A metal-organic cocrystal, [Co(2-quin)(2)(3-ata)(2)]center dot[Co(2-quin)(2)(H2O)(2)] (1) (H-2-quin = 2-quinalidic acid and 3-ata = 3-amino-1,2,4-triazole), has been synthesized and characterized by elemental analysis as well as the single-crystal X-ray diffraction (SCXRD) technique. Compound 1 crystallizes in the triclinic space group P (1) over bar and shows significant hydrogen bonding interactions, leading to the formation of supramolecular polymers. Hirshfeld surfaces analysis has been performed to investigate the non-covalent interactions in the crystal packing. The cocrystal shows a good in vitro binding propensity with ctDNA, which was reflected by its high binding constant (K-b) value of 2412 M-1. A docking study has also been carried out to corroborate the experimental findings. (C) 2020 Elsevier Ltd. All rights reserved.

Novel bis[(thiazol-2-yl)acetonitrile] derivatives were prepared in good yields by the cyclocondensation of bis(bromoacetyl) derivatives with two equivalents of 2-cyanothioacetamide in dioxane at reflux. The bis[(thiazol-2-yl)acetonitrile] derivatives were taken as synthetic precursors for the synthesis of novel bis(aminoazolo[1,5-a]pyrimidines), bearing thiazole moiety. The target molecules were prepared by the three component one pot reaction of bis[(thiazol-2-yl)acetonitrile] derivatives, dimethylformamide-dimethylacetal and several of 3-aminopyrazoles in pyridine under microwave irradiation at 140 degrees C for 2 h. Using the same protocol, novel bis(aminotriazolo[1,5-a]pyrimidines), bis(aminopyrimido[1,2-a]benzimidazoles) and bis(aminopyrido [1,2-a]benzimidazoles), incorporating thiazole moieties, were prepared by using the appropriate heterocyclic amine or 2-(1H-benzoimidazol-2-yl)acetonitrile instead of 3-aminopyrazoles. The structure of the newly prepared thiazoles was confirmed via considering their elemental analyses and spectral data.

A facile method has been developed for the synthesis of Schiff bases derived from substituted and unsubstituted 3-amino- and 4-amino-1,2,4-triazoles. Condensation of the aminotrizoles with a variety of aromatic aldehydes afforded desired Schiff bases in excellent yields in 3-5 minutes of exposure to ultra-sound. The synthesized compounds were characterized by means of IR, (HNMR)-H-1 and Mass spectrometry. The synthesized compounds were also screened for their antibacterial potential against Gram-negative (Escherichia coli, Shigella sonnei, Pseudomonas aeruginosa and Salmonella typhi) and two Gram-positive (Staphylococcus aureus and Bacillus subtilis) strains.

Novel linear cationic poly(amide aminotriazole)s (PATnD) with secondary amine groups in the backbone were obtained by using azide-alkyne 1,3-dipolar cycloaddition reactions: metal- and solvent-free (thermal conditions, PATTnD) or copper(I)-catalyzed (Sharpless conditions, PATCnD). PATnD were investigated in vitro against strains of E. coli, P. aeruginosa, S. aureus, and S. epidermidis. Hemolytic activity was tested using human red blood cells (hRBC), and very low or no hemolytic activity was observed. The cytotoxicity of PATnD polymers against Human Gingival Fibroblasts (HGnF) cells was concentration-dependent, and significant differences between PATT1D and PATC1D were observed. The ability of these polymers to induce resistance against both Grampositive and Gram-negative bacteria was also assessed. Studied bacterial strains acquired resistance to catalytic polymers (PATCnD) in initial passages meanwhile resistance to thermal polymers (PATTnD) appears in later passages, being the increase of the minimum inhibitory concentration lower than in catalytic polymers. This result, together with the higher biocidal capacity of thermal polymers compared to catalytic ones, seems to suggest an influence of the regiospecificity of the polymers on their antibacterial characteristics. This study also demonstrates that PAT1D polymers, which do not appear to have strong hydrophobic residues, can exert significant antimicrobial activity against Gram-positive bacteria such as S. epidermidis. This pair of polymers, PATC1D and PATT1D, displays the greatest antimicrobial activity while not causing significant hemolysis along with the lowest susceptibility for resistance development of the polymers evaluated.

