic. The sugars profile was obtained using High-Performance Anion Exchange Chromatography with Pulsed Amperometric Detection (HPAECPAD). The content of eleven sugar components was determined. Fructose and glucose were the major sugar compounds [2], while the sugar microcomponents were trehalose, arabinose, melibiose, sucrose, isomaltose, gentiobiose, raffinose, maltose, and panose. The results showed differences between samples produced in integral and organic growing systems, primarily in microsugar components. Higher content of trehalose and melibiose was found in samples obtained from organic production.

Fig.1.

abstract = "Interest in production of protected crops has grown significantly over the past decade. Different cultivation systems (conventional, integral, and organic) affect the biological activity, which is ultimately reflected in the high quality of the fruits of different vegetable crops. In accordance with the requirements for health-safe products without residues of harmful substances in fruits, there is an increasing need for the production of tomatoes in integral and organic production systems. One of the most important features of these vegetables is their high quality and health safety, high nutritional and biological value. Agricultural production systems and growing practices are critical factors in determining the nutritional quality of tomato fruits [1]. In tomato, the sugar content is one of the important factors and one of the most significant parameters from the aspect of food quality [1]. Therefore, the aim of this work is to monitor fluctuations in sugars content, as parameters
that determine the nutritional value in tomato cultivars, induced by growing under integral and organic conditions. For this purpose, a set of sixteen samples of four types of tomatoes - beef, grapolo, mini and midi plum, and cherry - was analyzed. Each type of tomato included two varieties, grown in two agricultural systems - integral and organic. The sugars profile was obtained using High-Performance Anion Exchange Chromatography with Pulsed Amperometric Detection (HPAECPAD). The content of eleven sugar components was determined. Fructose and glucose were the major sugar compounds [2], while the sugar microcomponents were trehalose, arabinose, melibiose, sucrose, isomaltose, gentiobiose, raffinose, maltose, and panose. The results showed differences between samples produced in integral and organic growing systems, primarily in microsugar components. Higher content of trehalose and melibiose was found in samples obtained from organic production.

AB  - Besides being one of the most commercially grown berry fruits, strawberries (Fragaria x annanassa Duch.) are known for their nutritional value, richness in polyphenols, and antioxidant capacity. New directions of strawberry breeding and selection are set towards premium fruit quality, high sugars content, and desirable sugars/total acids ratio (sweet index, SI), which represent some of the main prerequisites for selecting new breeding materials [1]. With this intention, a set of 24 strawberry genotypes was cultivated, including 12 parental varieties and 12 of their descendants - perspective candidates obtained by crossing the parental varieties mentioned above. A total of eleven sugars were quantified using High-Performance Anion-Exchange Chromatography with Pulsed Amperometric Detection (HPAEC-PAD). Results implied that glucose, sorbitol, sucrose, and melibiose content were the most important sugars in separating the fruits of parental varieties and their progeny [2]. Results showed that old, parental varieties had a significantly higher content of glucose and sucrose, while new perspective genotypes had higher sorbitol and melibiose content (Fig.2). PCA analysis confirmed that parental (samples 1-12) and descendant genotypes (samples 13-24), could be discriminated according to sugars profile i.e. that these four sugars have an effect on their differentiation (Fig.1). This was in accordance with Mann-Whitney U test results (Fig.2).

AB  - Considering the health-benefits of berry fruits consumption and increased market demands for food authenticity
as one of the most important quality assurances, phenolic profiling by high-performance thin layer chroma-
tography and ultra-high-performance liquid chromatography hyphenated with mass spectrometry was combined
with multivariate analysis for phytochemical characterization and intercultivar discrimination of cultivated
berry seeds. The phenolic profiles of 45 berry seeds from nine genuine Serbian cultivated fruit species (straw-
berry, raspberry, blackberry, black currant, blueberry, gooseberry, cape gooseberry, chokeberry, and goji berry)
revealed a good differentiation according to botanical origin. In order to determine biomarkers responsible for
the classification, a total of 103 phenolic compounds were identified, including 53 phenolic acids and their
derivatives, 26 flavonoids and 24 glycosides. Biomarkers derived from the phenolic profile of berry seeds proved
to be a powerful tool in the authentication of botanical origin, and may be useful in detection of frauds in berry-
based seed-containing product.

AB  - The aim of this study is to develop a rapid, effect-directed screening method for quality assessment of bee pollen-honey mixtures. The comparative antioxidant potential and phenolic content of honey, bee pollen, and the bee pollen-honey mixtures, was performed using spectrophotometry. The total phenolic content and antioxidative activity of bee pollen-honey mixtures with 20 % bee pollen share were in the range 3.03–3.11 mg GAE/g, and 6.02–6.96 mmol TE/kg, respectively, while mixtures with 30 % bee pollen share contained 3.92–4.18 mg GAE/g, and 9.69–10.11 mmol TE/kg. Chromatographic fingerprint of bee pollen-honey mixtures was performed by high-performance thin-layer chromatography with conditions developed by authors and reported for the first time. Fingerprint analysis hyphenated with chemometrics enabled authenticity assessments of honey in mixtures. Results indicate that bee pollen-honey mixtures represent a food with highly, both, nutritious characteristics and health-promoting effect.

