Description

MSN-50 is a Bax and Bak oligomerization inhibitor. MSN-50 efficiently inhibits liposome permeabilization, prevents genotoxic cell death and promotes neuroprotection[1][2].

IC50 & Target

Bax

 

Bak

 

In Vitro

MSN-50 (0~10 uM) inhibits dye release from liposomes in a concentration-dependent fashion. MSN-50 (0~40 uM) inhibits tBid/Bax-mediated MOMP (mitochondrial outer membrane permeabilization) in a concentration-dependent manner and shows concentration-dependent inhibition of Bak-mediated MOMP. MSN-50 inhibits both Bax and Bak after activation by either cBid or Bim. MSN-50 (5 μM; BMK cells) inhibits apoptosis induced by actinomycin D and staurosporin (STS)[1][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    90% (20% SBE-β-CD in Saline)

    Solubility: 5 mg/mL (7.26 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 5 mg/mL (7.26 mM); Clear solution

    This protocol yields a clear solution of ≥ 5 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 (50.0 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.
