AB  - Triclosan (TCS) is a polychlorinated phenoxy phenol (PCPPs) used as a disinfectant and a broad-spectrum antibacterial and antifungal agent in personal hygiene products. TCS easily forms diphenyl ethers and dioxins, which are persistent organic pollutants. This work used a double approach for the TSC sensing: a) screen-printed (SPE) electrochemical platform for on-site application, modified with lanthanum iron oxide and graphitic carbon nitride composite (LaFeO3/Fe2O3@g-C3N4/SPE); and b) carbon paste electrode (CPE), modified with the same material and used in laboratory conditions. Linear range from 0.1 μM to 10 μM, the limit of detection (LOD) of 29 nM and the limit of quantification (LOQ) of 91 nM were obtained for CP electrode in BRBS pH 8. SPE showed the best analytical parameters in BRBS at pH 3, with a linear range from 0.3 μM to 7 μM, LOD of 0.09 μM and LOQ of 0.28 μM. Furthermore, the influence of potential interferents was investigated and proven to be negligible. Determination of TSC was performed to estimate the environmental impact of this compound as well as the practical usefulness of the proposed sensor in the real sample analysis, confirmed with a HPLC analysis. © 2022 Elsevier B.V.

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  - Stable, water-soluble titanium complexed with mandelic acid was used as a precursor for titanium phosphorus double oxide obtained in hydrothermal conditions in the presence of phosphoric acid. Surprisingly, hydrolysis of organic complexes provided a microstructured sphere with narrow size distribution, low aggregation and a small fraction of morphological irregularities. Obtained microspheres had a complex structure comprised of flakes, whose size could be manipulated with temperature conditions. Samples were found to be electrochemically active against sulcotrione, a well-recognized herbicide. Electrochemical sensors based on the synthesized microspheres were successfully adapted for natural water reservoir analysis and exhibited low levels of detection of 0.61 µM, limit of quantification of 1.86 µM, wide dynamic linear range from 2 to 200 µM, good selectivity, excellent reproducibility and in-time stability.

AB  - In this paper, electrochemical degradation of Reactive Black 5 (RB5) textile azo dye was examined in regard to different synthesis procedures for making PbO2–graphitic carbon nitride (g-C3N4) electrode. The reaction of with ClO− in the presence of different surfactants, i.e., cetyltrimethylammonium bromide (CTAB) and tetrabutylammonium phosphate (TBAP), under conventional conditions, resulted in the formation of PbO2 with varying morphology. The obtained materials were combined with g-C3N4 for the preparation of the final composite materials, which were then characterized morphologically and electrochemically. After optimizing the degradation method, it was shown that an anode comprising a steel electrode coated with the composite of PbO2 synthesized using CTAB as template and g-C3N4, and using 0.15 M Na2SO4 as the supporting electrolyte, gave the best performance for RB5 dye removal from a 35 mg/L solution. The treatment duration was 60 min, applying a current of 0.17 A (electrode surface 4 cm2, current density of 42.5 mA/cm2), while the initial pH of the testing solution was 2. The reusability and longevity of the electrode surface (which showed no significant change in activity throughout the study) may suggest that this approach is a promising candidate for wastewater treatment and pollutant removal.

AB  - There are ten million people in the world who have Parkinson’s disease. The most potent medicine for Parkinson’s disease is levodopa (L-DOPA). However, long-term consumption of L-DOPA leads to the appearance of side effects, as a result of which the control and monitoring of its concentrations are of great importance. In this work, we have designed a new electrochemical sensor for detecting L-DOPA using a carbon paste electrode (CPE) modified with Eu2O3@Cr2O3 composite nanoparticles. Rare earth elements, including Eu, are increasingly used to design new electrode nanocomposites with enhanced electrocatalytic properties. Europium has been considered a significant lanthanide element with greater redox reaction behavior. We conducted a hydrothermal synthesis of Eu2O3@Cr2O3 and, for the first time, the acquired nanoparticles were used to modify CPE. The proposed Eu2O3@Cr2O3/CPE electrode was investigated in terms of its electrocatalytic properties and then used to develop an analytical method for detecting and quantifying L-DOPA. The proposed sensor offers a wide linear range (1–100 µM), high sensitivity (1.38 µA µM−1 cm−2) and a low detection limit (0.72 µM). The practical application of the proposed sensor was investigated by analyzing commercially available pharmaceutical tablets of L-DOPA. The corresponding results indicate the excellent potential of the Eu2O3@Cr2O3/CPE sensor for application in real-time L-DOPA detection.

