JKE-1674 是一种具有口服活性的谷胱甘肽过氧化物酶 4 (GPX4) 抑制剂，是 GPX4 抑制剂 ML-210 的活性代谢物。JKE-1674 是 ML-210 的类似物，其中硝基异恶唑环被 α- 硝基酮肟取代。JKE-1674 可以转换成丁腈氧化物 JKE-1777。JKE-1674 以与 ML-210 相同的方式杀死 LOX-IMVI 细胞，并被 ferroptosis 抑制剂完全挽救。

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.

GPX4

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. has not independently confirmed the accuracy of these methods. They are for reference only.

JKE-1674 (50?mg/kg; p.o.) can be detected in the serum of mice dosed orally with the compound. has not independently confirmed the accuracy of these methods. They are for reference only. Animal Model: SCID mice
