AB  - In this work, the electrooxidation ability of nine pyridones was evaluated using cyclic(CV) and square-wave voltammetry (SWV) in Britton–Robinson (BR) aqueous buffer solutions on aglassy carbon electrode (GC). The dependence of electrochemical activity on pyridone structure waselucidated by means of experimentally obtained spectra and quantum chemical calculations. Firstly, itwas shown that electrochemical activity is determined by the –OH group as a substituent in position6 of the pyridone ring. By coupling the experimentally obtained UV-Vis spectra and DFT calculations,the most stable forms, both protonated and deprotonated, were defined. The calculated values areconsistent with the electrochemical behavior observed, indicating that the deprotonated anionic formwas the most electrochemically active. Moreover, the impact of the substituent in position 3 of thepyridone scaffold was discussed

AB  - Duloxetine hydrochloride (DUL) is effective in treating depression, and was examined for electroanalytical purposes. The DULstandard was investigated by cyclic voltammetry (CV) and determined using differential pulse voltammetry (DPV) via its electrooxidationat the Au electrode in 0.05 M NaHCO3. DPV showed a linear dependency of the anodic peak currents vs DUL standardconcentrations in the range from 0.1 to 3.33 μg ml−1 with the values of the limit of detection (LOD) and the limit of quantification(LOQ): 0.133 and 0.667 μg ml−1, respectively. Using the constructed and validated calibration curve, the values of unknown DULconcentrations in both Taita® tablets and in human serum spiked with the standard were determined. The number of protons andelectrons transferred was calculated and possible reaction mechanisms taking place on the surface of both electrodes wereproposed. The Au electrode exhibited a better sensitivity and a wider range of current vs concentration linear dependency for DULquantitative determination than the GC electrode. The study of DUL degradation showed that at the Au and GC electrodes, after4.5 h of potential cycling, degradation occurs, giving formaldehyde as a product, which was confirmed by high performance liquidchromatography (HPLC)

AB  - Ticagrelor hydrochloride (TCG) is effective in platelet inhibition and useful for preventing cardiovascular death, myocardial infarction, or ischaemic stroke. The drug standard was investigated by cyclic voltammetry (CV) and quantitatively determined using differential pulse voltammetry (DPV) via its electrooxidation at Au electrode in 0.05 M NaHCO3. DPV showed a linear dependency of the anodic peak currents vs. TCG standard concentrations in the range from 3 x 10-7 mol l-1 to 10-5 mol l-1 with the values of the limit of detection (LOD) and the limit of quantification: 0.288 μmol l-1 and 0.96 μmol l-1, respectively. Using the constructed and validated calibration curve, the values of unknown ticagrelor concentrations in Ticagrex® tablets and in human serum spiked with the standard were determined. Mechanistic study suggests that the oxidation proceeds at sulfur atom by removal of one electron as the rate determining step. In the next, fast step, formed radical cation loose another electron and sulfoxide is formed (with water molecule as nucleophile). The study of TCG degradation showed that at the Au, after 4.5 h of potential cycling, degradation occurs, which was confirmed by UV spectroscopy.

AB  - In this work, carbon paste electrode (CPE) and carbon paste electrode modified with gold nanoparticics (AuNPs/CPE) were employed with rapid direct anodic square wave voltammetry (SWV) for macrolide antibiotics erythromycin cthylsuccinate (EIS), azithromycin (A7.1), clarithromycin (OA) and roxithromycin (ROX) determination. The surface of working electrodes was morphologically characterized by scanning electron microscopic (SEM) measurements whereby the presence of randomly distributed AuNPs of 10 nm diameter size on CPE surface was confirmed by energy dispersive spectrometer (EDS). SWV determination of four macrolide antibiotics using CPE was performed in aqueous Britton-Robinson buffer solutions (pH 2.0 to 11.98) showing that oxidation signals strongly depend upon pH (at pH  gt = 6) and exhibited the most favorable characteristics at pH 8.0 in the case of EES and pH 11.98 in the case of AZI, CIA and ROX. Under optimized conditions, the SWV method using CPE enables determination of all investigated macrolide antibiotics in low mu g mL(-1) concentration ranges with relative standard deviations (RSDs) lower than 6% and achieved detection limits (1.0Ds) as 0.18, 0.045, 1.43 and 0.30 mu g mL(-1) for EES, AZI, CLA and ROX, respectively. In the case of AZ1 and ROX, it was demonstrated that the use of AuNPs/CPE as working electrode could additionally improve the results obtained with the SWV method concerning exhibited sensitivity, reproducibility and linear concentration range, due to the electrocatalytic properties of synthesized AuNPs. The optimized experimental parameters with the use of SWV method and CPF. or AuNPs/CPE were successfully applied for determination of ROX and AZI in their pharmaceutical preparations Runac (R) and Ilemomycine, respectively. The reliability of the elaborated procedures and thus the accuracy of the obtained results were validated by comparing them with those obtained by means of H PLC-DAD measurements.

