Fisetin (Fustel; CCRIS9034; NSC40701; 3, 7, 3′, 4′-tetrahydroxyflavone) is a naturally occuring and dietary flavonoid isolated from/found in a variety of fruits and vegetables (i.e. strawberries, apples, persimmons, onions and cucumbers). It has many important biological activity including anti-inflammatory, anti-oxidant, anti-diabetic, anti-invasive, anti-tumorigenic, neuroprotective, anti-angiogenic, and cardioprotective effects in cell culture and in animal models relevant to human diseases. It is a potent sirtuin activating compound (STAC) and an agent that modulates sirtuins. It also acts as a tubulin inhibitor/stabilizer. Fisetin is a structurally distinct chemical belonging to the flavonoid class of polyphenols.
ln Vitro |
Fisetin reduces lipid accumulation and lowers PPARγ expression in 3T3-L1 cells. Fisetin suppresses early phases of preadipocyte development and stimulates Sirt1 expression. Fisetin stimulates Sirt1-mediated deacetylation of PPARγ and FoxO1, boosts the binding of Sirt1 to the PPARγ promoter, consequently decreasing PPARγ transcriptional activity, thereby inhibiting adipogenesis [1]. Fisetin binds tubulin and stabilizes microtubules, having binding properties substantially superior to those of paclitaxel. Fisetin treatment of human prostate cancer cells resulted in substantial overexpression of microtubule-associated proteins (MAP)-2 and -4. Fisetin strongly suppresses PCa cell growth, migration and invasion. Nudc, a protein linked with the microtubule motor dynein/dynamin complex that governs microtubule dynamics, is inhibited by Fisetin therapy [2].

ln Vivo |
Treatment with fisetin decreased inflammatory cell infiltration and proliferation in mice exposed to UVB rays. Additionally, treating with fisetin lowers the levels of inflammatory mediators like COX-2, PGE2 and its receptors (EP1–EP4), and MPO activity. Moreover, fisetin lowers UVB-exposed skin's concentrations of the inflammatory cytokines TNFα, IL-1β, and IL-6. Increased expression of the proteins p53 and p21 indicates that fisetin treatment also reduces DNA damage and markers of cell proliferation [3].

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (7.27 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (7.27 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: 10 mg/mL (34.94 mM) in 45% PEG300 5% Tween-80 50% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