AB  - Polyurethane (PU) nanocomposites are highly utilized in biomedical devices/implants due to their excellent mechanical properties, good biocompatibility, and low cytotoxicity. These PU nanocomposites with silver nanoparticles are well known potent antimicrobial agents. Biocompatible magnetic nanoparticles such as ferrites has also gained attention especially in various fields of drug delivery, biosensing and magnetic resonance imaging which requires highly specific magnetic nanoparticle (MNP) properties such as uniform size distribution, less agglomeration and stability in the biological medium. Among MNP, copper and zinc ferrites have been broadly applicable in biomedical, optoelectronic, catalysis and drug delivery. With a view to design PU/ferrites nanocomposites and to explore their antimicrobial potential, the present preliminary study reports the preparation of PU nanocomposites with copper ferrite and zinc ferrite (1 wt.%) and with the same composition. The nanocomposites were characterized using water absorption and swelling measurements. The antimicrobial activity of these composites was investigated against four bacterial strains: Staphylococcus aureus, Enterococcus faecium, Pseudomonas aeruginosa, and Klebsiella pneumoniae, and one Candida strain, C. albicans and compared with those of PU nanocomposites with silver ferrite nanoparticles. PU nanocomposites based on zinc and copper ferrites did not show antimicrobial activity, on the contrary they supported microbial attachment and growth. However, PU nanocomposites with silver ferrite did not show significant antibacterial activity but show antifungal activity and it is related with hydrophilicity of the prepared materials.

AB  - Compounds used in the fashion industry effect the water bodies in the vicinity of textile factories, resulting in the visible coloration of surface water. Fe-doped graphite-based in house prepared electrodes were used in the Fenton- -like degradation of Reactive Blue 52 (RB52). The electrodes consisting of high-density graphite in three granulation sizes and three levels of Fe content were characterized using scanning electron microscopy (SEM). The amount of Fe in the electrodes and H2O2 concentration in synthetic textile wastewater were optimized. Additionally, the size of graphite grains was varied to investigate whether it effects the degradation rate. Under only 10 min of electro-Fenton degradation, a system with 10 mmol dm-3 of H2O2 and an electrode made of 7 % of Fe and 70 μm of granulation size of graphite, degraded over 75 % of RB52, and over 99 % after 40 min of treatment. The obtained results indicate that the proposed approach could be beneficial in the field of novel materials for environmental application and that in house prepared carbon could be an excellent replacement for commercially available supports.

AB  - The textile industry is one of the major pollutants of waterbodies with effluents high in biochemical and chemical oxygen demand values, high values of total dissolved solids, total suspended solids, and low dissolved oxygen values along with strong color. The existence of a successful method for its decontamination would be beneficial. In this work, we synthesized sponge-like europium oxide (Eu2O3) using a template-directed route from carbon hollow spheres, obtained from glucose as a carbon source. The material synthesis method was done in an aqueous environment, without using any organic solvents. Electrochemical properties of the synthesized material were investigated using cyclic voltammetry and electrical impedance spectroscopy, while morphological characterization was done using scanning electron microscopy and X-ray powder diffraction analysis. Eu2O3 were successfully immobilized at the surface of a screen-printed carbon electrode (Eu2O3/SPCE) using the drop-casting method. Finally, the prepared electrodes were tested toward the removal of Reactive Blue 52 (RB52) using electrochemical advanced oxidation processes (EAOPs). Important parameters, that is, the supporting electrolyte, its concentration, pH value, and the applied voltage, were optimized for RB52 degradation. The rate of removal was monitored spectrophotometrically and by high-performance liquid chromatography with a diode array detector (HPLC-DAD). It was found that the proposed approach reaches complete decolorization of the RB52 solution after a 60-min treatment, at pH 5.6 of KCl supporting electrolyte at a concentration of 0.05 M. Under optimal parameters, after 3 h of treatment, total organic carbon (TOC) was lowered by ~40%. The obtained results indicate that the proposed method may find potential application in EAOPs, considering electrode stability, durability, and efficiency and simplicity of the method.

AB  - The homemade, porous carbon material, thermolysis prepared from Novolac phenol-formaldehyde resin, in situ modified with Co3O4 nanoparticles and mixed with single-wall carbon nanotubes, was used in selective sensing of prominent antioxidant α-lipoic acid (LA). XRD, SEM and EIS measurements were used for characterization of material composition, structure, morphology and improved conductivity. The quantification of LA at TPCo3O4&SWCNTCPE was done by a square-wave voltammetric technique in BR buffer solution at pH 6. The linear working range was recorded from 2 to 100 μM of LA and the proposed electrode material was successfully applied in the determination of LA in dietary supplements.

