چکیده

The chemical synthesis of a series of mucin-type oligosaccharide fragments 1-7 containing an α-linked aminopropyl spacer ready for glycoarray attachment is reported. A highly convergent and stereoselective strategy that employs two different orthogonal protected galactosamine building blocks was used to access all of the targets. A tandem deprotection sequence, that did not require chromatography-based purification between steps, was employed to globally unmask all protecting groups and all final targets were isolated in good to excellent yields.

The pattern of glycosyl- and sulfotransferase activities in cancer cell lines: a predictor of individual cancer-associated distinct carbohydrate structures for the structural identification of signature glycans.

Carbohydrate chains of cancer glycoprotein antigens contain major outer changes dictated by tissue-specific regulation of glycosyltransferase genes, the availability of sugar nucleotides, and competition between enzymes for acceptor intermediates during glycan elongation. However, it is evident from recent studies with recombinant mucin probes that the final glycosylation profiles of mucin glyc...

Mucin-Type O-Glycosylation in Gastric Carcinogenesis

Mucin-type O-glycosylation plays a crucial role in several physiological and pathological processes of the gastric tissue. Modifications in enzymes responsible for key glycosylation steps and the consequent abnormal biosynthesis and expression of their glycan products constitute well-established molecular hallmarks of disease state. This review addresses the major role played by mucins and asso...

Glycan array screening reveals a candidate ligand for Siglec-8.

Sialic acid-binding immunoglobulin-like lectin 8 (Siglec-8) is selectively expressed on human eosinophils, basophils, and mast cells, where it regulates their function and survival. Previous studies demonstrated sialic acid-dependent binding of Siglec-8 but failed to reveal significant substructure specificity or high affinity of that binding. To test a broader range of potential ligands, a Sig...
