  Regiospecific synthesis of quercetin O-β-d-glucosylated and O-β-d-glucuronidated isomers

  摘要：

  Quercetin, the polyphenolic compound, which has the highest daily intake, is well known for its protective effects against aging diseases and has received a lot of attention for this reason. Both quercetin 3-O-beta-D-glucuronide and quercetin 3'-O-beta-D-glucuronide are human metabolites, which, together with their regioisomers, are required for biological as well as physical chemistry studies. We present here a novel synthetic route based on the sequential and selective protections of the hydroxyl functions of quercetin allowing selective glycosylation, followed by TEMPO-mediated oxidation to the glucuronide. This methodology enabled us to synthesize the five O-beta-D-glucosides and four O-beta-D-glucuronides of quercetin, including the major human metabolite, quercetin 3-O-beta-D-glucuronide.

  公开（公告）日：2017-12-19

  本发明公开了一种槲皮素的衍生物及其制备方法和应用，该制备方法首先用二氯二苯基甲烷保护槲皮素邻二酚羟基，并结合苄基保护基，得到选择性保护的槲皮素衍生物，再分别单独与硫酸二甲酯、硫酸二乙酯、烯丙基溴、对甲苯磺酰氯和乙酸酐进行反应，生成相应的槲皮素衍生物。所制备的衍生化合物都表现出优于槲皮素的抑制NRK‑49F增殖活性。其中，甲基和对甲苯磺酰基复合取代的槲皮素衍生物20a‑1、14a‑2和23d‑1表现出更加优良的抑制NRK‑49F增殖活性，抑制率分别达到86.33%、78.04%、75.91%。可见，目前得到的槲皮素衍生化产物对肾成纤维细胞NRK‑49F增殖有明显的抑制作用。
