Quercimeritrin  (Synonyms: Quercetin-7-O-β-D-glucopyranoside)

Cat. No.: HY-N0419 Purity: 99.48%
Handling Instructions Technical Support

Quercimeritrin (Quercetin-7-O-β-D-glucopyranoside) is an orally active α-glucosidase inhibitor (with an IC50 of 79.88 μM against the Saccharomyces cerevisiae enzyme) and a P-gp substrate, with anti-angiogenic and antioxidant activities. Quercimeritrin does not cross the blood-brain barrier and does not inhibit cytochrome P450 enzymes. Quercimeritrin precisely binds to and inhibits the active sites of c-Kit, MMP-2, Aurora-A kinases and α-glucosidase, thereby disrupting target functions. Quercimeritrin effectively regulates postprandial blood glucose and also exhibits significant anti-angiogenic activity, which inhibits endothelial cell proliferation and microvascular growth. Quercimeritrin can be used in the research of diabetes and breast cancer.

In Vitro

Quercimeritrin has a high absorption rate in the human intestine, cannot cross the blood-brain barrier, and does not inhibit major CYPs. It is a substrate of P-gp, and fails to meet one of the Ghose rules due to its low lipophilicity[1].
Quercimeritrin (3.91-500 μM; 10-20 min) potently inhibits α-glucosidase isolated from Saccharomyces cerevisiae, with an IC50 of 79.88 μM, and exhibits a concentration-dependent inhibitory effect[2].
Quercimeritrin (3.91-500 μM; 10-20 min) weakly inhibits porcine pancreas-derived α-amylase, with an IC50 value greater than 250 μM[2].
Quercimeritrin (15.6-500 μM) competitively inhibits α-glucosidase from Saccharomyces cerevisiae and α-amylase from porcine pancreas, and exhibits higher binding affinity for α-glucosidase[2].
Quercimeritrin (10-100 μM; 72 h) inhibits the proliferation of human umbilical vein endothelial cells (HUVEC) in a dose-dependent manner, with a significant inhibitory effect observed at 100 μM[3].
Quercimeritrin (100 μM; 12 h) cannot effectively inhibit tube formation in human umbilical vein endothelial cells (HUVECs), with an inhibition rate of less than 20%[3].
Quercimeritrin (100 μM; 6 h) does not inhibit VEGF-induced HUVEC migration in Boyden chamber assays[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Proliferation Assay[3]

Cell Line: Human umbilical vein endothelial cell (HUVEC)
Concentration: 10, 100 μM
Incubation Time: 72 h
Result: Suppressed HUVEC proliferation in a dose-dependent manner at 10-100 μM.
Significantly suppressed HUVEC proliferation at 100 μM.

Cell Migration Assay[3]

Cell Line: Human umbilical vein endothelial cell (HUVEC)
Concentration: 100 μM
Incubation Time: 6 h
Result: Did not suppress VEGF-induced HUVEC migration, with migrated cell numbers similar to the positive control (VEGF alone).
In Vivo

Quercimeritrin (100-200 mg/kg; oral; single dose) significantly inhibits postprandial hyperglycemia in db/db mice, with the 200 mg/kg oral dose reducing glucose AUC0-t by 24.5% and the 100 mg/kg dose reducing glucose AUC0-t by 19.0%[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: db/db mice[2]
Dosage: 100 mg/kg; 200 mg/kg
Administration: oral; single dose
Result: Reduced postprandial glucose area under the curve (AUC) by 19.0% to 43.7 mmol/(L*h) compared to the model group (100 mg/kg dose).
Reduced postprandial glucose AUC by 24.5% to 40.7 mmol/(L*h) compared to the model group (200 mg/kg dose).
Resulted in a significantly lower postprandial blood glucose level at 120 minutes than the control and acarbose groups (200 mg/kg dose).

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (5.38 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
