Lipoxin A4 (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 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] Analytical and biological comparisons of synthetic LXA4 with endogenously derived LXA4 have confirmed its identity as matching the natural product.[5]
