JKE-1674
Based on 6 publication(s) in Google Scholar
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.

JKE-1674 exhibits activity indistinguishable from that of ML210 in cellular target engagement assays including yielding the same +434Da GPX4 adduct in cells. JKE-1674 kills LOX-IMVI cells in a manner that is equipotent to ML210 and is completely rescued by ferroptosis inhibitors. JKE-1674 forms a nitrile-oxide electrophile in cells. JKE-1674 dehydration yields a nitrile-oxide electrophile that binds GPX4. JKE-1674 exhibits far greater stability than chloroacetamide inhibitors[1].
