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  - Metals and metal oxides have subpar antibacterial activities compared to those of small-molecule antibiotics, yet there are hopes that with proper compositional and structural adjustments this gap might be bridged. In this study, titanium dioxide (TiO2) nanoparticles were mechanically activated and combined with particulate silver through simple reduction process elicited by UV irradiation and assisted with the ultrasound. The resulting powders in various combinations (Ag vs. no Ag, activated vs. non-activated) were characterized using a range of experimental techniques and assessed for their antibacterial activities. The preparation procedure presented in this work prevails over the disadvantages of many chemical routes, most critically by avoiding the use of toxic substances. The mechanical activation did not reduce the particle size or crystallinity of TiO2 nor did it consistently alter the bandgap, yet it enabled the doubling of the amount of silver incorporable into the material. Further, while both mechanical activation and the addition of silver in the amount not exceeding 0.5 wt% produced barely detectable structural changes in the material, they both augmented its antibacterial activity. The precursor TiO2 powder produced no inhibition zone against any of the four bacterial species tested, while the mechanical activation of TiO2 led to the formation of distinct inhibition zones against each of the four bacterial species tested. The addition of silver to activated TiO2 further widened the inhibition zones and it also imparted the antibacterial activity to non-activated TiO2. The boost in the antibacterial activity achieved by the short mechanical activation was of a similar magnitude as the boost obtained after the addition of silver. The antibacterial activity was not different for different species when no silver was added to the system. However, with the addition of silver, species selectivity was obtained, as the composites were more effective against the two Gram-negative species (Escherichia coli and Klebsiella pneumoniae) than against the two Gram-positive ones (Staphylococcus aureus and Bacillus subtilis). The antibacterial activity increased with the addition of silver in the broth assay, but it was mediocre compared to that detected in the agar assay, attesting to the poor dispersability of the powders and their best performance when the bacterial cells migrate to the composite surface than vice versa. The findings of this study give hope that with appropriate microstructural or compositional alterations, the antibacterial activity of metal oxide powders and inorganic materials in general can be made comparable to that of small-molecule antibiotics.

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.

AB  - Novel allergen immunotherapy (AIT) approaches necessitate the use of more effective and safe therapeutics, which can be accomplished by employing novel adjuvants for improved innate immune cell activation, as well as hypoallergenic allergen forms. In this study, we investigate the immunomodulatory effects of a chimera rBet v 1a-BanLecwt (rBv1a-BLwt; Cwt) composed of the major birch pollen allergen Bet v 1a and banana lectin (BanLecwt; BLwt) and two novel chimeras, rBv1l-BLH84T (rBet v 1l-BanLecH84T; C1) and rBLH84T-Bv1l (rBanLecH84T-Bet v 1l; C2), both composed of BLH84T and hypoallergenic birch pollen allergen Bv1l in the co-culture model Caco-2/THP-1, and PBMCs from donors with birch pollen allergy. The chimeric molecules rBv1l-BLH84T (C1) and rBLH84T-Bv1l (C2) were created in silico and then produced in E. coli using recombinant DNA technology. Real-time PCR analysis of gene expression following compound treatment in the co-culture model revealed that all three chimeras have the potential to induce the anti-inflammatory cytokine IL-10 gene expression in Caco-2 cells and IFN-γ gene expression in THP-1 cells. Sandwich ELISA revealed that Cwt increased IL-10 secretion and IFN-/IL-4 levels in PBMCs from birch pollen allergic donors, whereas C1 and C2 were less effective. The findings suggest that Cwt should be analyzed further due to its potential benefit in AIT.

AB  - In this work, we successfully prepared a modified cobalt oxide (Co3O4) carbon paste electrode to detect Levofloxacin (LEV). By synthesizing Co3O4 nanoparticles through the chemical coprecipitation method, the electrochemical properties of the electrode and LEV were thoroughly investigated using CV, SWV, and EIS, while material properties were scrutinized using ICP-OES, TEM, SEM, and XRD. The results showed that the prepared electrode displayed a better electrocatalytic response than the bare carbon paste electrode. After optimizing SWV, the electrode exhibited a wide linear working range from 1 to 85 μM at pH 5 of BRBS as the supporting electrolyte. The selectivity of the proposed method was satisfactory, with good repeatability and reproducibility, strongly suggesting a potential application for determining LEV in real samples, particularly in pharmaceutical formulations. The practicality of the approach was demonstrated through good recoveries, and the morphology of the materials was found to be closely related to other parameters, indicating that the developed method can provide a cost-effective, rapid, selective, and sensitive means for LEV monitoring. Overall, this project has made significant progress towards developing a reliable method for detecting LEV and has opened up new opportunities for future research in this field.

