Synthesis of Benzyl 2-Deoxy-C-Glycosides

A synthetic method for benzyl 2-deoxy-C-glycosides has been developed. Palladium-catalyzed benzyl C-glycosylation of TIPS-protected 1-tributylstannyl glycals with a variety of benzyl bromides provided protected benzyl C-glycals. In this reaction, the use of PdCl2 (dppe) promoted a clean reaction, whereas the reaction was accelerated by the addition of Na2CO3. The subsequent transformations provided a novel class of benzyl 2-deoxy-C-glycosides.

Highly Regioselective 5-endo-tet Cyclization of 3,4-Epoxy Amines into 3-Hydroxypyrrolidines Catalyzed by La(OTf)(3)

Highly regioselective intramolecular aminolysis of 3,4-epoxy amines has been achieved. Key features of this reaction are (1) chemoselective activation of epoxides in the presence of unprotected aliphatic amines in the same molecules by a La(OTf)(3) catalyst and (2) excellent regioselectivity for anti-Baldwin 5-endo-tet cyclization. This reaction affords 3-hydroxy-2-alkylpyrrolidines stereospecifically in high yields. DFT calculations revealed that the regioselectivity might be attributed to distortion energies of epoxy amine substrates. The use of this reaction was demonstrated by the first enantioselective synthesis of an antispasmodic agent prifinium bromide.

Wafer-Scale Diisopropylammonium Bromide Films for Low-Power Lateral Organic Ferroelectric Capacitors

Organic ferroelectrics, particularly the polymer polyvinylidene fluoride and its copolymer polyvinylidene fluoride-trifluoroethylene, have received much attention owing to their low cost, flexibility, and convenient thin film fabrication. However, development of this outstanding material for electronic applications is significantly impeded by its attributes of large coercive electric fields and poor spontaneous polarization. While the recent breakthroughs reveal that several kinds of molecular ferroelectrics (e.g., diisopropylammonium bromide (DIPAB)) can exhibit excellent properties comparable to inorganic ferroelectrics, it is still difficult to obtain high-quality continuous thin films for ferroelectric devices with high performance. In this work, a simple solution strategy is used for the preparation of large-area high crystallinity or even single-crystal DIPAB films. Subsequently, planar ferroelectric capacitors are developed with large in-plane ferroelectric polarization. These capacitors possess excellent memory function with small operating voltages (1-3 V), and a record remnant polarization of 13 mu C cm(-2) for organic ferroelectric devices. The findings have the potential to pave the way for the substitution of conventional ferroelectric polymers with DIPAB films for future organic ferroelectric devices.

Design and Fabrication of Anionic/Cationic Surfactant Foams Stabilized by Lignin-Cellulose Nanofibrils for Enhanced Oil Recovery

It has been decades since foams were adapted in further developing water-flooded oilfields. Foam stability is regarded as the governing factor that directly determines the enhanced oil recovery (EOR) efficiency of a foam injection. In this paper, we focus on a series of anionic surfactant-based foaming agent [sodium dodecyl sulfate (SDS)] and non-ionic surfactant-based foaming agent [alkyl polyglycoside (APG)] stabilized by lignin-cellulose nanofibrils (LCNFs), in the absence or presence of a cationic surfactant [hexadecyltrimethylammonium bromide (CTAB)]. Particular attention was placed on the proportion of LCNFs/SDS/CTAB and LCNFs/APG/CTAB as well as their synergism assessment, including foamability, drainage half-time, foam decay, surface tension, and micromorphology. Our results demonstrate that the synergism between cationic/anionic surfactants and LCNFs retarded film drainage and, thus, produced robust foams. The synergism mechanism, contributed to the electrostatic reaction and hydrogen bond between LCNFs and the surfactants, has been discussed and proposed.

Evaluation of Anticancer Activity and Apoptosis inducing ability of Suaeda monoica on Breast Cancer Cell Line

Breast cancer is the most frequently diagnosed cancer in women but rarely found in men. It is an invasive tumor majorly formed in lobules or ducts of the breast. The present study investigates the anticancer activity of Suaeda monoica with different solvent extracts against estrogen receptor-positive MCF-7 using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (M) assay. The different solvents used for this study were ethanol, methanol, acetone and diethyl ether. The diethyl ether extract of the plant showed the highest anticancer activity with an IC50 value of 186.78 mu g/ml in comparison with other solvent extracts. The morphological changes were then observed under an inverted phase-contrast microscope. Fluorescence imaging using propidium iodide stain was done to confirm the changes associated with apoptosis. The study shows that the plant has appreciable anticancer activity against the MCF-7 cell line and further the bioactive compound responsible for the anticancer activity should be isolated and purified.

