The novel flame retarded unsaturated polyester resins have been developed and prepared by introduction of high nitrogen content additives into the polymer matrix in order to verify their effectiveness in the formation of swollen carbonaceous char inhibiting the burning process of the polymer. The intumescent flame retardants (IFRs) based on mixture or metal complex were developed and characterized by particle size distribution, Fourier-transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), powder X-ray diffraction (XRD), elemental analysis (CHN) and thermogravimetric analysis (TGA). The evaluation of the efficiency of IFRs addition on the flammability and smoke emission of the unsaturated polyester resins (UP) was carried out using the fire hazard (UL-94), limiting oxygen index (LOI) and cone calorimeter (CC) tests, as well as smoke density chamber tests. The volatile compounds evolved during the burning of materials were determined using a steady state tube furnace and a gas chromatograph with mass spectrometer. Furthermore, the prepared materials were subjected to differential scanning calorimetry (DSC), thermogravimetric analysis and water resistance tests. The mechanical properties of the materials were investigated using Shore D hardness and dynamic mechanical thermal analysis (DMA). The structural evaluation of the manufactured materials and samples after the cone calorimetry tests was carried out using scanning electron microscopy (SEM). It was found that the incorporation of new intumescent flame retardants led to the formation of carbonaceous char layers’ inhibiting the decomposition process and limiting the smoke emission. The most promising results were obtained for the resin containing complex designated as ZN3AT, for which the highest reduction in maximum values of heat release rate (419 kW/m(2)) compared to unmodified polymer (792 kW/m(2)) were recorded. Apart from that, the prepared intumescent flame retardants affect the cross-linking process as well as the thermal and mechanical properties of the UP.

Grapevine (Vitis vinifera L.) is a crop of major economic importance. However, grapevine yield is guaranteed by the massive use of pesticides to counteract pathogen infections. Under temperate-humid climate conditions, downy mildew is a primary threat for viticulture. Downy mildew is caused by the biotrophic oomycete Plasmopara viticola Berl. & de Toni, which can attack grapevine green tissues. In lack of treatments and with favourable weather conditions, downy mildew can devastate up to 75% of grape cultivation in one season and weaken newly born shoots, causing serious economic losses. Nevertheless, the repeated and massive use of some fungicides can lead to environmental pollution, negative impact on non-targeted organisms, development of resistance, residual toxicity and can foster human health concerns. In this manuscript, we provide an innovative approach to obtain specific pathogen protection for plants. By using the yeast two-hybrid approach and the P. viticola cellulose synthase 2 (PvCesA2), as target enzyme, we screened a combinatorial 8 amino acid peptide library with the aim to identify interacting peptides, potentially able to inhibit PvCesa2. Here, we demonstrate that the NoPv1 peptide aptamer prevents P. viticola germ tube formation and grapevine leaf infection without affecting the growth of non-target organisms and without being toxic for human cells. Furthermore, NoPv1 is also able to counteract Phytophthora infestans growth, the causal agent of late blight in potato and tomato, possibly as a consequence of the high amino acid sequence similarity between P. viticola and P. infestans cellulose synthase enzymes.

Herein, perylene diimide (PDI)/oxygen-doped g-C3N4 nanosheets (O-CN) n-n heterojunction photocatalyst was prepared by an in-situ electrostatic assembling. The pi-pi interaction between self-assembled PDI and O-CN could lead to the electron delocalization effect to facilitate the electron migration. Self-assembled PDI could broaden the visible response range of O-CN to produce more photogenerated carries. Moreover, the interlaced band structures of O-CN and self-assembled PDI could result in a built-in electric field to promote the interfacial charge separation. Besides, many active species (h(+), O-center dot(2-) and O-1(2) ) could be accumulated to improve the oxidation ability of PDI/O-CN. Therefore, PDI/O-CN exhibited enhanced visible photocatalytic oxidation activities towards disinfection, degradation and oxygen evolution. The optimum PDI/O-CN inactivated 96.6% of Staphylococcus aureus cells within 3 h, while O-CN only killed 62.2%. Additionally, the phenol degradation rate and evolved oxygen amount in 2 h of PDI/O-CN-40% were 3.6 and 1.8 times as high as those of O-CN, respectively.

Annulated C-beta-D-glucopyranosyl heterocycles were synthesized and tested as inhibitors of glycogen phosphorylase. 2-(beta-D-Glucopyranosyl)-1H-imidazo[4,5-b] pyridine was formed by ring-closure of O-perbenzoylated C-beta-D-glucopyranosyl formic acid with 2,3-diaminopyridine in the presence of triphenylphosphite. Cyclisations of bromomethyl 2,3,4,6-tetra-O-benzoyl-beta-D-glucopyranosyl ketone with a set of 2-aminoheterocycles resulted in constitutionally reversed C-beta-D-glucopyranosyl imidazoles fused by pyridine, pyrimidine, thiazole, 1,3,4-thiadiazole, benzothiazole and benzimidazole. O-Debenzoylation of the above compounds was effected by standard transesterification to get the test compounds. The 1H-imidazo[4,5-b] pyridine proved to be a low micromolar inhibitor (K-i = 21.1 mu M) of rabbit muscle glycogen phosphorylase b, while the other heterocycles displayed weak or no inhibition against the same enzyme.

