2-O-β-D-葡萄糖基-L-抗坏血酸(AA-2βG)是从枸杞中分离得到的一种天然抗坏血酸糖苷化合物,通过化学方法合成了AA-2βG及其两种类似物,并用商品化的阿卡波糖作为阳性对照,研究了三种抗坏血酸糖苷对酿酒酵母α-葡萄糖苷酶和猪胰腺α-淀粉酶的活性影响.结果显示,三种抗坏血酸糖苷对α-葡萄糖苷酶有显著的抑制作用,对α-淀粉酶抑制作用不明显,说明这三种抗坏血酸糖苷具有作为α-糖苷酶抑制剂开发的潜质.

2-O-(β-D-Glucopyranosyl)-L-ascorbic acid, a natural β-glycoside with ascorbic acid moiety present in Lycium barbarum, and its two analogues were chemically synthesized. Their inhibitory effect on yeast α-glucosidase and α-amylase were investigated with commercially available acarbose as positive control. The biological assays demonstrated the distinct inhibitory effect of these compounds on α-glucosidase activity and weak inhibitory activity against pancreatic α-amylase. The kinetic study indicated that these compounds were competitive inhibitors. These results imply that these three β-glycosides have the potential to be developed as α-glucosidase inhibitors.
