PROteolysis‐Targeting Chimeras (PROTACs) in leukemia: overview and future perspectives

open access: yesMedComm, Volume 5, Issue 6, June 2024.
Antileukemic PROteolysis‐TArgeting Chimeras (PROTACs) induce degradation of leukemia‐associated targets, including resistance‐conferring mutant forms. PROTACs against leukemia have increased dramatically. Most antileukemic PROTACs, through an event‐driven mechanism, degrade the target potently, quickly, selectively, and with a long duration of action ...
