| 产品描述: | Bcl-6 抑制剂;Bcl-6 Inhibitors;;Information79-6 (CID5721353) 79-6 (CID5721353) (BCL6 inhibitor) is a BCL6 inhibitor with Kd value of 138 μM.TargetsBcl-6 138 μM(Kd)In vitroSmall molecular BCL6 inhibitor 79-6 is a cell-permeable oxindole compound that selectively inhibits the transcriptional repression activity of BCL6 but does not affect BCL6 protein levels. 79-6 binds an aromatic pocket situated in the BTB domain lateral groove, induces disruption of BCL6 transcriptional complexes, reactivation of BCL6 target genes and selective killing of BCL6-dependent DLBCL cells. BCL6 can also interact with MTA3 through its RD2 domain and represses the terminal differentiation. It recruits CtBP through its DBD domain and represses its own expression. 79-6 suppresses invasive ability and colony-forming ability in both of MCF-7 and MDA231 cells. The inhibition of BCL6 with 79-6 enhanced the mRNA expression of E-cadherin in both of MCF-7 and MDA231 cells. 79-6 reverses the functions of BCL6 in the positive regulation of EMT, invasion and transcriptional repression of E-cadherin in breast cancer cells.In vivoAdministration of 50 mg/kg/day 79-6 to SCID mice induced a 65-70% reduction in the size of established BCL6-dependent DLBCL xenografts, but had no effect on BCL6-independent DLBCLs. Therapeutic targeting of BCL6 with the small molecule 79-6 is an effective antilymphoma strategy in vivo.Cell Research(from reference)Cell lines:MCF-7 and MDA231 cells Concentrations:200 μM Incubation Time:48 h |

In order to test whether CID5721353 (Compound 79-6) can perform as an anti-lymphoma therapeutic agent in vivo, whether it can penetrate tumors after parenteral administration through a distal site is determined. For this purpose 107OCI-Ly7 cells are injected into the right flank of 10 SCID mice and allowed to form tumors. Once tumors reach ~1.5 grams, animals are injected IP with a single dose of 50 mg/kg of CID5721353 in 10% DMSO or vehicle (10% DMSO) and sacrificed at 0.5, 1, 1.5, 3, 6, 12 and 24 hours after CID5721353 administration. Blood and tumors are harvested. Quantitative HPLC/MS analysis of the serum shows that CID5721353 levels peak (to 55 μg/mL, which is equivalent to a 122 μM concentration) one hour after the IP injection. CID5721353 also reaches its highest peak (24.5 ng/mg) at the 1-hour time point in the tumors, and after a sharp decline in levels, decreases gradually over 24 hours. |
