The preparation of deoxy derivatives of mannose-1-phosphate and their substrate specificity towards recombinant GDP-mannose pyrophosphorylase from Salmonella enterica, group B
摘要:
2-Deoxy-alpha-D-glucose-1-phosphate, 3-deoxy-alpha-D-arabino-hexose-1-phosphate, 4-deoxy-alpha-D-lyxo-hexose-1-phosphate, and alpha-D-lyxose-1-phosphate were synthesised chemically, and evaluated as substrates for a recombinant GDP-mannose pyrophosphorylase (Salmonella enterica, group B, cloned in Escherichia coli). The deoxy derivatives were all substrates for the enzyme, with slightly reduced V-max values but significantly higher K-m values than those recorded for the native substrate, mannose-1-phosphate. The pyrophosphorylase was used for the synthesis of GDP-mannose analogues GDP-2-deoxy-glucose and GDP-lyxose on a milligram scale. (C) 2000 Elsevier Science Ltd. All rights reserved.

La présente invention concerne en tant que produits industriels nouveaux: (i) les composés [4-(4-cyanobenzoyl)phényl] glycopyranosides de formule I dans laquelle le groupe glycopyranosyle R représente un groupe β-D-arabinopyranosyle, β-D-lyxopyranosyle, β-D-ribopyranosyle, β-D-galactopyranosyle, $b(g)-D-mannopyranosyle, β-L-arabinopyranosyle, β-L-xylopyranosyle, α-L-arabinopyranosyle, α-L-xylopyranosyle ou β-L-rhamnopyranosyle; et, (ii) leurs esters résultant de l'estérification d'au moins d'une fonction OH de chaque groupe glycopyranosyle par un acide alcanoïque ou cycloalcanoïque en C2-C4. Ces nouveaux [4-(4-cyanobenzoyl)phényl] glycopyranosides sont utiles en thérapeutique vis-à-vis de la plaque d'athérome.
