  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.

  Protected quercetin was first transformed selectively in its 3-O-beta-D-glucoside. Further protection of the remaining phenolic hydroxyl group allows a clean oxidation of the glucoside by TEMPO/NaOCl/NaBr under phase transfer conditions into the corresponding glucuronide which was cleanly deprotected to quercetin-3-O-beta-D-glucuronide.

  A series of novel quercetin diacylglucosides were designed and first synthesized by Steglich esterification on the basis of MRSA strains inhibiting natural compound A. The in vitro inhibition of different multidrug resistant bacterial strains and Escherichia coli DNA gyrase B was investigated. In the series, compound 10h was up to 128-fold more potent against vancomycin-resistant enterococci and more effective than A, which represents a promising new candidate as a potent anti-MRSA and anti-VRE agent.
