Description

NSC319726 (ZMC1) is a mutant p53R175 reactivator; inhibits growth of fibroblasts expressing the p53R175 mutation (IC50 = 8 nM); shows no inhibition for p53 wild-type cells.

IC50 & Target

IC50: 8 nM (mutant p53R175 reactivator)[1].
In Vitro

For NSC319726, the effect was even greater as the IC50 for the 175 mutant was 8 nM while the IC50 of the WT was not reached. NSC319726 did not induce WT p53 protein levels or transcriptional activity as common cytotoxic agents such as etoposide do in vitro. NSC319726 exhibited a much higher sensitivity for the MEF-p53R172H/R172H cell line as compared to the p53+/+ and p53-/- controls. NSC319726 treatment of a MEF cell line derived from p53R172H/R172H mice resulted in a loss of PAB240 immunoflouresence staining.

In Vivo

At a dose of 1mg/kg, tumor growth of the H460 (p53+/+) and MDAMB468 (p53R273W) xenografts was not inhibited relative to the vehicle control whereas tumor growth was significantly inhibited in the TOV112D (p53R175H) xenografts. When we lowered the dose ten-fold to 0.1 mg/kg in the TOV112D mice, we observed only a small difference in tumor growth inhibition demonstrating both a dosage effect of the drug and a larger therapeutic window.Taken together, these findings provide in vivo evidence for allele specific p53 mutant reactivation.

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: ≥ 2.08 mg/mL (8.88 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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: ≥ 2.08 mg/mL (8.88 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