Interaction of methyl 3-ethoxy-2-(2,5-dichloro-3-thenoyl)acrylate (I) with 3-aminopyrazole and 3- amino-1,2,4-triazole generated the respective pyrazolo [1,5-alpha]pyrimidine (4) and triazolo[1,5-alpha]pyrimidine (7). The formation of 4 entails selective and consecutive displacement of the 3-ethoxy and methoxy (ester) anions in I by 3-NH2 and 1-NH of 3-aminopyrazole. On the other hand, the formation of 7 implies selective displacement of 3-ethoxy in I by the ring-NH followed by cyclocondensation involving the keto group in I and 3-NH2 of aminotriazole. This latter selective displacement sequence is also followed by 3-amino-5-hydroxypyrazole in its reaction with I. The structures of the new compounds are supported by microanalytical and spectral data.

Due to the harsh reaction conditions, high energy consumption, and numerous carbon emissions of the traditional Haber-Bosch method, the fixation of nitrogen under environmentally friendly and milder conditions is of great importance. Recently, photoelectrochemical (PEC) strategies have attracted extensive attention, where the catalysts with the advantages of costeffectiveness and improved efficiency are critical for the nitrogen reduction reaction (NRR). Herein, we synthesized nitrogen vacancies that contained g-C3N5 (NV-g-C3N5) and combined with BiOBr to construct the p-n heterostructure NV-g-C3N5/BiOBr, in which the double-electron transfer mechanism was constructed. In one side, the nitrogen vacancies store the electrons coming from the g-C3N5 and provide for the nitrogen activation when needed; in addition, NV-g-C3N5/BiOBr further separates photoinduced electrons and holes because of the matched Z-shaped energy band structure. The double-electron transfer mechanism effectively retards the recombination of charge carriers and ensures the support of high-quality electrons, which results in excellent PEC NRR performance without the addition of noble metals. Although yields and durability are insufficient, the described double-electron transfer mechanism manifests the potential of the non-noble metal material in the PEC NRR, providing a foundation for the design of a more affordable and efficient photocathode in nitrogen reduction.

Amino-functionalized ionic liquids (IL) are often applied to fix CO2. However, as far as we know, none of them have ever been reported to exhibit considerable physical CO2 capture. Herein, we describe an amino-functionalized room-temperature ionic liquid, 1-butyl-3-methylimidazolium 3-amino-1H-1,2,4-triazolate ([Bmim][ATZ]), with an unusual ultrafast physical CO2 capture at room temperature and atmospheric pressure. Within the time needed for a chemisorbent to reach an equilibrium, 15 adsorption and desorption cycles are finished for [Bmim][ATZ], with an accumulative molar ratio of up to 2.04. The CO2/IL ratio for one adsorption process reaches 0.14, which is 4 times the highest recorded physical CO2 solubility by [thtdp][Cl] (trihexyltetradecylphosphonium chloride). The first theoretical study on anion-anion interactions of ionic liquids is reported, which rationalizes the inhibition of chemical adsorption. These results provide a new perspective on the aspect of CO2 capture, as well as designing of ionic liquids.

In the present paper, twelve Schiff bases derived from 3-amino-1H-1,2,4-triazole (ATz) and various benzaldehydes, and salicylaldehydes were synthesized. The H-1, C-13, and N-15 NMR data are discussed in relation to the structure of ATz and its imine products. In addition, X-ray, ATR-FTIR, and UV-Vis analytical techniques are used for structure elucidation of ATz-based Schiff bases. It was found that the starting material, 3-amino-1H-1,2,4-triazole, exists as tautomeric mixture of three forms (Graphical Abstract) in solution, whereas in the solid state (C-13 and N-15 CPMAS data) potentially tautomeric proton is located on nitrogen atom traditionally marked as N-2 (Graphical Abstract, 2N-H structure). All investigated Schiff bases derived from salicylaldehydes exist in both phases as tautomeric equilibrium mixtures, where enol-imine forms are dominated structures. The positions of those equilibria only very slightly depend on substituents in phenol ring. Generally, the contributions of keto-amine forms in the solid state are higher comparing with DMSO solutions. (C) 2019 Published by Elsevier B.V.
