ETTAC-2
Based on 1 Customer Validation
ETTAC-2 is a LRG1 PROTAC degrader, degrading LRG1 via the ubiquitin-proteasome pathway with a DC50 value of 8.38 μM. ETTAC-2 penetrates damaged renal cells to reduce the extracellular secretion of LRG1. ETTAC-2 effectively inhibits the TGF-β-Smad3 signaling pathway and diminishes the secretion of fibrosis-associated extracellular matrix proteins. ETTAC-2 degrades LRG1 within fibrotic kidneys and the efficacy in inhibiting the TGF-β-Smad3 pathway both in vitro and vivo. ETTAC-2 can be used for renal fibrosis research.

LRG1 8.38 μM (DC50) |
ETTAC-2 (0-26μM, 1-48 h) induces LRG1 degradation with an DC50 value of 8.38 μM in a time-dependent manner, which degradation can persist for 6 h in HK-2 cells via the ubiquitin-proteasome pathway[1].
ETTAC-2 alleviates cellular fibrosis in vitro by inhibiting the TGF- β-Smad3 pathway in HK-2 cells[1].

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 (1.32 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 (1.32 mM); Clear solution
