Ferroptosis-IN-3（Compound 25）是一款抑制RSL3引起的铁死亡（HT-1080细胞中EC50为8.6nM）的铁死亡抑制剂。此外，Ferroptosis-IN-3能有效清除DPPH和ABTS自由基（EC50分别为3.94μM与6.3μM），并且能降低脂质过氧化水平。

Erastin2 是一种铁死亡诱导剂，通过与亲脂性自由基捕获抗氧化剂ferrostatin-1或铁螯合剂去铁胺（DFO）来诱导细胞死亡。

viFSP1为跨物种的FSP1抑制剂，能诱发FSP1依赖的细胞铁死亡(ferroptosis)。该化合物通过靶向FSP1上的高度保守的NAD(P)H结合口袋，直接作用于FSP1，从而抑制其活性。此外，viFSP1还能促进脂质过氧化，显示出潜在的抗癌效果。

6(5H)-Phenanthridinone is an inhibitor of poly(ADP-ribose) polymerase 1 (PARP1) and PARP2. It decreases radiation-induced PARP activity and proliferation of RDM4 murine lymphoma cells. 6(5H)-Phenanthridinone reduces NF-κB-induced transcription of the genes encoding TNF-α, IL-2, and IFN-γ in rat lymphocytes. In vivo, 6(5H)-phenanthridinone reduces spinal cord expression of inducible nitric oxide synthase (iNOS), IL-1β, TNF-α, IL-2, and IFN-γ and reduces disease score in a rat model of experimental autoimmune encephalomyelitis (EAE). It also decreases serum levels of lactate dehydrogenase as well as hepatic lipid peroxidation, oxidative DNA damage, and PARP levels.

NYY-6a 是一种针对铁死亡 (Ferroptosis) 的抑制剂。在 786-O 和 HT-1080 细胞中，NYY-6a 对 RSL3 诱导的铁死亡展现出明显的抑制作用，EC50值分别为 52 nM 和 50 nM。作为自由基捕获抗氧化剂 (RTA)，NYY-6a 在减少脂质过氧化方面的功效可与 ferrostatin-1 和 liproxstatin-1 相媲美。NYY-6a 可用于铁死亡相关的病理研究。

9c(i472) is an inhibitor of 15-lipoxygenase-1 (15-LO-1; IC50 = 0.19 μM).1 It decreases LPS- and IFN-γ-induced NF- B activity in RAW-Blue cells when used at concentrations of 0.2, 1, and 5 μM. 9c(i472) reduces LPS- and IFN-γ-induced increases in Nos2 expression and lipid peroxidation in RAW 264.7 cells when used at a concentration of 5 μM.
