Surfactant-assisted synthesis of mesoporous hafnium- imidazoledicarboxylic acid hybrids for highly efficient hydrogen transfer of biomass-derived carboxides

Catalytic transfer hydrogenations of biomass-derived carbonyl compounds to produce corresponding alcohols are important pathway for biomass transformation. Herein, a facile route was developed to synthesize the surfactant-assisted heterogeneous acid-base bifunctional 4,5-imidazoledicarboxylic acid-hafnium hybrid catalyst (Hf-H3IDC-T) by hydrothermal self-assembly method. The as-prepared Hf-H3IDC-T was characterized by SEM and TEM, FT-IR spectra, N-2 adsorption-desorption, X-ray diffraction patterns (XRD), X-ray photoelectron spectroscopy (XPS), Thermogravimetry analysis (TG), NH3/CO2-TPD, NMR, GC-MS, ICP-OES and elemental analysis. Hf-H3IDC-T hybrid had mesoporous structure and acid-base couple sites. A quantitative yield (99.2%) of furfuryl alcohol (FFA) was obtained from furfural (FUR) over Hf-H3IDC-T using 2-propanol as the hydrogen source under mild conditions. It’s found that the amino groups on the imidazole ring is beneficial to enhance the base sites of catalyst. Meanwhile, the addition of hexadecyl trimethyl ammonium bromide (CTAB) as template agents can improve the specific surface area of the catalyst. Dynamic analysis showed that the apparent activation energy of FUR reduction was as low as 50.89 kJ / mol. The as-prepared catalyst has good stability and can be recycled. Finally, the catalyst also has a good catalytic effect on the hydrogenation reaction of aldehydes and ketones of biomass-derived compounds.

A metal-free visible light promoted three-component facile synthesis of 4-oxo-tetrahydroindoles in ethanol-water

A mild and efficient visible light-mediated one-pot multicomponent tandem approach to construct 4-oxo-tetrahydroindoles in ethanol-water medium at room temperature has been described. The characteristics of reported methodology are the utilization of visible light, an ideal source of energy to generate C-C and C-N bonds from commercially available substrates namely dimedone, phenacyl bromides, and amines. The presented protocol is highly compatible for developing 4-oxo-tetrahydroindole derivatives with improved selectivity and high yields. Moreover, metal-free synthesis, environmental friendly solvent, easy workup process, high atom economy, cost-effectiveness, short reaction time, and broad substratescope are the major advantages of reported protocol.

FAM225A promotes sorafenib resistance in hepatocarcinoma cells through modulating miR-130a-5p-CCNG1 interaction network

Chemotherapy resistance is still a key hurdle in current hepatocellular carcinoma (HCC) treatment. Therefore, clarifying the molecular mechanisms contributing to this acquired resistance is urgent for the effective treatment of liver cancer. In this research, we observed that lncRNA FAM225A expression is dramatically up-regulated not only in HCC tissues and cell lines but also in sorafenib-resistant HepG2/SOR cells. Moreover, FAM225A knockdown significantly weakened HepG2/SOR cells resistance to sorafenib treatment by MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. Similar results were obtained from the tumor xenograft model in mice. Further mechanistic researches revealed that the direct interaction between FAM225A and miR-130a-5p, while miR-130a-5p negatively modulated Cyclin G1 (CCNG1) expression by targeting 3’UTR of CCNG1. MiR-130a-5p inhibition or CCNG1 overexpression could partially offset FAM225A knockdown-induced increased viability of HepG2/SOR cells in response to sorafenib challenge. Collectively, our findings provide evidence that FAM225A/miR-130a-5p/CCNG1 interaction network regulates the resistance of HCC cells to sorafenib treatment and could supply a possible strategy for restoring sorafenib sensitivity in HCC therapy.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 2067-33-6. Product Details of 2067-33-6.

Trinuclear copper(ii) bromide complex [C3H5N3Br](2n)[Cu3Br8](n). Structure, magnetic properties and DFT calculations

Halidocuprates(ii) show unusual magnetic properties and a high degree of structural flexibility. We present the results of crystallographic, electron paramagnetic resonance (EPR) spectroscopic and magnetochemical analyses of a new [HL](2n)[Cu3Br8](n) compound (HL = 3-amino-4-bromopyrazolium) – the first example of an inorganic polymer built from trimeric [Cu3Br8](2-) units with a 5-membered nitrogen-containing heterocycle as an organic counter ion. The EPR spectrum of the polycrystalline sample exhibited a signal at g approximately equal to 2.06 broadened owing to spin-spin interactions between copper ions. The EPR and magnetochemical data indicate a ferromagnetic intertrimer interaction with Theta = 13 K and an antiferromagnetic intratrimer interaction with J = 310 K between the nearest-neighbor copper(ii) ions, which is in agreement with DFT calculations.