AB  - Honokiol is neolignan present in the magnolia bark. It displays versatile pharmacological properties—neuroprotective and anxiolytic effect, anti-cancer activity and antimicrobial effect being the most important. This paper aims to develop a voltammetric non-enzymatic biosensor for honokiol detection, quantification and monitoring in drugs and cosmetic products. The materials used in this study were synthesized and characterized by HR-XRPD, SEM, ATR-FTIR and electrochemical methods. Bi2O3, being a p-type semiconductor, was used as an electrode material. Both its semiconductivity and electrocatalytic properties result from lattice structure defects, which differ on the surface and in the bulk of the bismuth oxide crystal, and therefore are crystal size dependent. The influence of the particle size of Bi2O3 on its electrocatalytic properties was studied, and it was confirmed that Bi2O3 nanoparticles have better overall conductive/resistive and catalytic characteristics than microribbons and that the optimal electrode modification for sensing application was obtained by Bi2O3@SWCNT composite material preparation. Here, we established a sensitive electrochemical sensing platform for honokiol detection based on CP electrode modified with bismuth oxide nanoparticles and SWCNT with the 0.17 μM limit of detection, and linear operating range from 0.1 to 50 μM. The effect of potential interferents on honokiol detection was explored. Obtained results in the interference tests and the real sample analysis suggest that the developed approach is selective, accurate and reproducible. Due to the low detection limit and a wide working range, the proposed sensing platform opens great opportunities for further construction of sensors for honokiol detection and monitoring in the pharmaceutical industry and medicinal chemistry.

AB  - L-DOPA (L-3,4-dihydroxyphenylalanine), the precursor of dopamine, is widely used in the treatment of Parkinson’s disease, thus determining and monitoring the concentration of L-DOPA is of utmost importance for both medical and scientific purposes. Although many analytical approaches, designed for drug detection and quantification, already exist, there is a constant need for modification of old and tailoring of new, faster, and selective methods. Redox active chemical species, such as L-DOPA, can be measured directly by electrochemical means, whereas electrochemical sensors combine sensitivity and selectivity within a small analytical device. This work demonstrates the development of such electrochemical sensor, based on carboxylated single-wall carbon nanotubes (SWCNT-COOH) decorated with SiO2 coated-Nd2O3 nanoparticles, and further application for the detection of L-DOPA. Developed SWCNT-COOH@Nd2O3-SiO2 sensor shows linear response in the range from 2 µmol L−1 to 52 µmol L−1 analyte concentration, and beside the low detection limit, it is characterized by a fast response time, as well as good life-time, reproducibility and repeatability.

AB  - The goal of this work was to develop green electrode material that unites all advantages of domestic made, synthesized porous carbon powder and ceria dioxide nanoparticles known due to exceptional catalytic properties. Thermal decomposition of Novolac phenol-formaldehyde resin and cerium sulfate resulting in producing a high-performance CeO2 porous carbon material highly sensitive to dopamine (DA) electrooxidation. Morphological and structural characteristics of the material were determined by SEM and XRD measurements, while electrochemical characterization was performed by EIS and CV. The sensitivity of DA determination on the proposed CeO2-doped carbon material was enhanced by adding multi-wall carbon nanotubes to finally prepare a mixture for a specific carbon paste electrode (TPCeO2&MWCNT@CPE). SWV technique was used for quantification of dopamine in Britton-Robinson buffer pH 6 in the concentration range of 0.5-100 μM of DA, with the detection limit of 0.14 μM and quantification limit of 0.44 μM. Good selectivity overstudied bioactive compounds enables the successful and efficient application of the proposed electrode and developed an analytical procedure for the determination of dopamine in spiked urine samples.

