Control of glycoprotein synthesis. Characterization of (1->4)-N-acetyl-beta-D-glucosaminyltransferases acting on the alpha-D-(1->3)- and alpha-D-(1->6)-linked arms of N-linked oligosaccharides

Hen oviduct membranes contain at least three N-acetyl-beta-D-glucosaminyltransferases (GlcNAc-T) that attach a betaGlcNAc residue in (1-4)-linkage to a D-Manp residue of the N-linked oligosaccharide core, i.e., (1->4)-beta-D-GlcNAc-T III which adds a “bisecting ” GlcNAc group to form the beta-D-GlcpNAc-(1->4)-beta-D-Manp-(1->4)-D-GlcNAc moiety: (1->2)-beta-D-GlcNAc-T IV which adds a GlcNAc group to the (1->3)-alpha-D-Man arm to form the beta-D-GlcpNAc-(1->4)-2)>-alpha-D-Manp-(1->3)-beta-D-Manp-(1->4)-D-GlcpNAc component; and (1->4)-beta-D-GlcNAc-T VI which adds a GlcNAc group to the alpha-D-Manp residue of beta-D-GlcpNAc-(1->6)-2)>-alpha-D-Manp-R to form beta-D-GlcpNAc-(1->6)-4)>-2)>-alpha-D-Manp-R.We now report a novel (1->4)-beta-D-GlcNAc-T activity (GlcNAc-T VI’) in hen oviduct membranes that transfers GlcNAc to beta-D-GlcpNAc-(1->2)-alpha-D-Manp-(1->6)-beta-D-Manp-R to form beta-D-GlcpNAc-(1->4)-2)>-alpha-D-Manp-(1->6)-beta-D-Manp-R.The structure of the enzyme product was confirmed by 1H NMR spectroscopy.FAB-mass spectrometry and methylation analysis.Previous work with GlcNAc-T IV was carried out with biantennary substrates; we now show that hen oviduct membrane GlcNAc-T IV can also transfer GlcNAc to monoantennary beta-D-GlcpNAc-(1->2)-alpha-D-Manp-(1->3)-beta-D-Manp-R to form beta-D-GlcpNAc-(1->4)-2)>-alpha-D-Man-p-(1->3)-beta-D-Manp-R.The findings that GlcNAc-T VI’and IV have similar kinetic characteristics and that hen oviduct membranes can convert methyl beta-D-GlcpNAc-(1->2)-alpha-D-Manp to methyl beta-D-GlcpNAc-(1->4)-2)>-alpha-D-Manp suggest that these two activities may be due to the same enzyme.The R-group of the beta-D-GlcpNAc-(1->2)-alpha-D-Manp-(1->6)-beta-D-Manp (or Glcp)-R substrate has an important influence on GlcNAc-T VI’enzyme activity.When R is GlcNAc or betaGlc-ally, the activity is drastically reduced.This may be due to conformational factors and may explain why hen oviduct membranes add a GlcNAc residue in (1->4)-beta-linkage mainly to the (1->3)-alpha-D-Man arm of the bi-antennary substrate beta-D-GlcpNAc-(1->2)-alpha-D-Manp-(1->6)-2)-alpha-D-Manp-(1->3)>-beta-D-Manp-R to form beta-D-GlcpNAc-(1->2)-alpha-D-Manp-(1->6)-2)-4)>-alpha-D-Manp-(1->3)>-beta-D-Manp-R.

Studies in solution and the solid state of coordination compounds derived from LiBH4, NaBH4, and bidentate aromatic amines

The mixture of 2, 2?-bipyridylamine, 2, 2?’-bipyridine, 1, 10phenanthroline, 1, 2-phenylendiamine, and 1, 4-phenylendiamine each with LiBH4 and NaBH4 in a 1:1 molar ratio in THF yields seven new complexes of the type MBH4-L-THF and one complex of the type MBH4-L. These compounds were characterized by IR and NMR spectroscopy and X-ray single-crystal structure determinations. In the solid state, the [BH4]- group is bidentate, as deduced from the stretching patterns observed in IR spectra and confirmed by X-ray single-crystal structure analysis. NMR spectroscopy showed that all amines act as bidentate ligands and are symmetrically coordinated to the metal cation. Complexes LiBH4-2, 2?bipyridine-THF (1), NaBH4-2, 2?-bipyridine-THF (2), LiBH4-1,10-phenanthroline-THF (3), and NaBH4- 1,10-phenanthroline-THF (4) have a discrete molecular structure, whereas the complexes LiBH4-1,2-phenylendiamine-THF (5), NaBH4-1, 2-phenylendiamine-THF (6), LiBH4-2, 2?-dipyridilamine (7), and LiBH4- 1, 4-phenylendiamine-THF (8) have polymeric structures in the solid state. N-borane-dipyridylamlne adduct 9 was isolated from, an aged, solution of 7. IR spectroscopy of the new complexes showed that the structures of complexes 1, 3, 4, and 6 are maintained in the solid state and in solution. A rotational barrier for the [BH4]- group of less than 38 KJ mol-1 was estimated for some of the new complexes.

6-O-benzyl- and 6-O-silyl-N-acetyl-2-amino-2-N,3-O-carbonyl-2- deoxyglucosides: Effective glycosyl acceptors in the glucosamine 4-OH series. Effect of anomeric stereochemistry on the removal of the oxazolidinone group

(Chemical Equation Presented) The 4-OH groups of both alpha- and beta-methyl glycosides of N-acetylglucosamine, protected with an oxazolidinone spanning the nitrogen and O-3, and bearing benzyl or silyl protection on O-6, show excellent reactivity as acceptors in couplings to a range of glycosyl donors. The enhanced reactivity of these acceptors is attributed in part to the tied back nature of the oxazolidinone, which reduces hindrance around the nucleophilic oxygen. The N-acetyloxazolidinone function also reduces the tendency seen in simple N-acetylglucosamines toward amide glycosylation, and removes the possibility of problematic hydrogen bonding networks. In the beta-, but not the alpha-, series selective hydrolysis of the N-acetyloxazolidinone directly to the N-acetylglucosamine was possible with barium hydroxide, a feature attributed to chelate formation between the acetamide carbonyl group and the glycosidic oxygen in the beta-series.

Glucose uptake enhancing activity of puerarin and the role of C-glucoside suggested from activity of related compounds

Chemical treatment of diabetes mellitus is widely studied and controlling of blood glucose level is the main course of therapy. In type 2 diabetes mellitus, insulin resistance is the major problem. An isoflavone C-glucoside, puerarin (1), is known to enhance glucose uptake into the insulin sensitive cell and is thought to be a candidate for treatment of diabetes mellitus. We synthesized 1 and several derivatives to apply for the structure-activity relationship study. The result against 3T3-L1 adipocyte indicated that the C-glucoside part of 1 is unconcerned in its activity when tested in vitro and the main structure responsible for its activity was the isoflavone moiety.
