Cayman 12(S)-HpETE

12(S)-HpETE is a monohydroperoxy polyunsaturated fatty acid (PUFA) produced by the action of platelet or leukocyte 12-lipoxygenase (12-LO) on arachidonic acid.^1,2 It activates human blood leukocyte 5-LO, resulting in the synthesis of 5(S)-HETE, leukotriene B₄ (LTB₄), and 5(S),12(S)-DiHETE.¹ Rat lung metabolizes 12(S)-HpETE to 8,11,12- and 10,11,12-trihydroxyeicostrienoic acids.³ 12(S)-HpETE is the mediator of many biological functions, including induction of c-fos and c-jun, activation of AP-1, and endothelium-dependent vasoconstriction.^4,5 It mediates the inhibitory synaptic response to FMRF-amide in Aplysia sensory neurons⁶ and inhibits Ca²⁺/calmodulin-dependent protein kinase II from rat brain cortex.^7,6