AB  - Propolis is a resinous natural substance collected by honeybees from different plant sources. The element content of propolis is influenced by the content of elements in the soil, climatic factors, and the degree of pollution. The aim of the study was to characterize element composition and content of toxic elements in 51 propolis collected from different locations in Serbia and to evaluate the differences among them. Determination of the 21 elements were performed using Inductively coupled plasma - optical emission spectrometry. K was the most abundant element, followed by Ca, Mg, Si, Fe, Zn, and Al. The microelements B, Ba, Mn, Na, Pb, and Ti were also present in propolis, while Co, Cr, Cu, Mo, Ni, Sr, and V were found in trace. Toxic elements such as Pb, As, and Cd were found in the trace. Kruskal-Wallis tests differentiate groups of samples by geographical origin. The presence of B, Fe, Sr, Ti, Zn, and As demonstrated statistical significance between six regions of Serbia.

AB  - PET hydrolases are enzymes that have been shown to act upon PET as a substrate. Theseenzymes usually adopt an α/β hydrolase fold and are from the classes of esterases, lipases,cutinases, and hydrolases.Here, we have done sequence alignment by ClustalW of the sequences corresponding tothe entries available in the PAZy database (pazy.eu) with the addition of a highly efficientI. sakaiensis PETase mutant W159H/S238F and analyzed the results. The aligned sequencesincluded several different well-aligned segments, which were as follows: 18 single-amino acidsegments, 13 two-amino acid segments, 10 three-amino-acid segments, 1 four-amino acidsegment, 1 six-amino acid segment and 1 eight-amino acid segment. Additionally, at position238, which is adjacent to a highly conserved His237, the most common amino acids wereF,T, S, Y, W, L and G, whereas at position 159, the most common amino acids were W, H, I andL, flanked by a conserved three- and eight-amino acid region. These positions seem to becritical for the improvement of the PET hydrolytic activity based on the comparison ofI. sakaiensis PETase mutant W159H/S238F and wt enzyme.Using AlphaFold 2.0 we have predicted the structures of all enzymes available in the databasewhose structures haven't been previously reported and the presence of the α/β hydrolasemotif has been observed.

AB  - Polyethylene terephthalate (PET) is a widely used plastic material. Due to its convenient physicochemical properties, it has become irreplaceable in many scientific, industrial, medical and everyday uses, leading to an accumulation of this material in the environment and initiating many ecological problems, especially in marine ecosystems. One of the solutions for overcoming this  ecological threat may be found in recombinantly produced PET degrading enzymes.
The genes encoding proteins with prominent PET hydrolyzing activity (PETases) that have been successfully produced in Escherichia coli are commercially available (Addgene #112203 and #162667). These genes encode Ideonella sakaiensis PETase mutant W159H/S238F, and the fusion of the wild-type enzyme to MHETase (I. sakaiensis mono-(2-hydroxyethyl)terephthalic acid hydrolyzing enzyme).
Initially, we have done sequence alignment by ClustalW of the sequences corresponding to the entries available in the PAZy database (pazy.eu/doku.php) that contains information on many PET-degrading enzymes. We have identified amino acid substitutions that might be of interest for mutation towards improving the PET hydrolytic activity of IsPETase: at position W159 substitutions into H, I and L and at position S238 substitutions into F, T, Y, W, L and G. Since we are aiming to produce all of the abovementioned (double) mutants, we used different bioinformatic tools to predict the expression solubility of the mutated enzymes. To evaluate the accuracy of the available tools we have tested the expression levels and solubility of IsPETase W159H/S238F and IsPETase-MHETase fusion in E. coli. The IsPETase W159H/S238F protein was expressed fully soluble only at 20 oC, whereas the larger (~92 kDa) IsPETase-MHETase fusion protein was insoluble in all tested conditions. NetSolP (services.healthtech.dtu.dk/services/NetSolP-1.0/) gave the most accurate solubility predictions for the tested proteins and we used it for prediction of the solubility of the aimed mutants.

