JKE-1674 is an orally active glutathione peroxidase 4 (GPX4) inhibitor and an active metabolite of GPX4 inhibitor ML-210. JKE-1674, an analog of ML-210 in which the nitroisoxazole ring is replaced with an α-nitroketoxime. JKE-1674 can convert into a nitrile oxide JKE-1777. JKE-1674 kills LOX-IMVI cells in a manner that is equipotent to ML-210 and is completely rescued by ferroptosis inhibitors[1][2][3].

JKE-1674 is an inhibitor of glutathione peroxidase 4 (GPX4) and an active metabolite of the GPX4 inhibitor ML-210 .1 JKE-1674 reduces viability of LOX-IMVI cancer cells (EC50 = 0.03 μM) and in a panel of additional cancer cell lines, an effect that can be blocked by the ferroptosis inhibitor ferrostatin-1 .