AB  - The inclusion complexes of the selected, potentially biologically active, succinimides with beta-cyclodextrin (beta CD) and (2-hydroxypropyl)-beta-cyclodextrin (HP beta CD) were prepared. The formation of the inclusion complexes of the investigated monophenyl and diphenyl succinimide derivatives was confirmed using attenuated total reflection (ATR) study. Their electrochemical behavior was examined by cyclic voltammetry (CV) and square wave voltammetry (SWV) in 0.05 M NaHCO3 on a gold electrode. The stability constants for compound 1 were determined by cyclic voltammetry and calculated as K-beta CD = 350.87 M-1 and K-HP(beta CD) = 250.67 M-1. The SWV measurements reveal well defined peak at potential E-p = similar to 60 mV and the higher currents at E-p for both inclusion complex of the succinimides compared to the free compounds. The impact of chlorine atom in the phenyl moiety of succinimide derivatives on the activity in electro oxidation reaction is presented. Among the studied succinimides, according to SWV measurements, the most active is the monophenyl succinimide derivative (compound 1) in complex with beta CD. The difference of peak current of compound 1 + beta CD compared to compound 1 + HP beta CD and free compound is 6.3 and 35.2 mu A cm(-2), respectively.

The SWV measurements reveal well defined peak at potential E-p = similar to 60 mV and the higher currents at E-p for both inclusion complex of the succinimides compared to the free compounds. The impact of chlorine atom in the phenyl moiety of succinimide derivatives on the activity in electro oxidation reaction is presented. Among the studied succinimides, according to SWV measurements, the most active is the monophenyl succinimide derivative (compound 1) in complex with beta CD. The difference of peak current of compound 1 + beta CD compared to compound 1 + HP beta CD and free compound is 6.3 and 35.2 mu A cm(-2), respectively.",

AB  - In this study the electrochemical behavior of metformin (MET), oral antihyperglycaemic agent, was assayed at three different electrodes. The drug standard was investigated by cyclic voltammetry and square wave voltammetry via its electrooxidation at Au and glassy carbon electrode in 0.05 M NaHCO3. Under these conditions transformation of MET to corresponding N-carbonyl guanidine via oxime intermediate is suggested. The stability of MET was tested under directed stress conditions using IrOx electrode with sodium sulphate as an electrolyte and cyclic 4-amino-2-imino-1-methyl-1,2-dihydro-1,3,5-triazine appeared as the main end-product. The courses of the electrochemical processes at three electrodes were followed by UV spectroscopy and evaluated by total organic carbon analysis.

