SCH529074 is a potent and orally active p53 activator. SCH529074 binds specifically and conformation-dependently to p53 DBD ( DNA binding domain) with a Ki of 1-2 μM in a saturable manner. SCH529074 restores mutant p53 function and interrupts HDM2-mediated ubiquitination of wild Type p53. SCH529074 can be used for the study of non-small-cell lung carcinoma (NSCLC).

Description

SCH529074 is a potent and orally active p53 activator. SCH529074 binds specifically and conformation-dependently to p53 DBD ( DNA binding domain) with a Ki of 1-2 μM in a saturable manner. SCH529074 restores mutant p53 function and interrupts HDM2-mediated ubiquitination of wild Type p53. SCH529074 can be used for the study of non-small-cell lung carcinoma (NSCLC)[1][2].

IC50 & Target

Ki: 1-2 μM (p53 DBD)[2]
In Vitro

SCH529074 (2-4 µM; 24 hours) causes significant reduction in cell viability, it causes a significant decreasing to 20-25% in p53 mutant cells (H157, H1975 and H322) and to 68% in the p53 WT cell line A549 at 4 µM[1].
SCH 529074 (2 and 4 µM) induces NSCLC cells (H157, A549, HCT116 and HCT116 p53-/-) arrested at the G0/G1 phase (59%; 72%; 66%; and 57%) compared with the control cells following low concentration (2 µM) of treatment[1].
SCH 529074 (2-4 µM; 24 hours) induces the early and late apoptotic rates at 2 µM in H1975 cells. In H157 cells, SCH 529074 treatment induces early and late apoptosis. Similarly, in A549 cells, 2 and 4 µM of SCH 529074 significantly increased early and late apoptosis. In line with that, in colon cancer cells, in HCT116 cells, 4 µM of SCH 529074 causes a significant induction of early and late apoptosis, and 4 µM of SCH 529074 significantly induces early apoptosis in HCT116 p53-/- cells[1].
SCH 529074 (2-6 µM; 24 hours) increases the protein levels of PUMA and p21 revealed to 4 or 6 µM in the cancer cell lines regardless of their p53 status[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: ≥ 1 mg/mL (1.77 mM); Clear solution

    This protocol yields a clear solution of ≥ 1 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (10.0 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: ≥ 1 mg/mL (1.77 mM); Clear solution

    This protocol yields a clear solution of ≥ 1 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 (10.0 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.
