AB  - Fluorination of compounds causes an increase in the proton-donating ability and a decrease in the proton-accepting capacity of groups in their vicinity. The formation of F···F interactions is followed by the shift of the electron density in the area of F···F contact, which creates a new region with a larger surface area, a higher negative potential, and, hence, a more pronounced accepting ability. The new region also has a greater ability to form multiple (simultaneous) interactions with species from the environment, thus compensating for the reduction of the accepting capacity of the groups in the vicinity. This phenomenon explains not only the abundance of F···F interactions in crystal structures, but also a large number of structures with F···O interactions. Only C–H···F interactions are more numerous than F···F interactions in crystal structures, which indicates a high affinity of fluorinated compounds for nonpolar groups.

AB  - The molecular properties of the environmental mutagens nitrofluoranthenes (NFs; 1-, 2-, 3-, 7- and 8-NF), such as (hyper)polarizability, dipole moment, molecular electrostatic potential (MEP), spectroscopic characteristics, magnetic index (NICS) and others, obtained by means of ab initio (MP2) and density functional theory (DFT) approaches have been correlated with the observed mutagenic activities. A very good linear correlation (Rav = 0.99) between average polarizability () and experimental mutagenic activities of NFs in different Salmonella typhimurium strains from two independent experimental studies (Vance and Levin, Environ. Mutagen. 6 (1984) 797 and Zielinska et al., Mutation Res. 206 (1988) 131) was established. Higher values of polarizability derivatives with respect to the νsNO+CN vibrational coordinate for 8-NF and 3-NF compared to 1-NF and 7-NF and, consequently, higher Raman activities in the spectra that are in correlation with mutagenic activities, implicate significant intermolecular interactions along this vibrational coordinate. The results indicate that the binding of NFs to enzymes is the main step in mutagenic pathway of these nitro derivatives.
AB  - Молекулске особине мутагена нитрофлуорантена (NF; 1-, 2-, 3-, 7- и 8-NF) као што су (хипер)поларизабилност, диполни момент, молекулски електростатички потенцијал (MEP), спектроскопске карактеристике, магнетни индекс (NICS) и др., добијене ab initio (MP2) и DFT приступом, корелисане су са мутагеним активностима ових изомера. Установљена је врло добра линерана корелација (Rav = 0,99) између средње поларизабилности () и експериментално одређених мутагених активности нитрофлуoрантена у различитим сојевима бактерије Salmonella typhimurium из две независне експерименталне студије (Vance and Levin, Environ. Mutagen. 6 (1984) 797 и Zielinska et al., Mutation Res. 206 (1988) 131). Веће вредности извода поларизабилности у односу на νsNO+CN вибрациону координату за 8-NF и 3-NF у поређењу са 1-NF и 7-NF и, следствено томе, веће вредности Раман активности у спектрима које су у корелацији са мутагеном активношћу, упућују на знатне молекулске интеракције дуж ове вибрационе координате. Резултати указују да је везивање изомера NF за активно место ензима главни корак у активацији мутагености код ових нитро деривата.

AB  - Novel succinimide derivatives were synthesized from 3-methyl-3-phenylsuccinic acid and substituted anilines under solvent-free conditions by using microwave irradiation. All obtained compounds were characterized by ultraviolet (UV), Fourier-transform infrared (FT-IR), 1H and 13С nuclear magnetic resonance (NMR) spectroscopy as well as by elemental analysis. The influence of the substituent electronic effects on spectroscopic data was analyzed by applying the Hammett equation. Moreover, a detailed interpretation and comparison of experimentally obtained and theoretically calculated FT-IR, UV and NMR spectra was performed. Density functional theory (DFT) calculated data of the investigated succinimides were obtained and analyzed in order to determine their structural, spectroscopic and electronic properties. Furthermore, ADMET factor profiling and in-silico prediction of potential biological activities of novel succinimide derivatives have been performed.

Uticaj elektronskih efekata supstituenata na spektroskopske podatke analiziran je upotrebom Hametove jednačine. Takođe, izvršena je detaljna interpretacija, kao i poređenje eksperimentalno dobijenih i teorijski izračunatih FT-IR, UV i NMR spektara.

