In the title molecule, C13H16N4O3, the mean planes of the phenyl and triazole rings are nearly perpendicular to one another as a result of the intramolecular C-H center dot center dot center dot O and C-H center dot center dot center dot pi(ring) interactions. In the crystal, layers parallel to (101) are generated by O-H center dot center dot center dot N, N-H center dot center dot center dot O and N-H center dot center dot center dot N hydrogen bonds. The layers are connected by inversion-related pairs of C-H center dot center dot center dot O hydrogen bonds. The experimental molecular structure is close to the gas-phase geometryoptimized structure calculated by DFT methods. Hirshfeld surface analysis indicates that the most important interaction involving hydrogen in the title compound is the H center dot center dot center dot H contact. The contribution of the H center dot center dot center dot O, H center dot center dot center dot N, and H center dot center dot center dot H contacts are 13.6, 16.1, and 54.6%, respectively.

Treatment of 3-methylcyclohexanone with ethyl formate in the presence of sodium methoxide afforded sodium (2-methyl-6-oxocyclohexylidene)methanolate which reacted with aminopyrazoles, aminotriazole, and aminotetrazole to produce fused quinazoline derivatives; its reactions with cyanothioacetamide, cyanoacetamide, and cyanoacetohydrazide gave tetrahydroquinoline-3-carbonitrile derivatives. The reactions of 8-methyl-2-sulfanyl-5,6,7,8-tetrahydroquinoline-3-carbonitrile with alkylating agents led to the formation of thieno[2,3-b]quinoline derivatives. DFT computational studies of the synthesized compounds were carried out using B3LYP/6-311+G** and HF/6-311+G** approximations. The calculated HOMO and LUMO energies showed that charge transfer occurs in their molecules.

A series of vital complexes of [Se (L-n) (Cl)(x)]center dot yCl (where n = L-1, L-2, L-3 and L-4; x = 1, 2, or 3 and y = 1, 2, or 3) and [Ru (L-n) (Cl)(x) (H2O)(y)]zCl (where x = 2 or 3; y = 0,1 or 2 and z = 0 or 1) have been synthesized from the chemical reactions between ruthenium (III) or selenium (IV) salts and tri-substituted s-triazine derivatives (L-1 = N-2-(4-chlorophenyl)-N-4,N-6-di (pyrimidin-2-yl)-1,3,5-triazine-2,4,6-triamine; L-2 = N-2-(4-chlorophenyl)-N-4- (pyrimidin-2-yl)- N-6-(thiazol-2-yl)-1,3,5-triazine-2,4,6-triamine; L-3 = 6-chloro-N-2-(pyrimidin-2-yl)-N-4-(1H-1,2,4-triazol-3-yl)-1,3,5-triazine-2,4-diamine and L-4 = 6-chloro-N-2-(4-chlorophenyl)-N-4-(pyrimidin-2-yl)-1,3,5-triazine-2,4-diamine). The structural was investigated using of elemental analyses, molar conductance, IR, UV-Vis, magnetic susceptibility, H-1, C-13 NMR spectra and thermal analyses. The surface morphology behaviors of selenium (IV) and ruthenium (111) complexes were studied based on scanning and transmittance electron microscopes. The crystalline nature of s-triazine complexes have been investigated using X-ray powder diffraction spectra. Spectral results were concluded that the ligand acts as a neutral bidentate for (L-1 and L-4) and tridentate for (L-2 and L-3), and coordinates through the nitrogen atom of triazine ring and nitrogen atoms of (pyrimidine, thiazole, and triazole) rings towards metal ion. The cytotoxic IC50 results of the free L-n ligands and its selenium (IV) complexes in vitro against the human colon and lung cancer cell lines introduced a promising efficiency.

In vitro genotoxicity testing that employs metabolically active human cells may be better suited for evaluating human in vivo genotoxicity than current bacterial or non-metabolically active mammalian cell systems. In the current study, 28 compounds, known to have different genotoxicity and carcinogenicity modes of action (MoAs), were evaluated over a wide range of concentrations for the ability to induce DNA damage in human HepG2 and HepaRG cells. DNA damage dose-responses in both cell lines were quantified using a combination of high-throughput high-content (HTHC) CometChip technology and benchmark dose (BMD) quantitative approaches. Assays of metabolic activity indicated that differentiated HepaRG cells had much higher levels of cytochromes P450 activity than did HepG2 cells. DNA damage was observed for four and two out of five indirect-acting genotoxic carcinogens in HepaRG and HepG2 cells, respectively. Four out of seven direct-acting carcinogens were positive in both cell lines, with two of the three negatives being genotoxic mainly through aneugenicity. The four chemicals positive in both cell lines generated HTHC Comet data in HepaRG and HepG2 cells with comparable BMD values. All the non-genotoxic compounds, including six non-genotoxic carcinogens, were negative in HepaRG cells; five genotoxic non-carcinogens also were negative. Our results indicate that the HTHC CometChip assay detects a greater proportion of genotoxic carcinogens requiring metabolic activation (i.e., indirect carcinogens) when conducted with HepaRG cells than with HepG2 cells. In addition, BMD genotoxicity potency estimate is useful for quantitatively evaluating CometChip assay data in a scientifically rigorous manner.

