Making the switch: Compounds 1 and 2 are used as metabolic markers for NMR detection. When neuronal cells switch to a glycolytic state, an uneven distribution of 13C in the N-acetyl group results, thus giving a mixture of the metabolites 1 and 2. It is therefore possible to monitor flux through different metabolic pathways, such as glycolysis, the tricarboxylic acid cycle, and the hexosamine biosynthetic pathway, using a single molecule.

GSK2981278A (1) is a RORgammainverse agonist used as a potential topical nonsteroidal therapy for psoriasis. New synthesis of 1 was developed based on a SNAr reaction of (tetrahydro-2H-pyran-4-yl)methanol with an aryl halide intermediate, prepared from 2-halobenzoic acids. The dianion underwent in situ N,O-bis-isobutylation, followed by a reduction to provide 1. The new route eliminated a genotoxic tosylate of (tetrahydro-2H-pyran-4-yl)methanol and a difficult reductive amination from the original synthesis starting from methyl salicylate. A primary version of the route has been scaled up to deliver 125 kg of 1. However, the heating of a strong base in DMSO for an extended period during the bis-alkylation was found to be a safety concern for manufacturing. A safer and greener process was then developed utilizing a facile N,O-bis-alkylation, which was conducted under phase transfer conditions with mild bases such as potassium carbonate and in green solvents such as water. The concise four stage sequence from 2-halobenzoic acids to GSK2981278A (1) had an overall yield of 41%.

A general and robust method for the incorporation of aspartates with a thioacid side chain into peptides has been developed. Pseudoproline tripeptides served as building blocks for the efficient fluorenylmethyloxycarbonyl (Fmoc) solid-phase synthesis of thioacid-containing peptides. These peptides were readily converted to complex N-glycopeptides by using a fast and chemoselective one-pot deprotection/ligation procedure. Furthermore, a novel side reaction that can lead to site-selective peptide cleavage using thioacids (CUT) was discovered and studied in detail.

Chemistry involves the study of all things chemical – chemical processes, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations.14215-68-0, Name is N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide, molecular formula is C8H15NO6.

The kinetics of hydrolysis in concentrated hydrochloric acid (12.07 M) of the fully N-acetylated chitin tetramer (GlcNAc4) and the fully N-deacetylated chitosan tetramer (GlcN4) were followed by determining the amounts of the lower DP oligomers as a function of time. A theoretical model was developed to simulate the kinetics of hydrolysis of the three different glycosidic linkages in the tetramers. The model uses two different rate constants for the hydrolysis of the glycosidic bonds in the oligomers, assuming that the glycosidic bond next to one of the end residues are hydrolysed faster than the two other glycosidic linkages. The two rate constants were estimated by fitting model data to experimental results. The results show that the hydrolysis of the tetramers is a nonrandom process as the glycosidic bonds next to one of the end residues are hydrolysed 2.5 and 2.0 times faster as compared to the other glycosidic linkages in the fully N-acetylated and fully N-deacetylated tetramer, respectively. From previous results on other oligomers and the reaction mechanism, it is likely that the glycosidic bond that is hydrolysed fastest is the one next to the nonreducing end. The absolute values for the rate constants for the hydrolysis of the glycosidic linkages in GlcNAc4 were found to be 50 times higher as compared to the glycosidic linkages in GlcN4, due to the catalytic role of the N-acetyl group and the presence of the positively charged amino-group on the N-deacetylated sugar residue.

The Amadori rearrangement was investigated as a potential method for the conjugation of carbohydrate moieties to suitable amino components. Starting from selected aldoheptoses, which are readily available by means of the Kiliani-Fischer C-elongation reaction of the corresponding aldohexoses, glycoconjugates presenting D-gluco, D-manno and D-galacto as well as GlcNAc motifs have been synthesised. Following this strategy, non-natural C-glycosyl type glycoconjugates, which can be utilised as building blocks for the composition of larger molecular constructions, are available by a very short synthetic approach.

