In 3T3-L1 cells, fisetin quarterhydrate suppresses PPARγ expression and lipid buildup. Fisetin quarterhydrate stimulates Sirt1 expression and suppresses preadipocyte development in its early phases. Fisetin quarterhydrate increases the binding of Sirt1 to the PPARγ promoter, which inhibits PPARγ transcriptional activity and adipogenesis by promoting Sirt1-mediated deacetylation of PPARγ and FoxO1 [1]. Fisetin quarterhydrate has considerably better binding characteristics than paclitaxel and stabilizes microtubules via binding tubulin. Microtubule-associated proteins (MAP)-2 and -4 were significantly upregulated in human prostate cancer cells treated with fisetin quarterhydrate. The proliferation, migration, and invasion of PCa cells were markedly reduced by fisetin quarterhydrate. Treatment with fisetin quarterhydrate inhibits Nudc, a protein linked to the microtubule motor dynamin/dynein complex, which controls microtubule dynamics [2].

| ln Vivo |
Treatment with fisetin quarterhydrate decreased inflammatory cell infiltration and proliferation in mice exposed to UVB radiation. In addition, treatment with fisetin quarterhydrate lowers the levels of inflammatory mediators such COX-2, PGE2 and its receptors (EP1–EP4), and MPO activity. Fisetin quarterhydrate also lowers UVB-exposed skin's levels of the inflammatory cytokines TNFα, IL-1β, and IL-6. Treatment with fisetin quarterhydrate also decreases DNA damage and indicators of cell growth, as shown by increased expression of the proteins p53 and p21 [3].

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

Oral Formulation 3: Dissolved in PEG400 (Please use freshly prepared in vivo formulations for optimal results.) |

*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.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
