EN1033
Based on 1 Customer Validation
EN1033 is a covalent immune regulatory transcription factor 5/8 (IRF5/8) molecular glue degrader. EN1033 degrades IRF5 in a proteasome-dependent manner. EN1033 engages and degrades IRF8 more robustly and rapidly. EN1033 covalently targets C28 and C223 to destabilize and degrade IRF5 and IRF8 respectively, thereby inhibiting their pro-inflammatory transcriptional activity. EN1033 serves as a promising tool for the study of autoimmune and inflammatory disorders.

Biological Activity
EN1033 (6.25-100 μM) does not exhibit cytotoxicity in THP1 macrophage leukemia cancer cells, nor does it induce stress granules formation[1].
EN1033 (1-µM, 24 h) induces on-pathway inhibition of IRF5 transcriptional activity[1].
EN1033 (100 μM, 18 h) degrades IRF8 in THP1 cells, which is proteasome-dependent[1].
EN1033 (12.5-100 μM, 2-24 h) degrades both IRF8 and IRF5, in a dose-responsive and time-dependent manner[1].
EN1033 (100 μM, 6 h) engages IRF8 more robustly than IRF5, while EN1033 and its analog TH3-189 exert only moderate effects across the proteome[1].
EN1033 (50 μM, 18-24 h) causes the degradation of IRF5 and IRF8 by targeting C28 and C223, respectively[1].
EN1033 (12.5-100 μM, 24 h) degrades IRF8 in IRF5 Knockout cells, suggesting IRF5 does not regulate IRF8. In contrast, IRF8 knockdown markedly reduces IRF5 levels, indicating IRF8 regulates IRF5 in THP1 cells[1].

-
Cell Line:THP1 cells
-
Concentration:12.5, 25, 50, 75, 100 μM
-
Incubation Time:24 h
-
Result:Decreased the levels of IRF8 and IRF5 gradually as the concentration increased.
Triggered the most prominent degradation of IRF8 and IRF5 at a concentration of 100 μM.
-
Cell Line:THP1 cells
-
Concentration:100 μM
-
Incubation Time:0, 2, 4, 8, 20, 24 h
-
Result:Induced the degradation of IRF8 and IRF5 starting at 8 h, and this effect was gradually strengthened over time.
-
Cell Line:HEK293T cells
-
Concentration:50 μM
-
Incubation Time:18, 24 h
-
Result:Induced IRF5 degradation, which was fully rescued in C28S and C28S/C121S variants, but not in the C121S mutant.
Triggered IRF8 loss, which was fully rescued in C223S and C223S/C385S IRF8 mutants, but not in the C385S mutant-expressing cells.
