A porous Co-MOF for CO2 conversion and protective activity on infectious fever by reducing bacterial inflammatory response

By applying a mixed-ligand approach based on an amino functionalized ligand 1-aminobenzene-3,4,5-tricarboxylic acid (H(3)abta), a novel metal-organic framework (MOF) containing Co(II) ion {[Co-2.5(abta)(trz)(2) (H2O)]center dot 3H(2)O}(n) (1, Htrz = 1H-1,2,4-triazole) were produced via Co(NO3)(2)center dot 6H(2)O reacting with H(3)abta with the existence of Htrz as the co-ligand. The prepared catalyst 1a (activated 1) is abundant in the amino groups and open metal sites (OMSs), which is helpful to obtain high CO2 capacity of adsorption around room temperature and effectively convert CO2 to pentacyclic carbamate with the help of Bu4NBr as the cocatalyst. For the treatment of infectious fever, the colony-forming unit (CFU) was performed and the E. coli number in the mice was counted. Next, the inflammatory cytokines level in the infected mice was measured after the compound treatment. [GRAPHICS] .

Synthesis and properties of novel nitrogen- and oxygen-enriched dicationic 3,4-diaminotriazolium salts as attractive energetic materials

The incorporation of both fuel and oxidizer properties into a single molecule to effectively improve the oxygen balance of energetic compounds has become one of the most acceptable strategies for the design of modern high-energy-density materials (HEDMs). To identify more powerful and less sensitive HEDMs with favorable oxygen balance, novel nitrogen- and oxygen-enriched dicationic 3,4-diaminotriazolium salts were prepared via the quaternization of 3,4-diamino-triazole with 4,4′-bis(nitramino)azofurazan and 4,4′-bis(nitramino)azoxyfurazan, and then fully characterized. These compounds exhibited favorable thermal stabilities with decomposition temperatures up to 216 degrees C, high densities over 1.82 g.cm(-3) as well as acceptable sensitivities. In addition, the two-dimensional fingerprint spectra based on Hirshfeld surface analysis were adopted to illustrate structure-property relationships. Based on the combination of experimentally determined densities and heats of formation calculated with Gaussian 03, the energetic properties were determined using the EXPLO5 v6.02 program. The newly synthesized ionic salts displayed excellent detonation properties (V-d, 9115-9220 m.s(-1); P, 33.9-35.4 GPa), comparable to those of 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane (HMX), thus highlighting their potential in energetic material applications.

Synthesis of New Chiral Triazoles Linked 1,5-Benzodiazepine Conjugates via Copper-Catalyzed 1,3-Dipolar Cycloaddition Reaction

A simple synthesis of 1,4-disubstituted 1,2,3-triazoles linked-1,5-benzodiazepinones was performed via a Cu(I)-catalyzed 1,3-dipolar alkyne-azide coupling reaction (CuAAC). A new chiral 1,5-benzodiazepine conjugates moiety containing alkyne spacers is designed and used as dipoles to give the access to the target cycloadducts with high yields. Both chiral center and freeze conformations allow to reach important diastereoselectivity from 70 up to 100 %.

A real-time and highly sensitive fiber optic biosensor based on the carbon quantum dots for nitric oxide detection

Nitric oxide (NO) is a signal molecule with a wide range of functions and unique properties in organisms. A novel fluorescent probe composed of carbon quantum dots (CQDs) with o-phenylenediamine groups was prepared by the microwave method to detect NO selectively. The mechanism of the reaction between CQDs and NO was established by a series of characterization methods, such as fluorescence spectrophotometer, UV-vis absorption spectrophotometer and transmission electron microscope. The result showed that the o-phenylenediamine groups on the surface of the CQDs can react with NO to form an electron-free triazole structure, leading to the decrease of fluorescence of the CQDs. Furthermore, a new optical fiber sensing system based on the CQDs was constructed to detect NO with a low detection limit of 9.12 nM at laser power of 280 mW. In addition, the NO optic fiber biosensor also was used to detect NO concentration in real human serum samples.

A simple and efficient strategy for constructing nitrogen-rich isomeric salts and cocrystal through pK(a) calculation

Nitrogen-rich energetic salts and cocrystal have attracted considerable attention in recent years. To assess the formation of cocrystal or salt, acid dissociation constant (pK(a)) values of the isomeric co-formers were calculated in this work and significant differences were observed. Two salts and one cocrystal based on H2BT (1H, 1’H-5,5′-bitetrazole), DATr (4,5-diamino-4H-1,2,4-triazole), 1MAT (1-methyl-5-aminotetrazole) and 2MAT (2-methyl-5-aminotetrazole) were synthesized, which corresponding to the different pK(a) values of three isomeric coformers. Single crystal structure analysis reveals that all compounds are formed by layered stacking structure with pi-pi stacking and rich hydrogen bonds, resulting in the insensitivity towards impact and friction (impact sensitivity > 40 J, friction sensitivity > 360 N). To the best of our knowledge, it is the first time to report the cocrystal of H2BT. The study results provide a utility method to seek for suitable coformers and design energetic cocrystal through the calculation of pK(a). (C) 2020 Elsevier B.V. All rights reserved.

