9-Hydroxycanthin-6-one
9-Hydroxycanthin-6-one is a β-carboline alkaloid. 9-Hydroxycanthin-6-one can be isolated from the roots of E. longifolia. 9-Hydroxycanthin-6-one inhibits TNF-α-induced activation of the NF-κB pathway. 9-Hydroxycanthin-6-one activates GSK3β independently of CK1α, drives phosphorylation and degradation of β-catenin, and inhibits the Wnt signaling pathway. 9-Hydroxycanthin-6-one exerts selective cytotoxicity against Wnt-dependent colon cancer cells. 9-Hydroxycanthin-6-one can be used in studies related to colon cancer.

In Vitro
9-Hydroxycanthin-6-one (3.8-30 μM; 30 min pretreatment, 4 h TNF-α stimulation) potently inhibits TNF-α-induced NF-κB activation in HEK-293/NF-κB-luc cells with an IC50 of 3.8 μM, and exhibits no cytotoxicity at 30 μM[1].
9-Hydroxycanthin-6-one (5-20 μM; 24 h) potently and selectively inhibits TCF/β-catenin transcriptional activity in STF/293 cells with an IC50 of 6.8 μM, while preserving high cell viability[2].
9-Hydroxycanthin-6-one (24 h) selectively inhibits the viability of Wnt-dependent human colon cancer cells (SW480, HCT116) with IC50 values of 17.4 μM and 30.0 μM, respectively, while sparing Wnt-independent and noncancer cell lines[2].
9-Hydroxycanthin-6-one (10-30 μM; 24 h) dose-dependently reduces total β-catenin levels (in whole cell, cytosolic, and nuclear fractions) and increases β-catenin phosphorylation at GSK3β target sites (Ser33/Ser37/Thr41) in SW480 cells, without altering CK1α-mediated β-catenin phosphorylation or total GSK3β/CK1α levels[2].
9-Hydroxycanthin-6-one (30 μM; 24 h post-siRNA transfection) inhibits Wnt signaling in SW480 cells through GSK3β activation independent of CK1α, as it reduces β-catenin and increases GSK3β-mediated β-catenin phosphorylation even when CK1α is knocked down[2].

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 1 mg/mL (4.23 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 1 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (10.0 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.
