GPX4-IN-24
GPX4-IN-24 is an orally active glutathione peroxidase 4 (GPX4) inhibitor with a human IC50 of 10.90 μM, human Kd of 10.04 μM. GPX4-IN-24 suppresses GPX4 enzymatic activity, disrupts redox homeostasis, drives lipid peroxidation, promotes lipid peroxidation, and induces ferroptosis. GPX4-IN-24 can be used for the research of triple-negative breast cancer.

GPX4 10.90 μM (IC50) |
GPX4 10.04 μM (Kd) |
GPX4-IN-24 (DA-5) binds directly to recombinant human GPX4 with a dissociation constant (Kd) of 10.04 μM[1].
GPX4-IN-24 (2.63-30 μM; 15 min) potently inhibits recombinant human GPX4 enzymatic activity with an IC50 of 10.90 μM[1].
GPX4-IN-24 (5 μM; 1 h) significantly inhibits GPX4 enzymatic activity in MDA-MB-231 triple-negative breast cancer cell lysates[1].
GPX4-IN-24 (1.25-20 μM; 72 h) selectively inhibits the proliferation of MDA-MB-231, MDA-MB-468, BT-549, and 4T1 TNBC cells while sparing SK-BR-3 non-TNBC cells and MCF10A normal mammary epithelial cells[1].
GPX4-IN-24 (2.5 μM; 7 days) suppresses colony formation in MDA-MB-231 and MDA-MB-468 TNBC cells but not in MCF10A normal mammary epithelial cells after 7-10 days of treatment[1].
GPX4-IN-24 (5 μM; 24 h) induces selective cell death in MDA-MB-231 TNBC cells while sparing MCF10A normal mammary epithelial cells[1].
GPX4-IN-24 (10 μM; 48 h) induces time-dependent lipid ROS accumulation in MDA-MB-231 TNBC cells, which is attenuated by ferroptosis inhibitors Ferrostatin-1 (HY-100579) and Liproxstatin-1 (HY-12726), while having no significant effect on lipid ROS levels in MCF10A normal mammary epithelial cells[1].
GPX4-IN-24 (5 μM; 24 h) alters the lipid profile of MDA-MB-231 TNBC cells, significantly upregulating ferroptosis-associated lipids including phosphatidic acid, phosphatidylethanolamine, phosphatidylinositol, and lysophospholipids[1].
GPX4-IN-24 (2.5-10 μM; 24 h) upregulates transferrin receptor 1 (TfR1) expression in MDA-MB-231 TNBC cells[1].
