R4VPL3-1
R4VPL3-1 is a selective GPX4 inhibitor and ferroptosis inducer. R4VPL3-1 also acts as a molecular glue that simultaneously targets RNF4 and VHL; it binds to and modifies GPX4 to inhibit its anti-ferroptotic function. R4VPL3-1 induces iron-dependent lipid peroxidation and ferroptosis-mediated rapid cell death in cancer cells. R4VPL3-1 can be used in research on plx4032-resistant human melanoma, human cutaneous squamous cell carcinoma, metastatic human sarcoma, malignant peripheral nerve sheath tumor, pigmented villonodular synovitis, undifferentiated pleomorphic sarcoma, myxofibrosarcoma, and lung adenocarcinoma.

R4VPL3-1 (5-10 μM; 2-6 h) induces dose- and time-dependent degradation of RNF4, its stabilized phosphorylated oncoprotein substrates (p-c-Myc, p-β-catenin), and VHL in PLX4032-resistant A375R human melanoma cells[1].
R4VPL3-1 (0.1-3 μM; 3-8 days) selectively inhibits proliferation and sphere formation of cancer cells (A375R, SCC1, 143B) but not non-tumorigenic HaCaT cells or primary MEFs, with IC50 values of ~0.3 μM for SCC1 cells and ~1.2 μM for A375R cells[1].
R4VPL3-1 (1-10 μM; 2-6 h) induces time- and dose-dependent cell death in PLX4032-resistant A375R human melanoma cells, with >50% cell death observed at 3 μM after 6 h or at 10 μM after 4 h[1].
R4VPL3-1 (3 μM; 2-2.5 h) induces lipid peroxidation in PLX4032-resistant A375R human melanoma cells, a hallmark of ferroptosis, and this effect is blocked by the ferroptosis inhibitor Ferr-1 (HY-100579)[1].
R4VPL3-1 (3 μM; 72 h) selectively inhibits proliferation of BEAS-2B cells transformed with EGFR pathway oncogenes (BRAFV600E, EGFR L858R) but not with a PI3K pathway oncogene (PIK3CA H1047R)[1].
R4VPL3-1 (0.1-5 μM; 3-8 days) inhibits proliferation and sphere formation of multiple primary patient-derived sarcoma and lung adenocarcinoma cells, with IC50 values ranging from 0.3 μM to 1 μM[1].

Cell Line:HEK293 cells overexpressing HA-tagged wild-type RNF4 or HA-tagged RNF4 double mutant (HA-RNF4DM, Cys51A/Cys91A)
-
Concentration:3 µM (Biotin-R4VPL3-1 binding)
-
Incubation Time:48 h (post-transfection); 2 h (α-HA beads incubation); 1 h (Biotin-R4VPL3-1 binding at 4°C)
-
Result:Bound to HA-RNF4, as detected by α-biotin Western blot.
Did not bind to HA-RNF4DM, which harbors mutations at Cys51 and Cys91.

Cell Line:PLX4032-resistant A375R human melanoma cells
-
Concentration:5-10 μM (dose-dependent treatment for RNF4, p-c-Myc, p-β-catenin; dose-dependent treatment for VHL); 10 μM (time-dependent treatment for RNF4, p-c-Myc, p-β-catenin; time-dependent treatment for VHL)
-
Incubation Time:2-6 h (time-dependent treatment for RNF4, p-c-Myc, p-β-catenin); 2-4 h (time-dependent treatment for VHL)
-
Result:Caused a dose-dependent reduction in RNF4, p-c-Myc, and p-β-catenin protein levels, with 10 μM reducing RNF4 to ~15%, p-c-Myc to ~10%, and p-β-catenin to ~10% of control levels.
Reduced RNF4 to ~65% at 2 h, ~40% at 4 h, and ~30% at 6 h of control levels via time-dependent treatment with 10 μM.
Caused a dose-dependent reduction in VHL protein levels, with 5 μM and 10 μM reducing VHL to ~30% of control levels.
Reduced VHL to ~60% at 2 h and ~30% at 4 h of control levels via time-dependent treatment with 10 μM.
