Description

TAK-441 is a highly potent and orally active hedgehog (Hh) signaling inhibitor with an IC50value of 4.4 nM. TAK-441 has strong antitumor activity in solid tumors[1][2][3].

IC50 & Target

IC50: 4.4 nM (Gli-luc reporter)[1]
In Vitro

TAK-441 (compound 11d) (0.03–1000 nM, 48 h) has potent activity in the Gli-luc reporter with an IC50 value of 4.4 nM and good solubility[1].
TAK-441 (0.03–1000 nM, 48 h) inhibits Gli1 mRNA with IC50 values of 0.0457 and 0.113 mg/ml in the tumor and skin, respectively[1].
TAK-441 (0.5-500 nM, 48-72 h) does not affect androgen withdrawal-induced Shh up-regulation or viability of LNCaP cells[3].
TAK-441 (0.5-500 nM, 48-72 h) leads to delayed castration-resistant progression of LNCaP xenografts by disrupting paracrine Hh signaling with the tumor stroma[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    40% PEG300    5% Tween-80    45% Saline

    Solubility: 2.5 mg/mL (4.34 mM); Clear solution; Need ultrasonic

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: 2.5 mg/mL (4.34 mM); Clear solution; Need ultrasonic

    This protocol yields a clear solution of 2.5 mg/mL. If the continuous dosing period exceeds half a month, please choose this protocol carefully.

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.
