We studied the stereoselective synthesis of several beta-N-aryl-glycosides by glycosylation of aromatic primary amines using unprotected carbohydrates in aqueous solution. This was the first report showing an efficient method for the synthesis with one step of beta-N-glycosyl-para-amino-phenyl alanine building blocks for the tumor-associated carbohydrate antigen (TACA) glycopeptides synthesis. Analysis of products by 1H and 13C NMR indicated that the Amadori rearrangement had not occurred after formation of the stereoselective beta-N-glycoside bond (natural N-glycoprotein linkage). The study of the chemical and enzymatic stability in aqueous media of beta-N-aryl-glycosides synthesized was also investigated. For the first time we have shown that the N-glycosidic bond was relatively stable at pH near to 7 and more stable than the O-glycosidic bond to enzymatic hydrolysis. This higher enzymatic and chemical stability of the N-glycosidic bond is essential to envisage further development of stable TACA building blocks.

Researchers are common within chemical engineering and are often tasked with creating and developing new chemical techniques, frequently combining other advanced and emerging scientific areas.

Moringa oleifera seed cake, which is the coproduct of oil extraction, may be a source of lectin. This study reports the purification of a lectin from M. oleifera cake (WSMoLC) and the determination of its effect on larvae, eggs and oviposition of Aedes aegypti. WSMoLC was isolated (purification fold: 3573) by treatment of water extract with ammonium sulphate (60%) and chromatography of lectin-rich fraction on chitin column. In gel trypsin, digestion followed by mass spectrometry revealed the similarity of WSMoLC peptides with other M. oleifera seed proteins. WSMoLC exerted deleterious effects on larvae (LC50: 0.89 mg/mL) and eggs (EC50: 0.14 mg/mL) and served as an oviposition-stimulant at the concentration of 0.1 mg/mL. Larvicidal activity may be linked to lectin resistance to digestion and stimulatory effect on the activities of protease and alpha-amylase at larvae gut. Furthermore, the larvae did not start to express different enzymes in response to lectin effect. This study adds value to M. oleifera seed cake as a source of insecticidal lectin with high potential to be used in control of A. aegypti because, at the same time that it stimulates the oviposition by females, it could kill the eggs or larvae that may arise from them.

A chemoenzymatic approach is described towards the branched tetrasaccharide repeating unit, beta-d-Galp-(14)-beta-d-Glcp-(16)-[beta-d-Galp-(14)]-beta-d-GlcpNAc, of Streptococcus pneumoniae type 14 in a form suitable for conjugation. The linear trisaccharide acceptor, beta-d-Galp-(14)-beta-d-Glcp-(16)-beta-d-GlcpNAc-(1O)CH2CH=CH2, was synthesized by coupling of peracetylated lactosyl trichloroacetimidate to a suitably protected glucosamine building block and subsequent deprotection steps. The obtained derivative was found to be a good acceptor for bovine milk beta-1,4-galactosyltransferase, and the resulting branched tetrasaccharide beta-allyl glycoside was isolated and characterized by NMR spectroscopy and FAB mass spectrometry. Reaction of the anomeric allyl function with cysteamine under UV-irradiation gave the beta-aminoethylthio-extended glycoside suitable for further coupling of the tetrasaccharide to protein carriers.

(d)-Glucosamine and other nutritional supplements have emerged as safe alternative therapies for osteoarthritis (OA), a chronic and degenerative articular joint disease. In our preceding paper, a series of novel O-6 phosphate N-acetyl (d)-glucosamine prodrugs aimed at improving the oral bioavailability of N-acetyl-(d)-glucosamine as its putative bioactive phosphate form were shown to have greater chondroprotective activity in vitro when compared to the parent agent. In order to extend the SAR studies, this work focuses on the O-3 and O-4 phosphate prodrugs of N-acetyl-(d)-glucosamine bearing a 4-methoxy phenyl group and different amino acid esters on the phosphate moiety. Among the compounds, the (l)-proline amino acid-containing prodrugs proved to be the most active of the series, more effective than the prior O-6 compounds, and well processed in chondrocytes in vitro. Data on human cartilage support the notion that these novel O-3 and O-4 regioisomers may represent novel promising leads for drug discovery for osteoarthritis.

We describe a general method that permits characterization of 100-pg to 1-ng quantities of sugars.Thus, oligosaccharides are subjected to methanolysis, followed by per-p-bromobenzoylation or pernaphthoylation, and the methyl glycoside peresters are separated by high-pressure liquid chromatography.The method is also applicable to amino and acetamido sugars.If required, the separated sugar derivatives may be unequivocally identified by the characteristic quasi-M+ peaks of bromobenzoates and extrema of excitation-split circular-dichroism (c.d.) curves.Furthermore, as the c.d. extrema of polybenzoates are predictable from extrema of component dibenzoate units, the c.d. data yield information on the unknown spatial disposition of -OH, -NH2, and -NHAc groups of glycopyranoses.Application of the method is demonstrated with viridopentaose C, a pentasaccharide obtained from the antibiotic sporaviridin.

Substrate inhibition hinders chitinolytic beta-N-acetyl-d-hexosaminidases in producing N-acetyl-d-glucosamine (GlcNAc), the valuable chemical widely applied in medical and food industries. Here we focused on a promising chitinolytic enzyme, OfHex1 from the insect, Ostrinia furnacalis. By structural analysis of OfHex1, five residues nearby the active pocket including V327, E328, Y471, V484 and W490 were chosen and nine mutants including V327G, E328Q, E328A, Y471V, V484R, W490A, W490H, V327G/V484R/W490A and V327G/Y471V/W490H were constructed and recombinantly expressed in Pichia pastoris. The best-performing mutant, W490A, obtained by a higher yield of 5 mg/L, did not show substrate inhibition even when 5 mM of the substrates, (GlcNAc)2-4, were applied. The kcat/Km values for (GlcNAc)2-4 are 239.8, 111.3 and 79.8 s-1 mM-1, respectively. Besides, the pH stability of the mutant ranges from pH 4 to 11 and the thermal stability is up to 50 C. This work suggests the W490A mutant might be an ideal biocatalyst for GlcNAc production from chitin.

The hydrolysis kinetics of the chitin monomer, N-acetyl-D-glucosamine, in HCl, HClO4, and H3PO4 was studied in relation to the acid concentration. The rate constants of N-acetyl-D-glucosamine deacetylation and D(+)-glucosamine formation in HClO4 and H 3PO4 were determined for the first time. The rate of the acetamide bond hydrolysis in N-acetyl-D-glucosamine depends on the concentrations of hydrogen ions and water. The nucleophilicity of the acid residues does not affect the rate of N-acetyl-D-glucosamine hydrolysis.