AB  - Esomeprazole is the most effective of the proton-pump inhibitors for the acid-related diseases and at first was examined for the electroanalytical purposes. The drug standard and as a content of injection powder was investigated by cyclic voltammetry (CV) and quantitatively determined using square wave voltammetry (SWV) via its electrooxidation at Au electrode in 0.05 M NaHCO3. SWV showed a linear dependency of the anodic peak currents vs. esomeprazole standard concentrations in the range from 3.0 to 500 mu g mL(-1) with the values of limit of detection (LOD) and limit of quantification (LOQ): 1.4 and 4.6 mu g mL(-1), respectively. Using the constructed and validated calibration curve, the values of unknown esomeprazole concentrations in injection powder and in human serum spiked with standard were determined. Before the electrochemical oxidation, it was shown by atomic force microscopy (AFM) that the small esomeprazole islands formed inside holes were visible and their diameter was about 200 nm attributed to physico-chemical characteristics of esomeprazole. After the electrochemical oxidation, the morphology of esomeprazole standard on Au surface was completely changed and composed of spherical particles in a diameter between 200 and 600 nm. With esomeprazole suspended in human serum, the process of crystallization partly occurred in the form of spherical grains with the average size of these grains was about 4 gm. The analysis at the macro level done by the optical microscopy (OM) confirmed this opinion. The study of esomeprazole degradation showed that at Au electrode, after 3 h of cycling, a neglectable amount of the esomeprazole was changed. Using IrOx electrode under directed stress conditions, its almost complete degradation was realized after 3 h confirmed by high performance liquid chromatography (HPLC). Total organic carbon (TOC) analysis showed that 95% of esomeprazole was mineralized. The HPLC and Liquid chromatography-mass spectrometry (LC-MS) study revealed the formation of 4-hydroxy omeprazole sulphide, 4-hydroxy omeprazole sulphone, esomeprazole sulphone and methylated esomeprazole.

AB  - A series of succinimide derivatives were studied using the cyclic and square wave voltammetry. Density function theory was used in order to determinate which of the structural parameters influence the electrochemical activity. The quantum chemical calculations of the investigated succinimides were linked with the experimental electrochemical data and used to propose the oxidation mechanism. The most active among studied succinimides is 1,3-diphenylsuccinimide. The results obtained from the cyclic and square wave voltammetry and quantum chemical calculations indicate that the investigated compounds undergo oxidation by irreversible, diffusion controlled process including transfer of 1e(-) and 1 proton. The voltammetric and DFT results signify that the mechanism of electrochemical oxidation of all compounds involve the conversion of carbonyl-methyne-phenyl segment or methylene group in free radical. This conversion proceeds by the loss of one proton one electron process.

AB  - Esomeprazole has been shown to be the most effective oral PPI for controlling intragastric pH. The persistence of esomeprasole in environmental systems could be solved by different types of its degradation. In this work electrocatalytic degradation of esomeprasole has been investigated in the presence of sodium sulfate and sodium chloride using IrOx electrode and was monitored using UV-Vis spectrophotometer at 303 nm.

AB  - Glucose biosensor containing cysteine (Cys), glutaraldehyde (GA) and glucose oxidase (GOx) onto gold electrode is constructed and already electrochemically tested. Now, the electrochemical behavior of biosensor in human serum is further investigated and supported by morphological characterization of layers for the first time. The morphology and microstructure of layers was examined by Fourier transformed infra red spectroscopy (FTIR), atomic force (AFM) and optical microscopy (OM). The electrochemical indication that the Cys-GA-GOx film on Au surface is not compact and that there were some bare regions which remain catalytically active is supported by AFM and OM results. The construction and the nature of bonding of Au-Cys-GA-GOx biosensor layers is confirmed by the FTIR study.

AB  - Electrochemical behavior of sildenafil citrate (SC) at gold and cystein (Cys) modified gold electrode (AulCys) in 0.1 M H2SO4 was investigated by cyclic voltammetry (CV) and by square wave voltammetry (SWV). Effect of scan rate on the CVs of SC standard was performed in order to examine the mode of transport and irreversibility of process. SC as standard is determined by SWV in acid solution at Au electrode in a range: 10(-3), 10(-2) 0.1, 0.5, 1 mu M and on Au/Cys in a range: 10(-3), 10(-2) 0.05, 0.1 mu M. The presence of Cys causes two-time larger peak currents and shifting of the incipient potential of the SC oxidation to 0.1 V in negative direction. In investigated range of concentration of SC standard in acid solution on modified and unmodified Au electrodes SWV method have excellent linear regression coefficient with value 0.997 promoting SWV for reliable determination of SC.

