CBP/p300 |
Exposure to 1 μM TPOP146 results in a significant decrease of recovery half-life that is comparable to the construct that contained the bromodomain inactivating mutation N1168F, demonstrating that TPOP146 targets the CBP bromodomain in the nucleus and is capable of competing with acetyl-lysine mediated interactions of the CBP bromodomain in cellular environments[1].

Inhibiting acetyltransferases CBP/P300 by TPOP146 (134 nM) or PCAF by L-45 (126 nM) for 24 h did not significantly decrease the K49-acetylated b-cat level in Tau-overexpressing N2a cells (n = 3 biological replicates each group)
Solvent & Solubility
DMSO : 21.43 mg/mL (44.50 mM; ultrasonic and warming and heat to 60°C; 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, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

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: 2.14 mg/mL (4.44 mM); Clear solution; Need ultrasonic
This protocol yields a clear solution of 2.14 mg/mL.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (21.4 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: 2.14 mg/mL (4.44 mM); Clear solution; Need ultrasonic
This protocol yields a clear solution of 2.14 mg/mL.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (21.4 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.
Protocol
Proteins are buffered in 10 mM HEPES, pH 7.5, 500 mM NaCl and assayed in a 96-well plate at a final concentration of 2 μM in 20 μL volume. Compounds (TPOP146) are added at a final concentration of 10 μM. SYPRO Orange (Molecular Probes) is added as a fluorescence probe at a dilution of 1:1000. Excitation and emission filters for the SYPRO Orange dye are set to 465 and 590 nm, respectively. The temperature is raised with a step of 3°C per minute from 25 to 96°C, and fluorescence readings are taken at each interval[1].
