Astringin
Based on 1 Customer Validation
Astringin (trans-Astringin) is an orally active natural phenolic stilbene glucoside. Astringin can inhibit the production of oxidative stress, inflammatory factors, etc. Astringin has multiple activities such as anti-oxidation, anti-inflammation, and anti-apoptosis. Astringin is also an inhibitor of ferroptosis. Astringin can be used in the research of diseases such as acute lung injury.

Astringin (0-75 µg/mL; 0-26 h) enhances cell viability, inhibits apoptosis, and suppresses the elevation of ROS and MDA levels as well as the production of inflammatory factors such as TNF-α, IL-1β, and IL-6 in LPS (HY-D1056)-stimulated A549 cells. The mechanism involves the inhibition of the PI3K/AKT/NF-κB pathway[1].
Astringin (1-100 µM) inhibits lipid peroxidation in Erastin (HY-15763)-treated bone marrow-derived mesenchymal stem cells[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:LPS (HY-D1056) treated A549 cells
-
Concentration:0, 25, 50 and 75 µg/mL
-
Incubation Time:Pretreated with 1 h, then co-incubation for 24 h
-
Result:Increased the cell viability in a dose-dependent manner.

Animal Model:Male albino rats (Rattus norvegicus, strain: Sprague Dawley, weight: 205±10 g, age: 13-14 weeks) were treated with chromium (15 mg/kg) to induce nephrotoxicity[1]
-
Dosage:10 mg/kg
-
Administration:Oral gavage; 4 weeks
-
Result:Significantly restored biochemical parameters (reduced levels of ROS, MDA, inflammatory cytokines, and apoptotic markers; increased activities of antioxidant enzymes).
Improved renal function (lowered levels of cystatin C, BUN, creatinine, etc.).
Alleviated histological impairments (such as endothelial swelling, tubular dilation) in chromium-intoxicated rats.
Inhibited TLR4/MyD88, HMGB1/RAGE, and NF-κB pathways.

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: ≥ 1.25 mg/mL (3.08 mM); Clear solution
This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 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.

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
