6,9,12,15,18-Heneicosapentaenoic acid
6,9,12,15,18-Heneicosapentaenoic acid (HPA; Heneicosapentaenoic acid methyl ester) inhibits the conversion of α-linoleic acid into Arachidonic acid (HY-109590) in hepatoma cells, the activation of prostaglandin H synthase and thromboxane synthesis in isolated platelets. 6,9,12,15,18-Heneicosapentaenoic acid is weak inducer of acyl-CoA oxidase in hepatoma cells.