AB  - The binding of hydrogen sulfide to a model heme compound is investigated by coupled-cluster singles-doubles augmented by a perturbative triple excitations, CCSD(T), and density functional theory, DFT. The minimum energy path for the H2S addition to an isolated heme center of the heme protein is evaluated by adopting as a model the heme compound FeP(Im) (P = porphyrin; Im = imidazole). The FeP(Im)-H2S aduct is bound by 13.7 kcal/mol at the CCSD(T) level of theory. Relaxed potential energy curves for the lowest lying spin states of the H2S to FeP(Im) binding using DFT reveal that the binding process is associated with a "double spin-cross-over" reaction with the existence of long-distance van der Waals minima only 5-7 kcal/mol above the FeP(Im)-H2S ground state. The fact that the energy of the singlet ground state of FeP(Im)-H2S is so close in energy to the dissociation products FeP(Im) + H2S points towards the reversibility of the H2S adsorption/desorption process in biochemical reactions.

AB  - Statistical analysis of data extracted from the Cambridge Structural Database (CSD) has been used to investigate the crystal structure properties of odialkoxybenzene derivatives, compounds containing two ether oxygen acceptors in ortho positions of benzene ring. It has been shown that in more than 90% of cases, the fragment has predictable geometrical characteristics where the two ether oxygens form short interatomic O center dot center dot center dot O contact (2.57 A in average), while O-substitutents take trans position, both approximately coplanar with the benzene ring. Such arrangement of oxygen acceptors produces a large and uniform area of the negative electrostatic potential suitable for multiple hydrogen bonding. The acceptor abilities of the O center dot center dot center dot O system have been investigated by the statistical CSD analysis. The ab initio estimation of the interaction energy in the dimer of o-dimethoxybenzene (DMB) and H2O, employed as a model system, is achieved via high-level electron correlation CCSD(T) calculation with the complete basis set extrapolation. The interaction energy is estimated to be 6.5 kcal/mol. The results indicate the existence of a very flat potential the region between methoxy oxygens and that DMB water is a highly flexible system. The structural role of the O center dot center dot center dot O acceptor system is particularly interesting considering its ability to form multiple hydrogen bonding

AB  - This manuscript gives a summary of photoinduced processes in several Nitropolycyclic Aromatic Hydrocarbons (NPAHs) (nitronaphthalene, nitrofluorene, nitroanthracene, and nitropyrene) as well as the results of the TD-DFT calculations of the excited states and the geometries in the ground and first singlet excited electronic states of three isomers of nitrophenanthrene (1NPh, 3NPh, and 9NPh) which are presented for the first time. The decay of the first excited singlet state can lead to different pathways depending on a variety of factors: the energy gap between the S-1 state and the nearest state from the triplet manifold, geometries of the electronic states, electronic configuration of the states, etc. The gas phase NPAH molecule can bind to particulate matter in the atmosphere and different solvents present in the aerosol can activate or inhibit photoprocesses. These events depend strongly on the solvent polarity. We reviewed experimental studies that explored these variations of photoinduced processes in conjuction with TD-DFT and ab initio computations.

AB  - The binding of hydrogen sulfide to a model heme compound is investigated by coupled-cluster singles-doubles augmented by a perturbative triple excitations, CCSD(T), and density functional theory, DFT. The minimum energy path for the H2S addition to an isolated heme center of the heme protein is evaluated by adopting as a model the heme compound FeP(Im) (P = porphyrin; Im = imidazole). The FeP(Im)-H2S aduct is bound by 13.7 kcal/mol at the CCSD(T) level of theory. Relaxed potential energy curves for the lowest lying spin states of the H2S to FeP(Im) binding using DFT reveal that the binding process is associated with a "double spin-cross-over" reaction with the existence of long-distance van der Waals minima only 5-7 kcal/mol above the FeP(Im)-H2S ground state. The fact that the energy of the singlet ground state of FeP(Im)-H2S is so close in energy to the dissociation products FeP(Im) + H2S points towards the reversibility of the H2S adsorption/desorption process in biochemical reactions.

