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  - Copper(II) complexes with an α-diimine show a wide variety of biological activities, such as antibacterial, antifungal, antioxidant and anticancer. In this work, we synthesized and structurally characterized two novel Cu(II) complexes with methyl 3-formyl-4-hydroxybenzoate (HL) and α-diimines: 2,2′-bipyridine (bipy) and 1,10-phenanthroline (phen). Crystal structure analysis shows that the formulas of the compounds are [Cu(bipy)(L)(BF4)] (1) and [Cu(phen)(L)(H2O)](BF4)·H2O (2), with BF4− as a ligand in complex 1, which is rarely coordinated to metals. Both complexes have a square pyramidal geometry, while DFT calculations showed that the most stable structures of complexes 1 and 2 in a water/DMSO mixture are square-planar derivatives [Cu(bipy)(L)]+ and [Cu(phen)(L)]+. The antibacterial activity of compounds was evaluated in vitro on four Gram-negative and four Gram-positive bacterial strains. Complex 2 showed greater antibacterial activity towards all bacterial strains comparable to the control compound Amikacin. Complex 2 exerted a strong cytotoxic effect against the tested cancer cell lines (IC50 values ranging from 0.32 to 0.44 μM). Both complexes caused apoptotic cell death in HeLa cells and a noticeable in vitro antiangiogenic effect. In the concentration range of 5 to 100 μM, the complexes showed the absence of a genotoxic effect and displayed a protective effect against oxidative DNA damage induced by H2O2 in human peripheral blood cells. The interaction between the compounds and calf–thymus DNA was evaluated by diverse techniques suggesting a tight binding, which was also confirmed by molecular docking. In addition, it was found that the complexes bind tightly and reversibly to bovine and human serum albumin.

AB  - Hemiacetals of cyclopropanone can be isolated and stocked, contrary to their highly reactive parent ketone.  However, they are not readily converted to cyclopropanone, which limits their use as its synthetic equivalents.  2,2,2-trifluoroethoxy hemiacetals are expected to be better cyclopropanone surrogates, however, they have  never been prepared, so far. We show that oxyallyl cations with a heteroatom in the -position can be  intercepted with 2,2,2-trifluoroethanol, with formation of cyclopropanone trifluoroethoxy hemiacetals stable  enough to be isolated, purified and characterized. These species can serve as synthetic equivalents of  cyclopropanone under mild conditions.

AB  - The solubility profile of a drug typically consists of two independent curves that intersect 
at a specific point called pHmax. At pHmax, both salt and base coexist as solid phases. While 
two solids coexist, pH and solubility in the heterogeneous system remain constant 
(according to the Gibbs Phase Rule). Recent studies, however, have shown that pH and 
solubility might change during the salt-to-free-base transformation. This pH range, 
containing two solids, is termed the pHmax – pHmin range. pHmax refers to the pH value at 
the maximum solubility of a eutectic mixture, whereas pHmin represents the pH value at the 
minimum solubility of the eutectic mixture. The objective of this study was to investigate 
the influence of suspension concentration (the ratio of drug mass to suspension volume) on 
the pHmax – pHmin range during solubility determination using the pH-Ramp shake-flask
method. Nortriptyline hydrochloride (Nor, monoprotic base) and atorvastatin calcium (At, 
monoprotic acid) were employed as model compounds. Results indicate that the pHmax –
pHmin range increases as suspension concentration rises (for 20.10 mg NorHCl/mL: 
pHmax=3.55, ΔpH=0; for 59.82 mg NorHCl/mL: pHmax – pHmin= 3.56 – 4.52, ΔpH=0.96). 
Understanding the details of the pHmax – pHmin range could significantly impact product

