    摘要:
    Transgalactosylated products of branched cyclodextrins (glucosyl-alphaCD, -betaCD, -gammaCD, and maltosyl-alphaCD, -betaCD, -gammaCD)were synthesized by beta-D-galactosidases from Bacillus circulans and Penicillium multicolor using lactose as a donor substrate and branched CDs as acceptors. Eighteen beta-D-galactosylated branched CDs were isolated and purified by HPLC. Their structures were elucidated by FABMS and C-13 NMR spectroscopies, and methylation analysis. The chromatographic behavior of these novel heterogeneous branched CDs on three HPLC columns of different separation modes was compared.

    Jack bean α-mannosidase had a wide acceptor specificity and could transfer mannosyl residues to various acceptors such as d-fructose, l-arabinose, maltose, lactose, and sucrose. The structures of the transferred products of branchd cyclodextrins (CDs) (glucosyl-βCD, maltosyl-αCD, and maltosyl-βCD) were found to be α-d-mannosyl-(1→6)-α-d-glucosyl-(1→6)-βCD, α-d-mannosyl-(1→6)-α-d-glucosyl-(1→4)-α-d-glucosyl-(1→6)-αCD and α-d-mannosyl-(1→6)-α-d-glucosyl-(1→4)-α-d-glucosyl-(1→6)-βCD, respectively. Almond α-mannosidase also produced the same transmannosylated products of branched CDs.

    Branched cyclomalto-oligosaccharides (cyclodextrins) were synthesised from cyclomalto-oligosaccharides and maltose or maltotriose through the reverse action of Pseudomonas isoamylase. The reaction rate was greater with maltotriose than with maltose, and with increasing size of the cyclomalto-oligosaccharide (cG6 less than cG7 less than cG8). Maltotriose is effective as both a side-chain donor and acceptor

    (cyclodextrin carboxylic acid) derivatives were synthesized by microbial oxidation using Pseudogluconobacter saccharoketogenes to oxidize five types of branched cyclodextrins, including maltosyl beta-cyclodextrin (maltosyl-beta-CyD). For each novel cyclodextrin carboxylic acid derivative synthesized, the hydroxymethyl group of the terminal glucose residue in the branched part of the molecule was regiospecifically

    use of activated carbon as a new catalyst for the synthesis of branched cyclodextrins (CDs). Two main methods have been used to synthesize branched CDs: a method using an enzymatic condensation or transfer reaction, and a method using a chemical reaction. However, these methods have problems such as a limited number of the types of branched CDs that can be synthesized that depend on the characteristics
    据报道,活性炭可作为葡萄糖分子间缩合反应的催化剂。本研究描述了使用活性炭作为合成支链环糊精 (CD) 的新催化剂。已使用两种主要方法来合成支链 CD:一种使用酶促缩合或转移反应的方法,以及一种使用化学反应的方法。然而,这些方法存在的问题是,取决于酶的特性,可以合成的支链 CD 的类型数量有限,所需的反应时间长(几天或更长时间),难以合成高支链 CD。取代度 (DS),需要大量对环境有害的溶剂,以及复杂且昂贵的反应。使用活性炭作为催化剂,无论分支部分中的糖类是什么类型,都可以在相对较短的时间内(几个小时)合成具有高 DS 的分支 CD。此外,由于反应是在无溶剂条件下使用活性炭进行的,因此可以减少用于生产支链 CD 的溶剂量。使用活性炭催化剂制备的支链β-CDs表现出高溶解性、高增溶能力和低溶血活性,类似于用于药物的2-羟丙基-β-CD。这些结果表明活性炭是用于支链 CD 合成的工业和环境有用
