of the parent quercetin. In addition, it inhibited aldose reductase isolated from rat lenses with an IC50 in the low micromolar range and attenuated sorbitol accumulation in isolated rat eye lenses with an activity comparable with that of quercetin. Moreover, it scavenged stable free-radicals of DPPH more efficiently than did quercetin. By inhibiting α-glucosidase and affecting both the polyol pathway
槲皮素3' - O-(3-氯新戊酰基)槲皮素(CPQ)的新型衍生物以非竞争性方式抑制α-葡萄糖苷酶,其功效超过了亲本槲皮素。此外,它以低微摩尔范围的IC50抑制从大鼠晶状体分离的醛糖还原酶,并减弱了离体大鼠晶状体中山梨醇的蓄积,其活性与槲皮素相当。此外,它比槲皮素更有效地清除了DPPH的稳定自由基。通过抑制α-葡萄糖苷酶并影响多元醇途径和氧化应激,CPQ代表了糖尿病并发症多目标药理学的有前途的药物。
