Isotopic multiplets in the carbon-13 NMR spectra of polyols with partially deuterated hydroxyls

Isotopic multiplets in the carbon-13 NMR spectra of polyols with partially deuterated hydroxyls.Some chemicals with cas registry numbers like 6014-42-2 and 6189-71-5 are also used. 2. Effects of cis-trans isomerism in cyclic vicinal diol systems. Reuben, Jacques (Res. Cent., Hercules Inc., Wilmington, DE 19894, USA). J. Am. Chem. Soc., 106(8), 2461-2 (English) 1984. CODEN: JACSAT. ISSN: 0002-7863. DOCUMENT TYPE: Journal CA Section: 33 (Carbohydrates) Section cross-reference(s): 22 In polyols, deuteration of the hydroxyls gives rise to two- and three-bond isotope effects on carbon-13 chem. shifts. In cyclic vicinal diol systems, the magnitude of the three-bond effect depends on the mutual orientation, cis or trans, of the hydroxyls. The effect is larger for the trans configuration. .

Human keratinocyte membrane lectins: characterization and modulation of their expression by cytokines

Human keratinocyte membrane lectins: characterization and modulation of their expression by cytokines. Cerdan, Dominique; Grillon, Catherine; Monsigny, Michel; Redziniak, Gerard; Kieda, Claudine (Cent. Biophys. Mol.In this study， 6014-42-2 and 6696-41-9 are also used., CNRS, Orleans 45071, Fr.). Biol.

DOCUMENT TYPE: Journal CA Section: 15 (Immunochemistry) Section cross-reference(s): 13 In an attempt to identify cell surface mols. involved in recognition phenomena between cells such as keratinocytes and melanocytes and putatively target biol. responses modifiers to keratinocytes, the detection was undertaken of cell surface sugar specific receptors: membrane lectins. Keratinocyte membrane lectins were found to bind synthetic glycoproteins (neoglycoproteins) carrying either a-L-fucosyl or a-L-rhamnosyl residues. Fluorescence microscopy observations indicate that cultured keratinocytes are able to bind these two neoglycoproteins while frozen sections of human skin labeled with neoglycoprotein-coated covaspheres show that the selectivity of the binding to keratinocytes is restricted to a-L-rhamnosyl-BSA. Keratinocytes were adapted to grow on collagen; harvesting conditions allowing the anal. of keratinocytes by flow cytometry are described. This technique allows the quantification of the binding at 4°, and the estn. of the endocytosis of F-, neoglycoproteins: F-, a-L-Rha-BSA and F-, a-L-Fuc-BSA were efficiently internalized. Thereafter, a-L-rhamnose-substituted liposomes contg. 5-(6)carboxyfluorescein were prepd. in order to follow the delivery of the fluorescent dye into cells. This was measured both by flow cytometry and by spectrofluorimetry. The expression of surface lectins was checked upon action of cytokines (IL-1a, IL-1b, IL-2, and TNF) which are known as biol. response modifiers of keratinocytes. .
