生物活性

PROTAC BET Degrader-15 is a BET PROTAC degrader with DC50 values of <0.10 nM, <0.01 nM, and <0.01 nM against BRD2, BRD3, and BRD4, respectively. PROTAC BET Degrader-15 induces significant G2/M phase cell cycle arrest and triggers apoptosis. PROTAC BET Degrader-15 causes marked downregulation of c-Myc, accompanied by upregulation of the cell cycle inhibitory protein p21, downregulation of CDK6, and an increase in the apoptosis marker cleaved PARP. PROTAC BET Degrader-15 is applicable to the research of hematologic malignancies and lung cancer[1].

Western Blot Analysis[1]

Cell Line: MV4-11 and A549 cells
Concentration: 5 nM (MV4-11 cells, 2 h); 20 nM (A549 cells, 2 h); 10 μM MG132, 10 μM Pomalidomide, 10 μM MLN4924, 100 nM compound 10 (2 h pretreatment)
Incubation Time: 2 h (PROTAC BET Degrader-15 treatment); 2 h (pretreatment prior to PROTAC BET Degrader-15 addition)
Result: Had induced degradation of BRD2, BRD3, and BRD4 completely abolished by pretreatment with MG132, Pomalidomide, MLN4924, or compound 10 in both MV4-11 and A549 cells.

Cell Cycle Analysis[1]

Cell Line: MV4-11 cells
Concentration: 1, 5, 20 and 50 nM
Incubation Time: 24 h
Result: Induced a significant, dose-dependent arrest at the G2/M phase of the cell cycle.

Apoptosis Analysis[1]

Cell Line: MV4-11 cells
Concentration: 1, 5 and 20 nM
Incubation Time: 24 h
Result: Elicited pronounced pro-apoptotic effects starting at 1 nM, with apoptosis increasing in a dose-dependent manner.

Western Blot Analysis[1]

Cell Line: MV4-11, A549, and MDA-MB-231 cells
Concentration: 3.3, 10, 100, 200 and 1000 nM
Incubation Time: 24 h
Result: Caused dose-dependent downregulation of C-Myc and CDK6, upregulation of P21, and an increase in cleaved-PARP levels (with a corresponding decrease in full-length PARP) in all three cell lines.

Cell Migration Assay [1]

Cell Line: MDA-MB-231 breast cancer cells
Concentration: 50 and 100 nM
Incubation Time: 0, 6, 12 h post-treatment monitoring
Result: Significantly suppressed cell migration relative to controls, as measured by reduced wound closure over time.

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.
