چکیده
Practical synthesis of tetrasaccharide sulfates, 6((GlcNAc))-O-Su-SiaLe(X)-OCH(2)CH(2)CH(2)NH(2) and 6((Gal))-O-Su-SiaLe(X)-OCH(2)CH(2)CH(2)NH(2) (Su( )SO(3)H), selectin ligands, and leu- kocyte trafficking agents is presented. Both sulfates were synthesized starting from the same precursor, protected SiaLe(x), by the conventional procedures of carbohydrate chemistry. The sulfated SiaLe(x) derivative was modified at the spacer group to give 6((Gal))-O-Su-SiaLe(x)- OCH(2)CH(2)CH(2)NH-COCH(2)CH(2)C[triple bond]CH, convenient for "click chemistry" mode conjugation with an azido carrier, particularly, for the synthesis of an immunogen.

Novel Sulfated Lymphocyte Homing Receptors and Their Control by a Core1 Extension β1,3-N-Acetylglucosaminyltransferase
L-selectin mediates lymphocyte homing by facilitating lymphocyte adhesion to addressins expressed in the high endothelial venules (HEV) of secondary lymphoid organs. Peripheral node addressin recognized by the MECA-79 antibody is apparently part of the L-selectin ligand, but its chemical nature has been undefined. We now identify a sulfated extended core1 mucin-type O-glycan, Gal beta 1-->4(sul...
متن کاملAltered O-glycosylation and sulfation of airway mucins associated with cystic fibrosis.
Cystic fibrosis (CF) is the most lethal genetic disorder in Caucasians and is characterized by the production of excessive amounts of viscous mucus secretions in the airways of patients, leading to airway obstruction, chronic bacterial infections, and respiratory failure. Previous studies indicate that CF-derived airway mucins are glycosylated and sulfated differently compared with mucins from ...
متن کاملBinding of the influenza A virus to cell-surface receptors: structures of five hemagglutinin-sialyloligosaccharide complexes determined by X-ray crystallography.
The structures of five complexes of the X-31 influenza A (H3N2) virus hemagglutinin with sialyloligosaccharide receptor analogs have been determined from 2.5 to 2.8 A resolution by X-ray crystallography. There is well-defined electron density for three to five saccharides in all five complexes and a striking conformational difference between two linear pentasaccharides with the same composition...
متن کاملEctopic expression of a GlcNAc 6-O-sulfotransferase, GlcNAc6ST-2, in colonic mucinous adenocarcinoma.
The content of sulfated glycans having 6-O-sulfated GlcNAc residues alters in the course of colonic carcinogenesis. We previously characterized two GlcNAc 6-O-sulfotransferases (SulTs), SulT-a and -b, expressed in colonic normal tissues and adenocarcinomas [Seko et al. (2000) Glycobiology, 10, 919-929]. Levels of the enzymatic activities of SulT-a in normal colonic mucosa are higher than those ...
متن کاملCopolymers of chondroitin 4-sulfate and chondroitin 6-sulfate in chick embryo epiphyses and other cartilage.
Tetrasaccharides were prepared from chondroitin sulfate by means of a limited degradation with chondroitinase ABC. Tetrasaccharides containing one sulfate per disaccharide unit were isolated and were found to be of three types: a tetrasaccharide with two 6-sulfated disaccharide units, a tetrasaccharide with two 4-sulfated disaccharide units, and a tetrasaccharide with one 4-sulfated disaccharid...