AB  - Blue C-phycocyanin (C-PC), the major Spirulina protein with innumerable health-promoting
benefits, is an attractive colourant and food supplement. A crucial obstacle to its more extensive
use is its relatively low stability. This study aimed to screen various food-derived ligands for their
ability to bind and stabilise C-PC, utilising spectroscopic techniques and molecular docking. Among twelve examined ligands, the protein fluorescence quenching revealed that only quercetin, coenzyme Q10 and resveratrol had a moderate affinity to C-PC (Ka of 2.2 to 3.7 × 105 M–1). Docking revealed these three ligands bind more strongly to the C-PC hexamer than the trimer, with the binding sites located at the interface of two (αβ)3 trimers. UV/VIS absorption spectroscopy demonstrated the changes in the C-PC absorption spectra in a complex with quercetin and resveratrol compared to the spectra of free protein and ligands. Selected ligands did not affect the secondary structure content, but they induced changes in the tertiary protein structure in the CD study. A fluorescence-based thermal stability assay demonstrated quercetin and coenzyme Q10 increased the C-PC melting point by nearly 5 ◦C. Our study identified food-derived ligands that interact with C-PC and improve its thermal stability, indicating their potential as stabilising agents for C-PC in the food industry.

Selected ligands did not affect the secondary structure content, but they induced changes in the tertiary protein structure in the CD study. A fluorescence-based thermal stability assay demonstrated quercetin and coenzyme Q10 increased the C-PC melting point by nearly 5 ◦C. Our study identified food-derived ligands that interact with C-PC and improve its thermal stability, indicating their potential as stabilising agents for C-PC in the food industry.",

AB  - The widespread usage of the herbicide glyphosate calls for urgent action, aiming at the development of new, 
simple, low-cost, and eco-friendly detection approaches. In the last decade, investigation of graphene quantum 
dots (GQDs) as potential optical probes for various pollutants rapidly grew, thanks to their easy-manipulative 
structure, remarkable photoluminescence (PL) in the visible part of the spectrum, good dispersibility, biocom patibility, and non-toxicity, as well. Herein, a fast, simple, and environmentally friendly method for GQDs 
structural modification is presented. GQDs raw powder was exposed to γ- rays at three different doses (100, 200, 
and 300 kGy) in air, without any solvent or reagents. Irradiation of dots under such affordable conditions led to 
the additional incorporation of oxygen-containing moieties in the GQD structure. For the first time, oxygen-rich 
GQDs irradiated at a 300 kGy dose were successfully applied as direct turn-off PL probe for glyphosate detection. 
The high coefficient of determination (R-squared (R2
) = 0.99) and very low limit of detection (3.02 μmol L-1) 
reveal good linearity between the potential sensor and analyte, as well as sensitivity. Glyphosate was successfully 
detected in celery samples, with a recovery value of 107 ± 0.85%. To evaluate the biological safety of the 
proposed sensing probe, [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] (MTT) and the hemolysis assays were performed. Obtained results show that irradiated and non-irradiated GQDs did not cause the 
death of MRC-5 cells, and hemolysis of erythrocytes. The obtained results demonstrate that GQDs irradiated in an 
air medium can be potentially applied for glyphosate detection.

AB  - In this study,we conducted a comprehensive investigation of newly synthesized fullerene derivatives developed for potential application in perovskite solar cells (PSCs). We explored three novel dihydrofuran-fused C60 fullerene derivatives (13, 14, and 15) that we respecifically designed to enhance solubility and interaction with the substrate, fluorine-dopedtinoxide (FTO). A comparative analysis was performed, with reference to the widely used phenyl-C61-butyric acid methyl ester (PCBM) and compound 12, from which 13, 14, and 15 are derived, to assess the impact of sugar units on materials properties.The synthesized compounds demonstrated significant solubility in common organic solvents, a critical factor in their potential application in wet-processed PSCs. Our investigation included electrochemical property analysis, thin film deposition, surface characterization, and electrochemical impedance spectroscopy (EIS). EIS measurements unveiled key in sights into charge transfer properties at the electrode/electrolyte interface, making the compounds attractive candidates for electron transport layers (ETLs) in PSCs.

