BETd-260 (ZBC260; Compound 23) is capable of inducing degradation of BRD2, BRD3, and BRD4 proteins at 30–100 pM in the RS4;11 leukemia cells. BETd-260 shows inhibitory activity against the growth of RS4;11 leukemia cells and MOLM-13 cells with IC50s of 51 pM and 2.2 nM, respectively, and induces apoptosis in both RS4;11 and MOLM-13 cell lines at 3-10 nM[1].
BETd-260 reciprocally modulates the expression of several apoptotic genes in HCC cells, i.e., suppressing the expression of anti-apoptotic Mcl-1, Bcl-2, c-Myc, and XIAP, whereas increasing the expression of pro-apoptotic Bad[2].

Solvent & Solubility
DMSO : 25 mg/mL (31.29 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 (protect from light, stored under nitrogen). When stored at -80°C, please use it within 6 months.

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: ≥ 0.83 mg/mL (1.04 mM); Clear solution
This protocol yields a clear solution of ≥ 0.83 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (8.3 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.

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
In cell growth experiments, cells are seeded in 96-well cell culture plates at a density of 10000−20000 cells/well in 100 μL of culture medium. BETd-260 is serially diluted in the appropriate medium, and 100 μL of the diluted solution containing BETd-260 is added to the appropriate wells of the cell plate. After addition of BETd-260, the cells are incubated for 4 days at 37°C in an atmosphere of 5% CO2. Cell growth is evaluated by a lactate dehydrogenase-based WST-8 assay using a multimode microplate reader. The WST-8 reagent is added to the plate, incubated for at least 1 h, and read at 450 nm. The readings are normalized to the DMSO-treated cells, and the IC50 is calculated by nonlinear regression analysis using GraphPad Prism 6 software[1].

Mice[1]
To develop xenograft tumors, 5 × 106 RS4;11 cells with 50% Matrigel are injected subcutaneously on the dorsal side of severe combined immunodeficient (SCID) mice, one tumor per mouse. When tumors reach appr 100 mm3, mice are randomly assigned to BETd-260 treatment and vehicle control groups. Animals are monitored daily for any signs of toxicity and weighed 2-3 times per week during the treatment and weighed at least weekly after BETd-260 treatment end. Tumor size is measured 2-3 times per week by electronic calipers during the treatment period and at least weekly after the treatment is end. Tumor volume is calculated as V = LW2/2, where L is the length and W is the width of the tumor[1].