AB  - The method to develop a stable glucose biosensor with successive attachment of cysteine (Cys), glutaraldehyde (GA) and glucose oxidase (GOx) onto gold electrode is presented. The cyclic voltammetry (CV) suggests the diffusion control of the glucose oxidation. The obtained biosensor shows a fast electron transfer of k(0) = 20.4 s(-1), high affinity for glucose with the apparent MichaelisMenten constant K-M(app) = 1.15 mM, a low detection limit of 0.94 mM in a linear range 1.5-7 mM. This biosensor exhibits good stability and reproducibility. Good biocompatibility of modified electrode surface, which enhances the covalent bonded enzyme and consequently glucose oxidation, resulted in biosensor with excellent performances.

AB  - The electrodegradation of azithromycin was studied by its indirect oxidation using dimensionally stable Ti/RuO2 anode as catalyst in the electrolyte containing methanol, 0.05 M NaHCO3, sodium chloride and deionized water. The optimal conditions for galvanostatic electrodegradation for the azithromycin concentration of 0.472 mg cm(-3) were found to be NaCl concentration of 7 mg cm(-3) and the applied current of 300 mA. The differential pulse voltammetry using glassy carbon electrode was performed for the first time in the above-mentioned content of electrolyte for the nine concentration of azithromycin (0.075-0.675 mg cm(-3)) giving the limits of azithromycin detection and of quantification as: LOD 0.044 mg cm(-3) and LOQ 0.145 mg cm(-3). The calibration curve was constructed enabling the electrolyte analysis during its electrodegradation process. The electrolyte was analyzed by high-performance liquid chromatography and electrospray ionization time-of-flight mass spectrometry. The electrooxidation products were identified and after 180 min there was no azithromycin in the electrolyte while TOC analysis showed that 79% of azithromycin was mineralized. The proposed degradation scheme is presented.

AB  - The renewable silver-amalgam film electrode (Hg(Ag)FE) was applied for voltammetric characterization and determination of semi-synthetic macrolide antibiotics azithromycin (AZI), clarithromycin (CLA) and roxithromycin (ROX) in the Britton-Robinson buffer as supporting electrolyte ranging the pH from 4.0 to 11.9. All three macrolides showed reduction signals in fairly negative potential range. During direct cathodic square wave voltammetric (SWV) investigations conducted over the potential range from -0.75 V to -2.00V vs SCE, either one or two reduction peaks were obtained in the potential range from -1.5 to -1.9 V. The shapes and intensities of the signals depend on the applied pH values in wider pH ranges. For analytical purposes concerning the development of direct cathodic SWV and adsorptive stripping SWV (SW-AdSV) methods the neutral and slightly alkaline media were suitable as pH 7.2, pH 7.4 and pH 7.0 for AZI, CIA and ROX, respectively. Based on the cyclic voltammograms recorded at these pH values, adsorption-controlled electrode kinetics process can be proposed for all three macrolides. Furthermore, the water suppressed H-1 NMR measurements in the pH range between 6.0 and 10.5 indicated that the macrolide molecules at the optimal analytical conditions are predominantly in protonated form via their tertiary amino groups which supported in all three cases their adsorption on the appropriately polarized Hg(Ag)FE electrode. The optimized direct cathodic SWV methods showed good linearity in concentration ranges 4.81-23.3 mu gmL(-1), 1.96-28.6 mu gmL(-1) and 1.48-25.9 mu gmL(-1) for AZI, CIA and ROX, respectively. The development of the SW-AdSV methods resulted in the linear responses at lower concentration ranges as 1.0-2.46 mu gmL(-1), 0.05-0.99 mu gmL(-1) and 0.10-0.99 mu gmL(-1), for AZI, CIA and ROX, respectively. The relative standard deviation for all developed methods was not higher than 1.0% except the SWV method for AZI with 4.7%. In the case of all three investigated macrolide antibiotics the protonated form of the tertiary amino group(s) at appropriate accumulation potential and time favored the adsorption of the ionic form of the target molecules offering the opportunity for the development of SW-AdSV methods for their trace level analysis on Hg(Ag)FE. Optimized SW-AdSV method was applied for determination of ROX in pharmaceutical preparation Runac.