AB  - Type of the wood used for the aging highly influences the quality of alcoholic beverages. In this research we explored the potential of cyclic voltammetry (CV) and differential pulse voltammetry (DPV) to establish fingerprints characteristic for each wood and to enable determining the type of the wood used in the aging process. Eleven different wood samples were used to prepare three different types of spirits during 15 months. The highest extraction rate was obtained during the first month, while further aging was followed with almost constant amount of extracted polyphenols. Black locust, myrobalan plum, and mulberry extracts were discriminated from the spirits aged in oak and wild cherry wood when statistical analysis was applied. Although clear classification of all samples was not achieved, this long term study demonstrated a potential of both CV and DPV for differentiating wood species used in the aging, hence in the quality control of spirits. © 2020 Elsevier Ltd

AB  - Urban airborne particles contain a wide spectrum of components, known to have harmful effects on human health. This study reports a detailed investigation of fine particulate matter (PM2.5), chemical content and oxidative potential derived from two different urban environments. During summer and winter, 20-day campaigns were conducted at Belgrade city center (urban-background site – UB) and Bor (urban-industrial site – UI). Using various analytical techniques, carbonaceous compounds, water-soluble inorganic ions, major and trace elements were determined, while the oxidative potential of PM2.5 was estimated by dichloro-dihydro-fluorescein diacetate (DCFH-DA) assay (OPDCFH values). The mean PM2.5 concentrations in both urban environments were above the recommended daily value, and the dominant PM2.5 mass contributor was organic matter (29–55%). The OC/EC ratio was significantly higher at UB site during winter, which was an indication of a considerable contribution of secondary organic carbon to the overall organic carbon (OC). Water-soluble organic carbon (WSOC) was also higher at UB than at UI site, and it probably came from the same sources as OC. In general, the different partition of secondary organic aerosol (SOA) in warm and cold periods affected the number of organic components. Sulfates and nitrates were the most abundant ions at both sites and they counted approximately 40% (summer) and 50% (winter) of total ions. Further, the concentrations of the most elements, particularly some potentially carcinogenic elements such as As, Cd and Pb were significantly higher at UI, due to the emissions from the copper smelter complex in the vicinity. The mean OPDCFH values were similar during the summer at both sampling sites, whereas a statistically significant difference between sites was noticed in favor of UB environment in winter.

AB  - Chlorine dioxide (ClO2) degradation of the organophosphorus pesticides azamethiphos (AZA) and dimethoate (DM) (10 mg/L) in deionized water and in Sava River water was investigated for the first time. Pesticide degradation was studied in terms of ClO2 level (5 and 10 mg/L), degradation duration (0.5, 1, 2, 3, 6, and 24 h), pH (3.00, 7.00, and 9.00), and under light/dark conditions in deionized water. Degradation was monitored using high-performance liquid chromatography. Gas chromatography coupled with triple quadrupole mass detector was used to identify degradation products of pesticides. Total organic carbon was measured to determine the extent of mineralization after pesticide degradation. Real river water was used under recommended conditions to study the influence of organic matter on pesticide degradation. High degradation efficiency (88–100% for AZA and 85–98% for DM) was achieved in deionized water under various conditions, proving the flexibility of ClO2 degradation for the examined organophosphorus pesticides. In Sava River water, however, extended treatment duration achieved lower degradation efficiency, so ClO2 oxidized both the pesticides and dissolved organic matter in parallel. After degradation, AZA produced four identified products (6-chlorooxazolo[4,5-b]pyridin-2(3H)-one; O,O,S-trimethyl phosphorothioate; 6-chloro-3-(hydroxymethyl)oxazolo[4,5-b]pyridin-2(3H)-one; O,O-dimethyl S-hydrogen phosphorothioate) and DM produced three (O,O-dimethyl S-(2-(methylamino)-2-oxoethyl) phosphorothioate; e.g., omethoate; S-(2-(methylamino)-2-oxoethyl) O,O-dihydrogen phosphorothioate; O,O,S-trimethyl phosphorodithioate). Simple pesticide degradation mechanisms were deduced. Daphnia magna toxicity tests showed degradation products were less toxic than parent compounds. These results contribute to our understanding of the multiple influences that organophosphorus pesticides and their degradation products have on environmental ecosystems and to improving pesticide removal processes from water.

AB  - The aim of this study was to investigate, analyze, and compare applied techniques suitable for achieving efficient removal of organophosphorus pesticides (OPPs) (malathion and fenitrothion) from aqueous solutions and analyze the degradation products and processes. Pesticide degradation efficiency (%) was monitored by high-performance liquid chromatography (HPLC) equipped with a photodiode array detector (DAD), while mineralization degree was determined by total organic carbon analysis (TOC). Daphnia magna was used for screening the environmental safety aspects of the degradation methods, i.e., for assessing the toxicity of solutions obtained after degradation. Additionally, a surface river water was utilized to examine the likely influence of organic matter on the pesticides’ degradation. Pesticide degradation products were identified using gas chromatography with a triple quadrupole mass detector (GC-MS/MS) as well as ultrahigh-performance liquid chromatography coupled with a linear ion trap, Orbitrap mass spectrometer (UHPLC-LTQ Orbitrap MS), and a simple pesticide degradation mechanism is proposed. Removal of pesticides from water using chlorine dioxide was successful, resulting in high degradation efficiency (98% for malathion and 81% for fenitrothion). Partial mineralization was achieved, and Daphnia magna mortality decreased in the waters containing degradation products (compared with the parent pesticides), indicating that the solutions formed were less toxic than the parent pesticides. Lower degradation rates (80% for malathion and 72% for fenitrothion) in Sava River water were measured, indicating the influence of the organic matter contained in this naturally occurring surface water. The results prove that chlorine dioxide could be used as an agent for successful removal of these OPPs from water.