Immunomodulatory effects of flavonoids: An experimental study on natural-killer-cell-mediated cytotoxicity against lung cancer and cytotoxic granule secretion profile

Background: A new approach involving immune-cell-mediated cancer therapy has been adopted extensively for the sake of lung cancer treatments by utilizing natural killer (NK) cells. NK cell activity can be enhanced with certain agents, and among them are flavonoids. Thus, this study was conducted to investigate the immunomodulatory roles of apigenin, luteolin and quercetin on NK cell activity against lung cancer cells and on the secretions of perforin and granulysin profile. Methods: The NK-92 cells were grown in complete alpha-Minimum Essential Medium (MEM). NCI-H460 lung cancer cells were cultured in Roswell Park Memorial Institute 1640 media. NK cell activity against lung cancer cells were done using MTT(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. The secretions of perforin and granulysin profiles were then analysed using enzyme-linked immunosorbent assay. Results: Apigenin, luteolin and quercetin significantly increased the NK-cell-mediated cytotoxic activity against lung cancer cells at concentrations 12.5 mu g/ml and 25 mu g/ml (P < 0.001). The secretion levels of perforin and granulysin from NK cells were also significantly enhanced with apigenin and luteolin treatment but not with quercetin. Conclusions: All three flavonoid compounds possessed some significant immunomodulatory actions on NK cell cytotoxic activity and granule secretion profiles towards lung cancer therapy.

From Proteomics to Personalized Medicine: The Importance of Isoflavone Dose and Estrogen Receptor Status in Breast Cancer Cells

Continuing efforts are directed towards finding alternative breast cancer chemotherapeutics, with improved safety and efficacy profiles. Soy isoflavones represent promising agents but, despite extensive research, limited information exists regarding their impact on the breast cancer cell proteome. The purpose of this study was to compare the proteomic profiles of MCF-7 (estrogen responsive) and MDA-MB-231 (estrogen non-responsive) breast cancer cells exposed to different concentrations of genistein, daidzein, and a soy seed extract, using a high throughput LC-UDMSE protein profiling approach. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay confirmed the dual activity of soy isoflavones on MCF-7 cells and the inhibitory effect on MDA-MB-231 cells. Proteome profiling of paramagnetic beads prepared peptides by nano-LC UDMSE and pathway enrichment analysis revealed that isoflavones affected distinct molecular pathways in MCF-7 and MDA-MB-231 cells, such as tyrosine kinases signaling pathway, cytoskeleton organization, lipid and phospholipid catabolism, extracellular matrix degradation and mRNA splicing. Also, in MCF-7 cells, low and high isoflavone doses induced different changes of the proteome, including cell cycle alterations. Therefore, the expression of estrogen receptors and the isoflavone dose are determinant factors for the molecular impact of isoflavones and must be taken into account when considering adjuvant breast cancer therapy towards personalized medicine.

Combined experimental and theoretical investigations of Ba3GaS4I: interesting structural transformation originated from halogen substitution

Inorganic chalcohalides have emerged as promising functional materials for a range of applications. However, most of them are chlorides and bromides, while iodides are still rare. Herein, a new quaternary iodine-based chalcohalide Ba3GaS4I has been acquired by the reaction of BaS, Ga, S and BaI2 at 1173 K. Single-crystal XRD analysis reveals that Ba3GaS4I has a centrosymmetric structure (orthorhombic, space group Cmcm, a = 6.991(3) angstrom, b = 15.910(7) angstrom, c = 9.698(4) angstrom, V = 1078.6(7) angstrom(3), and Z = 4) and consists of isolated [GaS4] tetrahedra with charge-balanced Ba2+ cations and I- anions. Ba3GaS4I can be regarded as the product of chemical substitution of Ba3GaS4X (X = Cl, Br), which adopts a different space group, Pnma. The influences of the halogen elements on the bandgap and birefringence have been discussed through first principles calculations and structural comparison.

Radial basis function artificial neural network (RBF ANN) as well as the hybrid method of RBF ANN and grey relational analysis able to well predict trihalomethanes levels in tap water

Many models have been developed in previous studies for predicting the formation of disinfection by-products (DBPs) in drinking water. However, most of them were linear or log-linear regression models, and generated based on simulated disinfection of source water or treated water in a laboratory other than real tap water, which shows low application potential in practice. In this study, a radial basis function artificial neural network (RBF ANN) as well as the hybrid method of RBF ANN and grey relational analysis (GRA) was proposed to predict trihalomethanes (THMs) levels in real distribution systems. A total of 64 sets of data including THM5 levels (trichloromethane (TCM), bromodichloromethane (BDCM) and total-THMs (T-THMs)) and 8 water quality parameters (temperature, pH, UV absorbance at 254 (UVA(254)), dissolved organic carbon, bromide, residual free chlorine, nitrite and ammonia) were used to train and verify the proposed model. As compared to linear and log-linear regression models (r(p) = 0.254-0.659; N-25 = 46-78%), RBF ANN5 for THM5 (TCM, BDCM and T-THMs) prediction consistently show higher regression coefficients (r(p) = 0.760-0.925) and prediction accuracy (N-25 = 92-98%), which indicates the high capability of RBF ANN to learn the complex non-linear relationships involved THM5 formation. Further analysis shows that RBF ANN5 using fewer water quality parameters based on GRA still make excellent performance in THM5 prediction (r(p) = 0.760-0.946; N-25 = 92-98%). This result demonstrates that GRA can be an effective technique to facilitate the generation of sound RBF ANN models with fewer factors.
