Developing highly efficient heterogeneous catalysts for cycloaddition of CO2 and epoxides to produce cyclic carbonates is promising but challenging. In this work, a novel three-dimensional metal organic framework (MOF) with cylinder pore systems and unsaturated Zn sites has been demonstrated as potent candidate in CO2 fixation at mild and solvent-free conditions. The Zn(atz)(bdc)(0.5), where atz = aminotriazole and H(2)bdc = terephthalic, exhibits microporous nature that can regulate the catalytic interaction of active centers and substrates. The structure stability has been systematically investigated and proven to be sufficient for practical application. Furthermore, the cooperative effects of porosity, CO2 binding affinity, activation centers, and synergism with co-catalyst have been deeply investigated. Moreover, high propylene epoxide conversion (97%) and selectivity (> 99%) have been achieved at mild conditions (60 degrees C and 1 MPa) with excellent cycle stability. Owing to the well-defined pore system, an obvious substrates selectivity has been clearly observed. A possible catalytic mechanism has been proposed and verified by DFT calculations. Furthermore, the prepared Zn-MOF can also be used as an efficient heterogeneous catalyst for the reaction of epoxides with alcohols to produce beta-alkoxy alcohol. [GRAPHICS] .

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.

Neutrophil survival and oxidative stress during inflammatory conditions are linked to tissue damage. The present study explores less understood role of catalase, the enzyme catalysing hydrogen peroxide decomposition, in neutrophil survival/death. Importantly, inhibition of catalase activity following S-glutathionylation in the PMA, NO, or zymosan-activated neutrophils or treatment with catalase inhibitor led to neutrophil death. On the contrary, introducing reducing environment by TCEP rescued catalase activity and significantly improved neutrophil survival. Furthermore, augmentation in ROS generation by NOX-2 activation or induction of mitochondrial ROS by Antimycin-A induced catalase S-glutathionylation and cell death, which was prevented in the neutrophil cytosolic factor1 (NCF-1-/-) cells or was rescued by MitoTEMPO, a mitochondrial ROS scavenger, thus, suggesting a correlation between catalase S-glutathionylation/activity inhibition and reduced neutrophil survival. Altogether, enhanced NOX2 activation/mitochondrial dysfunction led to reduced survival of human and mice neutrophils, due to H2O2 accumulation, S-glutathionylation of catalase, and reduction in its enzymatic activity. The present study thus demonstrated mitigation of catalase activity under oxidative stress-impacted neutrophil survival.

A new energetic coordination polymer (ECP) composite, namely GO-Cu(II)-AmTZ, has been synthesized by 3-amino-1,2,4-triazole (AmTZ) and multifunctional graphene oxide (GO) coordination with Cu(II) successively. The ECP composite was further characterized through SEM, EDS and XPS analysis as well as FTIR and Raman spectroscopy. It shows high thermostability, high decomposition heat release and insensitivity to mechanical stimuli. What’s more, thermal analysis data for ammonium perchlorate (AP) have been obtained by mechanically mixing GO-Cu(II)-AmTZ and AP. The low-temperature decomposition (LTD, 335.3 degrees C) and high-temperature decomposition (HTD, 441.3 degrees C) peaks of AP were reduced to an exothermic peak at 298.4 degrees C at a heating rate of 10 degrees C min(-1). GO-Cu(II)-AmTZ exhibits outstanding catalytic performance by decreasing the activation energy from 168.7 kJ mol(-1) to 122.4 kJ mol(-1), indicating its promising application as a combustion catalyst for improving the thermal-catalytic decomposition performance of energetic materials largely. In addition, thermal analysis techniques including thermogravimetry coupled with mass spectrometry (TG/MS) and thermogravimetry coupled with infrared spectrometry (TG/IR) were employed to determine the decomposition mechanisms.

Based on the previous studies that revealed the valuable role of pyrazole scaffold in cancer management and VEGFR-2 inhibition, a new set of pyrazole conjugated with pyrazoline, triazolopyrimidine and pyrazolone moieties were synthesized and investigated for their anticancer efficiency against human breast cancer MCF-7. The anticancer screening revealed the significant sensitivity of breast carcinoma towards compounds 4b, 5c, 6c, 7b, 7c and 12c with IC50 values ranging from 16.50 – 26.73 mu M in comparison with tamoxifen (IC50 = 23.31 mu M). Moreover, the new analogues were further examined for their VEGFR-2 inhibitory activity, among the tested derivatives 5c, 6c, 7b, 7c and 12c displayed prominent inhibitory efficiency versus VEGFR-2 kinase with % inhibition ranging from 70 to 79%. Compounds 6c, 7c and 12c revealed inhibitory efficiency in nanomolar level with IC50 (913.51, 225.17 and 828.23 nM, respectively) comparing to sorafenib (IC50 = 186.54 nM). Flow cytometric analysis revealed that the promising compound 12c prompted pre-G1 apoptosis and cell growth cessation at G2/M phase and stimulated apoptosis via activation of caspase-3. Moreover, molecular docking study of the promising derivatives was performed to highlight their binding modes and interactions with the amino acid residues of VEGFR-2 enzyme.

Oxidative stress biomarkers are powerful endpoints in toxicological research. Cellular reductive/oxidative balance affects numerous signaling pathways involving H2O2. Detoxification and control of H2O2 levels results mainly from catalase activity. The aim of this work was to develop a precise, simple, cost-effective microassay to measure catalase activity in small tissue samples and cell extracts. We developed a protocol that quantifies H2O2 decomposition by intrinsic catalase in biological samples. Catalase activity was calculated based on rate of decomposition of H2O2, following absorbance at 240 nm. We developed a multi-well spectroscopic approach, reducing sample quantity requirements and allowing simultaneous assessment of large number of samples. The protocol is sensitive across a wide range of catalase activity (11.5-7575 U). The assay presents a 95% confidence interval with an intra-assay coefficient of variation of 3.7%, an inter-assay coefficient of variation of 6.2% and good correlation with a commercial kit. The assay was established and validated for different biological samples, including sheep hepatic tissue and human tumor and non-tumor cell lines. This high-throughput method is robust, sensitive, time-saving and cost-effective, generating highly reproducible results with precision and good correlation with a commercial kit reinforcing the method’s validity for research and toxicological applications.

Herein, Fe3O4 nano-particles are anchored over nitrogen doped reduced graphene oxide Fe3O4@N-rGO) structure to accommodate electric and magnetic components, so that it could match both the conduction and polarization loss to augment the attenuation of electromagnetic radiation. The formation of condensed heteroaromatic structure and decoration of Fe3O4 particles on r-GO structure are confirmed by photoelectron spectroscopy (XPS). high-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD). The Fe3O4@N-rGO hybrid is subsequently dispersed in epoxy matrix, which result in significantly higher electrical conductivity (1.31 s/m) and electromagnetic interference (EMI) shielding efficiency (- 26 dB at 1 mm thickness). It was assumed that presence of electric-magnetic integrated Fe3O4@N-rGO hybrid in epoxy matrix significantly improved the interfacial polarization and anisotropy energy, which was reflected in absorption loss value of -27 dB. The composites also exhibited enhanced mechanical and thermo-mechanical properties coupled with improved thermal stability.
