Licochalcone B inhibits amyloid β (42) self-aggregation (IC50=2.16 μM) and disaggregate pre-formed Aβ42 fibrils, reduce metal-induced Aβ42 aggregation through chelating metal ionsLicochalcone B inhibits phosphorylation of NF-κB p65 in LPS signaling pathway. Licochalcone B inhibits growth and induces apoptosis of NSCLC cells. Licochalcone B specifically inhibits the NLRP3 inflammasome by disrupting NEK7‐NLRP3 interaction.

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 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (7.27 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
