Description

Brigimadlin (BI 907828) is an orally active E3 ubiquitin-protein ligase MDM-2 inhibitor, preventing MDM-2 from negatively regulating the tumor suppressor p53. Brigimadlin can be used for antineoplastic research[1][2][3][4].

In Vitro

Brigimadlin (0-10 nM, 48 h) inhibits viability and induces cell death in brain tumor stem cells (BTSCs)[3].
Brigimadlin (1-50 nM, 48 h) induces apoptosis and increases p53 transcriptional targets (p21 and PUMA) in BT48, BT67, BT73 cells[3].
Brigimadlin (1 nM, 48 h) disrupts the interaction between MDM2 and wild-type p53 in brain tumor stem cells (BTSCs)[3].

In Vivo

Brigimadlin (15 and 50 mg/kg, p.o., once a week) inhibits tumor growth and increases median survival in orthotopic xenografts of both a MDM2 amplified (BT48) and a normal CN (BT67), TP53 wild-type BTSC model[3].
Brigimadlin (50 mg/kg, p.o., a single dose) increasees PD biomarkers (CDKN1a and GDF15) in the brain in orthotopic GBM patient-derived BTSC models (BT48 and BT67) in SCID mice, and has low systemic clearance[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    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 1.25 mg/mL (2.11 mM); Clear solution

    This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 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: ≥ 1.25 mg/mL (2.11 mM); Clear solution

    This protocol yields a clear solution of ≥ 1.25 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 (12.5 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.