A rat monoclonal antibody 9D4 raised against the cell surface N-glycan of the parasite Trichinella spirallis protects rats against further infection. The terminal disaccharide beta-d-Tyvp(1?3)beta-d-GalNAcp (2) represents the immunodominant portion of the antigenic determinant. Chemical mapping of the antibody binding site by functional group modification employing monodeoxy and mono-O-methyl congeners identified key polar contacts and topography of the bound disaccharide. We report here a comparison of the chemical mapping studies with the antigen topography inferred from saturation transfer difference (STD) NMR experiments. During chemical mapping several congeners of compound 2 showed substantially enhanced binding. Pairing of these functional group modifications to create derivatives 6 and 7 did not show additive free energy gains and STD NMR data point to small variations in mode of binding as a probable cause. Improved syntheses of disaccharides 2-7 are reported.

Profiling of metabolites is a rapidly expanding area of research for resolving metabolic pathways. Metabolic fingerprinting in medicinally important plants is critical to establishing the quality of herbal medicines. In the present study, metabolic profiling of crude extracts of leaf and root of Withania somnifera (Ashwagandha), an important medicinal plant of Indian system of medicine (ISM) was carried out using NMR and chromatographic (HPLC and GC-MS) techniques. A total of 62 major and minor primary and secondary metabolites from leaves and 48 from roots were unambiguously identified. Twenty-nine of these were common to the two tissues. These included fatty acids, organic acids, amino acids, sugars and sterol based compounds. Eleven bioactive sterol-lactone molecules were also identified. Twenty-seven of the identified metabolites were quantified. Highly significant qualitative and quantitative differences were noticed between the leaf and root tissues, particularly with respect to the secondary metabolites.

A novel acceptor substrate for galactosyltransferase was synthesized containing GlcNAcalpha-pyrophosphate, covalently bound to a hydrophobic phenoxyundecyl moiety (GlcNAc alpha-O-PO3-PO3-(CH 2)11-O-Phenyl). The new substrate was used to develop an assay for a galactosyltransferase activity from Escherichia coli strain VW187 that is involved in lipopolysaccharide synthesis and has not been studied by others. We showed that Gal was transferred from UDP-Gal to the novel acceptor substrate. This was a significant improvement over our previous preliminary assays of the enzyme using endogenous substrate, and showed that these synthetic substrates are useful for assaying enzymes that utilize lipid-bound substrates in O-chain synthesis in Gram-negative bacteria.

Alkaline metalloendopeptidase (metalloprotease) AP1 (48 kDa) from Vibrio sp. isolated from the intestine of a five-barred goatfish (Parupeneus trifasciatus) was reported in our previous paper to produce AP2 (36 kDa) by releasing a peptide fragment (molecular mass of about 12 kDa) from the C-terminal end of AP1 by autodigestion.1) AP1 strongly agglutinated fish (flounder, Paralichthys olivaceus) and rabbit erythrocytes, and weakly chicken erythrocytes. In contrast, AP2 had no significant hemagglutinating activity toward any erythrocytes tested, except for weak activity on flounder erythrocytes, suggesting that the C-terminal region of AP1 may be required for the strong hemagglutinating activity. The optimum temperature for the hemagglutinating activity of AP1 was found to be lower than that for the proteolytic activity. At acidic pHs (below pH 7.5), the hemagglutinating activity of AP1 decreased, and its pH profile resembled that of the proteolytic activity. The hemagglutinating activity of AP1 was not observed in the presence of o-phenanthroline or synthetic and proteinous substrates, but different kinds of saccharides and lipids had no effect. While the proteolytic activity of AP1 was not affected by CaCl2, the hemagglutinating activity of AP1 decreased with increases in CaCl2 concentrations. These results suggested that the hemagglutinating activity of these proteases (AP1 and AP2) was most likely caused by their proteolytic action on erythrocyte cell surfaces.