AB  - The electrochemical behavior of phenobarbital sodium (PBS), paracetamol (PCM) and their binary mixtures was investigated using cyclic voltammetry (CV) and square wave voltammetry (SWV) at a bare gold electrode in a 0.05 M bicarbonate solution. A calibration curve of PBS obtained by SWV had two linear ranges, from 1.0 to 3.0 mu M and from 5.0 to 35.0 mu M with a limit of quantification (LOQ) of 0.62 mu M and a limit of detection (LOD) of 0.19 mu M, while a calibration curve of PCM was determined within the range from 10.0 to 50.0 mu M with a LOQ of 8.53 mu M and a LOD of 2.56 mu M. Both drugs underwent oxidation by irreversible, diffusion controlled process. The SW voltammograms of the drug mixtures produced complex, overlapping profiles and a chemometric method was applied for their decomposition. Two different artificial neural network (ANN) architectures, namely back-propagation neural network (BPNN) and general regression neural network (GRNN) were employed for the simultaneous prediction of the concentrations of the drugs in a synthetic sample. The BPNN model had higher accuracy (mean absolute percentage error values were in the range of 3.6-8.4%) and thus it can be used for the simultaneous determination of PBS and PCM.

AB  - Electrochemistry is rapidly growing area with a number of possible applications in the pharmaceutical analysis. Modern electrochemical methods are selective, sensitive, rapid, and provide easy techniques applicable to analyses in the pharmaceutical fi eld. It is evident that the electroanalytical techniques at varying levels of sensitivity are required to solve analytical–pharmaceutical problems. The advantages of electrochemical methods are the simple procedures of the sample preparation and in most cases lack of interferences from excipients in the pharmaceutical dosage forms.

It is evident that the electroanalytical techniques at varying levels of sensitivity are required to solve analytical–pharmaceutical problems. The advantages of electrochemical methods are the simple procedures of the sample preparation and in most cases lack of interferences from excipients in the pharmaceutical dosage forms.",

AB  - Tebuconazole, a pesticide that presents risks for ecosystems, groundwater and human health, was degraded on a gold electrode as the catalyst in 0.05 M NaHCO3 using cyclic voltammetry (CV). First, tebuconazole was characterized on the gold electrode using CV and square wave voltammetry (SWV). The gold electrode, being highly sensitive, provided linear relationships (currents vs. concentrations) in the range: (0.076-0.76 mu mol dm(-3)). Based on the CV measurements, the investigated process is irreversible and diffusion controlled. The observed catalytic role of the Au electrode in the oxidation of tebuconazole and the data obtained from CV and SWV provided the experimental conditions for the degradation of tebuconazole. The degradation was performed by continuous cycling followed by gas chromatography mass spectroscopy (GC MS) analysis. This enabled the catalytic elimination of tebuconazole for 60 min, which promoted the use of a gold electrode as the catalyst for the degradation of environmental pollutants. The scheme of the possible mechanism of tebuconazole degradation is given.

AB  - Nonmedical use of sildenafil citrate (SC) requires new methods for drug determination in human serum and in tablets. SC as standard and in Sildena (R) tablets is determined by square wave voltammetry (SWV) in 0.1 M H2SO4 (harmful for human serum) at gold electrode in a range: (1 x 10(-3),1 x 10(-2), 0.1, 0.5,1) mu M and on cysteine (Cys) modified gold electrode (Au/Cys) in a range: (1 x 10(-3),1 x 10(-2), 0.05, 0.1) mu M. The presence of Cys causes two times larger peak currents and shifting of the incipient potential of the SC oxidation to 0.1 V in negative direction. A safe procedure for SC determination as standard and in Sildena (R) tablets spiked with human serum is developed by SWV at gold electrode in 0.05 M NaHCO3 (suitable for human liquids) in a range: (1 x 10(-3),1 x 10(-2), 0.1, 0.2, 03) mu M. Microscopic characterization of the surfaces morphology was also performed. The SC concentrations were checked by high performance liquid chromatography-ultraviolet spectroscopy (HPLC-UV) showing that electrochemical method is more sensitive and can be used for the measurements of very low concentrations of the analyte.

