  phenyl 2,3,6-tri-O-benzoyl-4-O-(2,6-di-O-benzoyl-β-D-galactopyranosyl)-β-D-glucopyranoside 在 4-二甲氨基吡啶 、 偶氮二异丁腈 、 三正丁基氢锡 作用下， 以 吡啶 、 二氯甲烷 、 苯 为溶剂， 反应 4.0h， 生成 (2S,3R,4S,6S)-6-((benzoyloxy)methyl)-2-(((2R,3R,4S,5R,6S)-4,5-bis(benzoyloxy)-2-((benzoyloxy)methyl)-6-phenoxytetrahydro-2H-pyran-3-yl)oxy)tetrahydro-2H-pyran-3,4-diyl dibenzoate

  Synthesis of deoxy and acylamino derivatives of lactose and use of these for probing the active site of Neisseria meningitidis N-acetylglucosaminyltransferase

  摘要：

  Derivatives of lactose with the galactose ring substituents replaced by deoxy or acylamino functions were prepared. The 2'-, 3'-. 4'- and 6'-deoxy, 3'-acetamido and 3'-benzamido derivatives of phenyl 4-O-(beta-D-galactopyranosyl)-beta-D-glucopyranoside (phenyl P-lactoside) were synthesized from disaccharide or monosaccharide precursors. The derivatives were tested as substrates for the N-acetylglucosaminyltransferase from Neisseria meningitidis, which uses lactosyl derivatives as acceptors and UDP-GlcNAc as the donor in a beta-(1-->3) glycosylation reaction. The 6'-deoxy derivative was nearly threefold as active as phenyl beta-lactoside, whereas the 2'- and 4'-deoxy derivatives were less active. The other derivatives were inactive, as expected.
