Ailanthone is a potent inhibitor of both full-length AR (AR-FL) and constitutively active truncated AR splice variants (AR-Vs). Ailanthone binds to the co-chaperone protein p23 and prevents AR's interaction with HSP90, thus resulting in the disruption of the AR-chaperone complex followed by ubiquitin/proteasome-mediated degradation of AR as well as other p23 clients including AKT and Cdk4, and downregulates AR and its target genes in PCa cell lines and orthotopic animal tumours. In addition, Ailanthone blocks tumour growth and metastasis of CRPC[1].
Ailanthone has been shown to possess an growth-inhibitory effect against several cancer cell lines including HepG2, Hep3B, R-HepG2, Jurkat, HeLa, MCF-7, MDA-MB-231 and A549 cells. Ailanthone inhibits Huh7 cell growth through the induction of mitochondrion-mediated cell apoptosis and G0/G1 cell cycle arrest. Ailanthone-induced apoptosis is mitochondrion-mediated and involved the PI3K/AKT signaling pathway in Huh7 cells[2].

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: ≥ 2.08 mg/mL (5.53 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 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.

Protocol
For SRB assay, cells are cultured in complete RPMI 1640 and incubated with indicated concentrations of Ailanthone or cells are maintained in fresh phenol red-free RPMI 1640 medium with 5% charcoal-stripped FBS, 1 nM DHT and indicated compounds. After 48 or 72 h, the cells are then fixed and the cell growth is detected with the SRB assay. For colony formation assay, prostate cancer cells are incubated with indicated concentrations of Ailanthone in complete RPMI 1640 for 2 weeks and then cells are fixed with 4% paraformaldehyde and stained with crystal violet. Colonies are visualized under a microscope, and all of the fields are imaged and counted. Colony formation as a percentage of vehicle control for each cell line is presented[1].

Mice[1]
In orthotopic castration-resistant prostate cancer xenografts model, mice are intraperitoneally injected with Ailanthone (2 mg/kg), MDV (10 mg/kg) or DMSO (as controls). Prostate tumour growth and local metastasis are monitored weekly using the IVIS Imaging System. Images and measurements of bioluminescent signals are acquired and analysed using Living Image and Xenogen software[1].
