In Vitro

Licochalcone B (IC50: 2.16 μM) inhibits self-mediated Aβ42 aggregation and disaggregates Aβ42 pre-formed fibrils[1].
Licochalcone B (0-12 μM, 48 h) reduces the ROS generation and protects cells from H2O2-induced cell death in SH-SY5Y cells[1].
Licochalcone B (10 μM, 1 h) inhibits LPS-induced NF-κB activation in RAW264.7 cells[2].
Licochalcone B (10 μM, 1 h) inhibits the LPS-induced phosphorylation of NF-κB p65 at serine 276, and inhibited the expression of TNFα and MCP-1[2].
Licochalcone B (0-20 μM, 24 or 48 h) inhibits human NSCLC cell growth[3].

In Vivo:

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.

  • Protocol 1

    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).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
