Common Name | 15-Oxo-lipoxin A4 |
---|
Description | 15-Oxo-lipoxin A4, also known as 15-oxo-lxa(,4), belongs to the class of organic compounds known as lipoxins. These are eicosanoids with a trihydroxyicosatetraenoic acid skeleton (a c20-fatty acid, with the chain bearing three hydroxyl groups and four double bonds). Lipoxins have four double bonds, which are all conjugated. In some cases a hydroxyl group is substituted by a C=O group. Thus, 15-oxo-lipoxin A4 is considered to be an eicosanoid lipid molecule. This phenomenon is an active process that is governed by specific lipid mediators and involves a series of well-orchestrated temporal events. 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). 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. 15-Oxo-lipoxin A4 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Lipoxin A4 (LXA4), ATL, and their metabolic stable analogs elicit cellular responses and regulate leukocyte trafficking in vivo by activating the specific receptor, ALX. 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. |
