Structural aspects of some 2:1 dipyridylamine complexes of some copper(II) salts: An interesting new polymorph of the binuclear carbonate/perchlorate tetrahydrate adduct

Recent work has described the structural characterization of the complexes Cu2 (C O3) X2?:dpyam:H2O (1:4:4), X? = ClO4, BF4, ‘dpyam’ = dipyridylamine, as a pair of triclinic Z = 1 isomorphs, the cations being modelled in terms of pairs of copper atoms bridged by a carbonate ion disordered about a crystallographic inversion centre. This work has been revisited in the course of describing a new polymorph of the perchlorate in a triclinic cell of twice the size, in which the carbonate unit, now non-disordered, bridges a pair of crystallographically independent copper atoms which display distinctly different coordination environments, one close to the square-pyramidal norm, the other not. Studies of adducts of the form [(dpyam)2CuX]X?(¡¤nH2O) are also recorded. The X/X? = propionate/iodide adduct is found to be isomorphous with its acetate/BF4 but, interestingly, not its propionate/Cl counterpart. ‘Low’-temperature redeterminations of the NCO/Cl ¡¤ 4H2O and nitrite/ClO4 adducts are also recorded, enabling definition of the hydrogen-bonding scheme in the former.

Comparison of differential flavor metabolites in meat of Lubei white goat, jining gray goat and boer goat

Flavor is one of the most important sensory characteristics of meat. The development of taste and aroma can be attributed to thousands of flavor molecules and precursors that are present in meat tissues. As a result, the identification of these flavor compounds and an improved understanding of their roles are necessary for improving the sensory quality and customer appeal of meat products. In the current study, we compared the metabolic profiles of meat specimens from the Lubei white goats (LBB), Boer goats (BE) and Jining grey goats (JNQ) by untargeted liquid chromatography-mass spectrometry. Our metabolomic data revealed that the three types of goat meat showed significantly different profiles of fatty acids, aldehydes, ketones, lactones, alkaloids, flavonoids, phenolics and drug residues, which could underpin the nuances of their flavors. Taken together, our results provided insights into the molecular basis for sensory variations between different goat meat products.

Thioglycosides Are Efficient Metabolic Decoys of Glycosylation that Reduce Selectin Dependent Leukocyte Adhesion

Small-molecule inhibitors of glycosylation can be applied in basic science studies, and clinical investigations as anti-inflammatory, anti-metastatic, and anti-viral therapies. This article demonstrates that thioglycosides represent a class of potent metabolic decoys that resist hydrolysis, and block E-selectin-dependent leukocyte adhesion in models of inflammation. Metabolic decoys are synthetic analogs of naturally occurring biosynthetic acceptors. These compounds divert cellular biosynthetic pathways by acting as artificial substrates that usurp the activity of natural enzymes. While O-linked glycosides are common, they are only partially effective even at millimolar concentrations. In contrast, we report that N-acetylglucosamine (GlcNAc) incorporated into various thioglycosides robustly truncate cell surface N- and O-linked glycan biosynthesis at 10?100 muM concentrations. The >10-fold greater inhibition is in part due to the resistance of thioglycosides to hydrolysis by intracellular hexosaminidases. The thioglycosides reduce beta-galactose incorporation into lactosamine chains, cell surface sialyl Lewis-X expression, and leukocyte rolling on selectin substrates including inflamed endothelial cells under fluid shear. Treatment of granulocytes with thioglycosides prior to infusion into mouse inhibited neutrophil homing to sites of acute inflammation and bone marrow by ?80%?90%. Overall, thioglycosides represent an easy to synthesize class of efficient metabolic inhibitors or decoys. They reduce N-/O-linked glycan biosynthesis and inflammatory leukocyte accumulation.

Fucosylation of chitooligosaccharides by human alpha1,6-fucosyltransferase requires a nonreducing terminal chitotriose unit as a minimal structure

FUT8, a eukaryotic alpha1,6-fucosyltransferase, catalyzes the transfer of a fucosyl residue from guanine nucleotide diphosphate-beta-L-fucose to the innermost GlcNAc of an asparagine-linked oligosaccharide (N-glycan). The catalytic domain of FUT8 is structurally similar to that of NodZ, a bacterial alpha1,6-fucosyltransferase, which acts on a chitooligosaccharide in the synthesis of Nod factor. While the substrate specificities for the nucleotide sugar and the N-glycan have been determined, it is not known whether FUT8 is able to fucosylate other sugar chains such as chitooligosaccharides. The present study was conducted to investigate the action of FUT8 on chitooligosaccharides that are not generally thought to be a substrate in mammals, and the results indicate that FUT8 is able to fucosylate such structures in a manner comparable to NodZ. Surprisingly, structural analyses of the fucosylated products by high performance liquid chromatography, mass spectrometry and nuclear magnetic resonance indicated that FUT8 does not utilize the reducing terminal GlcNAc for fucose transfer but shows a preference for the third GlcNAc residue from the nonreducing terminus of the acceptor. These findings suggest that FUT8 catalyzes the fucosylation of chitooligosaccharide analogous to NodZ, but that a nonreducing terminal chitotriose structure is required for the reaction. The substrate recognition by which FUT8 selects the position to fucosylate might be distinct from that for NodZ and could be due to structural factor requirements which are inherent in FUT8.

HF-Induced Intramolecular C-Arylation and C-Alkylation/Fluorination of 2-Aminoglycopyranoses

Internal C-aryl and C-alkyl glycosides derived from 2-aminoglycopyranoses have been synthesized, exploiting a HF-mediated stereoselective intramolecular glycosylation. These conditions are compatible with acetate protecting groups and allow introduction of aromatics with various electronic distributions at the anomeric position. This strategy also provides straightforward entry to original fluorinated sugar-azacycle hybrids via a tandem internal C-glycosylation/fluorination reaction starting from 2-N-allyl/propargyl glycopyranoses. All cyclizations proceed in a 1,2-cis stereocontrolled manner.
