Indirubin-3′-oxime  (Synonyms: IDR3O; I3O)

Cat. No.: HY-139254 Purity: 99.10%
Handling Instructions Technical Support

Indirubin-3′-oxime (IDR3O), a synthetic derivative of indirubin, is a potent inhibitor of cyclin-dependent kinases (CDKs) and glycogen synthase kinase 3β (GSK3β). Indirubin-3′-oxime directly inhibits the activity of all three isoforms of JNK (JNK1, JNK2, and JNK3), with IC50s of 0.8 μM, 1.4 μM, and 1.0 μM, respectively. Indirubin-3′-oxime can enhance height growth via activation of Wnt/β-catenin signaling in chondrocytes.

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    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (9.02 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.

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.
