Total synthesis of the collagen glycosylated cross-link β-d-galactopyranosyl-O-pyridinoline and of its unnatural epimer β-d-galactopyranosyl-O-epipyridinoline
摘要:
A short parallel synthesis Of beta-D-galactopyranosyl-O-pyridinoline (Ga1-PYD), a collagen glycoconjugated cross-link, and of Ga1-epiPYD, a (5S)-epimer, useful as internal standard in the analytical evaluation of the natural isomer in human tissue, is reported.

日期:2009.4
Two regioisomeric sialylated tetrasaccharides found in goat milk have been obtained in excellent yield by a concise synthesis using a common disaccharide intermediate. Regioselective glycosylations and a minimal number of protecting-group manipulations are the key features of this synthetic strategy.

This disclosure provides glycan-conjugated compounds that specifically bind to anti -GM1 autoantibodies. These glycan-conjugated compounds can include a polymer backbone or support configured to display multiple glycan groups that are designed to mimic the natural GM1 epitope. The glycan-conjugated compounds can also be configured on a solid support. The linked glycan groups can be a novel analogue of the GM1 epitope. When several such glycan groups are configured on a polymeric backbone, the resulting compound provides for potent and specific binding to anti-GM1 IgG and IgM isotype autoantibodies in patient sera. This disclosure thus provides glycan-containing compounds of formula (I) that mimic the natural GM1 epitope, and therapeutically useful polymers that include a multitude of such ligands, designed to bind anti-GM1 antibodiesin vitrofor diagnostic use, and to sequester and eliminate anti-GM1 antibodiesin vivoor extracorporeal (ex vivo) for the treatment anti-GM1 autoantibody related neuropathies.
