Customer Review

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.

In Vitro

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 Viability Assay^[1]

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.

In Vivo

Astringin (10 mg/kg; oral gavage; 4 weeks) can effectively alleviate chromium-induced oxidative stress, inflammation, apoptosis, and renal tissue damage in rats^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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.

Stock Solution Working Solution

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.

Protocol 1

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.

Protocol 2

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 1.25 mg/mL (3.08 mM); Clear solution

This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
