Harringtonolide
Based on 2 publication(s) in Google Scholar
Harringtonolide is a potent RACK1 inhibitor (IC50=39.66 μM in A375 cells). Harringtonolide inhibits the epithelial-mesenchymal transition (EMT) process and cell proliferation by affecting the interaction between FAK and RACK1. Harringtonolide has plant growth inhibitory, antiviral, anti-inflammatory, and antiproliferation activities.

Harringtonolide (0-50 μM; 24 hours) exhibits good antiproliferation activity in A375 cells with IC50 of 39.66 μM[1].
Harringtonolide (0-20 μM; 1 hour) restrains the proteolysis of RACK1 by Pronase, and protects temperature-dependent degradation of RACK1[1].
Harringtonolide (0-4 μM; 24 hours) suppresses the phosphorylation of FAK dose-dependently and inhibits Src and STAT3, the downstream proteins of FAK[1].
Harringtonolide (0-4 μM; 24 hours) dose-dependently inhibits the RACK1–FAK interaction in A375 cells[1].

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 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 0.5 mg/mL (1.61 mM); Clear solution
This protocol yields a clear solution of ≥ 0.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 0.5 mg/mL (1.61 mM); Clear solution
This protocol yields a clear solution of ≥ 0.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.0 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.
