GDCNF-11
GDCNF-11 is a type of HSP90 interaction-mediated protein degradation chimera (HIM-PROTAC) degrader that targets and degrades GPX4, with a DC50 of 0.08 μM. GDCNF-11 mediates the ubiquitination and proteasome-dependent degradation of GPX4 by recruiting GPX4 to form a ternary complex with HSP90, increases intracellular lipid peroxides and ROS, and ultimately triggers Ferroptosis. GDCNF-11 inhibits tumor growth in mouse models, downregulates GPX4 protein in xenograft tumors, and upregulates the lipid peroxidation marker. GDCNF-11 can be used for the research of fibrosarcoma.

GDCNF-11 (0.03-3 μM; 2-24 h, 24 h treatment followed by 0-24 h washout) potently degrades GPX4 in HT-1080 cells with a DC50 of 0.08 μM, following a time-dependent pattern with transient early upregulation and sustained post-washout activity for 12 h[1].
GDCNF-11 (0.1-1 μM; 24 h) does not alter GPX4 mRNA expression in HT-1080 cells, indicating it acts by degrading GPX4 protein rather than modulating transcription[1].
GDCNF-11 binds to recombinant human HSP90α with high affinity, with a Kd value of 0.19 μM; it inhibits the growth of HT-1080 cells, with an IC50 of 0.74 μM; and its cytotoxicity is mainly mediated by ferroptosis[1].
GDCNF-11 (0.3-1 μM; 24 h, 2 h pretreatment) induces proteasome-dependent GPX4 degradation in HT-1080 cells via HSP90 (both α and β isoforms) recruitment, ternary complex formation, and ubiquitination mediated by cullin E3 ligases including CUL5 and CHIP[1].
GDCNF-11 forms a stable ternary complex with HSP90 and GPX4 via conserved ligand-protein interactions and additional inter-protein contacts, supporting its mechanism of action as an HIM-PROTAC[1].
GDCNF-11 (1 μM; 24 h) exhibits high selectivity for GPX4 degradation in HT-1080 cells, with only a small number of additional proteins significantly altered, including upregulated HMOX1[1].
GDCNF-11 (varied; 12 h) dose-dependently increases intracellular lipid peroxidation in HT-1080 cells, an effect that is abrogated by ferroptosis inhibitor Fer-1, consistent with ferroptosis induction[1].
GDCNF-11 (1 μM; 24 h) induces a significant increase in intracellular ROS and Fe2+ levels in HT-1080 cells, consistent with ferroptosis activation[1].
GDCNF-11 (1 μM; 24 h) induces ferroptosis-specific mitochondrial morphological changes and autophagosome-like structures in HT-1080 cells[1].

Concentration:0.03, 0.06, 0.1, 0.3, 0.6, 0.8, 1 μM (dose-dependent assays)
1 μM (time-course and washout assays) -
Incubation Time:24 h (dose-dependent assays)
2, 4, 6, 12, 24 h (time-course and washout assays) -
Result:Reduced GPX4 protein levels in a dose-dependent manner, with a GPX4 degradation DC50 of 0.08 μM after 24 h treatment.
Observed a hook effect, with decreased degradation efficacy at 3 μM.
Began to decrease GPX4 protein levels after 12 h of treatment with 1 μM, reaching near-complete depletion at 24 h; noted a transient upregulation of GPX4 at 4 h post-treatment.
Induced sustained GPX4 degradation for 12 h after washout of 1 μM.

2 h pretreatment -
Result:Had its induced GPX4 degradation completely abrogated by MG132 (HY-13259) pretreatment, confirming proteasome-dependent degradation.
Had its induced GPX4 depletion rescued by pretreatment with ML162 (HY-100002) or BIIB021 (HY-10212), demonstrating binding to GPX4 and HSP90 at their respective ligand sites.
Had its induced GPX4 degradation abrogated by HSP90 siRNA knockdown; selective inhibition of either HSP90α or HSP90β reduced degradation efficacy, with combined inhibition further diminishing activity, showing both isoforms contribute to degradation.
Had its induced GPX4 degradation rescued by MLN4924 (HY-70062) pretreatment, confirming cullin E3 ligase involvement.
Had its induced GPX4 degradation reduced by CUL5 or CHIP siRNA knockdown, indicating these E3 ligases mediate the process.
Increased GPX4 ubiquitination levels and promoted co-immunoprecipitation of HSP90 and GPX4, confirming ternary complex formation and ubiquitination-dependent degradation.

Result:Suppressed HT-1080 xenograft growth dose-dependently with stronger antitumor activity than 25 mg/kg ML162 and 25 mg/kg BIIB021.
Downregulated tumor GPX4 and upregulated 4-hydroxynonenal at 12, 24 and 36 h after single 50 mg/kg or 100 mg/kg injection; 50 mg/kg administration only caused mild weight loss and no pathological injury in major organs verified by H&E staining.
