    Description

    Myricetin is a common plant-derived flavonoid with a wide range of activities including strong anti-oxidant, anticancer, antidiabetic and anti-inflammatory activities.

    In Vitro

    Myricetin exhibits the scavenging activity towards a number of radicals and ions. It displays poor activity (IC50 value=1.4 mg/mL) in a superoxide dismutase (SOD)-like activity assay[1]. It prevents cancer cell death via apoptosis via regulation of PI3K/Akt and MAPK signalling pathways[2].
    Myricetin exhibits antiphotoaging effects by quenching causative free radicals in the skin. Myricetin is able to suppress UVB-induced COX-2 expression in mouse skin epidermal JB6 P+ cells. It inhibits UVB-induced initiation of activator protein-1 and NF-κβ, as well as Fyn kinase activity[1].
    Myricetin inhibits viability of SKOV3 ovarian cancer cells in a dose-dependent manner. It induces DNA DSBs and ER stress, which leads to apoptosis in SKOV3 cells[3].
    Myricetin inhibits human Hsp70 by more than 80% with IC50 values of 83, 11 and 12 μM, respectively[4].

    In Vivo

    Treatment of orthotopic pancreatic tumors with myricetin results in tumor regression and decreases metastatic spread[2]. Exposure to 150 μM myricetin causes 14%, 26%, 5% and 49% inhibition of rabbit platelet aggregation, induced by ADP, arachidonic acid, collagen and PAF, respectively[5].

    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: ≥ 2.08 mg/mL (6.54 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

      Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
    • Protocol 2

      Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

      Solubility: ≥ 2.08 mg/mL (6.54 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

      Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

    Cell Assay
    [2]

    Pancreatic cancer cells (MIA PaCa-2, Panc-1 or S2-013) or normal pancreatic ductal cells (PDCs) are treated with myricetin (12.5–200 μM). Cell viability is determined using the Dojindo Cell Counting Kit-8. Cells are seeded onto a 96-well plate at 1×104 cells per well and allowed to adhere overnight. After treatment with myricetin at various concentrations for 24 hours, 10 μL of the tetrazolium substrate is added to each well of the plate. Plates are incubated at 37°C for 1 hour, after which the absorbance at 450 nm is measured[2].

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

    Animal Administration
    [2]

    Mice: Mice are given daily intraperitoneal injections of myricetin (30mg/kg in the MIA PaCa-2 model and 50mg/kg in the S2-013 model) or vehicle (DMSO) for 35 days (MIA PaCa-2 model) or 18 days (S2-013 model). Ultrasound measurements are performed at regular intervals to monitor tumor growth. At the end of the in vivo experiment, tumor size is measured using calipers and tumor volume is calculated[2].

    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.
