The EFSA ‘Guidance on tiered risk assessment for edge-of-field surface waters’ underscores the importance of in silico models to support the pesticide risk assessment. The aim of this work was to use in silico models starting from an available, structured and harmonized pesticide dataset that was developed for different purposes, in order to stimulate the use of QSAR models for risk assessment. The present work focuses on the development of a set of in silico models, developed to predict the aquatic toxicity of heterogeneous pesticides with incomplete/unknown toxic behavior in the water compartment. The generated models have good fitting performances (R-2 : 0.75-0.99), they are internally robust (Q(2) loo: 0.66-0.98) and can handle up to 30% of perturbation of the training set (Q(2) Imo: 0.64-0.98). The absence of chance correlation was guaranteed by low values of R-2 calculated on scrambled responses (R-2 Y-scr: 0.11-0.38). Different statistical parameters were used to quantify the external predictivity of the models (CCCext: 0.73-0.91, Q(2) ext-Fn: 0.53-0.96). The results indicate that all the best models are predictive when applied to chemicals not involved in the models development. In addition, all models have similar accuracy both in fitting and in prediction and this represents a good degree of generalization. These models may be useful to support the risk assessment procedure when experimental data for key species are missing or to create prioritization lists for the general a priori assessment of the potential toxicity of existing and new pesticides which fall in the applicability domain.

8-Acetyl-7-hydroxy-4-methyl coumarin and 3-amion-1,2,4-triazole were used to prepare a Schiff base (Sbat). The [Ag(Sbat)(NO3)]center dot H2O and [Cu(Sbat)(OH)(H2O)(2)]center dot 3H(2)O complexes were separated by the reaction of the Schiff base with Ag(i) and Cu(ii) metal ions. All the prepared compounds were subjected to elemental and spectral analyses (IR, UV-vis, H-1 NMR, and mass spectroscopy). Moreover, the complexes were also subjected to TG analysis, molar conductance measurements, magnetic moment analysis, and XRD measurements. The value of the molar conductance designates their non-electrolytic character. The local minimum structure, global properties and nonlinear optical parameters of the Schiff base were calculated at the B3LYP/6-31++(d,p) level of theory and those of its complexes were calculated at the B3LYP/GENECP level. The electronic spectra in the UV-visible region of the Schiff base (Sbat) and [Ag(Sbat)(NO3)]center dot H2O and [Cu(Sbat)(OH)(H2O)(2)]center dot 3H(2)O complexes in DMSO as a solvent were investigated experimentally and theoretically using the time dependent density functional theory (TD-DFT) method at the CAM-B3LYP/6-311++G(d,p) level of theory. The studied compounds were screened for their in vitro antibacterial activity against three Gram-positive (B. subtilis, S. aureus and S. faecalis) and three Gram-negative bacteria (E. coli, N. gonorrhoeae and P. auregenosa). An antifungal assay was performed against two fungal (C. albicans and A. flavus) species. The Ag-Sbat complex showed the highest antimicrobial activity. The cytotoxic activity of the Schiff base and its silver complex was tested in vitro against the MCF-7 (breast cancer) and HCT-116 (colon cancer) cell lines.

Agouti signaling protein (ASP) is a secreted paracrine protein that has been widely reported to function in melanogenesis and obesity and could potentially be a core protein that regulates the color and fatty phenotype of P. sinensis. In this study, we screened out interacting proteins of ASP by combined co-immunoprecipitation mass spectrometry (CoIP-MS), yeast two hybrid (Y2H) analysis, and computational predictions. We performed docking of ASP with its well-known receptor melanocortin receptor 4 (MC4R) to predict the binding capacity and to screen out actual ASP interacting proteins, CoIP-MS was performed where identified 32 proteins that could bind with ASP and Y2H confirmed seven proteins binding with ASP directly. CoIP-MS and Y2H screening results including PPI prediction revealed that vitronectin (VIN), apolipoprotein Al (AP0A1), apolipoprotein B (APOB), and filamin B (FLNB) were the key interacting proteins of ASP. VTN, AP0A1, and APOB are functional proteins in lipid metabolism and various skin disorders, suggesting ASP may function in lipid metabolism through these partners. This study provided protein-protein interaction information of ASP, and the results will promote further research into the diverse roles of ASP, as well as its binding partners, and their function in different strains of P. sinensis.

Four C2H4N4 structural isomers are investigated with fs laser-induced breakdown spectroscopy. Plasma emissions, C I, H-alpha, the CN violet system (B-2 sigma(+)-X-2 sigma(+), Delta nu = 0 sequence) and C-2 swan system (d(3)pi(g)-a(3)pi(u), Delta nu = 0 sequence) are measured. The temporal evolution of the characteristic emission intensity is obtained for each emission and their lifetimes are calculated. The lifetimes of the molecular emissions are much longer than those of the atomic emissions. Characteristic emission intensities and lifetime are correlated with the molecular structures of the four isomers to a certain extent. Plasma temperature is extracted by fitting the spectrum of the CN violet system, B-2 sigma(+)-X-2 sigma(+); Delta nu = 0 sequence, and is weakly correlated with the molecular structures of the four isomers. Using the characteristic emission intensities as input, principal component analysis (PCA) and artificial neural network (ANN) analysis are performed and the individual isomers can be well identified with PCA or ANN.

