MS41
Based on 1 Customer Validation
MS41 is a ENL PROTAC degrader with a DC50 of 3.50 nM. MS41 recruits the VHL E3 ubiquitin ligase, triggers ENL degradation via the ubiquitin-proteasome system, and simultaneously induces AF9 degradation. MS41 reduces the chromatin occupancy of ENL-associated transcription elongation complexes, suppresses oncogene expression, and activates differentiation gene expression. MS41 inhibits leukemia cell growth and induces cell cycle arrest and apoptosis. MS41 inhibits leukemia progression in xenograft mouse models. MS41 can be used for research on mixed lineage leukemia-rearranged leukemia and nephroblastoma.

ENL 2.84 nM (DC50) |
MS41 (0.1 nM-54 μM; 1 hour) potently inhibits the ENL YEATS domain-H3K9ac interaction with an IC50 of 119.43 nM, binds comparably to AF9 YEATS domain, and does not bind GAS41 or YEATS2 YEATS domains[1].
MS41 (0.25-256 nM; 24 hours) potently, rapidly, and reversibly degrades ENL in MV4;11 cells via a VHL- and ubiquitin-proteasome system-dependent mechanism, with a DC50 of 3.50 nM and >99% maximal degradation[1].
MS41 (0.25-256 nM; 24 hours) potently and rapidly degrades ENL in SEMK2, Jurkat, and KASUMI1 human leukemia cells, with DC50 values ranging from 2.84 to 26.58 nM and >93% maximal degradation[1].
MS41 is a highly selective ENL degrader in MV4;11 cells, with no detectable off-target protein degradation at the proteome-wide level[1].
MS41 (6 days, 12 days for Jurkat and K-562) potently inhibits proliferation of ENL-dependent human leukemia cell lines (MV4;11, RS4;11, SEMK2, KASUMI1) with GI50 values ranging from 21.28 to 406.46 nM, while having no effect on non-ENL-dependent Jurkat and K-562 cells[1].
MS41 (100 nM; 7-10 days) impairs the clonogenic potential of ENL-dependent human leukemia cell lines MV4;11, SEMK2, and KASUMI1, but not non-ENL-dependent Jurkat cells[1].
MS41 (10-300 nM; 24 h) suppresses ENL-dependent oncogenic gene expression programs in MV4;11 cells, down-regulating key leukemia-associated genes and up-regulating myeloid differentiation markers, with effects matching those of ENL knockout[1].
MS41 (100 nM; 6, 24 hours) reduces chromatin occupancy of ENL and its associated transcription elongation machinery (SEC, DOT1L, elongating Pol II) on target genes, leading to suppressed gene expression in MV4;11 cells[1].
MS41 (1-1000 nM; 24, 72 hours) potently degrades wild-type and YEATS domain mutant ENL proteins and suppresses the aberrant HOXA gene expression induced by mutant ENL in HEK293 cells[1].
MS41 (100 nM; 24-72 hours) induces time-dependent G1 cell cycle arrest and apoptosis in MV4;11 human leukemia cells[1].