AB  - The widespread abuse of traditional antibiotics has led to a global rise in antibiotic-resistant bacteria, which give in return unprecedented health risks. Therefore, there is a large and urgent need for the development of new, smart antibacterial agents able to efficiently kill or inhibit bacterial growth. In this study, we investigated the antibacterial activity of S, N-doped Graphene Quantum Dots (GQDs) as a light-triggered antibacterial agent. Gamma irradiation was employed as a tool to achieve one-step modification of GQDs in the presence of L-cysteine amino acid as a source of heteroatoms. X-ray Photoelectron Spectroscopy (XPS), nuclear magnetic resonance (NMR), and zeta potential measurements provided the necessary data to clarify the structure of modified dots and verify the introduction of both S- and N-atoms in GQDs structure, but also severe changes in the aromatic, sp2 domains. Namely, γ-irradiation caused a bonding of S atoms in 1.14 at.% mainly as thiol groups, and N in 1.81 at.% as amino groups, but sp2 contribution in GQD structure was lowered from 63.00 to 4.86 at.%, as measured in dots irradiated at a dose of 200 kGy. Fluorescence quenching measurements showed that L-cysteine-modified dots are able to bind to human serum albumin. The antibacterial activity of GQDs combined with 1 and 6 h of blue light (470 nm) irradiation was tested against 8 bacterial strains. GQD-cys-25 sample provided the best results, with minimum inhibitory concentration (MIC) as low as 125 μg/mL against S. aureus, E. faecalis, and E. coli after only 1 h of blue light exposure.

AB  - Fe(III) and Mn(II) complexes with condensation product of thiosemicarbazide and 2-acetylthiazole (HL1, (E)-2-(1-(thiazol-2-yl)ethylidene)hydrazine-1-carbothioamide) have been synthesized and characterized by single-crystal X-ray diffraction, IR spectroscopy, and elemental analysis. In both complexes, the thiosemicarbazone ligand is coordinated in deprotonated form through the NNS donor set of atoms. However, while Fe(III) complex is in the doublet ground state with distorted octahedral geometry, the coordination environment around Mn(II) is distorted trigonal-prismatic, and the sextet state is found to be the ground state. DFT calculations were performed to rationalize spin state preferences, and continuous shape measure describes the deviation from ideal six-coordinated polyhedral geometries in the ground and excited states. Antimicrobial activity (against a panel of Gram-negative and Gram-positive bacteria, two yeast, and one fungal strain), brine shrimp assay, and DPPH radical scavenging activity of both complexes were evaluated, and these results relate to the electronic structure of the complexes.

abstract = "Fe(III) and Mn(II) complexes with condensation product of thiosemicarbazide and 2-acetylthiazole (HL1, (E)-2-(1-(thiazol-2-yl)ethylidene)hydrazine-1-carbothioamide) have been synthesized and characterized by single-crystal X-ray diffraction, IR spectroscopy, and elemental analysis. In both complexes, the thiosemicarbazone ligand is coordinated in deprotonated form through the NNS donor set of atoms. However, while Fe(III) complex is in the doublet ground state with distorted octahedral geometry, the coordination environment around Mn(II) is distorted trigonal-prismatic, and the sextet state is found to be the ground state. DFT calculations were performed to rationalize spin state preferences, and continuous shape measure describes the deviation from ideal six-coordinated polyhedral geometries in the ground and excited states. Antimicrobial activity (against a panel of Gram-negative and Gram-positive bacteria, two yeast, and one fungal strain), brine shrimp assay, and DPPH radical scavenging activity of both complexes were evaluated, and these results relate to the electronic structure of the complexes.",

AB  - Two new Zn(II) complexes bearing tridentate hydrazone-based ligands with NNO or NNS donor atoms were synthesised and characterised by elemental analysis, infrared (IR) and nuclear magnetic resonance (NMR) spectroscopies, and single crystal X-ray diffraction methods. These complexes, together with four previously synthesised analogues, having hydrazone ligands with a NNO donor set of atoms, were successfully employed as catalysts in the ketone-amine-alkyne (KA2) coupling reaction, furnishing tetrasubstituted propargylamines, compounds with unique applications in organic chemistry. DFT calculations at the CAM-B3LYP/TZP level of theory were performed to elucidate the electronic structure of the investigated Zn(II) complexes, excellently correlating the structure of the complexes to their catalytic reactivity.

