Control of glycoside bond stereochem. is the central challenge in the synthesis of oligosaccharides. 2-Deoxyglycosides, which lack a C2 substituent to guide stereoselectivity, are among the most difficult classes of glycoside bond constructions. Here we present a method to synthesize 2-deoxysaccharides with specified glycoside bond stereochem. using a nucleophilic carbohydrate residue and the synthetic equivalent of an alc. electrophile. Because the configuration of the nucleophile can be precisely controlled, both α- and β-glycosides can be synthesized from the same starting material in nearly all cases examined Stereoselectivities in these reactions are often greater than 50:1 and yields typically exceed 70%. This strategy is amenable to the stereocontrolled syntheses of trisaccharide diastereomers, and a tetrasaccharide. This method may be extensible to other classes of carbohydrates.

Yadav, Vishal; Gordon, Jesse B.; Siegler, Maxime A.; Goldberg, David P. published the artcile< Dioxygen-Derived Nonheme Mononuclear FeIII(OH) Complex and Its Reactivity with Carbon Radicals>, Formula: C19H16O, the main research area is neopentylamine dioxygen nonheme mononuclear iron hydroxide preparation reactivity carbon; carbon radical reactivity neopentylamine dioxygen nonheme mononuclear iron hydroxide; crystal mol structure neopentylamine dioxygen nonheme mononuclear iron hydroxide.

A new tetradentate, monoanionic, mixed N/O donor ligand (BNPAPh2O-) with second coordination sphere H-bonding groups has been synthesized for stabilization of a terminal FeIII(OH) complex. The complex FeII(BNPAPh2O)(OTf) (1) reacts with O2 to give a mononuclear terminal FeIII(OH) complex, FeIII(OH)(BNPAPh2O)(OTf) (2), both of which were characterized by x-ray diffraction, electrospray ionization mass spectrometry, UV-vis, 1H and 19F NMR, 57Fe Moessbauer, and ESR spectroscopies. Treatment of 2 with carbon radicals (Ar3C·) gives Ar3COH and the FeII complex 1, in direct analogy with the elusive radical “”rebound”” process proposed for nonheme iron enzymes.

Michel, Olga; Blasiak, Piotr; Saczko, Jolanta; Kulbacka, Julita; Drag-Zalesinska, Malgorzata; Rzechonek, Adam published the artcile< Electropermeabilization of metastatic chondrosarcoma cells from primary cell culture>, Electric Literature of 1492-18-8, the main research area is chondrosarcoma metastasis primary cell culture electropermeabilization; chondrosarcoma; electroporation; lung metastasis; primary cell cultures.

Primary cell cultures are challenging, but reliable model reflecting tumor response in vitro. The study was designed to examine if the increased electropermeabilization can overcame initial drug insensitivity in chondrosarcoma cells from lung metastasis. We established a primary cell culture and evaluated the cytotoxic impact of four drugs-cisplatin (CDDP), camptothecin, 2-methoxyestradiol, and leucovorin calcium (LeuCa). After determination of parameters allowing for electropermeabilization, we performed electrochemotherapy in vitro with the least toxic drugs-CDDP and LeuCa. Although combining CDDP and leucovorin together increased their toxicity and supported apoptosis, application of pulsed elec. fields (PEFs) brought no advantage for their efficacy. The study emphasizes the need for introduction of primary cell cultures into studies on pulse elec. fields as model frequently less sensitive to PEF-based treatments than continuous cell lines.

Tang, Yu; Reddy, D. Prabhakar; Yu, Biao published the artcile< A dehydrative glycosylation protocol mediated by nonafluorobutanesulfonyl fluoride (NfF)>, HPLC of Formula: 4064-06-6, the main research area is stereoselective glycosylation catalyst nonafluorobutanesulfonyl fluoride dehydrative disaccharide glycoside preparation.