Using a set of physicochemical (ellipsometry and contact angle measurements), electrochemical (electrochemical impedance spectroscopy and polarization measurements), and corrosion (periodic moisture condensation and salt fog tests) methods, the properties of adsorption films formed on copper by the chamber method from vapors of benzotriazol (BTA), 1H-1,2,4-triazole, tolyltriazole (TTA), 5-chloro-1,2,3-benzotriazole (CBTA), 3-amino-1H-1,2,4-triazole, and 4-amino-1H-1,2,4-triazole at a temperature of 100 degrees C are studied. It is shown that 1-h chamber treatment of copper with vapors of these compounds leads to the formation of nanoscale hydrophobic adsorption films on it, which inhibits the thermal growth of oxides, but stabilizes the passive state of the metal and increases its corrosion resistance. Among these different triazole compounds tested as chamber corrosion inhibitors, BTA and its substituted derivatives are distinguished. After a 1-h chamber treatment of copper, the protective aftereffect of the adsorption films of triazole derivatives grows symbatically with their saturated vapor pressure at the chamber treatment temperature, i.e., in the following increasing order: CBTA < TTA < BTA. This may indicate that the equilibrium adsorption films do not have time to form at 100 degrees C on the metal within this time period. After a prolonged (24 h or more) chamber treatment of copper with vapors of substituted benzotriazoles, equilibrium adsorption films of inhibitors are formed on it. In this case, the influence of the chamber inhibitor properties on their protective aftereffect alternates. Under such conditions, the least volatile and most hydrophobic substituted benzotriazole, i.e., CBTA, provide the best metal protection.

Four isostructural dinuclear lanthanide complexes based on 4-azotriazolyl-3-hydroxy-2-naphthoic acid (H(3)ATNA) and 3-hydroxy-2-naphthoic acid (H(2)NA) ligands, {[Ln(2)(HATNA)(2)(HNA)(2)(H2O)(4)].6DMF} (Ln = Dy (1), Tb (2), Sm (3), Eu (4); DMF = N,N-dimethylformamide) have been prepared and characterized by X-ray diffraction crystallography, dc/ac magnetic characterization, and fluorescent spectrometry. The crystallographic data reveal dinuclear lanthanide cores of complexes 1-4, bridged by phenoxo and mu(1,3) carboxyl groups. Each nine-coordinated Ln(III) ion is located in a slightly distorted monocapped square antiprism. The ligand of H(3)ATNA displays a unique antenna effect in complex 4. Complexes 1-3 display only two ligand-centered fluorescent emissive peaks around 450 and 600 nm, and complex 4 shows four characteristic Eu(III)centered emission bands at 593, 618, 653, and 698 nm under excitation at 348 nm. Complex 1 exhibits single-molecule magnet behavior that is rationalized through ab initio calculations.

In this work, (Z)-N-benzoyl-N ‘-(1H-1,2,4-triazol-3-yl)carbamimidothioic acid and its Mn(II), Co(II), Cu(II) and Cd(II) complexes were introduced for the first time. This carbonyl thiourea ligand was prepared by the reaction of 1H-1,2,4-triazol-3-amine with benzoyl isothiocyanate. The structural elucidation of these compounds was performed using elemental analysis and spectral and magnetic measurements. Octahedral structures of all complexes, except Cd(II) complex with a tetrahedral geometry, were confirmed by applying DFT structural optimization. The thermal decomposition behaviour of metal complexes of carbonyl thiourea ligand is discussed. The calculation of kinetic parameters for prepared complexes (E-a, A, Delta H*, Delta S* and Delta G*) of all thermal degradation stages has been evaluated using two comparable approaches. Antimicrobial and ABTS-antioxidant studies indicated potent activity of Cd(II) complex compared with the other investigated compounds. The cytotoxic activity of the prepared compounds was investigated in vitro. The results indicated potent activity of Mn(II) complex against both HePG2 (liver carcinoma) and MCF-7 (breast carcinoma) cancer cells.

Despite the increasing detection of emerging substances in the environment, the identity of most are left unknown due to the lack of efficient identification methods. We developed a non-target analysis method for identifying unknown substances in the environment by liquid chromatography/high-resolution mass spectrometry (LC/HRMS) with a product ion and neutral loss database (PNDB). The present analysis describes an elucidation method with elemental compositions of the molecules, product ions, and corresponding neutral losses of the unknown substance: (1) with the molecular formula, possible molecular structures are retrieved from two chemical structure databases (PubChem and ChemSpider); then (2) with the elemental compositions of product ions and neutral losses, possible partial structures are retrieved from the PNDB; and finally, (3) molecular structures that match the possible partial structures are listed in order of number of hits. A molecular structure with a higher number of hits is more similar to the structure of the analyzed substance. The performance of the non-target method was evaluated by simulated analysis of 150 LC/HRMS spectra registered in MassBank. First, all substances of the same mass data (41/41) and 68% (39/57) of the mass data of the same substances not registered in the PNDB were elucidated. It was demonstrated that 14% (7/52) and 31% (16/52) of the substances with no mass spectral data registered in the PNDB were obtained at the first and within the fifth place, respectively. Owing to the fact that 10 of the total hits occurred in product ions and neutral losses, almost 50% of the substances evaluated with this method were placed at the top 4 positions in the similarity ranking. Importantly, the proposed method is effective for analyzing mass spectral data that has not been registered in the PNDB and thus is expected to be used for a variety of non-target analyses.
