    克雷伯氏菌10型荚膜多糖的结构。
    摘要:
    发现来自10型克雷伯氏菌的荚膜多糖以3∶1∶1∶1∶1的比例含有D-半乳糖,D-葡萄糖,D-甘露糖和D-葡萄糖醛酸。多糖的酸水解得到一种醛糖二糖醛酸,一种醛糖三糖醛酸,一种醛糖四糖醛酸和两种中性二糖,其结构已确定。天然和羧基还原的多糖已经适当地进行了甲基化分析和史密斯降解。用碱基对甲基化多糖的降解建立了葡糖糖醛酸残基之前的糖单元的身份。糖残基的端基异构构型通过用三氧化铬氧化乙酰化的天然和羧基还原的多糖来确定。根据这些研究,

    The Synthesis of Allolactose from Amygdalin
    摘要:
    An original synthetic approach to the disaccharide allolactose (1) starting from the natural glycoside amygdalin (2) has been developed. The disaccharidic gentiobiose unit present in 2 has been transformed into the allolactose moiety using a four step protocol based on the selective inversion of the C-4' OH. The efficient removal of the natural benzylic aglycone (a mandelonitrile moiety) was accomplished by catalytic transfer hydrogenolysis. The behavior of allolactose with different enzymes is also described.

    The novel fluorous support Hfb (hexakisfluorous chain-type butanoyl) was easily prepared. The Hfb group was readily introduced into the anomeric hydroxyl group of a carbohydrate, and was recyclable after cleavage. The use of the Hfb group was applicable for the rapid oligosaccharide synthesis in which the synthetic intermediates could be purified using fluorous and normal organic solvents. Each synthetic

    A novel C-glycoside of isopropylthiogalactoside (IPTG), isobutyl-C-galactoside (IBCG), is described. IBCG may be used as an IPTG substitute for increased induction of protein expression of plasmid-based genes for the production of recombinant proteins under the control of the lac promoter. IBCG offers the advantage over IPTG of being stable at ambient temperature.
