MS41

MS41 is a selective eleven-nineteen leukemia (ENL) PROTAC degrader, with DC50s of 3.50 nM (MV4;11), 2.84 nM (SEMK2), 3.03 nM (Jurkat), and 26.58 nM (KASUMI1), respectively. MS41 effectively inhibits the growth of ENL-dependent leukemia cells, induces G1 cell cycle arrest and increases apoptosis. MS41 reduces the chromatin occupancy of ENL-associated transcription elongation machinery, and suppresses oncogenic gene expression and leukemia progression. Red: ENL ligand (HY-169094). Black: linker (HY-W105744). Blue: VHL ligand (HY-112078)[1].
