KAT2A degrader-2
KAT2A degrader-2 is a selective molecular glue degrader targeting KAT2A, with a DC50 of 22 nM in Kelly cells. KAT2A degrader-2 acts as a molecular glue to recruit KAT2A to CRBN, forming a ternary complex that drives the polyubiquitination and proteasome-dependent degradation of KAT2A. KAT2A degrader-2 reduces the acetylation level of histone H3 lysine 9 via the ubiquitin-like and proteasome-dependent pathway. KAT2A degrader-2 can be used for the research of acute myeloid leukemia.

Biologische Aktivität
|
KAT2A 22 nM (DC50) |
KAT2A degrader-2 (compound 4) potently and selectively mediates dimerization between CRBN and KAT2ANTD via a degron-independent interface involving KAT2A residue Y200, with a measured IC50 of 0.07 μM for wild-type KAT2ANTD displacement[1].
KAT2A degrader-2 (6 h) potently degrades endogenous KAT2A in Kelly cells with a DC50 of 22 nM and 90% maximum degradation after 6-hour treatment[1].
KAT2A degrader-2 (0.1-1 μM; 6 h) selectively degrades KAT2A over KAT2B, GSPT1, and GSPT2 in Kelly cells, functionally reducing H3K9Ac levels in a CRBN- and proteasome-dependent manner after 6-hour treatment[1].
KAT2A degrader-2 (1 μM; 6 h) exhibits exquisite proteome-wide selectivity, degrading only KAT2A in Kelly cells after 6-hour treatment with 1 μM[1].
KAT2A degrader-2 selectively recruits KAT2A to CRBN in Kelly cell lysates, with no other off-target proteins showing significant enrichment[1].
KAT2A degrader-2 (0.1-1 μM; 6 h) functionally inhibits KAT2A activity, reducing H3K9Ac levels in a CRBN- and proteasome-dependent manner in EOL-1 and MV4;11 AML cells after 6-hour treatment[1].
KAT2A degrader-2 (1 μM; 6 h) maintains exquisite proteome-wide selectivity, degrading only KAT2A in EOL-1 and MV4;11 AML cells after 6-hour treatment with 1 μM[1].
KAT2A degrader-2 (10-10-10-5 M; 9 days) exhibits context-specific antiproliferative activity in AML cell lines, with IC50 values ranging from 32.7 nM to 70.1 nM in KMT2A-rearranged sensitive lines and >10,000 nM in insensitive lines after 9-day treatment[1].

Cell Line:Kelly neuroblastoma cells
-
Concentration:0.1-1 μM; 0.25 μM (combined with 1 μM MLN4924 or bortezomib)
-
Incubation Time:6 h; 6 h (after MLN4924 or bortezomib pretreatment)
-
Result:Induced dose-dependent degradation of KAT2A, with negligible degradation of the homologous KAT2B at doses >250 nM, and no degradation of GSPT1 or GSPT2 up to 1 μM.
Caused dose-dependent reduction of histone H3 lysine 9 acetylation (H3K9Ac), a primary KAT2A substrate.
Had its induced KAT2A degradation and H3K9Ac reduction blocked by pretreatment with the neddylation inhibitor MLN4924 or proteasome inhibitor bortezomib.

-
Concentration:10-10-10-5 M
-
Incubation Time:9 days (with retreatment as needed)
-
Result:Induced antiproliferative activity with IC50 = 32.7 nM in MV4;11 cells, IC50 = 40.6 nM in EOL-1 cells, IC50 = 37.3 nM in MOLM13 cells, and IC50 = 70.1 nM in MONOMAC6 cells.
Caused minimal sensitivity in NB-4, NOMO1, and THP-1 cells, with IC50 values >10,000 nM.

Concentration:0.1-1 μM; 0.25 μM (combined with 1 μM MLN4924 or bortezomib)
-
Incubation Time:6 h; 6 h (after MLN4924 or bortezomib pretreatment)
-
Result:Induced dose-dependent reduction of H3K9Ac in both EOL-1 and MV4;11 cells.
Had its induced H3K9Ac reduction blocked by pretreatment with MLN4924 or bortezomib, confirming dependence on neddylation and proteasome function.