AB  - Electrochemical degradation procedure for the removal of organic dye Reactive Blue 52 using nano-magnetite-doped carbonaceous electrodes was proposed. The electrode was prepared by calcination of graphite grains mixed with phenol–formaldehyde binder modified with iron nitrate. The morphology and phase composition of the electrodes were investigated using scanning electron microscopy and powder X-ray diffraction. Electrochemical degradation was done in Nafion membrane-divided cell where anodic part was filled with color solution and cathodic with supporting electrolyte. Parameters affecting on decolorization rate were investigated. A high increase in the removal efficiency, under optimized parameters, was noticed using carbon electrodes containing 1 mass% of magnetite in the presence of 3 mM hydrogen peroxide and 7 mass% of magnetite in the presence of 10 mM hydrogen peroxide. Almost 100% decolorization was achieved during 30 min with 62–77% of the mineralization. Based on these results, it can be concluded that this approach offered green, cheap and efficient degradation of reactive dyes and could be used as promising candidate for wastewater processing in the textile industry.

The electrode was prepared by calcination of graphite grains mixed with phenol–formaldehyde binder modified with iron nitrate. The morphology and phase composition of the electrodes were investigated using scanning electron microscopy and powder X-ray diffraction. Electrochemical degradation was done in Nafion membrane-divided cell where anodic part was filled with color solution and cathodic with supporting electrolyte. Parameters affecting on decolorization rate were investigated.

AB  - Background of the study – Among fruits, berry fruits contain a very large complex of chemical compounds that are responsible for their antioxidant properties. As far as we know there is no data available from cyclic voltammetry studies of berry fruits. Objectives – The first objective of the present work was to investigate the electrochemical properties of antioxidants present in four types of berry fruits: strawberries, blackberries, blueberries and red raspberries. The second objective was to establish the correlation between antioxidant capacities obtained from cyclic voltammograms with those obtained using spectrophotometric techniques. Methods – Evaluation of antioxidant activity of 15 berry samples (strawberry, blackberry, blueberry and raspberry) has been carried out using cyclic voltammetry (CV). CVs were taken in the potential range between 0 mV and 800 mV with a scan rate of 100 mV s-1. Results – A pronounced anodic current peak observed between 0.524 V and 0.540 V in all analyzed berry samples can be ascribed to anthocyanins, which are the major contributors to the antioxidant capacity of investigated berries. Results obtained from CVs were compared with those obtained by using DPPH, ABTS, FRAP and RP assays. ACI parameters were determined for each berry sample by assigning all the assays an equal weight. According to obtained results, the highest ACI had blueberry samples, followed by blackberry, raspberry and strawberry samples. Also, high positive correlations were found between antioxidant capacities deduced from CVs with those obtained using FRAP (R2 = 0.8630, p = 0.0006), RP (R2 = 0.7426, p = 0.0004), DPPH (R2 = 0.7680, p = 0.0001) and ABTS (R2 = 0.8710, p = 0.000002). In addition, high positive correlations were also found between total phenols, flavonoids, anthocyanins and CV antioxidant capacity (R2 = 0.8091, p = 0.0005; R2 = 0.8341, p = 0.0002; R2 = 0.7163, p = 0.0007), respectively. Conclusion – Obtained results showed that the cyclic voltammetry is a suitable method for the determination of the reducing capacity based on the electrochemical properties of compounds under the test. © ISHS 2019.

