MS2133
MS2133 is a VHL-recruiting DOT1L PROTAC degrader. MS2133 possesses antiproliferative activity with a human DOT1L IC50 of 4.6 nM, forms a ternary complex with DOT1L and VHL E3 ligase to drive DOT1L ubiquitination and subsequent proteasomal degradation without affecting DOT1L mRNA transcription, inhibits the proliferation of mixed lineage leukemia-rearranged leukemia cells and downregulates H3K79Me2, restrains proliferation of both tumor and normal cells but lacks cytotoxicity against normal cells, and can be used for the research of mixed lineage leukemia-rearranged leukemia.

Biological Activity
|
DOT1L 4.6 nM (IC50) |
MS2133 (compound 13) (0.3-3 μM; 24 h) potently reduces DOT1L protein levels in THP-1 MLL-r leukemia cells, achieving 70% degradation at 0.3 μM and 77% degradation at 3 μM after 24 h treatment[1].
MS2133 (0.5nM-3.3 μM; 24 h) induces potent concentration-dependent DOT1L degradation in THP-1 cells (DC50 = 56 nM, Dmax = 69%) after 24 h treatment[1].
MS2133 (0.2 nM-3.0 μM; 24 h) induces potent concentration-dependent DOT1L degradation in MV4-11 cells (DC50 = 25 nM, Dmax = 93%) after 24 h treatment[1].
MS2133 (3 μM; 1-48 h) induces time-dependent DOT1L degradation in THP-1 (maximal at 24 h) and MV4-11 (near-complete at 48 h) MLL-r leukemia cells, with downstream H3K79Me2 reduction delayed relative to DOT1L degradation in both cell lines[1].
MS2133 (3 μM; 4-8 h) -induced DOT1L degradation in THP-1 MLL-r leukemia cells occurs via the ubiquitin-proteasome system, as pre-treatment with proteasome inhibitor or NEDD8-activating enzyme inhibitor blocks degradation[1].
MS2133 (3 μM; 24 h) -induced DOT1L degradation in THP-1 MLL-r leukemia cells is VHL-dependent, as co-treatment with a competing VHL ligand blocks degradation[1].
MS2133 (3 μM; 24 h) does not affect DOT1L mRNA expression in MV4-11 and MOLM-13 MLL-r leukemia cells after 24 h treatment at 3 μM[1].
MS2133 (0.3-3 μM; 24 h) -induced DOT1L degradation in THP-1 MLL-r leukemia cells requires DOT1L binding[1].
MS2133 (0.004-3.3 μM) potently inhibits DOT1L methyltransferase activity, achieving >95% inhibition at 4.6 nM[1].
MS2133 (10 μM) is highly selective for DOT1L, showing no significant inhibition of 12 other tested DNA and protein methyltransferases at 10 μM[1].
DOT1L degrader (0.3-3 µM; 24 h) induces dose-dependent degradation of DOT1L protein in MOLM-13 cells after 24-hour treatment at 0.3 µM and 3 µM[1].
MS2133 (3 µM; 24 h) at 3 µM for 24 hours does not significantly alter DOT1L mRNA levels in MOLM-13 cells[1].
DOT1L degrader (0.3-3 µM; 24 h) induces dose-dependent degradation of DOT1L and reduction of H3K79Me2 in MCF10A cells[1].
MS2133 (0.23-30.0 µM; 7 days) exhibits minimal antiproliferative activity in MCF10A cells[1].
DOT1L degrader MS2133 (0.3-3 µM; 24 h) induces dose-dependent degradation of DOT1L (without altering H3K79Me2 levels) in PNT2 cells[1].
MS2133 (0.12-30.0 µM; 7 days) exhibits minimal antiproliferative activity in PNT2 cells[1].
MS2133 (30 nM-15 μM; 7 days) potently inhibits growth of DOT1L-dependent MV4-11 (GI50 = 212 nM) and MOLM-13 MLL-r leukemia cells after 7 days of treatment, while showing no toxicity to THP-1 cells or normal MCF10A and PNT2 cells[1].
MS2133 (0.06-15.0 µM; 7 days) exhibits dose-dependent antiproliferative activity in MOLM-13 cells[1].
MS2133 (0.01-30.0 µM; 7 days) exhibits dose-dependent antiproliferative activity in THP-1 cells over a 7-day treatment period at concentrations ranging from 0.01 µM to 30.0 µM[1].
