(±)15-HEPE is a racemic mixture of the monohydroxy fatty acids 15(R)-HEPE and 15(S)-HEPE . 15(S)-HEPE is formed from EPA via a 15(S)-HpEPE intermediate, which is produced by 15-lipoxygenase (15-LO) and reduced by glutathione peroxidase (GPX).1,2 (±)15-HEPE is active against P. acnes and S. aureus (MICs = 128 and 512 mg/L, respectively).3 It inhibits aggregation of isolated rat neutrophils induced by the formyl peptide receptor agonist fMLP (IC50 = 4.7 μM).4 Bronchoalveolar lavage fluid (BALF) levels of (±)15-HEPE are increased in patients with allergic asthma or COVID-19.5,6 | [Definition]
ChEBI: 15-HEPE is a hydroxyicosapentaenoic acid that consists of 5Z,8Z,11Z,13E,17Z-eicosapentaenoic acid bearing an additional 15-hydroxy substituent. It has a role as a mouse metabolite. It is a HEPE and a hydroxy polyunsaturated fatty acid. | [References]