A new dehydrative glycosylation protocol that proceeds through selective activation of glycosyl hemiacetals with nonafluorobutanesulfonyl fluoride (NfF) has been disclosed. Contrary to the major classical glycosylation reactions that proceed under acidic or neutral conditions, the present glycosylation reaction proceeds under mild basic conditions. In the absence of an external acceptor, self-condensation of the glycosyl hemiacetal occurs, providing the corresponding sym. 1,1′-disaccharides in high yields.

Surrati, Amal; Evseev, Sergey; Jourdan, Fabien; Kim, Dong-Hyun; Sottile, Virginie published the artcile< Osteogenic response of human mesenchymal stem cells analysed using combined intracellular and extracellular metabolomic monitoring>, Electric Literature of 87-73-0, the main research area is metabolite osteogenesis mesenchymal stem cell; Mesenchymal stem cells; Osteogenesis; Differentiation; Metabolomics; LC-MS; Metabolomics profiling.

The skeleton is a metabolically active organ undergoing continuous remodelling initiated by mesenchymal progenitors present in bone and bone marrow. Under certain pathol. conditions this remodelling balance shifts towards increased resorption resulting in weaker bone microarchitecture, and there is consequently a therapeutic need to identify pathways that could inversely enhance bone formation from stem cells. Metabolomics approaches recently applied to stem cell characterization could help identify new biochem. markers involved in osteogenic differentiation. Combined intra- and extracellular metabolite profiling was performed by liquid chromatog.-mass spectrometry (LC-MS) on human mesenchymal stem cells (MSCs) undergoing osteogenic differentiation in vitro. Using a combination of univariate and multivariate analyses, changes in metabolite and nutrient concentration were monitored in cultures under osteogenic treatment over 10 days. A subset of differentially detected compounds was identified in differentiating cells, suggesting a direct link to metabolic processes involved in osteogenic response. These results highlight new metabolite candidates as potential biomarkers to monitor stem cell differentiation towards the bone lineage.

Liu, Xuegui; Bian, Jun; Li, Danqi; Liu, Changfeng; Xu, Shuangshuang; Zhang, Gongling; Zhang, Lixin; Gao, Pinyi published the artcile< Structural features, antioxidant and acetylcholinesterase inhibitory activities of polysaccharides from stem of Physalis alkekengi L.>, Formula: C6H12O6, the main research area is Physalis stem polysaccharide antioxidant acetylcholinesterase structural property.

Physalis alkekengi L.(P. alkekengi) is an important medicinal plant in China. In this study, two polysaccharides (SPAP-1 and SPAP-2) were isolated from the stem of P. alkekengi using hot water extraction method. The extract was further purified by DEAE-cellulose and Sephadex G-200 chromatog. The chem. characteristics, surface features and thermal stability of SPAP-1 and SPAP-2 were evaluated. For the first time, high-performance liquid chromatog. with refractive index detection and amino column (without sample derivatization) was performed to analyze the monosaccharide composition of polysaccharides obtained from the stem of P. alkekengi. As a result, SPAP-1 (Mw = 9.1 kDa) consisted of rhamnose, arabinose, galacturonic acid, mannose, and glucose in the ratio of 1.0:1.5:1.9:29.1:1.03, while SPAP-2 (Mw = 13.5 kDa) comprised of rhamnose, xylose, arabinose, mannose and glucose in the ratio of 31.8:14.8:1.0:6.5:22.6. Addnl., the antioxidant effects of SPAP-1 and SPAP-2 were evaluated by ferric reducing power, 2,2′-Azinobis-(3-ethylbenzthiazoline-6-sulfonate acid) (ABTS) and 2.2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assays. The results showed that the purified polysaccharides exerted significant scavenging activities. Subsequently, acetylcholinesterase inhibitory effects in vitro of the polysaccharides were investigated, which showed that, SPAP-1 and SPAP-2 showed moderate acetylcholinesterase inhibitory activities. Thus, the polysaccharide content in P. alkekengi stem as promising source of natural products possess good antioxidant activities and may exert beneficial effects on cognitive function.
