Description

Mepazine (Pecazine) is a potent and selective MALT1 protease inhibitor with IC50s of 0.83 and 0.42 μM for GSTMALT1 full length and GSTMALT1 325-760, respectively. Mepazine affects viability of ABC-DLBCL cells by enhancing apoptosis[1].

IC50 & Target

MALT1[1]
In Vitro

Mepazine (5-20 μM; 4 days) causes a decrease of cell viability in the activated B cell subtype of diffuse large B cell lymphoma (ABCDLBCL) cells, without significantly affecting GCB-DLBCL cells[1].

Cell Viability Assay[1]

Cell Line: ABC-DLBCL cell lines (HBL1, OCI-Ly3, U2932, TMD8, OCI-Ly10) and GCB-DLBCL cell lines (BJAB, Su-DHL-6, Su-DHL-4)
Concentration: 5, 10, and 20 μM
Incubation Time: 4 days
Result: Caused a decrease of cell viability in the ABC-DLBCL cells HBL1, OCI-Ly3, U2932, and TMD8, without significantly affecting GCB-DLBCL cells.
In Vivo

Mepazine (16 mg/kg; intraperitoneal administration) interferes with growth and induces apoptosis of ABC-DLBCL cell line OCI-Ly10 in NOD/scid IL-2Rgnull (NSG) mice with a murine DLBCL xenogeneic tumor model. Daily administration of Mepazine strongly impairs the expansion of the ABC-DLBCL cell line OCI-Ly10[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: 6- to 8-week-old female NOD.Cg-Prkdcscid Il2rgtm1Wjl/SzJ (NSG) mice with a murine DLBCL xenogeneic tumor model[1]
Dosage: 400 μg per animal (25 g), corresponding to approximately 16 mg/kg.
Administration: Intraperitoneal administration; started 1 or 12 days after transplantation and given continuously every 24 hr; daily application
Result: Daily administration strongly impaired the expansion of the ABC-DLBCL cell line OCI-Ly10.

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 (16.11 mM); Clear solution

    This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).

    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 (16.11 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.
