Activité biologique
PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
TGN-020 sodium (100 mg/kg; ip; single dose immediately followed SCI) promotes functional recovery at days 3, 7, 14, 21, and 28, as well as reduces the degree of edema and inhibits the expression of AQP4, GFAP, PCNA at days 3 after SCI[4].
TGN-020 sodium inhibits the glial scar formation and upregulates GAP-43 expression in adult female Sprague-Dawley rats (180-220 g, 9-10 weeks old) with SCI[4].

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 (21.91 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 (21.91 mM); Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
