The Reactions Of Sni2,Ecl2.Dioxane,And (Co)(5)W=ecl2.Thf (E = Ge Or Sn) With Et3E'H (E' = Si Or Ge) occur As Redox Processes. Depending On The Nature Of The Reagents,The Reactions Afford Products Of Oxidative Coupling (Et3Sisiet3) And/or Haloiodination (Et3Six And Et3Gex) Of Triethylsilane (Triethylgermane). The Proposed Mechanism Of These Reactions Involves The Electron Transfer To Form Radical-Ion Pairs.

摘要:The invention relates to a process for the organic synthesis of oligosaccharides constituting or comprising fragments of acid mucopolysaccharides comprising the reaction of two compounds constituted or terminated by units of glucosamine structure and of uronic acid structure respectively, said units being specifically substituted. This process particularly enables valuable anticoagulant drugs to be obtained.

权利人:ALBERTA RES COUNCIL
摘要:Disclosed are methods for the enzymatic synthesis of alpha-sialylated oligosaccharide glycosides. Specifically, in the disclosed methods, sialyltransferase is activated to transfer an analogue of sialic acid, employed as its CMP-nucleotide derivative, to an oligosaccharide glycoside. The analogue of sialic acid and the oligosaccharide employed in this method are selected to be compatible with the sialyltransferase employed.

标 题:Expedient synthesis of core disaccharide building blocks from natural polysaccharides for heparan sulfate oligosaccharide assembly
发明人：HSIEH-WILSON LINDA C; PAWAR NITIN J; WANG LEI
权利人:CALIFORNIA INST OF TECHN
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:An improved method for the chemical synthesis of glycosylated peptides has been developed. The method uses stereoselective glycan synthesis and chemical peptide ligation to produce glycopeptides at lower-cost and with higher efficiency/yield compared to conventional methods. In particular, a method for the large-scale, chemical synthesis of hydroxylated amino acid building blocks and glycosylated amino acids suitable for solid phase peptide synthesis (SPPS) are disclosed. SPPS-based methods using the glycosylated amino acids to chemically synthesize adiponectin-like peptides are also described. In vivo studies show that the adiponectin mimicking glycopeptides exhibit significant anticancer, anti-obesity and insulin sensitizing effects. Pharmaceutical compositions of the synthetic glycopeptides and methods of use thereof in treating diseases associated with deficient adiponectin are also described.
