NU223612
Based on 1 Customer Validation
NU223612 is a cereblon (CRBN)-recruiting IDO1 PROTAC degrader, with a DC50 value of 0.329-0.5438 μM against human IDO1, and it is capable of penetrating the blood-brain barrier. NU223612 directly binds to IDO1, mediates the degradation of both wild-type and catalytically inactive mutant IDO1 proteins, and does not degrade TDO2. NU223612 inhibits IDO1-mediated enzymatic activity. NU223612 directly binds to CRBN and promotes the formation of a cooperative ternary complex with IDO1. NU223612 induces ubiquitin-dependent proteasomal degradation of the IDO1 protein. NU223612 suppresses IDO1-mediated non-enzymatic phosphorylation of NF-κB p65 and the DNA-binding activity of downstream transcription factors. NU223612 can be used in studies of glioblastoma (malignant glioma).

In Vitro
NU223612 (0.01-30 μM; 24 h) potently degrades IDO1 protein with a DC50 of 0.3290 μM in interferon-gamma stimulated U87 human glioblastoma cells[1].
NU223612 (0.01-30 μM; 24 h) potently degrades IDO1 protein with a DC50 of 0.5438 μM in interferon-gamma stimulated GBM43 human glioblastoma cells[1].
NU223612 (1-10 μM; 1-96 h) mediates sustained, long-lasting IDO1 protein degradation in GBM43 cells, and the degradation effect in U87 cells does not require continuous compound presence in culture media in U87 and GBM43 human glioblastoma cells[1].
NU223612 (80 μM stock) directly binds both its target IDO1 protein and the cereblon E3 ubiquitin ligase protein with nanomolar affinity[1].
NU223612 (1.4 μM; 15 min pre-incubation) drives the formation of a highly stable, positively cooperative ternary complex between the IDO1 protein and the CRBN E3 ligase protein[1].
NU223612 (0.1-30 μM; 24 h) is a broadly active, IDO1-selective degrader that acts across multiple IDO1-expressing human and murine cell types, targets IDO1 in both major subcellular compartments, and degrades both wild-type and catalytically inactive IDO1 protein[1].
NU223612 (1-10 μM; 24 h) directly promotes the monoubiquitination of IDO1 protein, a required upstream step of targeted proteasomal degradation[1].
NU223612 (1-10 μM; 24 h) degrades IDO1 protein exclusively via the canonical cereblon-dependent, ubiquitin-mediated proteasomal degradation pathway[1].
NU223612 (0.1-30 μM; 24 h) inhibits both the canonical enzymatic tryptophan metabolic function and the non-enzymatic NF-κB-mediated immunosuppressive function of IDO1 in human GBM cells[1].

Cell Line:Interferon-gamma stimulated U87 human glioblastoma cells
-
Concentration:0.01-30 μM (24 h incubation); 10 μM (24 h initial library screening)
-
Incubation Time:24 h
-
Result:Degrades IDO1 protein in a dose-dependent manner, achieving 94% IDO1 degradation at 10 μM, and exhibits measurable IDO1 protein degradation activity at 100 nM.
The half-maximal IDO1 degradation concentration (DC50) in U87 cells is 0.3290 μM.
-
Cell Line:Interferon-gamma stimulated GBM43 human glioblastoma cells
-
Concentration:0.01-30 μM
-
Incubation Time:24 h
-
Result:Degrades IDO1 protein in a dose-dependent manner, with a measured half-maximal IDO1 degradation concentration (DC50) of 0.5438 μM.
-
Cell Line:U87 and GBM43 human glioblastoma cells
-
Concentration:10 μM (1-96 h time-course); 1-10 μM (24-72 h continuous treatment in U87 cells)
-
Incubation Time:1-96 h (time-course); 24-72 h (continuous treatment)
-
Result:Initiates IDO1 protein degradation at 16 h post-treatment in U87 cells.
The degradation effect in GBM43 cells persists for at least 96 h.
Continuous treatment with 1 or 10 μM maintains suppressed IDO1 protein levels for up to 72 h in U87 cells.
Even after complete withdrawal from culture media following 24 h of treatment, the IDO1 degradation effect remains intact for at least an additional 48 h.
-
Cell Line:Multiple human cancer cell lines, murine GL261 IDO1-expressing glioma cells, and human PBMCs
-
Concentration:0.1-30 μM
-
Incubation Time:24 h
-
Result:Dose-dependently degrades IDO1 protein in every tested human cancer cell line, human DIPG cell line, GL261 murine glioma cell line, and human PBMC sample.
Equally degrades IDO1 protein in both the cytoplasmic and nuclear subcellular compartments of treated GBM cells, and degrades both wild-type IDO1 and catalytically inactive enzyme-dead mutant IDO1 protein.
Does not reduce TDO2 protein levels, confirming it is specifically selective for IDO1.
-
Cell Line:FLAG-tagged IDO1 expressing U87 cells
-
Concentration:1-10 μM (NU223612); 10 μM (cereblon E3 ligase modulator compound 1); 0.5 μM (MLN4924); 5 μM (MG132); 10 μM (NU223618); 250 nM (BGB-7204)
-
Incubation Time:24 h
-
Result:Co-treatment with excess cereblon E3 ligase modulator compound 1 (to compete for CRBN binding), the E1 ligase inhibitor MLN4924, or the proteasome inhibitor MG132 completely ablates NU223612-mediated IDO1 degradation.
A competitive IDO1 inhibitor co-treatment blocks NU223612 activity, while a non-competitive IDO1 inhibitor co-treatment does not prevent NU223612-mediated IDO1 degradation.
