12(S)-HpEPE is a monohydroperoxy polyunsaturated fatty acid produced by the action of 12-lipoxygenase on eicosapentaenoic acid. Although the biological activities of 12(S)-HpEPE have not been well characterized, it is expected to behave similarly to 12(S)-HpETE (Catalog No. 44570).
12(S)-HPEPE is a lipoxygenase product and an intermediate metabolite that leads to downregulation of PGHS-2 and has potential anti-inflammatory activity. 12(S)-HPEPE reduces interleukin 1h (IL-1h)-induced PGHS-2 expression in human lung microvascular endothelial cells[1].
ChEBI: 12(S)-HpEPE is a 12-HPEPE in which the hydroperoxy group at positions 12 has S-configuration. It has a role as a human xenobiotic metabolite. It is a conjugate acid of a 12(S)-HpEPE(1-).
