Rezatapopt (PC14586) is an orally active antineoplastic agent. Rezatapopt binds to a pocket created by the TP53 Y220C mutation. Rezatapopt restores p53 tumor suppressor functions by stabilization of the p53 protein structure. Rezatapopt demonstrates tumor inhibition and regression in mouse models with established human tumor xenografts harboring the TP53 Y220C mutation.

    Description

    Rezatapopt (PC14586) is an orally active antineoplastic agent. Rezatapopt binds to a pocket created by the TP53 Y220C mutation. Rezatapopt restores p53 tumor suppressor functions by stabilization of the p53 protein structure. Rezatapopt demonstrates tumor inhibition and regression in mouse models with established human tumor xenografts harboring the TP53 Y220C mutation[1][2][3][4].

    In Vivo

    Rezatapopt induces complete regression of tumors in mice and potentiated checkpoint therapy[3].

    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    90% (20% SBE-β-CD in Saline)

      Solubility: ≥ 2.5 mg/mL (4.58 mM); Suspended solution

      This protocol yields a suspended solution of ≥ 2.5 mg/mL (saturation unknown). 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 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.
