Lipoxin A5 (CAS 110657-98-2)

Lipoxin A5, identified by the CAS number 110657-98-2, is a member of the lipoxin family, which are bioactive metabolites produced from arachidonic acid primarily through the lipoxygenase pathway. This particular lipoxin is noteworthy for its involvement in modulating inflammation and immune responses at a cellular level. Structurally, Lipoxin A5 is characterized by its conjugated tetraene backbone, which is essential for its biological activity. In research, Lipoxin A5 has been extensively studied for its role in the resolution phase of inflammation, where it actively contributes to the cessation of inflammatory responses and promotes the healing process. The specific mechanisms of action of Lipoxin A5 include interaction with specific G-protein-coupled receptors on the surfaces of immune cells, such as neutrophils and macrophages. This interaction leads to the inhibition of pro-inflammatory signals and stimulation of pathways that encourage the resolution of inflammation, such as the recruitment of non-inflammatory monocytes and the enhancement of macrophage phagocytosis of apoptotic cells. Furthermore, studies have utilized Lipoxin A5 to explain pathways involved in chronic inflammation and the potential regulatory mechanisms that could be exploited to modulate immune responses in various non-clinical settings, providing valuable insights into the complex interplay of bioactive lipids in immune regulation.