AB  - In this paper, spectroscopic and quantum mechanical investigation of nine 4-aryl-5-arylazo-3-cyano-6-hydroxy-2-pyridone dyes was performed, and obtained density functional theory (DFT) results were compared with experimental data. The structural and spectroscopic properties of azo-2-pyridone dyes were studied by DFT using B3LYP, CAM-B3LYP, and M06-2X methods with a 6-311++G(d,p) basis set. Comparison of results reveals that the scaled theoretical vibrational frequencies of azo dyes are in good agreement with experimental data. The time-dependent DFT calculated and experimental ultraviolet-visible (UV-vis) absorption spectra are also in good agreement. The effect of electron-donating -OCH3 and electron-withdrawing -NO2 groups on the structural parameters, vibrational frequencies, UV-vis absorption, and natural bond orbital (NBO) atomic charges were thoroughly analysed. Vibrational, UV-vis, and NBO analyses confirm that investigated dyes exist in the hydrazo tautomeric form in the solid state and ethanol solution. These analyses signify the occurrence of intramolecular charge transfer in these azo-pyridone dyes.

AB  - A series of ten 1-aryl-3-methylsuccinimides was synthesized and their solvatochromic properties were studied in a set of fifteen binary solvent mixtures. The solute-solvent interactions were analyzed on the basis of the linear solvation energy relationship (LSER) concept proposed by Kamlet and Taft. The electronic effect of the substituents on the UV-Vis absorption and NMR spectra was analyzed using the simple Hammett equation. Moreover, the B3LYP, CAM-B3LYP, and M06-2X functionals using the 6-311G(d,p) basic set have been assessed in light of the position of experimental absorption maxima obtained for these compounds. The integration grid effects have also been evaluated. An interpretation of the substituent-effect transmission through the molecular skeleton and the nature of the HOMO and LUMO orbitals based on quantum-chemical calculations is given. The values of partial atomic charges from the atomic polar tenzors (APT), natural population analysis (NBO), and charges fit to the electrostatic potential using the B3LYP, CAM-B3LYP, and M06-2X methods are produced and correlated with different experimental properties. In order to estimate the chemical activity of the molecule, the molecular electrostatic potential (MEP) surface map is calculated for the optimized geometry of 1-phenyl-3-methylsuccinimide.

AB  - Conglutins represent the major peanut allergens and are renowned for their resistance to gastrointestinal digestion. Our aim was to characterize the digestion-resistant peptides (DRPs) of conglutins by biochemical and biophysical methods followed by a molecular dynamics simulation in order to better understand the molecular basis of food protein allergenicity. We have mapped proteolysis sites at the N- and C-termini and at a limited internal segment, while other potential proteolysis sites remained unaffected. Molecular dynamics simulation showed that proteolysis only occurred in the vibrant regions of the proteins. DRPs appeared to be conformationally stable as intact conglutins. Also, the overall secondary structure and IgE-binding potency of DRPs was comparable to that of intact conglutins. The stability of conglutins toward gastro-intestinal digestion, combined with the conformational stability of the resulting DRPs provide conditions for optimal exposure to the intestinal immune system, providing an explanation for the extraordinary allergenicity of peanut conglutins.

abstract = "Conglutins represent the major peanut allergens and are renowned for their resistance to gastrointestinal digestion. Our aim was to characterize the digestion-resistant peptides (DRPs) of conglutins by biochemical and biophysical methods followed by a molecular dynamics simulation in order to better understand the molecular basis of food protein allergenicity. We have mapped proteolysis sites at the N- and C-termini and at a limited internal segment, while other potential proteolysis sites remained unaffected. Molecular dynamics simulation showed that proteolysis only occurred in the vibrant regions of the proteins. DRPs appeared to be conformationally stable as intact conglutins. Also, the overall secondary structure and IgE-binding potency of DRPs was comparable to that of intact conglutins. The stability of conglutins toward gastro-intestinal digestion, combined with the conformational stability of the resulting DRPs provide conditions for optimal exposure to the intestinal immune system, providing an explanation for the extraordinary allergenicity of peanut conglutins.",

AB  - For all dimethylnaphthalenes (DMNs) the transition from a planar ring conformation to a nonplanar one results in energy increase in the range 1.7-2.4 kcal/mol. There is a linear relationship between averaged rigidity constant and relative energy of DMNs. The relative stability of DMNs does not follow the aromatic stabilization based on NICS values. The ETS-NOCV analysis shows that more efficient bonding in the pi-electron system is the origin of enhanced stability in laterally substituted (CH3, Cl and NO2) naphthalenes. The results for C-aryl-CH3 system indicate more steric repulsion in going from 2,7-DMN to 1,8-DMN following the increase of relative energies.