AB  - The condensation product of 7-acetyl-6-azaindole and Girard’s T reagent ((E)-2-(2-(1-(1H-pyrrolo[2,3-c]pyridin-7-yl)ethylidene)hydrazineyl)-N,N,N-trimethyl-2-oxoethan-1-aminium, HL ligand) was used as a ligand in the reaction with Cu(BF4)2·6H2O and NaN3. The reaction led to the formation of a binuclear Cu(II) complex containing two end-to-end (di-m-1,3-N3) azide bridges, as well as two NNO-donor hydrazone ligands, forming an axially elongated square pyramidal geometry around each Cu(II) center. This end-to-end (di-m-1,3-N3) azide bridge binding mode has not yet been reported, in Cu(II) complexes containing the NNO-donor hydrazone ligands, which makes the structure of the complex even more interesting for further studies. The com­plex was characterized by elemental analysis, IR spectroscopy and X-ray crys­tal­lography, and it was found that it crystallizes in the triclinic space group P–1 with the asymmetric unit comprising one Cu(II) centre, zwitterionic ligand L, one azide (N3-) ligand and BF4- counter anion. Examination of antimicrobial activity of the complex shows higher antifungal and antibacterial activity towards tested Gram-positive bacteria in comparison to the hydrazone ligand, with the antifungal activity of the complex even being comparable to the act­ivity of amphotericin B.

AB  - 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  - Razvoj hemijske industrije u prošlom veku pozitivno je uticao na životni standard, ali je za sobom ostavio značajne količine toksičnih supstanci u životnoj sredini. Dugotrajne organske zagađujuće supstance (Persistant Organic Pollutants - POPs) su antropogene hemikalije koje se zadržavaju, akumuliraju u lancu ishrane i imaju štetne posledice po zdravlje ljudi i životnu sredinu [1]. Per- i polifluoralkil supstance (PFAS) kao što su perfluorooktanska kiselina (PFOA), perfluorooktan sulfonska kiselina (PFOS) i od 2022. godine perfluoroheksan sulfonska kiselina (PFHxS) se nalaze na listi POPs hemikalija [2]. Publikacije proistekle iz istraživanja na temu PFAS supstanci ukazuju da mikroorganizmi koji su izolovani iz životne sredine zagađene ovim jedinjenjima mogu smanjiti količinu istih usled biosorpcije, ali i potencijalne biotransformacije i biodegradacije [3,4].

abstract = "Razvoj hemijske industrije u prošlom veku pozitivno je uticao na životni standard, ali je za sobom ostavio značajne količine toksičnih supstanci u životnoj sredini. Dugotrajne organske zagađujuće supstance (Persistant Organic Pollutants - POPs) su antropogene hemikalije koje se zadržavaju, akumuliraju u lancu ishrane i imaju štetne posledice po zdravlje ljudi i životnu sredinu [1]. Per- i polifluoralkil supstance (PFAS) kao što su perfluorooktanska kiselina (PFOA), perfluorooktan sulfonska kiselina (PFOS) i od 2022. godine perfluoroheksan sulfonska kiselina (PFHxS) se nalaze na listi POPs hemikalija [2]. Publikacije proistekle iz istraživanja na temu PFAS supstanci ukazuju da mikroorganizmi koji su izolovani iz životne sredine zagađene ovim jedinjenjima mogu smanjiti količinu istih usled biosorpcije, ali i potencijalne biotransformacije i biodegradacije [3,4].",

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  - Common to all biological systems and living organisms are molecular interactions, which
may lead to specific physiological events. Most often, a cascade of events occurs, establishing an equilibrium between possibly competing and/or synergistic processes. Biochemical pathways that sustain life depend on multiple intrinsic and extrinsic factors contributing to aging and/or diseases. This article deals with food antioxidants and human proteins from the circulation, their interaction, their effect on the structure, properties, and function of antioxidant-bound proteins, and the possible impact of complex formation on antioxidants. An overview of studies examining interactions between individual antioxidant compounds and major blood proteins is presented with findings. Investigating antioxidant/protein interactions at the level of the human organism and determining antioxidant distribution between proteins and involvement in the particular physiological role is a very complex and challenging task. However, by knowing the role of a particular protein in certain pathology or aging, and the effect exerted by a particular antioxidant bound to it, it is possible to recommend specific food intake or resistance to it to improve the condition or slow down the process.

