COA Handling Instructions

Eprenetapopt (APR-246) is a first-in-class, small molecule that restores wild-type p53 functions in TP53-mutant cells. Eprenetapopt triggers apoptosis in tumor cells. Eprenetapopt also targets the selenoprotein thioredoxin reductase 1 (TrxR1), a key regulator of cellular redox balance.

Description

Eprenetapopt (APR-246) is a first-in-class, small molecule that restores wild-type p53 functions in TP53-mutant cells. Eprenetapopt triggers apoptosis in tumor cells. Eprenetapopt also targets the selenoprotein thioredoxin reductase 1 (TrxR1), a key regulator of cellular redox balance[1][2][3].

IC50 & Target

p53 activator[1]
TrxR1 inhibitor[1]

In Vitro

Eprenetapopt inhibits both recombinant TrxR1 in vitro and TrxR1 in cells. Cellular TrxR1 activity is inhibited by Eprenetapopt irrespective of p53 status. Eprenetapopt can directly affect cellular redox status via targeting of TrxR1. Several small molecules have been shown to restore wild-type activity to mutant p53, including CP-31398, PRIMA-1 and Eprenetapopt, MIRA, STIMA, PhiKan-083 and NSC319726. PRIMA-1 and its methylated analog Eprenetapopt promote correct folding of mutant p53, induce cell death by apoptosis, and inhibit tumor growth in mice. Eprenetapopt has also been shown to reactivate mutant forms of the p63 and p73 proteins that share high structural homology with p53[1].
Eprenetapopt is a powerful apoptosis-inducing agent. Eprenetapopt can enhance apoptosis in mutant p53 carrying cells, compared to the p53 null parental cells. Most p53 mutants are in complex with Hsp70 proteins. Eprenetapopt treatment increases Hsp70 expression and nucleolar translocation, in parallel with the induction of nucleolar accumulation of mutant p53. Several lines of evidence suggest that Eprenetapopt can also act independently of the p53 status of the cell. It can radiosensitize prostate carcinoma cell lines with mutant or wild type p53 and p53-/- cells as well. Introduction of mutant p53 (p53ser249 or p53gln248) into p53-/- hepatocarcinoma cells increases sensitivity to Eprenetapopt without the induction of p53 target genes.Eprenetapopt regularly induces apoptosis in mutant p53 expressing cells[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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (12.55 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 (12.55 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.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.

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.
