lxa 4

Lipoxin A4 (LXA4) 是一种内源性脂氧合酶衍生的类花生酸介质，具有抗炎作用。Lipoxin A4 通过抑制 Nrf2 来减弱 MSU 晶体诱导的 NLRP3 炎症小体激活，通过 FPR2-IRF 途径调节 M1 M2 巨噬细胞极化。Lipoxin 抑制氧化应激和炎症。

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.
