It easily decomposes in the solution of ammonium acetate, carbonates, citrates or alkali metal hydroxides. It is believed that the primary mechanism of action is the irreversible acetylation of cyclooxygenase, which results in the inability to synthesize prostaglandins, prostacyclins, and thromboxane. Lipoxins halt neutrophil recruitment, adhesion, and infiltration;150–152 reduce expression of genes upregulated by inflammatory responses;153–156 stimulate prostacyclin157 and nitric oxide generation;158 and reduce angiogenesis.159–161 Many of the anti-inflammatory effects of LXA4 and 15-epi-LXA4 are mediated by expression of suppressor of cytokine signaling-2 (SOCS-2),162 which is activated by binding of these ligands to ALX, a GPCR,155 and the aryl hydrocarbon receptor, a nuclear receptor.163 In addition to these direct actions, there is evidence for cross talk with the leukotriene B4 receptor164 and growth factor receptors.159,165 15-Epi-LXA4 may account for some of the anti-inflammatory effects and beneficial cardiovascular outcomes associated with low-dose ASA treatments.

ASA irreversibly inhibits prostaglandin biosynthesis by acetylation of PGHS.10,138 The acetyl group of ASA is transferred to the active site residue Ser530.139–142 Although Ser530 is not required for catalysis, covalent modification of this residue completely blocks arachidonic acid metabolism by PGHS-1143 by hindering substrate access to Tyr385.144 Unlike PGHS-1, ASA-acetylated PGHS-2 is still able to metabolize arachidonic acid, but it produces 15-HETE instead of prostaglandins.143 Unmodified PGHS-2 generates small amounts of 15S-HpETE in the course of catalysis, but acetylated PGHS-2 produces 15R-HpETE with no detectable S-isomer, as is observed with S530M PGHS-2.133,134,145,146 The extra space of the side pocket allows PGHS-2 to bind arachidonic acid in a productive conformation for subsequent conversion to 15R-HpETE.147 V434I/R513H/V523I PGHS-2 is a triple mutant that replaces the conserved substitutions in this pocket with the corresponding PGHS-1 consensus residues.
