5‐trihydroxybenzene. All synthesized benzophenone O‐glycosides were evaluated for their inhibitory activities against α‐glucosidase. Of these, benzophenone O‐glycosides 4 and 10 exhibited the most potent inhibitory activity in vitro against α‐glucosidase with IC50 values of 168.7 ± 13.9 and 210.1 ± 23.9 µM, respectively, when compared with that of the positive control acarbose with an IC50 value of 569.3 ± 49.7 µM
从沉香的叶子中分离出的二苯甲酮 O-糖苷(iriflophenone 2-O-α-L-rhamnopyranoside:1 和 aquilarisinin:2)的首次全合成是通过适当的保护基操作完成的从市售的 L-鼠李糖、D-葡萄糖、D-半乳糖、D-甘露糖、D-木糖和 1,3,5-三羟基苯开始糖基化。评估了所有合成的二苯甲酮 O-糖苷对 α-葡萄糖苷酶的抑制活性。其中,与阳性对照阿卡波糖的 IC50 值相比,二苯甲酮 O-糖苷 4 和 10 对 α-葡萄糖苷酶的体外抑制活性最强,IC50 值分别为 168.7 ± 13.9 和 210.1 ± 23.9 µM 569.3 ± 49.7 µM。
