Description

BTX-A51 (Casein Kinase inhibitor A51) is a potent and orally active casein kinase 1α (CK1α) inhibitor. BTX-A51 induces leukemia cell apoptosis, and has potent anti-leukemic activities[1].

IC50 & Target[1]

CKIα

 

CDK7

1.3 nM (Kd)

CDK9

4 nM (Kd)

In Vitro

Similar to CKIα depletion, BTX-A51 (0.05-3.2 μM; 18 hours) treatment of RKO cells abolished most of the Ser45 phosphorylation signal and the consecutive GSK3 phosphorylation cascade resulting in stabilization of β-catenin[1].
BTX-A51 is highly effective in inducing leukemia cell apoptosis at 160 nM or lower, mostly in correlation to their capacity to stabilize p53[1].
BTX-A51 (0.08-2 μM; 6.5 hours) abolishes the expression of MYC, MDM2, and the anti-apoptotic oncogene MCL1. BTX-A51 induces a marked reduction in mRNA expression of MYC and MDM2, yet upregulates the expression of the Wnt targets AXIN2 and CCND1 (Cyclin D1)[1].

Cell Viability Assay[1]

Cell Line: MV4-11 cells
Concentration: 0.08 μM, 0.6 μM, 2 μM
Incubation Time: 6.5 hours
Result: Abolishes the expression of MYC, MDM2, and the anti-apoptotic oncogene MCL1.
In Vivo

Oral treatment is initiated at 8 days (BTX-A51; 5 mg/kg/day) after leukemia cell inoculation, at which the percentage of leukemia cells in the BM is more than 1.5% of all cells. all A51-treated mice have normal organ morphology and histology and normal blood counts[1].
Pharmacokinetic studies of the inhibitor BTX-A51 at 20 mg/kg reveal rapid oral absorption with a Tmax of 0.5-2 hr, Cmax of 1060 ng/mL, T1/2 of 2.5 hr, and area under the curve (AUC) values of 3680 (ng*hr/mL)[1].

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 (6.93 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.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (6.93 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 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.

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.
