(+/-)12-HETE

(±)12-HETE is one of the six monohydroxy fatty acids produced by the non-enzymatic oxidation of arachidonic acid. The biological activity of (±)12-HETE is similar to that of its constituent enantiomers (Item Nos. 34560 and 34570). It aggregates neutrophils with an EC₅₀ value of 40 nM.

12-HETE, a major metabolic product of arachidonic acid using 12-LOX catalysis, inhibits cell apoptosis in a dose-dependent manner. 12-HETE promotes the activation and nuclear translocation of NF-κB through the integrin-linked kinase (ILK) pathway[1].12-HETE has both anti-thrombotic and pro-thrombotic effects[2]. 12-HETE is a neuromodulator[3].

ChEBI: (5Z,8Z,10E,14Z)-12-hydroxyicosatetraenoic acid is the (5Z,8Z,10E,14Z)-stereoisomer of 12-HETE. It has a role as a mouse metabolite. It is a conjugate acid of a 12-HETE(1-).
