| Description | Mepazine (Pecazine) is a potent and selective inhibitor of MALT1, inhibiting GSTMALT1 full length and GSTMALT1 325-760 with IC50s of 0.83 μM and 0.42 μM, respectively. Mepazine enhances apoptosis and impacts cell viability. |
| In vitro | Mepazine (5, 10, and 20 μM) decreases cell viability in the ABC-DLBCL cells HBL1, OCI-Ly3, U2932, and TMD8, without significantly affecting GCB-DLBCL cells[1]. |
| In vivo | In female NSG mice with a murine DLBCL xenogeneic tumor model, Mepazine (16 mg/kg; i.p.) interferes with the growth and induces apoptosis of ABC-DLBCL cell line OCI-Ly10. Mepazine strongly impairs the expansion of OCI-Ly10 with daily administration[1]. |

DMSO
| |||||||||||||||||||||||||||||||
Dissolve 2 mg of the compound in 100 μL DMSO
to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO
stock solution to 400 μL PEG300
and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O
and mix thoroughly until a homogeneous solution is obtained.
