KB02-JQ1
Based on 4 publication(s) in Google Scholar
KB02-JQ1 is a potent and selective BRD4 PROTAC degrader. KB02-JQ1 degrades BRD4 via the ubiquitin-proteasome pathway by bridging DCAF16 E3 ubiquitin ligase and BRD4. KB02-JQ1 can be used for cancer research.
(Pink: BRD4 ligand (HY-78695); Blue: DCAF16 ligand (HY-131385); Black: linker (HY-128833)).

In Vitro
KB02-JQ1 (4-40 μM) induces concentration-dependent proteasomal degradation of endogenous BRD4 in HEK293T cells, whereas KB02 alone, JQ1 alone, and their combination do not exhibit this effect[1].
KB02-JQ1 (20 μM; 2 h) promotes the formation of a complex between BRD4 and high-molecular-weight covalently modified HA-DCAF16 in HEK293T cells co-transfected with BRD4-FLAG and HA-DCAF16[1].
KB02-JQ1 (40 μM; 24 h) induces BRD4 degradation in DCAF16+/+ HEK293 cells, but this effect is significantly blocked in DCAF16-/- cells, indicating that its degradation effect is dependent on DCAF16[1].
KB02-JQ1 (incubation for 24 h) has minimal effect on HEK293T cell viability, with an IC50 > 50 μM[1].
KB02-JQ1 (20 μM; 1.5 h) produces approximately 40% covalent binding with DCAF16 (C173/177-179 peptide) in HEK293T cells[1].
KB02-JQ1 (20 μM; 24 h) selectively decreases BRD4 and ACAT1 protein abundance and stabilizes BRD2 protein abundance in SILAC-labeled HEK293T cells[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Solvant et solubilité
In Vitro:
DMSO : 100 mg/mL (125.51 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; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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: ≥ 5 mg/mL (6.28 mM); Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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: 5 mg/mL (6.28 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 5 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 (50.0 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.
