Yangonin is one of pepper's six primary kavalactones. By suppressing NF-κB RelA/p65 subunit transcription, yangonin efficiently prevents NF-κB activation. The NF-κB reporter gene's induced expression is substantially suppressed by yangonin. Yangonin, however, does not obstruct p65 nuclear translocation, TNF-α-induced inhibitor of κBα (IκBα) degradation, or NF-κB's DNA-binding activity. Yangonin suppresses RelA/p65's transactivation activity in addition to the NF-κB activation brought on by RelA/p65 overexpression. Yangonin dramatically reduces the activation of ERK 1/2 and stress-activated protein kinase/JNK, but does not decrease TNF-α-induced p38 activation [2].

| Solubility (In Vitro) |
DMSO : ~25 mg/mL (~96.80 mM)
|
|---|---|
| Solubility (In Vivo) |
Solubility in Formulation 1: 2.5 mg/mL (9.68 mM) in 10% DMSO + 40% PEG300 +5% Tween-80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication.
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. (Please use freshly prepared in vivo formulations for optimal results.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 3.8719 mL | 19.3596 mL | 38.7192 mL | |
| 5 mM | 0.7744 mL | 3.8719 mL | 7.7438 mL | |
| 10 mM | 0.3872 mL | 1.9360 mL | 3.8719 mL |
*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.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
