Mepazine hydrochloride (Pecazine hydrochloride) 是一种有效的选择性MALT1蛋白酶抑制剂。Mepazine hydrochloride 抑制全长 GSTMALT1 和 GSTMALT1 325-760 段的IC50分别为 0.83 和 0.42 μM。Mepazine hydrochloride 通过增强细胞凋亡 (apoptosis) 来影响 ABC-DLBCL 细胞的生存能力。
| 生物活性 | Mepazine hydrochloride (Pecazine hydrochloride) is a potent and selectiveMALT1protease inhibitor withIC50s of 0.83 and 0.42 μM for GSTMALT1 full length and GSTMALT1 325-760, respectively. Mepazine hydrochloride affects viability of ABC-DLBCL cells by enhancingapoptosis[1]. |

体外研究
(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. |

体内研究
(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].
| Animal Model: | 6- to 8-week-old female NOD.Cg-PrkdcscidIl2rgtm1Wjl/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. |