AB  - In this study we present a theoretical investigation of the molecular properties of nitrodibenzofurans (NDFs) and dinitrodibenzofurans (DNDFs) and their relation to mutagenic activity. Equilibrium geometries, relative energies, vertical ionization potentials (IP), vertical electron activities (EA), electronic dipole polarizabilities, and dipole moments of all NDFs and three DNDFs calculated by Density Functional Theory (DFT) methods are reported. The Ziegler/Rauk Energy Decomposition Analysis (EDA) is employed for a direct estimate of the variations of the orbital interaction and steric repulsion terms corresponding to the nitro group and the oxygen of the central ring of NDFs. The results indicate differences among NDF isomers for the cleavage of the related bonds and steric effects in the active site. The results show a good linear relationship between polarizability ( LT alpha>), anisotropy of polarizability (Delta alpha), the summation of IR intensities (Sigma I-IR) and the summation of Raman activities (Sigma A(Raman)) over all 3N-6 vibrational modes and experimental mutagenic activities of NDF isomers in Salmonella typhimurium TA98 strain. The polarizability changes with respect to the nu(sNO+CN) vibrational mode are in correlation with the mutagenic activities of NDFs and suggest that intermolecular interactions are favoured along this coordinate.

AB  - A new Zn(II)-based potential chemotherapeutic agent was synthesized from the ligand 2-quinolinecarboxaldehyde selenosemicarbazone (Hqasesc). Single crystal X-ray diffraction analysis showed that the Zn(II) complex consists of a cation [Zn(Hqasesc)(2)](2+), two perchlorate anions and one ethanol solvent molecule. The interaction of calf thymus (CT) DNA and human serum albumin (HSA) with the Zn(II) complex was explored using absorption and emission spectral methods, and also has been supported by molecular docking studies. The complex has more affinity to minor DNA groove than major, with no significant intercalation. The HSA interaction studies of the complex revealed the quenching of the intrinsic fluorescence of the HSA through a static quenching mechanism. The antitumor activity of the ligand and the complex against pancreatic adenocarcinoma cell line (AsPC-1) and acute monocytic leukemia (THP-1) cells was evaluated. Both compounds are strong concentration-dependent apoptosis inducers in THP-1 cells. While Hqasesc in AsPC-1 cells induces apoptosis only at the highest concentration, treatment with the Zn complex shows a concentration-dependent apoptotic response, where the treated cells are arrested in the G1-to-S phase accompanied with extensive activation of caspase-8 and -9. These results indicate that the ligand and Zn(II) complex display cell phenotype specific activity.

AB  - Seven symmetrical 2,6-distyrylpyridines, phenyl-substituted with hydrogen-bond donors, hydrogenbond
acceptors, halogens and hydrophobic moieties were synthesized and their spectroscopic characterization
was done. Solvent effects on the absorption and fluorescence spectra were analyzed and quantified
using the Kamlet–Taft and Catalán approach. The obtained results were rationalized by comparison of
electrostatic potentials of the molecules in the ground and in excited state and by comparison of the frontier
molecular orbitals (HOMO and LUMO), derived from quantum-mechanical calculations (HF, DFT,
MP2). Analysis of the results revealed an important influence of non-specific (dispersive) interactions
on the solvatochromic behavior of the compounds. 1D and 2D NMR data, in silico obtained conformational
assembly of the compound, and the NMR analysis of molecular flexibility in solution (NAMFIS), were used
to estimate population of conformers and to deconvolute the UV-Vis spectrum of representative derivative;
inferring that the conformational assembly is more complex than was assumed in so far published
literature data for this class of compounds. Along with this, the emission spectra of the representative
compounds were decomposed by the Multivariate Curve Resolution analysis.

Two nitro derivatives of azabenzo[a]pyrene N-oxide: Electronic properties and their relation to mutagenic activity

