Lipoxygenase
LOX
Lipoxygenases (LOXs) are a family of enzymes that are responsible for the metabolism of arachidonic and docosahexaenoic acid and for the formation of several eicosanoids and docosanoids, including leukotrienes, lipoxins and neuroprotectins. Depending on cells' redox state and other milieu conditions, these enzymes are engaged in oxidative stress and cell death mechanisms or in cell protection. Lipoxygenases are lipid peroxidizing enzymes, implicated in the pathogenesis of inflammatory and hyperproliferative diseases, which represent potential targets for pharmacological intervention.
Lipoxygenases are classified on the basis of site of arachidonate oxygenation into 5-, 8-, 9-, 11-, 12- and 15-LOX. The prominent animal LOXs are 5-LOX, 8-LOX, 12-LOX and 15-LOX, while the plant LOXs are mostly 5-LOX and 15-LOX. Among these, 5-LOX is the most predominant isoform associated with the formation of 5-hydroperoxyeicosatetraenoic acid (5-HpETE) and other bioactive lipid mediators.

Eriodictyol chalcone
0 ImagesCat. No.: HY-N9551CAS No.: 14917-41-0Eriodictyol chalcone is an antioxidant that inhibits multiple key enzymes including 5-LOX (IC50=0.043 μM), aromatase/CYP19A1 (IC50=2.8 μM), PTPase 1B (IC50=1.26 μM), and COX (IC50=34 μM). Eriodictyol chalcone exhibits excellent free radical scavenging activity. Eriodictyol chalcone not only inhibits the growth of plasmodia and enhances the efficacy of Artemisinin (HY-B0094), but also reduces depression-like behaviors in animal models. Eriodictyol chalcone serves as a biosynthetic precursor for Aureusidin (HY-N9834). Eriodictyol chalcone is a potential dietary supplement and herbicide, and it can be applied to research on malaria, depression, breast cancer and other related diseases.
