lxa-4

Lipoxin A4 (LXA4) is a lipoxygenase-derived arachidonate-like mediator with anti-inflammatory properties.Lipoxin A4 attenuates MSU crystal-induced NLRP3 inflammasome activation through inhibition of Nrf2, and regulates M1/M2 macrophage polarization through the FPR2-IRF pathway.Lipoxin inhibits oxidative stress and inflammation.

Lipoxin A4 methyl ester (LXA4 methyl ester) is a more lipid soluble, prodrug formulation of the transcellular metabolite LXA4. LXA4 is a trihydroxy fatty acid containing a conjugated tetraene, produced by the metabolism of 15-HETE or 15-HpETE with human leukocytes.[1] LXA4 is equipotent to leukotriene B4 (LTB4) in inducing superoxide generation in human neutrophils at 0.1 μM.[2] LXA4 is associated with several other biological functions including leukocyte activation, chemotaxis effects, natural killer cell inhibition, and monocyte migration and adhesion.[2],[3],[4]

BLXA-4 is used potentially to treat gingival diseases.
