SF2523 treatment decreases protein levels of MYCN and Cyclin D1, the MYCN target, and inhibits AKT activation by blocking phosphorylation of AKT at Ser473. SF2523 treatment leads to the displacement of BRD4 from both MYCN promoter sites. SF2523 interacts robustly with the full-length BRD4 (Kd=140 nM) and exhibits comparable affinity to the BRD4 first BD (BD1) (Kd=150 nM), however it binds more weakly to the second BD (BD2) of BRD4 (Kd=710 nM). Comparison of binding affinities of SF2523 for BDs of other proteins reveal that it binds equally well to BDs of BRD4, BRD2, and BRD3; shows moderate binding to BDs of CECR2 and BRDT; but associates much weaker with other BDs[2].

Solvent & Solubility
DMSO : ≥ 30 mg/mL (80.77 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" means soluble, but saturation unknown.
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: ≥ 2.5 mg/mL (6.73 mM); 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (6.73 mM); 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 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.

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
Mice: After 20 d of tumor implantation, mice are treated with either (i) 30 mg/kg of SF2523 formulated in 15% DMA+30% captisol, (ii) 30 mg/kg of JQ1 formulated in 30% captisol in combination with 30 mg/kg of BKM120 formulated in 15% ethanol+15% cremaphore, (iii) vehicle (15% ethanol+15% cremaphore, as control), or (iv) another vehicle (15% DMA+30% captisol, as control) five times a week, until tumors are removed on day 35[2].
