Theaflavin 3,3'-digallate (TF-3; 6.25, 12.5, 25 μM; 24 hours) dose-dependently and dramatically lowers the amount of viral RNA copies and the expression of the NS3 and U87 MG proteins [1]. ZIKV replication in Vero E6 cells is inhibited by theaflavin 3,3'-digallate in a dose-dependent manner (EC50=7.65 μM). Up to 40 μM, theaflavin 3,3'-digallate exhibits a modest cytotoxic effect on Vero E6 cells. At the transcription and translation levels of genes, theaflavin 3,3'-digallate can impede post-entry processes in the ZIKV replication cycle [1]. It is generally accepted that theaflavin 3,3'-digallate inhibits carcinogenesis without causing unfavorable side effects by interfering with multiple signal transduction pathways, including p53 and p21 up-regulation, Akt phosphorylation inhibition, and MAPK pathways. components that are active. A downregulation of NF-κB modifies the ratio of pro-to anti-apoptotic proteins. Theaflavin 3,3'-digallate causes the expression of phospho-ERK1/2 and -MEK1/2 proteins to rapidly and persistently decline. HCT116 cell growth is inhibited by theaflavin 3,3'-digallate, with an IC50 of 17.26 μM[2].

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (2.88 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 25.0 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: ≥ 2.5 mg/mL (2.88 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 25.0 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: 50 mg/mL (57.56 mM) in PBS (add these co-solvents sequentially from left to right, and one by one), clear 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.
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.
