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.

In Vitro

PROTAC BET Degrader-15 (Compound CR10) (72 h) potently inhibits the proliferation of MV4-11, Molm-13, and HL-60 acute myeloid leukemia cells, with IC50 values of 1.21, 2.14, and 0.69 nM respectively[1].

PROTAC BET Degrader-15 (5-20 nM; 2 h) induces degradation of BRD2, BRD3, and BRD4 in MV4-11 and A549 cells via a ubiquitin-proteasome system-dependent mechanism that relies on CRBN and BET protein binding[1].
PROTAC BET Degrader-15 (1 h) binds to BRD2, BRD3, and BRD4 bromodomains with nanomolar affinity, with IC50 values ranging from 22 nM (BRD3(1)) to 61 nM (BRD4(2))[1].
PROTAC BET Degrader-15 (1-50 nM; 24 h) dose-dependently arrests MV4-11 cells at the G2/M phase of the cell cycle after 24 h of treatment[1].
PROTAC BET Degrader-15 (1-20 nM; 24 h) dose-dependently induces apoptosis in MV4-11 cells, with significant apoptosis observed at concentrations as low as 1 nM after 24 h of treatment[1].
PROTAC BET Degrader-15 (3.3-1000 nM; 24 h) modulates key proteins involved in proliferation, cell cycle regulation, and apoptosis in MV4-11, A549, and MDA-MB-231 cells, including downregulating C-Myc and CDK6, upregulating P21, and inducing PARP cleavage[1].
PROTAC BET Degrader-15 (4-50 nM; 8 d) potently inhibits the colony-forming ability of A549 and MDA-MB-231 solid tumor cells, with near-complete inhibition observed at 10 nM[1].
PROTAC BET Degrader-15 (50-100 nM; 0-12 h) potently inhibits the migratory capacity of MDA-MB-231 breast cancer cells at concentrations of 50 and 100 nM[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 Line: MDA-MB-231 breast cancer cells
Concentration: 50 and 100 nM
Incubation Time: 0, 6, 12 h post-treatment monitoring

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.