AB  - Rhenium complexes merit particular attention in the area of metallodrug design due to
rhenium’s broad spectrum of oxidation states and consequently, the possibility to design
compounds of great structural diversity [1,2]. Thus, the synthesis, chemical characterization,
and antitumor activity in vitro of the six Re(V) complexes are described. Novel compounds
were obtained via reaction of [ReOCl3(PPh3)2] with corresponding ligands (pyridine-2-
carboxylic acid, 3-methylpyridine-2-carboxylic acid, 6-methylpyridine-2-carboxylic acid, 2,3-
pyridinedicarboxylic acid, 2,5-pyridinedicarboxylic acid, and 2,6-pyridinedicarboxylic acid) in
acetonitrile or dichloromethane/methanol at 78 °C for 3h. The complexes were fully
characterized using NMR, IR, MS, and elemental analysis. Results of X-ray diffraction analysis
for three of these compounds confirmed the proposed octahedral geometry with bidentate
coordinated ligands, via both oxygen and nitrogen atoms. The antiproliferative effect was
determined by MTT assay. All complexes expressed moderate to low cytotoxic potential.
Complex with pyridine-2-carboxylic acid showed dose-dependent cytotoxic potential,
particularly toward triple-negative breast adenocarcinoma cells MDA-MB-231 and pancreatic
adenocarcinoma cells PANC-1. Drug combination studies in PANC-1 cells with that complex
and Verapamil hydrochloride (VRP) showed a slight arrest of the cell cycle in the S phase and
also increase its antiproliferative potential.

AB  - Ruthenium complexes with dipyrido[3,2-a:2’,3’-c]phenazine (dppz) ligands have been
extensively investigated as potential anticancer agents due to possibility of modulation of their
intracellular accumulation and respective anticancer mechanism of action [1,2]. In recent years
we have explored the anticancer activity of a variety of ruthenium(II)-arene complexes with
dppz based ligands and some of them demonstrated remarkable cytotoxic activity [3].
Following these studies here we present a series of Ru(II)-arene complexes with the general
formula [(η6-arene)Ru(dppz-R)Cl]PF6, where arene fragment was benzene, toluene or pcymene and R was -NO2, -Me or -COOMe with aim to study influence of both of half-sandwich
Ru(II)-arene fragments and the variation of dppz ligands on improvement of the therapeutic
potential of those complexes. All compounds were fully characterized by physico-chemical
methods. The anticancer activity of dppz ligands and respective Ru complexes was assessed
against MDA-MB-231, HCT116 and CT26 cancer cell lines and healthy MRC5 lung
fibroblasts. In vivo efficacy of lead Ru-dppz complex revealed significantly reduction of tumor
burden in mice with colorectal cancers without inducing liver and kidney toxicity. Thus, all the

abstract = "Ruthenium complexes with dipyrido[3,2-a:2’,3’-c]phenazine (dppz) ligands have been
extensively investigated as potential anticancer agents due to possibility of modulation of their
intracellular accumulation and respective anticancer mechanism of action [1,2]. In recent years
we have explored the anticancer activity of a variety of ruthenium(II)-arene complexes with
dppz based ligands and some of them demonstrated remarkable cytotoxic activity [3].
Following these studies here we present a series of Ru(II)-arene complexes with the general
formula [(η6-arene)Ru(dppz-R)Cl]PF6, where arene fragment was benzene, toluene or pcymene and R was -NO2, -Me or -COOMe with aim to study influence of both of half-sandwich
Ru(II)-arene fragments and the variation of dppz ligands on improvement of the therapeutic
potential of those complexes. All compounds were fully characterized by physico-chemical
methods. The anticancer activity of dppz ligands and respective Ru complexes was assessed
against MDA-MB-231, HCT116 and CT26 cancer cell lines and healthy MRC5 lung
fibroblasts. In vivo efficacy of lead Ru-dppz complex revealed significantly reduction of tumor
burden in mice with colorectal cancers without inducing liver and kidney toxicity. Thus, all the
results indicated that introducing appropriate dppz into ruthenium-arene scaffold was a
promising strategy for developing potent antitumor agents.",

AB  - Molecularly imprinting technology was applied for preparing selec­tive sorbents for benzophenone-4 (BP4), an organic UV filter used in sun­screens and cosmetics. Several imprinted polymers were prepared by bulk polymerization, using BP4 as template. Combination of stability (mechanical and chemical), selectivity and robustness of the imprinted polymers with BP4 properties resulted in a successful imprinting process (imprinting factors in range 1.05–2.60). The prepared polymers were characterised by infrared spec­tro­scopy, elemental analysis, conductometric titrations and nitrogen physi­sorp­tion at 77 K. Adsorption capacities and selectivity towards 7 other organic UV filters (benzophenone-3, benzophenone-8, homosalate, butyl methoxydi­ben­zo­ylmethane, ethyl hexyl salicylate, ethyl hexyl p-dimethylamino benzoate and ethyl hexyl p-methoxycinnamate) were determined, proving high adsorption capacity and high selectivity for BP4 binding. The highest adsorption capacity was observed for 4-vinylpyridine/ethylene glycol dimethacrylate co-polymer prepared in dimethyl sulfoxide (1.108 mmol g-1). The imprinted polymer with the highest binding capacity was applied to solid phase extraction of BP4 from aqueous solutions with 98.5 % efficiency.
