Theaflavin 3,3'-digallate (TF-3) is a potent Zika virus (ZIKV) protease inhibitor with an IC₅₀ of 2.3 μM. Theaflavin 3,3'-digallat directly binds to ZIKVpro (K_d=8.86 μM) and inhibits ZIKV replication. Theaflavin 3,3'-digallat inhibits the activity of gp41 and NS2B-3 protease and has antiviral activity against HSV and HIV-1. Theaflavin 3,3'-digallate, the typical pigment in black tea, is a potent antitumor agent.

In Vitro

Theaflavin 3,3'-digallate (TF-3; 6.25, 12.5, 25 μM; 24 hours) markedly reduces viral RNA copy numbers and NS3, U87 MG protein expression in a dose-dependent manner^[1].
Theaflavin 3,3'-digallate inhibits dose-dependently ZIKV replication in Vero E6 cells (EC₅₀=7.65 μM). Theaflavin 3,3'-digallate has minor cytotoxicity up to 40 μM in Vero E6 cells. Theaflavin 3,3'-digallate can inhibit the post-entry events of the ZIKV replication cycle from gene transcription and translation levels^[1].
Theaflavin 3,3'-digallate is generally regarded as the effective component for the inhibitory effects against carcinogenesis without adverse side effects by affecting multiple signal transduction pathways, such as upregulating p53 and p21, inhibiting phosphorylation of the cell survival protein Akt and MAPK pathway, downregulation of NF-κB, shifting the ratio between pro-/antiapoptotic proteins. Theaflavin 3,3'-digallate causes a rapid and sustained decrease in phospho-ERK1/2 and -MEK1/2 protein expression. Theaflavin 3,3'-digallate inhibits HCT116 cell growth with an IC₅₀ of 17.26 μM^[2].

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.

Protocol 1

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 5 mg/mL (5.76 mM); Clear solution

This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