AB  - The degradation of two sulfonylurea herbicides, nicosulfuron and thifensulfuron methyl in water by chlorine dioxide, was studied for the first time in this paper. In order to examine the optimal parameters for degradation of both herbicides, degradation was investigated under light or dark conditions with different amount of chlorine dioxide, different degradation periods, and at different pH values. Degradation efficiency of herbicides was monitored using high-performance liquid chromatography with photodiode array detection (HPLC-DAD). The degradation products were analyzed by gas chromatography with triple quadrupole mass detector (GC–QQQ). Three products were identified after degradation of nicosulfuron and two products after degradation of thifensulfuron methyl. Total organic analysis (TOC) gave insight into some differences in degradation mechanisms and degrees of mineralization after degradation of the herbicides using chlorine dioxide. A simple mechanism of herbicide degradation was proposed. Acute toxicity tests were performed on the products produced after degradation with chlorine dioxide, and the results showed that the degradation products were less toxic than the parent compounds. The findings of the present study are very useful for the treatment of wastewaters contaminated with herbicides. © 2018, Springer Nature Switzerland AG.

AB  - This work present a new approach for the detection of relatively new herbicide pethoxamid (POA), a first electrochemical behavior and determination based on its oxidation on boron-doped diamond electrode in Britton-Robinson buffer solution at pH 4. Square wave voltammetric technique was used for quantification of POA at anodic potential of 1.35 V vs reference Ag/AgCl electrode. The proposed electroanalytical method is operational in the linear working range from 3 to 100 μM of POA with a limit of detection of 1.37 μM. The developed analytical procedure was successfully tested for determination of this herbicide in standard/spiked river water samples and commercial herbicide Successor T SE/spiked river water samples, offering a simple, fast and inexpensive alternative way of pesticide determining to chromatographic methods employed for this purpose.

AB  - The electrochemical behavior of four dialkyl esters (methyl, ethyl, n-propyl and n-butyl) of (S,S)-α,α ′-(1,2-ethanediyldiimino)- bis[cyclohexanepropanoic acid] with moderate antitumor activity has been studied by cyclic voltammetry. I-E curves recorded at boron-doped diamond electrode in -2.00 < Ep < 0.00 V range show a single oxidative peak located in the -0.95 < Ep,a < -0.52 V region in a form of one-electron wave. The electrochemical processes appear to be irreversible for all compounds except for the compound with methyl substituent which demonstrates well-defined reversible electron transfer. Derivatives with bulkier moieties are easier to oxidize. For all investigated compounds an amine-centered redox process is dominant. Further investigation indicates that electrochemical reaction is diffusion controlled, chemically irreversible process. The results are discussed in terms of linking their electrochemical activity to antitumor effect. © 2018 The Electrochemical Society.

AB  - Redox properties of a set of aryldiketo acids (ADKs), small organic molecules that comprise 2,4-dioxobutanoic acid moiety, were studied. Along with well-known HIV-1 integrase (IN) inhibition, ADKs exert widespread biological activities. The aim of this work was to evaluate the effects of aryl substitutions on the properties of the dioxobutanoic moiety that is involved in key interactions with metal ions within the active sites of target enzymes. The effect of pH on the electronic properties of nine congeners was examined using cyclic voltammetry and differential pulse polarography. The compounds were chosen as a simple set of congeners bearing Me-groups on the phenyl ring, which should not be involved in electrochemical reactions, leaving the diketo moiety as the sole electrophore. The substitution pattern was systematically varied, yielding a set having different torsion between the phenyl ring and the aryl keto group (Ar-C(O)). The protonation state of the ADKs at different pH values was determined from the experimentally obtained pK(a) values. The results showed that an equal number of protons and electrons were involved in the oxidation and reduction reactions at the surface of the electrode. Quantitative linear correlations were found between the reduction potentials and the energies of the frontier orbitals, calculated for neutral, mono-anionic and the corresponding radical anionic species, and the steric parameter as two independent variables.

AB  - Propolis, as a beneficial natural product, has found application in the food and pharmaceutical industries as a food preservative, active packaging material as well as a main component of propolis containing products. Quality control of propolis has thus gained in importance. We used simple, fast, and low-cost techniques such as UV/Vis spectrophotometry and cyclic voltammetry applied in combination with principal component analysis to confirm the presence of two botanical sub-types of propolis. Cyclic voltammetry, as a green, sensitive, and convenient technique suitable for investigation of chemical profile, together with multivariate chemometrics technique, was used for the first time for characterization and classification of propolis. UV/Vis spectroscopy was applied in two aspects, absorption at certain wavelength for the quantitative determination of analytes, i.e. determination of quality control parameters, and spectral profiles, for the confirmation of the existence of two botanically different poplar types. All investigated Serbian propolis samples were characterized with specific chemical patterns and were classified in two main botanical varieties, so-called orange and blue. The results confirmed that the applied methods have a potential to be used for the discrimination of complex natural products such as propolis.
