Theaflavin-3-gallate
Based on 1 Customer Validation
Theaflavin-3-gallate, a black tea theaflavin monomer, is regarded as the biologically important active component of black tea and provides health benefits. Theaflavin-3-gallate acts as prooxidants and induces oxidative stress in the carcinoma cells. Theaflavin-3-gallate reacts directly with reduced glutathione (GSH) in a time- and concentration-dependent manner. Theaflavin-3-gallate induces apoptosis and G1 cell cycle arrest in ovarian cancer A2780/CP70 cells through p53-dependent pathways. Theaflavin-3-gallate induces DNA damage through ATM/Chk/p53 pathway.

Beschreibung
In Vitro
Theaflavin-3-gallate (Compound TF-2A) (0-500 μM, 24 h) results in toxicity in cancer cells (CAL27 and HSC-2)[1].
Theaflavin-3-gallate (0-250 μM, 3 h) has no effect on the HF-1 fibroblasts but almost totally eliminates the intracellular GSH content in the CAL27 cells[1].
Theaflavin-3-gallate (0-40 μM, 24 h) inhibits the proliferation of ovarian cancer cell lines (A2780/CP70 cells) and induces cytotoxicity[2].
Theaflavin-3-gallate (0-20 μM) induces apoptosis and G1 cell cycle arrest in A2780/CP70 cells[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Lösungsmittel & Löslichkeit
In Vitro:
DMSO : 50 mg/mL (69.77 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (protect from light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (3.49 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
