(-)-Bornyl ferulate is a 5-lipoxygenase and COX inhibitor with IC₅₀s of 10.4 μM and 12.0 μM, respectively.

Fenleuton is a 5-lipoxygenase inhibitor. Fenleuton is promising for research of leukotriene-mediated inflammatory diseases.

2'-Hydroxy-3,4-dimethoxychalcone is a chalcone derivative and lipoxygenase inhibitor with an IC₅₀ of 67.5 μM. 2'-Hydroxy-3,4-dimethoxychalcone acts as a radical scavenger that scavenges DPPH stable free radical, superoxide anion radical, and hydroxyl radical. 2'-Hydroxy-3,4-dimethoxychalcone scavenges hydrogen peroxide and inhibits linoleic acid lipid peroxidation. 2'-Hydroxy-3,4-dimethoxychalcone can be used for research on oxidative damage and inflammatory diseases.

(2S,5S)-CMI-392 is the absolute configuration of CMI-392 (HY-19205A). CMI-392 is an orally active dual 5-lipoxygenase inhibitor and platelet-activating factor receptor (PAFR) antagonist, with an IC₅₀ of 10 nM for human PAF receptor and an IC₅₀ of 100 nM for rat 5-lipoxygenase. CMI-392 blocks PAF receptor binding, inhibits leukotriene synthesis, attenuates PAF-induced hemoconcentration, and suppresses arachidonic acid- and TPA-induced ear swelling in mice. CMI-392 reduces inflammatory cell infiltration, decreases MPO levels, alleviates ocular inflammation, and improves dextran sulfate sodium-induced colitis. CMI-392 can be used in the research of inflammatory and immune-related diseases such as colitis and atopic dermatitis.

FerroLOXIN-1 is a potent inhibitor of 15LOX-2 that selectively blocked production of pro-ferroptotic HOO-ETE-PE and protected against RSL3-induced ferroptosis. FerroLOXIN-1 closely interacted therein with 15LOX-2 only, and in particular with Y154, N155, W158.

SB 210661 is a potent and selective 5-lipoxygenase inhibitor.

CMI-392 (LDP-392) is an orally active dual 5-lipoxygenase inhibitor and platelet-activating factor receptor (PAFR) antagonist, with an IC₅₀ of 10 nM for human PAF receptor and an IC₅₀ of 100 nM for rat 5-lipoxygenase. CMI-392 blocks PAF receptor binding, inhibits leukotriene synthesis, attenuates PAF-induced hemoconcentration, and suppresses arachidonic acid- and TPA-induced ear swelling in mice. CMI-392 reduces inflammatory cell infiltration, decreases MPO levels, alleviates ocular inflammation, and improves dextran sulfate sodium-induced colitis. CMI-392 can be used in the research of inflammatory and immune-related diseases such as colitis and atopic dermatitis.
