Abstract
Use of hypoxia-activated prodrugs has emerged as a strategy for selectively targeting tumors in hypoxic conditions harboring reductive environments. In this issue of Cell Chemical Biology, Skwarska etal. (2021) report a hypoxia-activated prodrug targeting histone deacetylases (lysine deacetylases, KDACs) selectively over normoxic cells with activity in an animal model.
