Isoliquiritigenin (also known as ISL; GU17; Isoliquiritigen) is a naturally occuring chalcone compound and NLRP3 antagonist found in licorice root and several other plants that displays antioxidant, anti-inflammatory, and antitumor activities as well as hepatoprotection against steatosis-induced oxidative stress. Isoliquiritigenin is a soluble guanylyl cyclase activator with antitumor activity.
| ln Vitro |
By blocking sorbitol buildup in human erythrocytes (IC50=2.0 μM) and rat lens aldose reductase (IC50=320 nM), isoliquiritigenin can avoid diabetic consequences [1]. In cardiomyocytes, hypoxia-induced TPS and TR90 prolongation is markedly inhibited by isoliquiritigenin (100 μM). In comparison to the vehicle group, isoliquiritigenin dramatically increased AMPK Thr172 phosphorylation. Cardiomyocytes treated with isoliquiritigenin also triggered the extracellular signal-regulated kinase (ERK) signaling pathway. During hypoxia/reoxygenation, isoliquiritigenin administration can dramatically lower intracellular ROS levels in isolated cardiomyocytes [3]. Isoliquiritigenin not only downregulates IL-6 expression, but also drastically lowers the levels of phosphorylated ERK and STAT3, and suppresses the phosphorylation levels of ERK and STAT3 caused by recombinant human IL-6, which are critical signals in the IL-6 signal regulatory network. protein[4].

When different stimulants such CCh (1 mM), KCl (60 mM), and BaCl2 (0.3 mM) are used to generate tetanic contractions in the mouse jejunum, isoliquiritigenin exhibits concentration-dependent suppression of those contractions. 4.96±1.97 mM, 4.03±1.34 mM, and 3.70±0.58 mM are the respective IC50 values[2]. In MM xenograft models, isoliquiritigenin demonstrates strong anti-tumor activity and synergistically increases doxorubicin's anti-myeloma efficacy [4].

Solubility in Formulation 1: ≥ 2.5 mg/mL (9.76 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.

*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.
