MS44
MS44 is a potent aurora kinase B (AURKB PROTAC) degrader (DC50 = 103 nM). MS44 effectively degrades AURKB in a time- and ubiquitin-proteasome system (UPS) -dependent manner and is selective for AURKB over AURKA and AURKC. MS44 effectively inhibits the proliferation in multiple cancer cell lines and potently induces G2/M arrest. MS44 can be used for the study of AURKB-dependent tumors (Pink: Target protein ligand ; Blue: E3 ligand (HY-112078) ; Black: Linker; E3 ligand + Linker (HY-132938) ).
