摘要:The invention provides important intermediate compounds for the synthesis of acidic glycolipids which are identical with the glycolipid antigens isolated from the acidic glycolipid fractions of peripheral nerve and embryonic central nervous system and preparation methods thereof. By the adoption of the present intermediate compounds, sulfation of 3-hydroxyl group of end glucuronic acid portion of the acidic glycolipid can be quite easily carried out and total synthetic yield be greatly improved.

摘要:A process for the synthesis of beta linked low molecular weight polymers of galactosamine and glucosamine has been developed. Through the use of high amounts of activating agents, efficient coupling of stable monomers is achieved. Using this process, chain extension is through the addition of single monomers, providing populations of single chain length polyhexosamines.

摘要:Methods for the preparation of oligosaccharide products from polysaccharide starting materials are disclosed. The methods include: hydrolyzing a glucosamine-containing polysaccharide starting material, such as heparin or heparosan, under conditions sufficient to form an oligosaccharide intermediate (e.g., a GlcN-IdoA disaccharide intermediate or a GlcA-GlcN disaccharide intermediate), and converting the oligosaccharide intermediate to the oligosaccharide product. Conversion of the oligosaccharide intermediates to the oligosaccharide products may include one or more esterification, acylation, epimerization, protection, and deprotection steps. Preparation of higher-order oligomers is described, as well as methods for selective oligosaccharide sulfation.

摘要:Disclosed are methods for the preparation of monofucosylated and sialylated derivatives of the compound $g(b)Gal(1-4)$g(b)GlcNAc(1-3)$g(b)Gal(1-4)$g(b)GlcNAc-R. In particular, the methods of this invention provide for a multi-step synthesis wherein selective monofucosylation is accomplished on the 3-hydroxy group on only one of the GlcNAc units found in the $g(b)Gal(1-4)$g(b)GlcNAc(1-3)$g(b)Gal(1-4)$g(b)GlcNAc-R compound. In this step, monofucosylation is achieved by use of the $g(a)(1-3)fucosyltransferase.