Solvothermal reactions of Zn(NO3)(2)center dot 6H(2)O, 3-amino-1,2,4-triazole as well as three different carboxylate ligands afforded three novel coordination polymers: [Zn-2 (azdc) (atz) (OH) (H2O)](n) (1), {[Zn-1.5 (btc)(0.5) (atz)]center dot 1.5H(2)O}(n) (2), and {[Zn-4 (nipa)(2) (atz)(3)(OH) (H2O)]center dot 2H(2)O}(n) (3) (H(2)azdc = 4,4′-azobenzoic acid, H(4)btc = 1,2,4,5-benzenetetracarboxylic acid, 5-H(2)nipa = 5-nitroisophthalic acid, Hatz = 3-amino-1,2,4-triazole). Moreover, the three coordination polymers have been characterized by IR spectroscopy, elemental analysis, single-crystal X-ray diffraction, and powder X-ray diffraction techniques. Complex 1 reveals a 2D layer structure, which is further connected through pi-pi stacking interactions forming a 3D supramolecular network. Complex 2 exhibits a 3D porous framework with 1D open channels. Complex 3 shows a 3D pillared-layer framework. Notably, the thermal decomposition processes of 1-3 were investigated by simultaneous TG-DSC techniques. The TG curves reveal that complexes 1-3 possess pretty good thermostability up to 321 degrees C, 416 degrees C and 418 degrees C, respectively. The apparent activation energy E (E-1 = 194.975 kJ mol(-1), E-2 = 220.360 kJ mol(-1), E-3 = 223.600 kJ mol(-1)) and the pre exponential factor A of skeleton collapse for the complexes 1-3 were calculated by the integral Kissinger’s method and Ozawa-Doyle’s method. The structural stability could be illustrated from the point of thermal decomposition kinetics.

Mitochondria are known as powerhouse of cells and play the role of a bridge in redox balance, cell apoptosis, and autophagy. ROS accumulation can cause mitochondria damage, while the injured mitochondria will further enhance ROS levels reciprocally. Herein, we synthesized a novel series of [1,2,4] triazolo[1,5-a]pyrimidine-based compounds 4a-4v and tested their anti-proliferation efficacy against gastric cancer cell line MGC-803. Among them, compounds 4o and 4p inhibited gastric cancer cells at micromolar level. Compound 4o caused G2/M arrest and induced mitochondria-dependent apoptosis in MGC-803 and SGC-7901. However, inhibiting apoptosis pathway cannot prevent the inhibitory activity of compound 4o against gastric cancer cell. To our surprising, ROS level was increased by compound 4o and elevation of ROS could be rescued by NAC. In accordance with that, NAC absolutely prevented the anti-proliferation efficacy of compound 4o. We further found that autophagy inhibitor CQ rather than 3-MA partially reversed inhibitory activity of compound 4o in MGC-803 cells. Taken together, compound 4o exhibited its anti-proliferative activity via increasing ROS level and inducing autophagy, thus leading to apoptosis of gastric cancer cells. Therefore, compound 4o may support further development of lead compounds for gastric cancer therapy via mitochondria pathway. (C) 2020 Elsevier Masson SAS. All rights reserved.

Visualization of intracellular transport pathways is crucial to investigate the internalization mechanism and understand the intracellular behavior of nanomaterials. Herein, we rationalized the design of micellar nanopartides (NPs for ratiometric fluorescent mapping of intracellular pH and glutathione (GSH), two essential parameters for maintaining normal cellular functions. Specifically, pH-sensitive naphthalimide-based probe (NPI) and pH-inert rhodamine B (RhB) were covalently labeled to double hydrophilic block copolymers (DHBCs) using the thiolactone chemistry, enabling the covalent attachment of NPI and RhB to one molecule with a redox-responsive disulfide linkage. The dually labeled DHBCs exhibited blue/orange dual emissions in acidic pH, which was further converted into green/orange dual emissions in neutral pH because of the deprotonation of NPI moieties and the sole green emission in the presence of GSH at neutral pH because of the decreased Forster resonance energy transfer efficiency between an NPI donor and an RhB acceptor as a result of GSH-mediated cleavage of disulfide bonds. These remarkable ratiometric fluorescence changes allowed for not only the simultaneous mapping of the intracellular pH and GSH but also the intracellular transport pathways of internalized NPs.

Using a set of physicochemical (ellipsometry and contact angle measurements), electrochemical (potentiometric anode polarization and electrochemical impedance spectroscopy), and corrosion (periodic moisture condensation test) methods, the properties of adsorption films formed on the AMg6 aluminum alloy surface by the chamber method in vapors of some amines of heterocyclic compounds, carboxylic acids, and their salts are studied. It is established that the use of the studied compounds in the chamber processing of the alloy increases-though not effectively enough-its corrosion resistance in a humid atmosphere. The most promising inhibitors are carboxylic acids themselves; the optimum temperature for surface treatment with them is 140 degrees C. One-hour treatment of steel with pairs of oleic, neodecanoic acid, and carboxylic acid A at this temperature gives rise to the formation of nanoscale adsorption films on the AMg6 alloy, which slightly hydrophilize the surface, but possess a protective aftereffect. Apparently, further improvement of chamber protection methods of the AMg6 alloy should consist in the selection of synergists for chamber corrosion inhibitors of the carboxylate type.
