As sugars form complexes with boronic acids, some sugars are used as additives for boron-containing pharmaceuticals. The binding constants of the rare sugar D-allulose with boronic acids were measured, and these showed the highest hitherto reported binding-affinity values for sugars. An NMR study clarified that D-allulose in aqueous solution forms complexes exclusively via the reaction of the 2,3-hydroxy
由于糖与硼酸形成复合物,因此某些糖被用作含硼药物的添加剂。稀有糖的结合常数d测量了具有硼酸的β-阿洛糖和糖,迄今为止显示了最高的糖结合亲和力值。NMR研究澄清了d水溶液中的β-阿洛糖糖仅通过α-阿卢木呋喃糖的2,3-羟基反应形成络合物。相反,在有机溶剂中d-阿洛糖形成源自β-铝吡喃糖的3,5-羟基的单一复合物。