AB  - The concept of the genus Clinopodium L. has changed considerably since its first description. Most of the currently accepted species of the genus have traditionally been treated as separate genera in the group Satureja sensu lato: Clinopodium L., Calamintha sensu Miller or Moench, and Acinos sensu Miller or Moench. This study aimed to gain a better insight into the species diversity of Clinopodium L. from the Balkans by analyzing the taxa that have traditionally been placed in separate genera. The alkane profile and the micromorphological characteristics of the leaves are analyzed. The leaves are visualized using scanning electron microscopy, and alkanes are isolated using n-hexane as a solvent and analyzed using gas chromatography/mass spectrometry. The alkane profile showed the differentiation of the Acinos-group from the other taxa based on the dominant n-C31, while most of the other taxa contained n-C33 as the dominant alkane. The micromorphological features also showed clear differences between the previously recognized genera, especially in the capitate trichomes. The results showed that micromorphological patterns are highly variable in certain groups of the genus Clinopodium.

AB  - In the present work, a nanocomposite, based on embedding Co-doped CeO2 nanoparticles into graphitic carbon nitride (g-C3N4), was applied to functionalize commercial glassy carbon paste. This is the first application of the electrochemical sensor, developed through the proposed procedure, in electrochemical sensing. The sensor was utilized for the electrochemical determination of organophosphate pesticide fenitrothion (FNT). Cyclic voltammetry identified reversible oxidation of FNT (oxidation at 0.18 V and reduction at 0.13 V) and additional reduction at 0.62 V vs. Ag/AgCl in HCl solution (pH =1). Theoretical calculations were carried out to model and elucidate experimentally observed redox processes. Special attention was devoted to modeling experimental conditions, and based on the obtained results, a detailed redox mechanism of the investigated analyte was proposed. This represents the first complete and unambiguous elucidation of the FNT redox mechanism, supported by joined experimental and theoretical data. Square wave voltammetry (SWV) was utilized for quantification, whereby the FNT oxidation peak was chosen for monitoring the analyte concentration. The developed sensor provided a nanomolar detection limit (3.2 nmol L 1), a wide linear concentration range (from 0.01 to 13.7 μmol L 1), and good precision, repeatability, and selectivity towards FNT. Practical application possibility was explored by testing the sensor performance for examining tap water and apple samples. Recovery tests, conducted during the FNT-spiked sample assays, showed a great application capability of the developed sensor for real-time monitoring of FNT traces in environmental samples.

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.

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.

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

Реакција је  довела до формирања бинуклеарног Cu(II)комплекса који садржи два азидна моста у „end-to-end“ (di-mu-1,3-N3) моду, као и два NNO-донорска хидразонска лиганда који заједно формирају аксијално издужену квадратно-пирамидалну геометрију око   сваког централног металног јона. Овај „end-to-end“ (di-mu-1,3-N3) азидни мост се до сада није појављивао у структурама бакар(II) комплекса који садрже NNO-донорске хидразонске лиганде, што чини структуру комплекса још   интересантнијом за  будућа испитивања. Овај    комплекс је  окарактерисан елементалном анализом, ИЦ   спектроскопијом и  рендгенском структурном анализом и пронађено је  да   кристалише у  триклиничној просторној групи P–1 са   асиметричном јединицом која се састоји из једног Cu(II)центра, цвитер-јонског лиганда (L), једног азидног лиганда (N3−) и BF4−контра-јона. Испитивање антимикробне активности комплекса показало је вишу антифунгалну активност, као и вишу антибактеријску активност према Грам-позитивним бактеријама, у односу на сам хидразонски лиганд, док је антифунгална активност комплекса чак упоредива са активношћу амфотерицина Б који је коришћен као стандард.

AB  - Mn(II) and Fe(III) complexes with condensation product of thiosemicarbazide and 2-acetylthiazole have been synthesized and characterized by single-crystal X-ray diffraction. Two complexes have the same ligand system – bis tridentate coordination of the thiosemicarbazone ligand through the NNS donor set of atoms. Furthermore, the central metal ions in both cases have the same d5
 electronic configuration. However, measured magnetism and analysis of the crystal geometries 
show that these two complexes have a different number of unpaired electrons. We 
rationalized the results by electronic structure calculations based on density functional 
theory. High-spin Mn(II) complex has trigonal-prismatic geometry with ionic metal-ligand bonding. Hund's rule of maximum multiplicity is responsible for its sextet spin-ground state. On the other hand, low-spin Fe(III) complex has octahedral coordination and strong metal-ligand covalency with delocalization of spin density toward ligands. Low-spin, doublet state is favored because of the nephelauxetic effect, i.e., smaller pairing energy in Fe(III) complex. Our results show that the difference in the electronic structure of the two complexes, i.e., different spin-ground states, directly affects these molecules' structure, magnetism, reactivity, and biological activities.

Low-spin, doublet state is favored because of the nephelauxetic effect, i.e., smaller pairing energy in Fe(III) complex. Our results show that the difference in the electronic structure of the two complexes, i.e., different spin-ground states, directly affects these molecules' structure, magnetism, reactivity, and biological activities.

abstract = "Mn(II) and Fe(III) complexes with condensation product of thiosemicarbazide and 2-acetylthiazole have been synthesized and characterized by single-crystal X-ray diffraction. Two complexes have the same ligand system – bis tridentate coordination of the thiosemicarbazone ligand through the NNS donor set of atoms. Furthermore, the central metal ions in both cases have the same d5 electronic configuration. However, measured magnetism and analysis of the crystal geometries show that these two complexes have a different number of unpaired electrons. We rationalized the results by electronic structure calculations based on density functional theory. High-spin Mn(II) complex has trigonal-prismatic geometry with ionic metal-ligand bonding. Hund's rule of maximum multiplicity is responsible for its sextet spin-ground state. On the other hand, low-spin Fe(III) complex has octahedral coordination and strong metal-ligand covalency with delocalization of spin density toward ligands.