AB  - The equilibrium geometries, relative energies, IR and Raman spectra, vertical ionization potentials (IP), vertical electron affinities (EA), dipole moments (mu), electronic dipole polarizabilities (alpha), and molecular electrostatic potentials (MEP) of two species that show very high mutagenicity, 1-nitro-6-azabenzo[a]pyrene N-oxide (1-N-6-ABPO) and 3-nitro-6-azabenzo[a]pyrene N-oxide (3-N-6-ABPO), are investigated by means of Density Functional Theory (DFT) using B3LYP functional with different basis sets. The 3-N-6-ABPO isomer was estimated to be much more mutagenic in Salmonella typhimurium tester strain TA98 (396 000 revertants/nmol) than 1-N-6-ABPO (36 100 revertants/nmol) (Fukuhara et al., 1992). The results show that for both isomers the structural, energetic, and vibrational properties are similar. The orientation of the nitro group with respect to the plane of the aromatic system as well as the nitroreduction and oxidation reaction and polarizability seem not be important for the determination of different mutagenic behavior of these isomers. However, the dipole moment of 3-N-6-ABPO is about 3 times that of 1-N-6-ABPO. The larger dipole moment and the different electronic charge distribution of 3-N-6-ABPO compared to 1-N-6-ABPO imply stronger electrostatic and inductive molecular interactions so that the active site of the enzyme involved in the mutagenic activation can more effectively bind 3-N-6-ABPO compared to 1-N-6-ABPO.

AB  - Theoretical charge density analysis of the thioureido based compound 4-methyl-3-thiosemicarbazide (MeTSC) is used in this study with the aim to provide additional insight into electronic features of the thioureido sulfur acceptor and the corresponding D-H...S hydrogen bonding (D=N, C). The present work is motivated by our earlier experimental charge density study on the same compound that pointed out to a great flexibility of the thioureido S acceptor and its ability to adjust the lone pair electron density to the donor groups in simultaneous hydrogen bonding. Through the additional theoretical approach we were able to single out different fragments of MeTSC crystal and to carefully follow the changes in electron density properties of the S acceptors belonging to: isolated MeTSC monomers (i.e. two crystallographically independent molecules), eight D-H...S bonded dimers and MeTSC molecules placed in full crystal environment, where each S atom engages in four hydrogen bonds. Deformation density of the sulfur's lone electron pair, topological properties of D-H...S interactions and electrostatic potential are here examined in order to comprehend the mutual influence and potential cooperative effects of the four simultaneously formed interactions to each of the S acceptors. The hydrogen bonding involving thioureido S acceptor is also investigated in terms of the energetic properties of the eight real MeTSC dimers existing in the crystal structure, and additional systems MeTSC/MeOH and acetone/MeOH. The latter systems are designed with the purpose of direct comparison and ranking of interactions involving thioureido S to those involving more conventional, carbonyl O acceptor. Energetic features were thoroughly studied through electrostatic interactions energies (XD2006), cohesive energies (CRYSTAL09) and ab initio approach employing the coupled-cluster single S and doubles augmented by a perturbational correction for connected triple excitations (CCSD(T)) method.

AB  - The physico-chemical properties of nitroazaphenanthrene isomers: 4-nitro-9-azaphenanthrene (4-N-9-Aph), 5-nitro-9-azaphenanthrene (5-N-9-Aph), 6-nitro-4-azaphenanthrene (6-N-4-Aph), 8-nitro-1-azaphenanthrene (8-N-1-Aph), and 8-nitro-4-azaphenanthrene (8-N-4-Aph) have been investigated theoretically using Density Functional Theory (DFT) calculations. Equilibrium geometries, relative stability, ionization potentials, electron affinities, molecular electrostatic potentials, dipole moments, electric polarizabilities, and vibrational properties of these isomers are presented. Averaged O-N-C-C dihedral angle, dipole moment, polarizability, the summation of IR intensities (Sigma I-IR) and the summation of Raman activities (Sigma A(Raman)) over all 3N-6 vibrational degrees of freedom are sensitive to the structure of isomers. A very good linear relationship between Sigma A(Raman) values (R = 1.00) and the Salmonella typhimurium strain TA98(-S9) mutagenic activity of the investigated nitroazaphenanthrene isomers (Tokiwa et al., 2003) reveals a very important role of inductive and dispersive forces on the mutagenic pathways of the investigated isomers.

AB  - To complement a previous UV study, we present a quantitative evaluation of substituent effects on spectroscopic data (H-1 and C-13 NMR chemical shifts as well as FT-IR absorption frequency) applied to N, N'-bisarylmalonamides, using simple and extended Hammett equations as well as the Swain-Lupton equation. Furthermore, the DFT CAM-B3LYP/6-311+G(d,p) method was applied to study the impact of different solvents on the geometry of the molecules and their spectral data. Additionally, experimental data are correlated with theoretical results; excellent linear dependence was obtained. The overall results presented in this paper show that N, N'-bisarylmalonamides are prominent candidates for model molecules.
