AB  - The structure of the newly synthesized coumarin derivative, 3-(1-(3-hydroxypropylamino)-ethylidene)-chroman-2,4-dione, was investigated theoretically. The density functional theory calculations, with B3LYP functional (and with empirical dispersion corrections D3BJ) in combination with the 6–311+G(d,p) basis set, are performed in order to optimized the molecular structure of the investigated coumarin derivative. Molecular docking analysis was carried out in order to identify the potency of inhibition of the title molecule against human C-reactive protein. The inhibition activity was obtained for ten conformations of ligand inside protein.
AB  - Struktura novo sintetisanog derivata kumarina, 3- (1- (3-hidroksipropilamino) -etiliden) -hroman-2,4-diona, ispitana je primenom teorijskih metoda. Za optimizaciju strukture ispitivanog kumarinskog derivata korišćena je teorija funkcionalne gustine: B3LYP funkcional ( sa empirijskim ispravkama disperzije D3BJ) u kombinaciji sa 6-311+G(d, p) bazisnim setom. Urađen je molekulski doking, kao i analiza dobijenih rezultata kako bi se utvrdio potencijal inhibicije molekula ispitivanog jedinjenja prema humanom C-reaktivnom proteinu. Aktivnost inhibicije izračunata je za deset potencijalnih konformacija liganda unutar proteina.

AB  - In this paper was investigated the antioxidative activity of alizarin-2-glycoside. All results were obtained using the DFT method. For calculations, the M06-2X method was used in combination with the 6-311++G(d,p) base set. Water was used as a solvent. The values of enthalpy were used as thermodynamic parameters on the basis of which the antioxidative capacity of alizarin-2-glycoside was evaluated. The Molecular Docking method was used for assessing the ability of alizarin-2-glycoside to inhibit the negative effect of P-glycoprotein.

AB  - Proposed distributed reactivity model of dehydration for seedling parts of two various maize hybrids (ZP434, ZP704) was established. Dehydration stresses were induced thermally, which is also accompanied by response of hybrids to heat stress. It was found that an increased value of activation energy counterparts within radicle dehydration of ZP434, with a high concentration of 24-epibrassinolide (24-EBL) at elevated operating temperatures, probably causes activation of diffusion mechanisms in cutin network and may increases likelihood of formation of free volumes, large enough to accommodate diffusing molecule. Many small random effects were detected and can be correlated with micro-disturbing in a space filled with water caused by thermal gradients, increasing capillary phenomena, and which can induce thermo-capillary migration. The influence of seedling content of various sugars and minerals on dehydration was also examined. Estimated distributed reactivity models indicate a dependence of reactivity on structural arrangements, due to present interactions between water molecules and chemical species within the plant.

AB  - The UV-Vis properties of ten Schiff bases were systematically investigated. The time-dependent density functional theory (TDDFT) approach in combination with the B3LYP functional was used for simulation of UV-Vis spectra of examined compounds. The shapes of the Kohn-Sham molecular orbitals involved in electronic transitions were misleading. To provide better understanding of distribution of electron density natural bond orbital (NBO) analysis was used. NLMO clusters were constructed and they represent a part of a molecule characterized with eminent electron density. The TDDFT and NBO theories are complementary, and the results from these two approaches are combined to interpret the UV-Vis spectra.

AB  - Cyanidin, as one important plant pigment, was theoretically (at M05-2X/6-311+G(d,p) level of theory) investigated for its ability to scavenge potentially, highly damaging hydroxyl radical. Free radical scavenging of cyanidin was studied through electron transfer mechanism – ET (the second step in SPLET mechanism) in water and ethanol, as solvents. Examination was performed using density functional theory (DFT) and Marcus theory. Based on the thermochemical and kinetic data, it is clear that O‒H group of cyanidin in position 3` is the most suitable for reaction with hydroxyl radical through mentioned antioxidant mechanism.

AB  - Different metabolic processes as nus products form variety free radicals. Those radicals have damaging influence to people health, when they are formed in human bodies, or react as active components in reactions of nutrients decay. In this article are investigated mechanisms of radical scavenging activity of alizarin in reactions with •OH, •OOH and CH3OO• radicals. All results are obtained using DFT method. For calculations is used M06-2X functional in combination with 6-311++G(d,p) basis set. Lipid and aqueous environment are imitated. All conclusions are based on ΔH values, as thermodynamically indicator for anticipation of reaction pathway.

AB  - Thermal stability of a series of palladium(II) complexes with N-heteroaromatic bidentate hydrazone ligands was investigated using a combination of experimental measurements and DFT calculations. All complexes exhibit a reversible second-order transition around 333 K, which can be attributed to structural reorganization of the ligand molecules. Thermal degradation begins in 570-610 K temperature region, with an endothermic peak, followed by exothermic peaks in DSC. TG measurements show a well-defined mass loss corresponding to the initial degradation, while subsequent processes are poorly separated. DFT calculations suggest that the initial degradation step occurs with release of Cl, which then reacts with remaining part of the complex molecule in an exothermic process. This leads to decomposition of the ligand molecule into four fragments corresponding to ethyl chloride, carbon dioxide, methyl amine, and the fragment with the aromatic group. Mass spectrum suggests that creation of these fragments most likely corresponds to the initial degradation, after which some of these coordinate to Pd center, whose coordination sphere is left incomplete by release of Cl. TG measurement to 1123 K indicates that the final degradation product at this temperature is palladium.

