Common Name | 15-Epi-lipoxin B5 |
---|
Description | 15-Epi-lipoxin B5 belongs to the class of organic compounds known as hydroxyeicosapentaenoic acids. These are eicosanoic acids with an attached hydroxyl group and five CC double bonds. Thus, 15-epi-lipoxin B5 is considered to be an eicosanoid lipid molecule. Lipoxins (LXs) and aspirin-triggered Lipoxin (ATL) are trihydroxytetraene-containing eicosanoids generated from arachidonic acid that are distinct in structure, formation, and function from the many other proinflammatory lipid-derived mediators. These eicosanoids (i.E., LXA4 and ATL) with a unique trihydroxytetraene structure function as 'stop signals' in inflammation and actively participate in dampening host responses to bring the inflammation to a close, namely, resolution. These endogenous eicosanoids have now emerged as founding members of the first class of lipid/chemical mediators involved in the resolution of the inflammatory response. This phenomenon is an active process that is governed by specific lipid mediators and involves a series of well-orchestrated temporal events. Lipoxin A4 (LXA4), ATL, and their metabolic stable analogs elicit cellular responses and regulate leukocyte trafficking in vivo by activating the specific receptor, ALX. 15-Epi-lipoxin B5 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Thus, potent locally released mediators serve as checkpoint controllers of inflammation. In addition to the well-appreciated ability of aspirin to inhibit PGs, aspirin also acetylates cyclooxygenase (COX)-2, triggering the formation of a 15-epimeric form of lipoxins, termed aspirin-triggered LXA4 (ATL). LXA4 and ATL elicit the multicellular responses via a specific G protein-coupled receptor (GPCR) termed ALX that has been identified in human. |
