Lipoxin A4

Lipoxin A4 (LXA4), an endogenous lipoxygenase-derived eicosanoid mediator, has potent dual pro-resolving and anti-inflammatory properties[1]. Lipoxin A4 inhibits proliferation and inflammatory cytokine/chemokine production of human epidermal keratinocytes (NHEKs) associated with the ERK1/2 and NF-kB pathways[2]. Lipoxin A4 inhibits serum amyloid A (SAA) -mediated IL-8 release with an IC50 value of 25.74 nM[3].