AB  - Chemotaxonomy presents various challenges that need to be overcome in order to obtain valid and reliable results. Individual genetic and environmental variations can give a false picture and lead to wrong conclusions. Applying a holistic approach, based on multivariate data analysis, these challenges can be overcome. Thus, a metabolomics approach has to be optimized depending on the subject of research. We used 1H NMR-based metabolomics as a potential chemotaxonomic tool on the selected Euphorbia species growing wild in Serbia. Principal components analysis (PCA), soft independent modeling by class analogy (SIMCA) and Orthogonal Projections to Latent Structures Discriminant Analysis (OPLS-DA) were used to analyze obtained NMR data in order to reveal chemotaxonomic biomarkers. The standard protocol for plant metabolomics was optimized aiming to extract more specific metabolites, which are characteristic for the Euphorbia genus. The obtained models were validated, which revealed that variables unique for each species were associated with certain classes of molecules according to literature data. In E. salicifolia, acacetin-7-O-glycoside (not found before in the species) was detected, and the structure of the aglycone part was solved based on 2D NMR data. In the presented paper, we have shown that metabolomics can be successfully used in Euphorbia chemotaxonomy.

AB  - Bisbibenzyls are specialized metabolites found exclusively in liverworts, until recently; they represent chemical markers of liverworts. Their occurrence in vascular plants was noticed in 2007, when they were found in Primula veris subsp. macrocalyx from Russia. This report prompted us to chemically analyze the two most common Serbian Primula species, P. veris subsp. columnae and P. acaulis, in order to determine the presence of bisbibenzyls in them. Our study revealed nine structurally distinct bisbibenzyls (1–9), identified based on 1D and 2D NMR, IR, UV and HRESIMS data. Among them were five previously undescribed compounds (2–6). The remaining com­ pounds found and previously described in the literature were: the bisbibenzyls riccardin C (1), isoperrottetin A (7), isoplagiochin E (8) and 11-O-demethylmarchantin I (9), as well as 4-hydroxyphenylmethylketone (10) and 4-hydroxy-3-methoxyphenylmethylketone (11). Riccardin C was the most dominant bisbibenzyl in both species studied. Previously, it was the first bisbibenzyl found in vascular plants (P. veris subsp. macrocalyx). An assessment of the cytotoxic activity of the isolated compounds against A549 lung cancer and healthy MRC5 cell lines was also the subject of our study. Compounds 6 and 9 exhibited significant cytotoxic activity expressed by IC50 values of 12 μM, but the selectivity was not satisfactory.

AB  - This paper presents sustainable technology for environmentally friendly composite production. Biobased unsaturated polyester resin (b-UPR), synthesized from waste polyethylene terephthalate (PET) glycosylate and renewable origin maleic anhydride (MAnh) and propylene glycol (PG), was reinforced with unmodified and vinyl-modified biosilica nanoparticles obtained from rice husk. The structural and morphological properties of the obtained particles, b-UPR, as well as composites, were characterized by Fourier-transform infrared spectroscopy (FTIR), nuclear magnetic resonance spectroscopy (NMR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) techniques. The study of the influence of biosilica modification on the mechanical properties of composites was supported by hardness modeling. Improvement of the tensile strength of the b-UPR-based composite at 2.5 wt.% addition of biosilica modified with vinyl silane, named “b-UPR/SiO2-V” composite, has been achieved with 88% increase. The thermal aging process applied to the b-UPR/SiO2-V composite, which simulates use over the product’s lifetime, leads to the deterioration of composites that were used as fillers in commercial unsaturated polyester resin (c-UPR). The grinded artificially aged b-UPR composites were used as filler in c-UPR for the production of a table top layer with outstanding mechanical properties, i.e., impact resistance and microhardness, as well as fire resistance rated in the V-0 category according to the UL-94 test. Developing sustainable composites that are chemically synthesized from renewable sources is important from the aspect of preserving the environment and existing resources as well as the extending their life cycle.

