  3. PROTAC IKKβ/NR4A1 degrader-1

PROTAC IKKβ/NR4A1 degrader-1 is a highly efficient and effective dual-PROTAC degrader targeting IKKβ and NR4A1. PROTAC IKKβ/NR4A1 degrader-1 can increase the levels of caspase 3 and cleaved caspase 3 proteins, while the necroptosis marker RIP kinase remained unchanged, indicating that it can induce apoptosis. PROTAC IKKβ/NR4A1 degrader-1 can be used for the study of Acute myeloid leukemia (AML). Red: IKKβ/NR4A1 ligand (HY-13067); Blue: E3 ligase CRBN ligand (HY-14658); Black: Linker (HY-79577).

PROTAC IKKβ/NR4A1 degrader-1 can increase the levels of caspase 3 and cleaved caspase 3 proteins, while the necroptosis marker RIP kinase remained unchanged, indicating that it can induce apoptosis. PROTAC IKKβ/NR4A1 degrader-1 can be used for the study of Acute myeloid leukemia (AML). Red: IKKβ/NR4A1 ligand (HY-13067); Blue: E3 ligase CRBN ligand (HY-14658); Black: Linker (HY-79577)[1].

In Vitro

PROTAC IKKβ/NR4A1 degrader-1 (Compound A9) (48 h) shows strong AML cell killing activity in Monomac-6 (IC50 = 0.32 µM), NB-4 (IC50 = 0.23 µM), U-937 (IC50 = 0.36 µM), Molm-13 (IC50 = 0.23 µM), and HL-60 cells (IC50 = 0.54 µM)[1].
PROTAC IKKβ/NR4A1 degrader-1 (0.5-1 µM) dose-dependently increases the levels of caspase 3 and cleaved caspase 3 proteins in NB-4, Monomac-6, and Molm-13 cells, while the necrosis marker RIP kinase remained unchanged, indicating that it can induce apoptosis[1].
PROTAC IKKβ/NR4A1 degrader-1 (0-1 µM) results in a dose-dependent decrease in IKKβ and NR4A1 protein levels in NB-4, Monomac-6, and Molm-13 cells[1].
PROTAC IKKβ/NR4A1 degrader-1 (0.5 μM, 16 h)-mediated degradation of IKKβ and NR4A1 can be reversed by the proteasome inhibitor MG132 (HY-13259), the E3 ligase competitor Pomalidomide (HY-10984), or the neddylation inhibitor Pevonedistat (MLN4924) (HY-70062) in A375 melanoma cells, while PROTAC IKKβ/NR4A1 degrader-1 NC has no degradation activity[1].
PROTAC IKKβ/NR4A1 degrader-1 (10 μM, 3 h) promotes the formation of a ternary complex in HEK293T cells, evidenced by co-immunoprecipitation of IKKβ with exogenous Flag-CRBN and of CRBN with Flag-NR4A1[1].
PROTAC IKKβ/NR4A1 degrader-1 (0.25-1 μM, 48 h) exhibits reduced efficacy in IKKβ or NR4A1 knockout cells[1].
PROTAC IKKβ/NR4A1 degrader-1 (0.125-0.25 μM, 72 h) results in overlap of the NF-κB signaling pathway in Molm-13 and Monomac-6 cells with the enrichment pathway in AML cells with high NR4A1 expression[1].

In Vivo

PROTAC IKKβ/NR4A1 degrader-1 (Compound A9) (2-4 mg/kg, i.p., once every 3 days) effectively attenuates AML disease progression in mouse models of AML[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: C57BL6/J mice were irradiated with 6.5 Gy X-ray and 24 h later 2x104 GFP-tagged KMT2A::MLLT3 AML cells/mouse were injected intravenously[1].
Dosage: The initial four-dose regimen is 4 mg/kg, with all subsequent doses decreasing to 2 mg/kg
Administration: I.p., once every 3 days
Result: AML cell growth slowed significantly.
Showed a trend of prolonged survival, but compared with the control group, it did not reach statistical significance.
No significant difference in the neutrophil count in their blood.

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.
