TPh A
Based on 2 publication(s) in Google Scholar
TPh A (Triphenyl Compound A) is a potent inhibitor of the nuclear protein pirin and binds specifically to pirin with a Ki of 0.6 uM. TPh A disrupts the formation of the bcl3–pirin complex. TPh A can be used as a novel small molecule tool to regulate pirin in cells.

Biological Activity
The Pirin is a nuclear protein with the nuclear factor I/CCAAT box transcription factor (NFI/CTF). Pirin proteins are highly conserved between mammals, plants, fungi, and prokaryotic organisms and are considered to belong to the cupin superfamily.TPh A (20 μM; 5 hours) reduces the amount of pirin-bound Bcl3 and inhibits the interaction between pirin and Bcl3 in HEK293T cells in a glutathione S-transferase (GST) pulldown assay (HEK293T cells are transfected with vectors that encoded bcl3-Myc and pirin-His6 for 43 h of transfection)[1].TPh A (0-100 μM; 48 hours) does not exert any potent cytotoxic activity against many human cancer cell lines, it against MCF7, MDA-MB231, HeLa, DU145, HepG2, A549, HT1080, WM266-4, and SK-MEL-28 cells with IC50 values >50 μM, and exhibits IC50 values of 27 μM, 20 μM and 26 μM for PC3 HL60 and HT29 cells, respectively[1].TPhA (0-50 μM; 48 hours) inhibits cell migration in WM266-4 cells, SK-MEL-28 cell in a concentration-dependent manner[1].

Solvent & Solubility
DMSO : 250 mg/mL (625.74 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. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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: ≥ 2.08 mg/mL (5.21 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (5.21 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.

Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
