GPX4-AUTAC
GPX4-AUTAC is a GPX4-targeting autophagy-mediated degrader (AUTAC). GPX4-AUTAC consists of an inhibitor ML162-yne (HY-153748), a degradation tag FBnG (HY-W073762) and a glycol linker (HY-W021401). GPX4-AUTAC promotes the ubiquitination of GPX4 by E3 ligase TRAF6, and enhances the binding with GPX4 and p62, leading to the selective autophagy-dependent degradation of GPX4. GPX4-AUTAC significantly induces ferroptosis and shows a potent anti-cancer activity in breast cancer cells, breast cancer-derived organoids (PDOs) and MDA-MB-231 tumor xenograft mice model, with potent synergistic effects when combined with Sulfasalazine (SAS) (HY-14655) or chemotherapy drugs (Paclitaxel (HY-B0015) or Cisplatin (HY-17394)).

GPX4 |
GPX4-AUTAC (5-80 μM, 12-72 h) significantly reduces the protein level of GPX4 in a dose- and time-dependent manner, but barely affects the mRNA level of GPX4 in MDA-MB-231 and MCF-7 cells [1].
GPX4-AUTAC (20-40 μM, 24 h) effectively reduces the protein level of GPX4 in ovarian cancer, lung cancer, melanoma, and glioma cells[1].
GPX4-AUTAC (10 μM, 24-96 h, 37-57°C) continuously down-regulates GPX4 protein level for 96 h and significantly enhances the thermal stability of GPX4 in heat-denatured intact cells and cell lysates in MDA-MB-231 and MCF-7 cells[1].
GPX4-AUTAC (5-80 μM, 24 h) selectively degrades GPX4 without influence other selenoproteins expression, such as of GPX1, TXNRD1 (GPX4 homologs) or HK2 (a TRAF6/p62 substrate)[1].
GPX4-AUTAC selectively degrades GPX4 and induces ferroptosis in tumor cells (MDA-MB-231 cells) with minimal effect on normal cells (MCF-10A cells)[1].
GPX4-AUTAC (10 μM, 24 h) autophagy-dependently accelerates GPX4 degradation, increases polyubiquitylation of GPX4, specifically the endogenous and exogenous K63-linked ubiquitin chains in HEK293T cells[1].
GPX4-AUTAC (10-40 μM, 12 h) is reversed by PYR-41, NH4Cl and 3-MA to reduce the down-regulation of GPX4 in MDA-MB-231 cells[1].
GPX4-AUTAC (24 h) induces co-localization of GPX4 and p62 and increases co-localization of GPX4 with LC3B or LAMP2 in PDOs[1].
GPX4-AUTAC (40?μM, 24?h) selectively targets GPX4 and ferroptosis is significantly enriched in MDA-MB-231 cells[1].
GPX4-AUTAC (5-40 μM, 72 h) has a specific ferroptosis inductive effect, and significantly enhanced the lipid ROS and promoted accumulation of Fe2+ in MDA-MB-231 cells, but only fully rescued by the ferroptosis inhibitor Ferrostatin-1 (Fer-1) (HY-100579) in MCF-7 cells[1].
GPX4-AUTAC (5-80 μM) induces ferroptosis with mitochondrial dysfunction (abnormal morphology, dense content and disrupted crista) and significant increase in mRNA levels of PTGS2 in MDA-MB-231[1].
GPX4-AUTAC (5-40 μM, 24-96 h) dose- and time-dependently inhibited cell viability and proliferation, with insensitivity to knock-down of GPX4 in both MDA-MB-231 and MCF-7 cells[1].
GPX4-AUTAC (5-40 μM, 4 days) significantly inhibits the growth of PDOs with reducing diameter and bright-field, and PDOs with high expression of GPX4 increases sensitivity [1].
GPX4-AUTAC (10-20 μM, 4 days) down-regulates GPX4 expression and induces ferroptosis with high level of 4-HNE, and inhibits cancer cell proliferation in PDOs with low level of Ki67[1].
GPX4-AUTAC induces much more ferroptosis and has a stronger anti-cancer effect in combination with Sulfasalazine compared to Sulfasalazine alone treatment in MDA-MB-231 and MCF-7 cells and PDOs [1].
GPX4-AUTAC (10?μM, 72 h or 4 days) sensitizes MDA-MB-231 and HCC1806 cells to chemotherapy and synergistically inhibits cell viability and proliferation and the growth of PDOs in combination with chemotherapy drugs (Paclitaxel or Cisplatin)[1].
