Description
(±)18-HEPE is produced by non-enzymatic oxidation of eicosapentaenoic acid (EPA; Item Nos.

21908). 18-HEPE levels are increased in the plasma and heart, as well as in the supernatant of cultured peritoneal macrophages isolated from
fat-1 transgenic mice that are capable of endogenously producing ω-3 fatty acids from ω-6 fatty acids. It reduces increases in cardiac fibrosis and the expression of
Nppa,
Col1a1,
Tgfb1,
Cx3cl1, and
Adgre1 induced by transverse aortic constriction in a mouse model of cardiac hypertrophy when administered at doses of 1 and 5 μg.
Uses
18-Hydroxy-(5Z,8Z,11Z,14Z,16E)-eicosapentaenoic Acid is produced by non-enzymatic oxidation of Eicosapentaenoic Acid (E477800).
Definition
ChEBI: 18-HEPE is a hydroxyicosapentaenoic acid that consists of 5Z,8Z,11Z,14Z,16E-icosapentaenoic acid with the hydroxy group located at position 18. It has a role as a human xenobiotic metabolite. It is a conjugate acid of a 18-HEPE(1-).