AB  - Erythromycin, a macrolide antibiotic, has similar antimicrobial spectrum to penicillin and it is widely used, especially in the treatment of patients who are allergic to penicillin. In this work, the application of a renewable silver-amalgam film electrode (Hg(Ag)FE) for the characterization and determination of erythromycin ethylsuccinate (EES), a widely used esterified form of this antibiotic, by means of cyclic voltammetry (CV) and square wave voltammetry (SWV) is presented. In the aqueous Britton-Robinson buffer (pH 5.0-9.0) that served as the supporting electrolyte, one reduction peak of EES was observed in the investigated potential range between -0.75 V and -1.80 V vs SCE, with peak potential maxima ranging from -1.59 V to -1.70 V, which strongly depended on the applied pH, as did the peak shape. For the analytical purposes the pH of 7.0 was selected, since in this electrolyte the EES peak was well-shaped and separated from the background current of the supporting electrolyte in both cases; in the direct cathodic SWV and in the case of square wave adsorptive stripping voltammetry (SW-AdSV). It was established, by the E-p-pH correlation, that protons strongly influenced the electrochemical reduction of EES. The CVs recorded between 0.025-0.50 V s (1) at pH 7.0 confirmed that the electrode reaction is adsorption-controlled. Based on the series of H-1 NMR measurements it is proved that the tertiary amino group of EES is mainly in its protonated form at pH 7.0 which may lead, at appropriate accumulation potential and time, to the favored adsorption of the target ionic form of the analyte improving on such way the sensitivity of the SW-AdSV method. The optimized procedures resulted in stable SWV responses with good linear correlation in the EES concentration range from 4.53 to 29.8 mu g mL (1) (LOD = 1.36 mu g mL (1)), and from 0.69 mu g mL (1) to 2.44 mu g mL (1) (LOD 0.21 mu g mL (1)) in the case of optimized SW-AdSV. The relative standard deviation is below 1.5%. The reliability of the elaborated procedures and thus the accuracy of the obtained results were validated by comparing them with those obtained by means of HPLC-DAD measurements. The direct cathodic SWV method was successfully applied for the determination of EES in the pharmaceutical preparation Eritromicin (R), while SW-AdSV was applied in the case of the spiked urine sample. In both cases, the standard addition method was used.

AB  - Anisomycin is an immunosuppressant in low doses ( lt 0.1 mu M) with possible application in treatment of some autoimmune diseases and in inhibiting transplantation rejection. Anisomycin suppresses malignant tumor cell growth and affects memory. For the first time it was the subject of the electrochemical investigations by cyclic voltammetry and square wave voltammetry on gold electrode in 0.05 M NaHCO3 using its electrochemical activity. The cyclic voltammetry experiments at different sweep rates show that electrochemical process is irreversible and diffusion controlled. Based on square wave voltammetry measurements, the calculated values of LOD and LOQ were 1 and 4 nM (in the absence of biological fluid), as well as 2 and 6 nM (in the presence of spiked urine) indicating the high sensitivity of the proposed electroanalytical method. High performance liquid chromatography-tandem mass spectrometry was a reference method for quantification of anisomycin and served for structural identification of its hydrolysis product (deacetylanisomycin).

AB  - Phenytoin (5,5-diphenylhydantoin), one of the most frequently used anticonvulsant and antiarrhythmic drugs, was examined and determined at bare gold electrode in 0.05 M NaHCO3 using its anodic activity by cyclic voltammetry (CV) and square wave voltammetry (SWV). Gold electrode is highly sensitive to the phenytoin concentration (the investigated level of concentrations is usually found in human serum of patients treated with phenytoin), providing linear relationships for a set of lower concentrations (0.5, 0.6, 0.8, 1.0 mu mol dm(-3)) and for a set of higher concentrations (10, 20, 30, 40, 50 mu mol dm(-3)). The effects of the substituent on the phenyl rings on the electrochemical behavior of two derivatives, 5,5-di(4-chlorophenyl) hydantoin and 5,5-di(4-methylphenyl) hydantoin, were examined by CV. A computational study in correlation with the experimental voltammetric results enabled to propose the oxidation mechanisms: the investigated compounds undergo oxidation involving transfer of 1e(-) and 1 proton by irreversible, diffusion controlled process.

