ZX703 (compound 5I) is a GPX4-targeting PROTAC that induces efficient, dose- and time-dependent degradation of GPX4 through both ubiquitin–proteasome and autophagy–lysosome pathways, ZX703 results in reactive oxygen species accumulation, ferroptosis induction, and strong mechanistic relevance for cancer biology and ferroptosis-focused therapeutic research.