AB  - Density functional theory calculations were performed to evaluate the antioxidant activity of alizarin red S molecule. The conformational behavior of molecule were analysed at the M06-2X/6-311++G(d,p) method. The most stable conformer of alizarin red S has two IHBs. The expected antioxidant activity of alizarin red S was justified from ionization potential (IPs) and homolytic O-H bond dissociation enthalpy (BDEs) values. Heterolytic O-H bond cleavages (proton dissociation enthalpies, PDEs) were also computed. Calculated IP, BDE, and PA values suggested that one-step H atom transfer (HAT), rather than SPLET or SET-PT, would be the most favored mechanism for explaining the antioxidant activity of alizarin red S in gas phase. In aqueous solution all of three mechanisms were competitive.
AB  - Upotrebom DFT metode vršena su izračunavanja u cilju određivanja antioksidativne aktivnosti alizarina red S. Konformaciona priroda molekula analizirana ispitana je primenom M06-2X/6-311++G(d,p) metoda. Najstabilniji konformer alizarina red S ima dve unutrašnje vodonične veze. Očekivana antioksidativna aktivnost alizarina red S određena je izračunavanjem vrednosti jonizacionih potencijala (IP) i i vrednosti entalpija homolitičkog raskidanja O-H veza (BDE). Vrednosti entalpije heterolitičkog raskidanja O-H veza (entalpije disocijacije protona, PDE), su takođe izračunate. Izračunate IP, BDE i PA vrednosti ukazuju na to da je jednostepeni transfer H-atoma (HAT), pre nego SPLET ili SET-PT mehanizam, favorizovan u pogledu antioksidativne aktivnosti alizarina red S u gasnoj fazi. U vodenom rastvoru, sva tri mehanizma su konkurentna.

Konformaciona priroda molekula analizirana ispitana je primenom M06-2X/6-311++G(d,p) metoda. Najstabilniji konformer alizarina red S ima dve unutrašnje vodonične veze. Očekivana antioksidativna aktivnost alizarina red S određena je izračunavanjem vrednosti jonizacionih potencijala (IP) i i vrednosti entalpija homolitičkog raskidanja O-H veza (BDE). Vrednosti entalpije heterolitičkog raskidanja O-H veza (entalpije disocijacije protona, PDE), su takođe izračunate. Izračunate IP, BDE i PA vrednosti ukazuju na to da je jednostepeni transfer H-atoma (HAT), pre nego SPLET ili SET-PT mehanizam, favorizovan u pogledu antioksidativne aktivnosti alizarina red S u gasnoj fazi. U vodenom rastvoru, sva tri mehanizma su konkurentna.",

AB  - In this paper are investigated the ΔHBDE, ΔHIP, and ΔHPA values of the corresponding reactions in the solvents of different polarity (water and pentylethanoate). An approach based on the enthalpies of the reactions related to the HAT, SPLET, and SET-PT mechanisms of gallic acid with some radicals (•OO-, •OH, and CH3OO•) is applied. The results show that thermodynamically favored mechanism depends on the polarity of reaction media and properties of free radical reactive species.
AB  - U ovom radu su ispitivane ΔHBDE, ΔHIP, i ΔHPA vrednosti odgovarajućih reakcija u rastvaračima različite (voda i pentiletanoat). Primenjen je pristup zasnovan na entalpijama reakcija povezanih sa HAT, SPLET, i SET-PT mehanizmima galne kiseline sa određenim radikalima (•OO-, •OH, i CH3OO•). Rezultati pokazuju da termodinamički favorizovan mehanizam zavisi od polarnosti rastvarača u kome se reakcija odvija i osobina slobodno radikalske vrste koja reaguje.

AB  - In this paper antioxidative mechanisms HAT, SPLET and SET-PT of the carboxylate anion of gallic acid (GA¯) with different radicals (OO−, OH, and CH3OO) were investigated. For this reason were examined ΔHBDE, ΔHIP and ΔHPA values of the corresponding reactions in water and pentyl ethanoate as solvents. For this purpose the M052X/6-311++G(d,p) theoretical models was applied. It was found that SET-PT is not favorable reaction path for all anions of GA (GA¯) in both solvents. On the other hand, HAT and SPLET mechanisms are competitive in all cases. Which of mentioned reaction path is predominant depends on the properties of anions, radicals and solvents.
AB  - U ovom radu su ispitani HAT, SPLET i SET-PT mehanizmi antioksidativnog delovanja karboksilatnog anjona galne kiseline (GA¯) sa različitim radikalima (OO−, OH i CH3OO). U tom cilju ispitane su ΔHBDE, ΔHIP i ΔHPA vrednosti odgovarajućih reakcija u vodi i pentiletanoatu kao rastvaračima. Za to je korišćen M052X/6- 311++G(d,p) teorijski model. Nađeno je da SET-PT mehanizam nije povoljan reakcioni put niti za jedan anjon galne kiseline (GA¯) u oba rastvarača. S druge strane, HAT i SPLET mehanizmi su konkurentni u svim slučajevima. Koji od reakcionih puteva je predominantan zavisi od osobina anjona, radikala i rastvarača.