AB  - The HL ligand, (E)-2-(1-(thiazol-2-yl)ethylidene)hydrazine-1-carbothioamide, was obtained  from the condensation reaction of thiosemicarbazide and 2-acetylthiazole in water. The reaction  of the HL ligand with the metal salt MnCl2·4H2O in a molar ratio 1:1 in methanol/water mixture  results in the formation of bis Mn(II) complex with composition [MnL2]. Complex 1 crystallizes  in the triclinic crystal system with space group P−1. The Mn(II) ion is hexacoordinated with two  tridentate ligands L through NNS sets of donor atoms. The geometry around the Mn is described  as a distorted trigonal prism (Fig. 1). The reaction of the ligand HL with Fe(BF4)2·6H2O in a molar ratio 1:1 in methanol results in the  formation of bis Fe(III) complex with composition [Fe(L)2]BF4·H2O. The Fe(III) ion with L  form six-coordinate complex in which two deprotonated ligand molecules coordinate in a mer  arrangement, forming a distorted octahedral complex by chelation through NNS sets of donor  atoms (Fig. 1). Complex 2 crystallizes in the orthorhombic crystal system with space group Pbca.

AB  - The ligand (E)-2-(1-(thiazol-2-yl)ethylidene)hydrazine-1-carbothioamide (HL1 ) was obtained  from the condensation of 2-acetylthiazole and thiosemicarbazide. Upon reacting HL1 with  Zn(BF4)2·6H2O and NaN3 in a solvent mixture of water/methanol, mononuclear Zn(II) complex  1 with the composition [ZnL1 (N3)2] was obtained. In complex 1, Zn(II) is pentacoordinated with  the thiazole nitrogen, the azomethine nitrogen, and thiolate sulfur atoms from the deprotonated  hydrazone ligand, as well as with two azido ligands. Complex 1 crystallises in the monoclinic  crystal system with space group No.14 (P21/c cell setting). The unit cell of 1 contains four  [ZnL1 (N3)] asymmetric units. In complex 1, the Zn(II) site shows a distorted geometry, almost  midway between the square pyramid and trigonal bipyramid, established on the basis of a  calculated τ5 parameter of 0.46. The hydrazone ligand (E)-1-(2-oxo-2-(2-(1-(pyridin-2-yl)ethylidene)hydrazinyl)ethyl)-pyridine1-ium chloride (HL2 Cl) was obtained from the condensation reaction of 2-acetylpyridine and  Girard's P reagent. Reaction of HL2 Cl with Zn(BF4)2·6H2O and NaN3, in a mixture of  acetonitrile/water/methanol, gives mononuclear Zn(II) complex 2 with the composition  [ZnL2 (N3)2]. Reaction of HL2 Cl with Zn(BF4)2·6H2O and NaN3, in a mixture of  acetonitrile/water/methanol, gives mononuclear Zn(II) complex 2 with the composition  [ZnL2 (N3)2]. In complex 2, the Zn(II) ion has fivefold coordination with NNO-set of donor  atoms of L2 and two nitrogen atoms from the azido ligands. The calculated τ5 value of 0.08 for  [ZnL2 (N3)2] indicates that the five-coordination geometry of the Zn(II) ion is slightly distorted  square pyramidal. Evaluation of the catalytic properties of the Zn(II) complexes in the KA2 reaction shows that the  most active compound, when used as a catalyst, is complex 1. It leads to a 92 % isolated yield of  the desired propargylamine product. The catalytic activity results are in full agreement with the  findings of the DFT calculations. Complex 1 shows the highest value of molecular softness and  the lowest value of molecular hardness. This correlation, between experimental and theoretical  results, is excellently visualised in the linear relationship between the isolated yield of the  desired propargylamine product and the calculated molecular softness, S.

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

The reaction led to the formation of a binuclear Cu(II) complex containing two end-to-end (di-m-1,3-N3) azide bridges, as well as two NNO-donor hydrazone ligands, forming an axially elongated square pyramidal geometry around each Cu(II) center. This end-to-end (di-m-1,3-N3) azide bridge binding mode has not yet occurred in Cu(II) complexes containing the NNO-donor hydrazone ligands, which makes the structure of the complex even more interesting for further studies. The complex was characterized by elemental analysis, IR spectroscopy and X-ray crystallography, and it was found that it crystallizes in the triclinic space group P–1 with the asymmetric unit comprising one Cu(II) centre, zwitterionic ligand L, one azide (N3−) ligand, and BF4− counter anion. Examination of antimicrobial activity of the complex shows higher antifungal and antibacterial activity towards tested Gram-positive bacteria in comparison to the hydrazone ligand, with the antifungal activity of the complex even being comparable to the activity of amphotericin B.",
