Description

NRX-252114 is a potent enhancer of the interaction between β-catenin, and its cognate E3 ligase, SCFβ-TrCP. NRX-252114 enhances the binding of pSer33/S37A β-catenin peptide for β-TrCP with an EC50 of 6.5 nM and a Kd of 0.4 nM. NRX-252114 induces mutant β-catenin degradation[1].

IC50 & Target

EC50: 6.5 nM (β-catenin:β-TrCP Interaction)[1]
Kd: 0.4 nM (β-catenin:β-TrCP Interaction)[1]

In Vitro

NRX-252114 (20 μM) enhances the binding of pSer33/S37A β-catenin peptide for β-TrCP, with more than 1500-fold co-operativity[1].
NRX-252114 (0-25 μM) increases the ubiquitylation of pSer33/S37A β-catenin peptide to form long ubiquitin chains[1].
NRX-252114 (0-25 μM) enhances the ubiquitylation of S33E/S37A β-catenin protein, as well as unphosphorylated Ser33/S37A β-catenin peptides[1].
NRX-252114 (20 μM, 6 h) results in robust S33E/S37A β-catenin:β-TrCP interaction in the transfected HEK293T cells[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 (4.90 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% Corn Oil

    Solubility: 2.5 mg/mL (4.90 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.5 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 (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

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.
