      Description
      OverviewA cell-permeable phenothiazine that that inhibits MALT1, but not caspase-3 or -8, proteolytic activity (IC50 = 0.83 and 0.42 µM, respectively, against full-length or paracaspase domain-catalyzed Ac-LRSR-AMC hydrolysis) in a reversible and noncompetitive manner. Shown to suppress ABC-DLBCL constitutive cellular MALT1 activity (by >75% at 10 µM; IC50 <5 µM in U2932, OCI-Ly10, OCI-Ly3, HBL1, and TMD8 cultures) and RelB cleavage, resulting in ABC-DLBCL-selective cytotoxicity (≥27% cell death in 4 days at 10 µM) over GCB-DLBCL (≤26% cell death in 4 days at 20 µM) both in cultures in vitro and in mice (400 µg/kg daily i.p.) in vivo.

      Please note that the molecular weight for this compound is batch-specific due to variable water content. Please refer to the vial label or the certificate of analysis for the batch-specific molecular weight. The molecular weight provided represents the baseline molecular weight without water. In addition, the CAS number provided represents variable hydrochloride content; the parent compound CAS number is 60-89-9 and the monohydrochloride CAS number is 2975-36-2.

      DescriptionA cell-permeable phenothiazine that inhibits MALT1, but not caspase-3 or -8, proteolytic activity (IC50 = 0.83 and 0.42 µM, respectively, against full-length or paracaspase domain-containing aa 325-760 MALT1 GST fusion-catalyzed Ac-LRSR-AMC hydrolysis) in a reversible and noncompetitive manner and blocks anti-CD3/CD28-stimulated IL-6 production (20 h) in primary murine CD4+ T-cell (by 77%) and human PBMC cultures (by 51 - 89%). Shown to suppress ABC-DLBCL constitutive cellular MALT1 activity (>75% suppression by 10 µM Mepazine; IC50 <5 µM in U2932, OCI-Ly10, OCI-Ly3, HBL1, and TMD8 cultures) and RelB cleavage, resulting in effective blockage of NF-κB-dependent IL-6, IL-10, as well as anti-apoptotic Bcl-xL and FLIP-L expressions. Mepazine exhibits ABC-DLBCL-selective cytotoxicity (≥27% cell death in 4 days by 10 µM Mepazine in HBL-1, OCI-Ly3, OCI-Ly10, TMD8, and U2932 cultures) over GCB-DLBCL (≤26% cell death in 4 days by 20 µM Mepazine in DJAB, Su-DHL-4, and Su-DHL-6 cultures) both in cultures in vitro and in mice (74%, and 0% suppression, respectively, of OCI-Ly10 and Su-DHL-6 tumor expansion on day 22 post cancer transplant; via daily 400 µg/kg i.p.) in vivo.

      Please note that the molecular weight for this compound is batch-specific due to variable water content. Please refer to the vial label or the certificate of analysis for the batch-specific molecular weight. The molecular weight provided represents the baseline molecular weight without water. In addition, the CAS number provided represents variable hydrochloride content; the parent compound CAS number is 60-89-9 and the monohydrochloride CAS number is 2975-36-2.
