Biological Activity


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. PROTACs target and selectively degrade target proteins by taking advantage of the intracellular ubiquitin-proteasome system.

Solubility Data


Solubility (In Vitro) DMSO : ~100 mg/mL (~256.81 mM)
Solubility (In Vivo) Solubility in Formulation 1: ≥ 2.5 mg/mL (6.42 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 25.0 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: ≥ 2.5 mg/mL (6.42 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 25.0 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.

Solubility in Formulation 3: ≥ 2.5 mg/mL (6.42 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (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 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.

Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 2.5681 mL 12.8403 mL 25.6805 mL
5 mM 0.5136 mL 2.5681 mL 5.1361 mL
10 mM 0.2568 mL 1.2840 mL 2.5681 mL
*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.