AB  - This study describes the investigation of degradation products of donepezil (DP) using a stability-indicating RP-HPLC method for determination of donepezil, which is a centrally acting reversible acetyl cholinesterase inhibitor. In order to investigate the stability of the drug and formed degradation products, a forced degradation study of the drug sample and finished product under different forced degradation conditions was conducted. Donepezil hydrochloride and donepezil tablets were subjected to stress degradation conditions recommended by the International Conference on Harmonization (ICH). Donepezil hydrochloride solutions were subjected to acid and alkali hydrolysis, chemical oxidation and thermal degradation. Significant degradation was observed under alkali hydrolysis and oxidative degradation conditions. Additional degradation products were observed under the conditions of oxidative degradation. The degradation products observed during forced degradation studies were monitored using the developed high performance liquid chromatography (HPLC) method. The parent method was modified in order to obtain LC-MS compatible method, which was used to identify the degradation products from forced degradation samples using high resolution mass spectrometry. The mass spectrum provided the precise mass from which the molecular formula of the drug substance and formed degradation products was derived, and proved the specificity of the method unambiguously.
AB  - Proučavanje degradacionih proizvoda donepezila je izvršeno korišćenjem RP-HPLC metode za određivanje stabilnosti donepezila, leka koji pripada grupi reverzibilnih inhibitora acetilholinesteraze. U cilju ispitivanja stabilnosti leka i njegovih degradacionih proizvoda sprovedena je studija forsirane degradacije čiste supstance kao i farmaceutskog proizvoda pod različitim uslovima. Donepezil-hidrohlorid i donepezil tablete su podvrgnuti različitim uslovima degradacije prema preporukama Internacionalne konferencije za harmonizaciju. Rastvori donepezil-hidrohlorida su podvrgnuti kiseloj i baznoj hidrolizi, hemijskoj oksidaciji i termalnoj degradaciji. Pri baznoj hidrolizi i hemijskoj oksidaciji uočena je značajna degradacija polaznog molekula. Oksidativnom degradacijom nastaju i proizvodi koji nisu uočeni kod ostalih postupaka forsirane degradacije. Nastali proizvodi analizirani su novorazvijenom HPLC metodom. Osnovna metoda je modifikovana u cilju dobijanja LC-MS kompatibilne metode kako bi se identifikovali nastali degradacioni proizvodi. Na osnovu resultata dobijenih masenom spektrometrijom dobijene su tačne mase proizvoda degradacije, čime je omogućeno određivanje njihovih molekulskih formula.

AB  - Covalent sidewall functionalization of multiwalled carbon nanotubes (MWCNTs) has been performed using two approaches, direct and indirect cycloaddition through diethyl malonate, based on the Bingel reaction. The results revealed that functionalized MWCNTs demonstrated enhanced electrical properties and significantly lower sheet resistance, especially after electric field thermal assisted annealing at 80 degrees C was performed. The presence of 1,3-dicarbonyl compounds caused the surface of MWCNTs to be more hydrophilic, approachable for the electrolyte and improved the capacitance performance of Au/MWCNTs electrodes. The modified MWCNTs have been incorporated into nanocomposites by using solution mixing method with polyaniline and drop-casting resulting mixture on the paper substrate. The reduction in the sheet resistance with increasing the content of MWCNTs in the prepared nanocomposite films has been achieved.

AB  - The electrochemical behavior of six arylazo pyridone dyes classified to the substituents present at the phenylazo and 2-pyridone moiety and their 1:1 inclusion complexes with (2-hydroxypropyl)-beta-cyclodextrin was studied using cyclic and square wave voltammetry in 0.1 M NaOH on a gold electrode. The formation of the inclusion complexes of the dyes was confirmed using UV-Vis and FTIR spectroscopy measurements. Among the studied dyes, according to potentiodynamic measurements, the most active is the dye 1. The inclusion complexes of the dyes exhibited improved electrochemical activity in comparison to the pure dyes. The results obtained by square wave voltammetry show the apparent activity of the dyes with a methoxy group as a substituent at the phenylazo moiety and ethyl and hydroxyethyl groups in the 2-pyridone moiety, and their inclusion complexes. The electrooxidation mechanism of the investigated arylazo pyridone dyes was also proposed.
