ZX079
ZX079 is a dual BRD4 and CBP PROTAC degrader with a BRD4 DC50 value of 0.035 nM and a CBP DC50 value of < 0.02 nM. ZX079 induces dose- and time-dependent degradation of BRD4 and CBP proteins through recruitment of the cereblon E3 ligase. ZX079 induces apoptosis in MV4-11 and MOLM-13 cells, reduces tumor growth in an acute myeloid leukemia xenograft model. ZX079 can be used for the research of acute myeloid leukemia.

In Vitro
ZX079 (10k) (24 h) exhibits dose- and time-dependent degradation of BRD4 (DC50 = 0.035 nM), CBP, p300 and BRD3 (DC50 < 0.02 nM) without significant degradation of BRD2[1].
ZX079 (0.0001-100 μM) binds potently to BRD4 (1) (IC50 = 0.9 μM), BRD4 (2) (IC50 = 0.5 μM), and CBP bromodomains (IC50 = 1.2 μM) and effectively promotes BRD4-PROTAC-CRBN and CBP-PROTAC-CRBN ternary complex assembly[1].
ZX079 (0.02-200 nM; 96 h) exerts superior antiproliferative activity against MV4-11 cells (IC50 = 0.86 nM) and MOLM-13 cells, while it shows minimal cytotoxicity against normal HUVEC and L929 cells (tested at 0.001-10 μM)[1].
ZX079 (200 nM; 8 h) selectively depletes BRD4, BRD3, CBP, and p300 proteins in MV4-11 cells at the proteome-wide level.
ZX079 (37-1000 nM; 48 h) induces apoptosis in MV4-11 and MOLM-13 cells in a dose-dependent manner, accompanied by increased cleavage of Caspase-3 and almost complete reduction of c-Myc protein expression at 2 nM[1].

Solvent & Solubility
In Vitro:
DMSO : 100 mg/mL (112.61 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
In Vivo:
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 (2.82 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 (2.82 mM); Clear solution
