Anthraquinone–lectin hybrids were effectively synthesized using water‐soluble anthraquinone derivative 11 with concanavalin A (ConA) and hygrophorus russula lectin (HRL) to give anthraquinone–ConA (16) and anthraquinone–HRL (17) hybrids, respectively. These anthraquinone–lectin hybrids effectively and selectively degraded oligosaccharides containing a mannose residue as a non‐reducing terminal sugar
使用水溶性蒽醌衍生物11与伴刀豆球蛋白A(ConA)和百草纲红花凝集素(HRL)有效合成蒽醌-凝集素杂种,从而分别得到蒽醌-ConA(16)和蒽醌-HRL(17)杂种。这些蒽醌-凝集素杂交体在无添加剂的长波紫外光照射下,在无添加剂的条件下,能有效,选择性地降解含有甘露糖残基的寡糖,作为非还原性末端糖,对ConA和HRL具有亲和力。此外,蒽醌-HRL(17)通过识别寡糖中糖的类型和糖苷键连接特征,选择性地仅光降解几种甘露糖苷中对HRL具有高亲和力的Man(α1,6)Man。
