MS41

MS41 is a highly potent and selective PROTAC degrader of eleven-nineteen leukemia (ENL) that recruits the von Hippel–Lindau (VHL) E3 ubiquitin ligase, with DC50 values of 3.50 nM (MV4;11), 2.84 nM (SEMK2), 3.03 nM (Jurkat), and 26.58 nM (KASUMI1) . It suppresses oncogenic gene expression, inhibits leukemia cell proliferation, and reduces MLL-r leukemia progression in a xenograft mouse model.