We report in this work the synthesis, crystal structures analyses, and nonlinear-optical (NLO) properties of three Schiff bases with halogens and triazole moieties: (E)-1-(4-bromophenyl)-N-(1H-1,2,4-triazol-3yl)methanimine L1, (E)-1-(4-bromophenyl)-N-(4H-1,2,4-triazol-3-yl)methanimine L2, and (E)-1-(4chlorophenyl)-N-(4H-1,2,4-triazol-3-yl)methanimine L3. The three molecules are built on the basis of the same backbone formed by two aromatic rings (phenyl and triazole) linked by imine bridge. The two first compounds L1 and L2 contain tautomers of the Schiff base, where a phenyl ring is substituted by a bromine atom. The third one, L3, is similar to L2 but contains a chlorine atom instead of bromine. In crystals formed by these three Schiff bases the three dimensional networks are formed by supramolecular interactions such as hydrogen bonds, C-X…pi and X…X (X = Cl or Br) contacts. Complementary Hirshfeld surface analyses were carried out to investigate and quantify the contributions of the different intermolecular interactions within the supramolecular assemblies. These analyses reveal that the main contributions in the studied compounds are provided by the H center dot center dot center dot H and N center dot center dot center dot H interactions that represent-53% (for L1),-49% (for L2) and-50% (for L3) of the total contributions to the Hirshfeld surface. The nonlinear optical properties are investigated by nonlinear diffuse femtosecond-pulse reflectometry and are compared with those of the reference material LiNbO3, in particular regarding the temporal evolution.

Aminotriazole isomers with high nitrogen content show potential affinity for U(VI). Combining the advantages of both aminotriazole and cellulose, two n-aminotriazole isomers modified cellulose microspheres (n-ATARs, n = 3, 4) were newly prepared as adsorbents via radiation technology. Batch adsorption experiments showed that n-ATARs possessed good adsorption capacity of U(VI) in the order of 3-ATAR > 4-ATAR, and the adsorption process followed the Langmuir-Freundlich isotherm model and the pseudo-second-order kinetic model. Both n-ATARs exhibited good selectivity and reusability. Besides, 3-ATAR and 4-ATAR were more suitable for the extraction of trace amount of U(VI) from the contaminated groundwater and the simulated seawater, respectively. The effect of amino position on triazole ring on adsorption behavior of n-ATAR was studied and explained by DFT calculation. Finally, the adsorption mechanism of U(VI) onto n-ATARs was revealed to be inner-sphere complexation via different 1:1 or 1:2 coordination models by FTIR, MS, XPS analysis and DFT calculation.

Aims and Objectives: An efficient and facile DBU catalysed synthesis of highly significant motif 5,7-disubstituted-1,2,4-triazolo[1,5-a]pyrimidines under solvent-free condition has been reported. Materials and Methods: To a round bottom flask, 1.0 mmol of chalcone (1), 1.5 mmol of 3-amino-1,2,4-triazole (2) and 30 mol% of DBU were added at 70 degrees C and stirred in solvent-free condition. After the completion of the reaction (monitored by TLC), water (10 ml) was added. The aqueous layer was extracted with ethyl acetate (3 x 10 ml). The combined organic layers were dried over anhydrous Na2SO4. The combined organic layers were evaporated under reduced pressure and the resulting crude product was purified by column chromatography by using ethyl acetate and hexane as eluent. Results: Reaction using chalcone and 3-amino-1,2,4-triazole as model substrates were carried out under different reaction conditions and it was observed that 30 mol% of DBU under the solvent-free condition at 70 degrees C was the optimum temperature for the proposed synthesis. Conclusion: Use of DBU (an organocatalyst) as a base, operational simplicity, high yield of products and short reaction time are some of the significant advantages associated with the proposed strategy.

The interfacial design is critical in preparing high-performance mixed matrix membranes (MMMs), especially for the separation of larger sized components from mixtures. Herein, a facile and novel strategy was employed to design covalently linked zeolitic imidazolate framework-8-polydimethylsiloxane (ZIF-8@PDMS) MMMs without interfacial defects by a onestep synthesis route for ethanol recovery from ethanol aqueous solution. In this strategy, 3-glycidyloxypropyltrimethoxysilane (GOPTS) worked as the covalent linker of PDMS and amine-functionalized ZIF-8 nanoparticles (AZIF-8) simultaneously. The chemical structures and morphologies of AZIF-8 and AZIF-8@PDMS MMMs were demonstrated by various characterization techniques. The results exhibited that AZIF-8 and the MMMs were successfully prepared and AZIF-8 as the filler displayed better dispersion in the PDMS matrix and compatibility with the PDMS matrix as compared to ZIF-8 or GOPTS-modified ZIF-8 (GZIF-8). Therefore, AZIF-8@PDMS MMMs showed more excellent separation performance than ZIF-8 or GZIF-8-filled MMMs. In particular, AZIF-8@PDMS MMM with 7 wt % AZIF-8 loading exhibited the highest separation factor of 17.7 and a comparable total flux of 585.6 g/m(2) h at 40 degrees C with 5 wt % ethanol aqueous solution, which were improved by 176.6 and 34.5%, respectively, in comparison with the pristine PDMS membrane, breaking the trade-off effect between the flux and separation factor. This study might provide some new insights into the fabrication of high-performance MMMs for pervaporation recovery of various organic systems.
