Lipoxygenase

Lipoxygenase (LOX) inhibitors block enzymes that insert molecular oxygen into arachidonic acid and related fatty acids. 5-Lipoxygenase (5-LOX) starts leukotriene synthesis, while 12-LOX and 15-LOX form hydroxylated lipid mediators linked to inflammation and ferroptosis. In 1990, leukotriene synthesis in intact cells was shown to require 5-lipoxygenase-activating protein (FLAP), a membrane partner of 5-LOX. The category covers both points of attack on the leukotriene pathway. Zileuton inhibits 5-LOX directly, whereas MK 886 suppresses leukotriene biosynthesis by binding FLAP. PD146176 is a 15-LOX inhibitor that also appears in ferroptosis research, where lipid peroxidation drives cell death. Baicalein, a flavone from Scutellaria baicalensis roots, is a plant-derived lipoxygenase inhibitor used across several of these models.

    13(S)-HPOTrE(γ)

    13(S)-Hydroxy-9,11,13-octadecatrienoic acid (13(S)-HPOTrE(γ) is an endogenously formed monohydroxy polyunsaturated fatty acid that serves as a substrate for soybean lipoxygenase-1 (LO-1) involved in the metabolism of γ-linolenic acid. It exhibits inhibitory effects on soybean LO-1 activity at concentrations exceeding 100 μM, and is also a precursor for the synthesis of all four isomers of 6,13-DiHOTrE. This compound is valuable for research focusing on lipoxygenase activity and the biochemical pathways involving PUFA metabolism.

    9(R)-HETE

    Synonyms: 9(R)-Hydroxyeicosatetraenoic acid

    9(R)-HETE is an enantiomer of 9-HETE, comprising 50% of the racemic mixture (±)9-HETE. It functions as an activator of RXRγ-dependent transcription, demonstrating a 1.5-fold increase in activity at a concentration of 300 nM compared to controls. The stereochemical characterization of the (R) enantiomer is supported by chiral HPLC retention time comparisons with published data. This compound is valuable for studies investigating RXR signaling pathways and lipid metabolism.
