The synthesis of a novel thio-linked disaccharide of chondroitin as a potential inhibitor of polysaccharide lyases
摘要:
A thio-linked disaccharide based on the structure of the glycosaminoglycan chondroitin was synthesized as a potential inhibitor of chondroitin AC lyase from Flavobacterium heparinum for structural analysis of the active site. Instead it was found to be a slow substrate, thereby demonstrating that lyases, in contrast to glycosidases, can cleave thioglycoside links between sugars. (C) 2004 Elsevier Ltd. All rights reserved.

日期:——
phase synthesis of carbohydrate-functionalized oligo(amidoamines) with different functionalization patterns utilizing a novel alphabet of six differently glycosylated buildingblocks. Highly efficient in flow conjugation of thioglycosides to a double-bond presenting diethylentriamine precursor is the key step to prepare these buildingblocks suitable for fully automated solid-phase synthesis.

Lipid vesicles comprise a lipid bilayer which includes an analog of a cell-surface receptor such as dicetyl phosphate, stearylamine, 6-(5-cholesten-3β-yloxy)hexyl 1-thio-β-L-fucopyranoside, 6-(5-cholesten-3β-yloxy)hexyl 1-thio-β-D-galactopyranoside, 6-(5-cholesten- 3β-yloxy)hexyl 1-thio-a- D-mannopyranoside, 6-(5-cholesten- 3-yloxy)hexyl 2-acetamido-3-deoxy- 1-thio-β-D-galactopyranoside, 6-(5-cholesten- 3β-yloxy)hexyl 6-amino-6-deoxy-1-thio- β-D-galactopyranoside or 6-(5-cholesten- 3p-yloxy)hexyl 6-amino-6-deoxy-1- thio-a-D-mannopyranoside, together with cholesterol, distearoyl phospatidylcholine and an effective amount of a physiologically compatible radioactive tracer or a cytotoxic or therapeutic agent as a part of the vesicles. The vesicles of this invention can be administered to mammalian, including human, hosts and have been found to release the contents of the vesicles in a predetermined manner, and in some cases to be rapidly concentrated in the lymphatic system and/or liver, lungs, or spleen of the host.