Chitosan Hydrogel Supports Integrity of Ovarian Follicles during In Vitro Culture: A Preliminary of A Novel Biomaterial for Three Dimensional Culture of Ovarian Follicles

Objective: Testing novel biomaterials for the three dimensional (3D) culture of ovarian follicles may ultimately lead to a culture model which can support the integrity of follicles during in vitro culture (IVC). The present study reports the first application of a chitosan (CS) hydrogel in culturing mouse preantral follicles. Materials and Methods: In this interventional experiment study, CS hydrogels with the concentrations of 0.5, 1, and 1.5% were first tested for fourier transform infrared spectroscopy (FT-IR), Compressive Strength, viscosity, degradation, swelling ratio, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) cytotoxicity and live/dead assay. Thereafter, mouse ovarian follicles were encapsulated in optimum concentration of CS (1%) and compared with those in alginate hydrogel. The follicular morphology, quality of matured oocyte and steroid secretion in both CS and alginate were assessed by enzyme-linked immunosorbent assay (ELISA). The expression of folliculogenesis, endocrine, and apoptotic related genes was also evaluated by quantitative real-time polymerase chain reaction (qRT-PCR) and compared with day that in 0. Results: The rates of survival, and diameter of the follicles, secretion of estradiol, normal appearance of meiotic spindle and chromosome alignment were all higher in CS group compared with those in alginate group (P <= 0.05). The expression of Cyp19a1 and Lhcgr in CS group was significantly higher than that of the alginate group (P <= 0.05). Conclusion: The results showed that CS is a permissive hydrogel and has a beneficial effect on encapsulation of ovarian follicle and its further development during 3D culture.

Development of adaptive neuro-fuzzy inference system model for predict trihalomethane formation potential in distribution network simulation test

Trihalomethanes (THMs), which is one of the major classes of DBP known to be highly cytotoxic and genotoxic, were formed and modeled under controlled conditions by laboratory-scale distribution network simulation test. The formation potentials of THM depending on the parameters such as natural organic matter, bromide, chlorine, pH, and contact time were determined. Subsequently, the Adaptive Neuro-Fuzzy Inference System (ANFIS) model was developed using these parameters as inputs and THM formation potentials as output, and the correlation coefficient was 0.9817. In the range of the inputs, the ANFIS model representing the simulation test results were compared with THM formations of an actual distribution network system in dry and wet seasons. As a result, the predictions of the ANFIS model were little affected by the unidentified factors that were not used in model training but are known to affect THM formations in real waters and gave more consistent results than the EPA model.

Evaluation of 3 (4, 5 dimethyl-2-thiazolyl)-2, 5 diphenyl tetrazolium bromide method for rapid detection of vancomycin-resistant enterococci

Vancomycin-resistant enterococci (VRE) have become a global problem of hospital-associated infections. A rapid VRE detection and early isolation of the positive cases are essential for prevention and control of their transmission in hospitals. The aim of this study was to develop and evaluate a simple and rapid method for detection of VRE by using 3 (4, 5 dimethyl-2-thiazolyl)-2, 5 diphenyl tetrazolium bromide (MTT) colorimetric method compared with standard broth microdilution (BMD) and Epsilometer test (Etest). A total of 85 Enterococcus isolates (75 vancomycinnon-susceptible, 2 vancomycin-intermediate and 8 vancomycin-susceptible) were studied. The minimum inhibitory concentrations (MICs) of vancomycin for all isolates were tested by BMD, MTT and Etest methods. The MTT method gave results within 9 h with good category agreement, essential agreement, very major, major, and minor errors (100, 92.9, 0, 0 and 7.1%, respectively), which were comparable to those of the Etest (97.6, 95.3, 2.4, 0 and 4.7%, respectively). The Cohen’s kappa coefficient (kappa) of the MTT method compared with the BMD showed perfect agreement (1.000) (p < 0.001). The MTT method is simple and rapid for early VRE detection to support prevention and control the spread of the enterococci in hospitals.

Design of process for stabilization of La2NiMnO6 nanorods and their magnetic properties

In the present study, we have developed a process to stabilize La2NiMnO6 (LNMO) nanorods via hydrothermal process using cetyl trimethylammonium bromide as a capping agent. One dimensional morphology (nanorods) of LNMO leads to MnO6 octahedral expansion that contributed to the overall expansion in LNMO unit cell. Large shape anisotropy of nanorods carries structural (unit cell) modification in the form of horizontal and vertical tilt of NiO(6 )and MnO6 octahedra along the c axis. Large saturation magnetization M-s is observed for LNMO nanorods as compared to that of their bulk and nanoparticles. X-ray photoelectron spectroscopy (XPS) analysis confirmed the large M-s values observed for nanorods could be attributed to mixed valence states of magnetic ions at B-site (Mn3+, Mn4+, Ni2+, Ni3+). The optical studies of LNMO nanorods shows that the observed band gap (E-g: 1.9 eV) is considerably larger than band gap reported for bulk LMNO (E-g: 1.2-1.4 eV). The enhanced saturation magnetization of nanorods is consistent with a structurally ordered single phase material with very few antisite defects.
