Fatty acids have many health benefits in a great variety of diseases ranging from cardiovascular to cerebral diseases. For instance, docosahexaenoic acid (DHA), which is highly enriched in brain phospholipids, plays a major role in anti-inflammatory or neuroprotective pathways. Its effects are thought to be due, in part, to its conversion into derived mediators such as protectins. 1-Lyso,2-docosahexaenoyl-glycerophosphocholine (LysoPtdCho-DHA) is one of the physiological carrier of DHA to the brain. We previously synthesized a structured phosphatidylcholine to mimic 1-lyso,2-docosahexaenoyl-glycerophosphocholine, named AceDoPC® (1-acetyl,2-docosahexaenoyl-glycerophosphocholine), that is considered as a stabilized form of the physiological LysoPtdCho-DHA and that is neuroprotective in experimental ischemic stroke. Considering these, the current study aimed at enzymatically oxygenate DHA contained within AceDoPC® to synthesize a readily structured oxidized phospholipid containing protectin DX (PDX), thereafter named AceDoxyPC (1-acetyl,2-PDX-glycerophosphocholine). Identification of this product was performed using liquid chromatography/tandem mass spectrometry. Such molecule could be used as a bioactive mediator for therapy against neurodegenerative diseases and stroke.
