ln Vitro |
Licochalcone D (10 μM; 1 h) significantly inhibits LPS-induced iNOS expression and NO production by blocking the phosphorylation and transactivation of NF-κB p65, which in turn inhibits LPS-induced protein regulatory A (PKA) activation. This indicates that Licochalcone D (10 μM; 24 h) negatively regulates lipopolysaccharide (LPS)-induced NF-κB activation. Proliferation of melanoma cells inhibits A375 cell migration, lowers the potential of the mitochondrial membrane, and raises ROS generation in A375 cells [2]. Licochalcone D (0–25 μM; 24 h) decreases MMP-2 and A375 cell migration as well as sterility.

ln Vivo |
In a xenograft model of oncinoblastoma B16F0 cells, licochalcone D (25 and 50 mg/kg; ig; once daily for one week) reduces the formation of tumors [2].
licochalcone D (LD) inhibits the tumor growth in a mouse xenograft model of murine melanoma B16F0 cells Based on the findings that LD induced A375 cell apoptosis in vitro, we used B16F0 tumor models to measure whether LD could suppress tumor progression in vivo. C57BL/6 mice bearing melanoma B16F0 cell-derived tumors were used as an in vivo model to evaluate the effects of LD. Compared with the control group, the tumor growth rates were obviously lower in mice treated with LD. The tumor growth inhibition rates were calculated to be 32.0 and 54.1% in the LD-treated groups (25 and 50 mg/kg), respectively (Fig. 9A and B)[2]. |
Enzyme Assay |
Licorice root has been used as a traditional medicine for the treatment of gastric ulcer, bronchial asthma and inflammation. Licochalcone A is a major component of Xinjiang licorice, Glycyrrhiza inflata. Previously we showed that Licochalcone A significantly inhibited LPS-induced NF-kappaB transcriptional activation by abrogating the phosphorylation of NF-kappaB p65 at serine 276. Glycyrrhiza inflata contains not only Licochalcone A but also Licochalcone B, Licochalcone C, Licochalcone D, Echinatin and Isoliquiritigenin, harboring the common structure of chalcones. No chalcones had any effect on LPS-induced IkappaB degradation, nuclear translocation and DNA binding activity of NF-kappaB p65; however, we observed that Licochalcone B and Licochalcone D significantly inhibited LPS-induced phosphorylation at serine 276 and transcriptional activation of NF-kappaB, the same as Licochalcone A. Interestingly, we also found that Licochalcone A, Licochalcone B and Licochalcone D effectively inhibited LPS-induced activation of PKA, which is required for the phosphorylation of NF-kappaB p65 at serine 276. Consequently, Licochalcone B and Licochalcone D significantly reduced the LPS-induced production of NO, TNFalpha and MCP-1. On the other hand, Licochalcone C, Echinatin and Isoliquitigenin failed to inhibit LPS-induced NF-kappaB activation. These findings suggest that the anti-inflammatory effect of Glycyrrhiza inflata is ascribable to the potent inhibition of NF-kappaB by Licochalcone A, Licochalcone B and Licochalcone D[1].

Solubility in Formulation 1: ≥ 2.08 mg/mL (5.87 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 20.8 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. Solubility in Formulation 2: ≥ 2.08 mg/mL (5.87 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in 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 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.  (Please use freshly prepared in vivo formulations for optimal results.) |

*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.
