Lipoxin A4-d₅  (Synonyms: LXA4-d₅)

Lipoxin A4-d₅ is the deuterium labeled 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].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].
