Two energetic compounds, erythritol tetranitrocarbamate (ETNC) and pentaerythritol tetranitrocarbamate (PETNC), and their salts, were synthesized in three steps, characterized and compared. All synthesized compounds were characterized by IR, DSC and multinuclear NMR spectroscopy. Four compounds were further investigated by single crystal X-ray diffraction. All nonmetal salts show extremely low mechanical sensitivity (IS >= 30 J; FS >= 360 N). The heats of formation were calculated using Gaussian 09, and the detonation performances were calculated using EXPLO 5. Although these nonmetal salts are lower than the neutral compounds ETNC (D: 7960 m s(-1), P: 27.4 GPa) and PETNC (D: 7629 m s(-1), P: 24.3 GPa), they possess high detonation performances that are better than TNT. Erythritol-based and corresponding pentaerythritol-based energetic materials were compared in terms of their thermostability, detonation velocity and detonation pressure. They were also compared in their respective series. ETNC and PETNC and their salts have short preparation steps and are easy to isolate in high yields, and thus have promising potential applications as explosives.

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.

Heat stress (HS) has serious effects on plant development, resulting in heavy agricultural losses. A critical transcription factor network is involved in plant adaptation to high temperature. DEHYDRATION RESPONSIVE ELEMENT-BINDING PROTEIN2A (DREB2A) is a key transcription factor that functions in plant thermotolerance. The DREB2A protein is unstable under normal temperature and is degraded by the 26S proteasome; however, the mechanism by which DREB2A protein stability dramatically increases in response to HS remains poorly understood. In this study, we found that the DREB2A protein of Arabidopsis (Arabidopsis thaliana) is stabilized under high temperature by the posttranslational modification SUMOylation. Biochemical data indicated that DREB2A is SUMOylated at K163, a conserved residue adjacent to the negative regulatory domain during HS. SUMOylation of DREB2A suppresses its interaction with BPM2, a ubiquitin ligase component, consequently increasing DREB2A protein stability under high temperature. In addition, analysis of plant heat tolerance and marker gene expression indicated that DREB2A SUMOylation is essential for its function in the HS response. Collectively, our data reveal a role for SUMOylation in the maintenance of DREB2A stability under high temperature, thus improving our understanding of the regulatory mechanisms underlying HS response in plant cells. SUMOylation increases the protein stability of DREB2A, a key transcription factor in the response to heat stress in plant cells.

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.

Phenacylbromide derivatives constitute a multilateral group of precursors for the synthesis of numerous heterocycles of organic compounds. Briefly, 5-(2-bromo-acetyl)-substituted-thiophene derivative has been used as a synthon for synthesis of new thiophene-containing compounds through the reaction with nucleophilic nitrogen compounds and thioamides. The suggested structures of the newly synthesized thiophene compounds were confirmed and assured with different spectroscopic tools and with CHN elemental analysis. Additionally, the antimicrobial activity of these thiophene compounds was recorded to investigate their potency against various types of bacteria and fungi. Results showed that these compounds exhibit significant inhibitory activity against the growth of tested bacterial and fungal strains and that some derivatives were more potent than the employed reference drugs.

We report the photocatalytic property of a novel AgCl loaded carbon nitride (AgCl/g-C3N5) composite was prepared by a simple precipitation route. The brown colored g-C3N5 was synthesized by a nano-hard templating method using 3-amino-1,2,4-triazole precursor. The morphology, crystallinity and optical properties of the AgCl/g-C3N5 composite were characterized using the X-ray diffraction analysis (XRD), transmission electron microscopy (TEM), and diffuse reflectance spectroscopy (UV-DRS) spectroscopy. The rhodamine B (RhB) removal efficiency was reached 96% within 30 min, which could be attributed to the effective formation of a heterojunction and excellent visible light absorption of AgCl by g-C3N5 incorporation.

CC chemokine receptors 2 (CCR2) and 5 (CCR5) are involved in many inflammatory diseases; however, most CCR2 and CCR5 clinical candidates have been unsuccessful. (Pre)clinical evidence suggests that dual CCR2/CCR5 inhibition might be more effective in the treatment of such multifactorial diseases. In this regard, the highly conserved intracellular binding site in chemokine receptors provides a new avenue for the design of multitarget ligands. In this study, we synthesized and evaluated the biological activity of a series of triazolopyrimidinone derivatives in CCR2 and CCR5. Radioligand binding assays first showed that they bind to the intracellular site of CCR2, and in combination with functional assays on CCR5, we explored structure-affinity/activity relationships in both receptors. Although most compounds were CCR2-selective, 39 and 43 inhibited beta-arrestin recruitment in CCR5 with high potency. Moreover, these compounds displayed an insurmountable mechanism of inhibition in both receptors, which holds promise for improved efficacy in inflammatory diseases.

Primary aromatic amines (PAAs), as a class of persistent and highly toxic organic pollutants, have been posing a great threat to human health and the environment. Therefore, the design and preparation of a highly sensitive and selective luminescent probe to detect PAAs among various amines are important but challenging. In this work, by introducing electron-deficient monomer 4,4 ‘-(benzo[c][1,2,5]thiadiazole-4,7-diyl)dibenzaldehyde (BTDD) with an aggregation-caused quenching behavior into the 2D framework, fluorescent ultrathin covalent triazine framework (F-CTF) nanosheets were constructed. Compared with the aggregated BTDD monomer, the obtained F-CTF-3 nanosheet shows much higher fluorescence quantum yield due to the BTDD fragment being well dispersed in the 2D framework. The F-CTF-3 nanosheet exhibits high stability, high porosity, and high fluorescence performance and has a rich electron-deficient unit in the pore channel, making it an ideal platform for sensing electron-rich PAA molecules. In fact, the F-CTF-3 nanosheet shows high sensitivity and selectivity for PAA detection by fluorescence quenching, among various amines, covering some classic aliphatic amines, heterocyclic amines, secondary aromatic amines and tertiary aromatic amines. To the best of our knowledge, it is the first reported fluorescent sensor for selective sensing of PAAs among various amines. Moreover, F-CTF-3 exhibits unprecedented low detection limits of 11.7 and 1.47 nM toward phenylamine (PA) andp-phenylenediamine (PDA), respectively, surpassing all the reported fluorescent sensors. The combination of experimental analysis and density functional theory (DFT) calculations demonstrates that the unique PAA detection performance of F-CTF-3 can be attributed to the static quenching process, which is confirmed by the formation of a ground-state fluorescence-quenched complex on account of the hydrogen bonding interactions between F-CTF-3 and PAAs. This work not only provides a thiadiazole-based 2D fluorescent organic framework nanosheet, but also an excellent fluorescent sensor with unexpected sensitivity and selectivity for PAA detection.
