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

Cell experiment: |
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]. |
|
Animal experiment: |
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]. |