AB  - The aim of this study was to find the chemical parameters for the differentiation of plum
cultivars grown along the fjord areas of Western Norway and Eastern Norway, having specific
agroclimatic conditions. Chemical analysis of the fruits confirmed the contents of 13 quantified
elements, 22 sugar compounds, 11 organic acids, 19 phenolic compounds, and antioxidant activity in
68 plum cultivars. Dominated contents were noted for nitrogen (with the maximum mean value of
3.11%), potassium (8055.80 mg/kg), and phosphorous (7878.88 mg/kg). Averagely, the highest level
of sugars was determined for glucose (244.46 g/kg), fructose (197.92 g/kg), sucrose (208.25 g/kg),
and sorbitol (98.02 g/kg), organic acids for malic acid (24.06 g/kg), and for polyphenol compounds
were 5-O-caffeoylquinic acid (66.31 mg/kg), and rutin (58.06 mg/kg). Applied principal component
analysis has been useful for distinguishing the plum cultivars from three areas in Norway where
copper, iron, potassium, magnesium, manganese, and sodium; sucrose, ribose, maltose, and raffinose;
p-hydroxybenzoic acid, rutin, ferulic acid, kaempferol 7-O-glucoside, p-coumaric acid, and 5-Ocaffeoylquinic acid were the most influential. In regard to human health and future breeding work
that will have the aim to produce functional food with high health-related compounds, the plum
cultivar ‘Mallard’ should be underlined due to the high level of elements, ‘Valor’ due to high sugar
content, ‘Helgøyplomme’ due to content of organic acids, and ‘Diamond’ due to the content of
phenolic compounds.

AB  - Biotechnological and biomedical applications of antibodies have been on a steady rise since the 1980s. As unique and highly specific bioreagents, monoclonal antibodies (mAbs) have been widely exploited and approved as therapeutic agents. However, the use of mAbs has limitations for therapeutic applications. Antibody fragments (AbFs) with preserved antigen-binding sites have a significant potential to overcome the disadvantages of conventional mAbs, such as heterogeneous tissue distribution after systemic administration, especially in solid tumors, and Fc-mediated bystander activation of the immune system. AbFs possess better biodistribution coefficient due to lower molecular weight. They preserve the functional features of mAbs, such as antigen specificity and binding, while at the same time, ensuring much better tissue penetration. An additional benefit of AbFs is the possibility of their production in bacterial and yeast cells due to the small size, more robust structure, and lack of posttranslational modifications. In this review, we described current approaches to the AbF production with recent examples of AbF synthesis in bacterial and yeast expression systems and methods for the production optimization.

AB  - The modern lifestyle has increased our utilization of pollutants such as heavy metals, aromatic compounds, and contaminants that are of rising concern, involving pharmaceutical and personal products and other materials that may have an important environmental impact. In particular, the ultimate results of the intense use of highly stable materials, such as heavy metals and chemical restudies, are that they turn into waste materials, which, when discharged, accumulate in environmental water bodies. In this context, the present review presents the application of metal–organic frameworks (MOFs) in electrochemiluminescent (ECL) sensing for water pollutant detection. MOF composites applied as innovative luminophore or luminophore carriers, materials for electrode modification, and the enhancement of co-reaction in ECL sensors have enabled the sensitive monitoring of some of the most common contaminants of emerging concern such as heavy metals, volatile organic compounds, pharmaceuticals, industrial chemicals, and cyanotoxins. Moreover, we provide future trends and prospects associated with ECL MOF composites for environmental sensing.

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.
