Difopein TFA
Based on 1 Customer Validation
Difopein TFA is a 14-3-3 protein inhibitor. Difopein TFA acts as an apoptosis inducer, regulates apoptosis-related proteins, downregulates Bcl-2, upregulates Bax, activates caspase-9 and caspase-3, and induces nuclear fragmentation, membrane-enclosed apoptotic bodies and DNA ladder formation. Difopein TFA serves as a tumor growth inhibitor, which inhibits the proliferation of glioma cells and induces their apoptosis in in vivo nude mouse models. Difopein TFA is applicable to glioma-related research.

Difopein (24-48 h) TFA induces time-dependent apoptosis in human U251 and U87 glioma cells, causes time-dependent increases in both early and late apoptosis, and triggers apoptotic DNA fragmentation in U251 cells[1].
Difopein (24-48 h) TFA alters the cell cycle distribution of U251 cells, causing time-dependent cell arrest at the G1 phase, while the proportions of cells in the S and G2 phases decrease; at 24 h and 48 h post-transfection, the proportions of G1-phase cells reach 73.9% and 84.8%, respectively[1].
Difopein (24-48 h) TFA downregulates the anti-apoptotic protein Bcl-2 and upregulates the pro-apoptotic protein Bax at both mRNA and protein levels, and activates caspase-9 and caspase-3 in human U251 glioma cells[1].

용액&용해도
DMSO : ≥ 100 mg/mL
* "≥" means soluble, but saturation unknown.
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 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL; 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 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