z Enantioselective residues and toxicity effects of the chiral triazole fungicide hexaconazole in earthworms (Eisenia fetida)

The enantioselective toxic effect and environmental behavior of chiral pesticides have attracted increasing research attention. In this study, the enantioselective toxicity and residues of hexaconazole (HEX) in earthworms (Eisenia fetida) were investigated. In the present study, significant enantioselective degradation characteristics were observed in artificial soil with the R-enantiomer preferentially degrading (p < 0.05); however, no significant enantioselective bioaccumulation was observed in the earthworms (p > 0.05). The acute toxicity of S-(+)-HEX was higher than that of R-(-)-HEX in earthworms, with 48-h LC50 values of 8.62 and 22.35 mu g/cm(2), respectively. At 25 mg/kg, enantiospecific induction of oxidative stress was observed in earthworms; moreover, S-(+)-HEX had a greater influence on the contents of malonaldehyde, cytochrome P450, and 8-hydroxy-2-deoxyguanosine than R-(-)-HEX. These results were consistent with those of the enrichment analysis of differentially expressed genes. The transcriptome sequencing results showed that S-(+)-HEX had a more significant influence on steroid biosynthesis, arachidonic acid metabolism, and cell cycle processes than R-(-)-HEX, leading to abnormal biological function activities. These results indicate that S-(+)-HEX may pose a higher risk to soil organisms than R-(-)-HEX. This study suggests that the environmental risk of chiral pesticides to nontarget organisms should be assessed at the enantiomeric level. (C) 2020 Elsevier Ltd. All rights reserved.

Fluorinated Triazole Foldamers: Folded or Extended Conformational Preferences

Fluorinated peptidomimetic foldamers are still in their infancy. We report here the easy access to fluorinated triazolamers based on 2-amino-3,3,3-trifluoropropyl-1,4-triazolyl acetic acid (CF3-1,4-Tz) and on aminomethyl-1,4-triazolyl-difluoroacetic acid (1,4-Tz-CF2). Both CF3-1,4-Tz and 1,4-Tz-CF2 amino acids were efficiently prepared by copper(I)-catalyzed Huisgen 1,3-dipolar cycloaddition. Their conformational preferences were studied by 2D NMR analyses and molecular dynamic simulations. Foldamers based on CF3-1,4-Tz amino acids are capable of adopting short multi-stranded beta-sheet-like structures that are maintained by electrostatic interactions between the triazole proton and N2 atom of neighboring subunits. On the contrary, foldamers based on 1,4-Tz-CF2 units adopt elongated beta-strand-like structures, stabilized by electrostatic interaction between fluorine atoms and their neighboring protons.

Role of non-conventional hydrogen bonding in controlling regioselectivity for nucleophilic aromatic substitution of 4,6-dinitroisoindoline-1,3-dione with 1,2,3-triazole isomers: a computational studies

The nucleophilic aromatic substitution reactions of 4,6-dinitroisoindoline-1,3-dione with 1,2,3-triazole isomers, i.e., 1H-1,2,3-triazole and 2H-1,2,3-triazole, have been investigated theoretically using DFT/B3LYP calculations employing 6-31G(d,p) basis set in gas phase as well as in solvent phase. The computational studies have supported the formation of transition states via one-step concerted mechanism for the nucleophilic aromatic displacement of nitro groups with 1,2,3-triazoles rather than intermediate formation via two-step addition-elimination mechanism. The amination of 4,6-dinitroisoindoline-1,3-dione with 1,2,3-triazole isomers have revealed regioselectivity of peri-attack despite sterically favorable para-attack. The regioselectivity is attributed to the stabilization of the transition state through intra-molecular hydrogen bond C-H center dot center dot center dot O=C. This work presents the role of C-H bond as an effective hydrogen bond donor. The molecular interactions through hydrogen bonding have been investigated using AIM method. This work shall result in the synthesis of new regioselective 1,2,3-triazole-derived phthalimide compounds possessing potential biological candidature.

Copolymers of Methyl Acrylate and Vinylazoles: Synthesis, Thermolabile Properties, and Grafting of Polyamine Chains

New copolymers of methyl acrylate with 1-vinylimidazole, 1-vinyl-1,2,4-triazole, and 4-vinyl-1,2,3-triazole are synthesized by radical copolymerization. It is shown that the reactivity ratios for methyl acrylate and 1-vinylimidazole are 0.83 +/- 0.09 and 0.25 +/- 0.02, for methyl acrylate and 1-vinyl-1,2,4-triazole are 1.0 +/- 0.04 and 0.27 +/- 0.01, and for methyl acrylate and (4-vinyl-1H-1,2,3-triazolyl)-methyl pivalate are 0.56 +/- 0.03 and 2.90 +/- 0.20, respectively. The behavior of the copolymers in aqueous media and their thermoresponsive properties are studied by potentiometric titration and dynamic light scattering. Copolymer macromolecules occur in aqueous solutions in the form of large associates the fraction of which increases upon heating; in some cases, an insoluble phase is formed. It is found that the copolymers with the grafted oligopropylamine moieties containing N-vinylazole units can interact with the DNA oligonucleotide, stimulating their research as agents for the delivery of nucleic acids to living cells.
