Novel (1→3)-β-D-glucans (GPBCD, GPECD, GP6CD, and GP3CD) having reducing glucose side chains were prepared from a linear (1→3)-β-D-glucans (curdlan : CD) with halogeno glucose isopropylidene derivatives in dimethyl sulfoxide containing dimsyl sodium, followed by treatment with 40% trifluoroacetic acid to remove protecting isopropylidene groups. The side chain glucose moiety was linked directly or through a spacer at various positions except for its anomeric carbon.
新型 (1→3)-β-D 葡聚糖(GPBCD、GPECD、GP6CD 和 GP3CD)具有还原葡萄糖侧链,由线性 (1→3)-β-D 葡聚糖(curdlan : CD)与卤代葡萄糖异亚丙基衍生物在含有二甲基亚砜(含二甲基钠)中制备而成,然后用 40% 三氟乙酸处理以去除保护性异亚丙基。侧链葡萄糖分子直接或通过间隔物连接在不同位置,但其同分异构碳除外。
