FL-411 is a selective BRD4 inhibitor. Binding affinities of FL-411 are measured by TR-FRET against the first and second bromodomains of BRD2(1), BRD4(1), and BRD4(2) with IC50s of 24.60±0.70 μM, 0.47±0.02 μM, 0.93±0.05 μM, respectively. FL-411 possesses a good BRD4(1) inhibition activity (IC50=0.43±0.09 μM), antiproliferative activity (MCF-7, IC50=1.62±0.06 μM; MDA-MB-231, IC50=3.27±0.14 μM), and autophagic activity (42.29% in MCF-7 cells), as well as displays a low toxicity against MCF10A cells). FL-411 induces ATG5-dependent autophagy-associated cell death (ACD) by blocking BRD4-AMPK interaction and thus activating AMPK-mTOR-ULK1-modulated autophagic pathway in breast cancer cells[1].

Solvent & Solubility
DMSO : 5.4 mg/mL (15.82 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, 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 90% (20% SBE-β-CD in Saline)
Solubility: 1.25 mg/mL (3.66 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 1.25 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 0.54 mg/mL (1.58 mM); Clear solution
This protocol yields a clear solution of ≥ 0.54 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.4 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.

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
The MCF-7 and MDA-MB-231 cells are dispensed in 96-well flat bottom microtiter plates at a density of 5×104 cells/mL. After 24 h incubation, MCF-7 or MDA-MB-231 cells are treated with 1.5 and 3 μM FL-411, respectively. 3-MA (1 mM) is added 1 h before treated with FL-411. After treatment, cell viability is measured by the MTT assay. 5 mg/mL MTT is added to each well. After 4 h incubation, the medium is removed and 150 μL of DMSO is added to each well to dissolve the crystal formazan dye. Absorbance is measured at 570 nm on an enzyme-linked immunosorbent assay reader[1].

Mice[1]
52 female nude mice (BALB/c, 6-8 weeks, 20-22 g) are injected subcutaneously with MCF-7 cells or MDA-MB-231 cells (5×106 cells/mouse), respectively. When the tumors reach 100 mm3 in volume, the mice are divided into four groups for each cell line. Three groups are treated with different doses of FL-411 (low dose, 25 mg/kg; median dose, 50 mg/kg; high dose, 100 mg/kg) once a day by intragastric administration for 24 or 27 days, whereas the control group is treated with vehicle control. During the treatment, the tumor volumes and body weight are measured every 3 days until the end of the study. At the end of treatment, all mice are sacrificed. The tumor tissues are harvested, weighed, and photographed. Then, the tumor tissues are frozen in liquid nitrogen or fixed in formalin immediately[1].
