GDCNF-11 is a HIM-PROTAC GPX4 degrader based on the chaperone protein HSP90. GDCNF-11 promotes the ubiquitination and degradation of GPX4 through the HSP 90 chaperone complex, reduces endogenous GPX4 expression to induce ferroptosis in HT-1080 cells, and the DC50 value is 0.08 μM (Pink: Target protein ligand (HY-153748); Blue: HSP90 ligand (HY-10212); Black: Linker (HY-W169526))[1].
