VHL: von Hippel-Lindau protein

| ln Vitro |
One ligand is for an E3 ubiquitin ligase, and the other is for the target protein; these two ligands are joined by a linker to form PROTACs. The intracellular ubiquitin-proteasome system is utilized by PROTACs to specifically destroy target proteins[1].

| Additional Infomation |
The Bromo- and Extra-Terminal (BET) proteins BRD2, BRD3, and BRD4 are key regulators of transcription, epigenetics, and cancer, and serve as the targets of the pan-BET selective bromodomain inhibitor JQ1. However, the lack of selectivity among BET family members limits the utility of current inhibitors for target validation and may lead to off-target effects or toxicity in therapeutic applications. To address this, we designed Proteolysis-Targeting Chimeras (PROTACs) that link JQ1 to a ligand for the E3 ubiquitin ligase VHL, aiming to induce targeted degradation of BET proteins. One such compound, MZ1, potently and rapidly induces reversible, long-lasting, and unexpectedly selective degradation of BRD4 over BRD2 and BRD3. This activity is dependent on VHL binding and occurs at concentrations low enough to avoid stabilization of HIF-1α. Analysis of gene expression profiles of cancer-related genes responsive to JQ1 reveals that MZ1 induces a distinct and more restricted transcriptional response, consistent with selective suppression of BRD4. These findings open new avenues for exploring the cellular functions and therapeutic potential of selective BRD4 targeting. [1]

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 3.5 mg/mL (7.41 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 35.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 3.5 mg/mL (7.41 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 35.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: ≥ 3.5 mg/mL (7.41 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
