15(S)-HETrE is the hydroxy-trienoic acid resulting from 15-lipoxygenation of dihomo-γ-linolenic acid . It is an inhibitor of 5-LO in human PMNL with an IC50 value of 4.6 µM. In RBL cells, 15(S)-HETrE inhibits 5-LO, but is about 1/20 as potent as 15(S)-HpETE.

15-lipoxygenase metabolites of gamma-linolenic acid/eicosapentaenoic acid suppress growth and arachidonic acid metabolism in human prostatic adenocarcinoma cells: possible implications of dietary fatty acids
Prostaglandins Leukot Essent Fatty Acids 2005 May;72(5):363-72.PMID:15850718DOI:10.1016/j.plefa.2005.02.002.
Although gammalinolenic acid (GLA) and eicosapentaenoic acid (EPA) have independently been reported to suppress growth of cancer cells, their relative potencies are unknown. To determine the possible attenuating efficacies of dietary GLA or EPA on prostate carcinogenesis, we hereby report the in vitro effects of GLA, EPA and their 15-lipoxygenase (15-LOX) metabolites: 15(S)-HETrE and 15(S)-HEPE, respectively, on growth and arachidonic acid (AA) metabolism in human androgen-dependent (LNCaP) and androgen-independent (PC-3) prostatic cancer cells in culture. Specifically, both cells were preincubated respectively with the above PUFAs. Growth was determined by [3H]thymidine uptake and AA metabolism by HPLC analysis of the extracted metabolites. Our data revealed increased biosynthesis of prostaglandin E2 (PGE2) and 5-hydroxyeicosatetraenoic acid (5(S)-HETE) by both cells. Preincubation of the cells with 15(S)-HETrE or 15(S)-HEPE more markedly inhibited cellular growth and AA metabolism when compared to precursor PUFAs. Notably, 15(S)-HETrE exerted the greatest inhibitory effects. These findings therefore imply that dietary GLA rather than EPA should better attenuate prostate carcinogenesis via its in vivo generation of 15(S)-HETrE, thus warranting exploration.
Soluble epoxide hydrolase in the generation and maintenance of high blood pressure in spontaneously hypertensive rats
Am J Physiol Endocrinol Metab 2011 Apr;300(4):E691-8.PMID:21266668DOI:10.1152/ajpendo.00710.2010.
We hypothesized that perinatal inhibition of soluble epoxide hydrolase (SEH), which metabolizes epoxyeicosatrienoic acids in the arachidonic acid (AA) cascade, with an orally active SEH inhibitor, 12-(3-adamantan-1-yl-ureido)-dodecanoic acid (AUDA), would persistently reduce blood pressure (BP) in adult SHR despite discontinuation of AUDA at 4 wk of age. Renal cytoplasmic epoxide hydrolase-2 (Ephx2) gene expression was enhanced in SHR vs. WKY from 2 days to 24 wk. Effects of perinatal treatment with AUDA, supplied to SHR dams until 4 wk after birth, on BP in female and male offspring and renal oxylipin metabolome in female offspring were observed and contrasted to female SHR for direct effects of AUDA (8-12 wk). Briefly, inhibition of SEH was effective in persistently reducing BP in female SHR when applied during the perinatal phase. This was accompanied by marked increases in major renal AA epoxides and decreases in renal lipoxygenase products of AA. Early inhibition of SEH induced a delayed increase in renal 5-HETE at 24 wk, in contrast to a decrease at 2 wk. Inhibition of SEH in female SHR from 8 to 12 wk did not reduce BP but caused profound decreases in renal 15(S)-HETrE, LTB4, TBX2, 5-HETE, and 20-HETE and increases in TriHOMEs. In male SHR, BP reduction after perinatal AUDA was transient. Thus, Ephx2 transcription and SEH activity in early life may initiate mechanisms that eventually contribute to high BP in adult female SHR. However, programmed BP-lowering effects of perinatal SEH inhibition in female SHR cannot be simply explained by persistent reduction in renal SEH activity but rather by more complex and temporally dynamic interactions between the renal SEH, lipoxygenase, and cyclooxygenase pathways.
[Study on intervention effect of Jieduquyuziyin prescription systemic lupus erythematosus by HPLC-Q-TOF/MS]
Zhongguo Zhong Yao Za Zhi 2013 Nov;38(21):3747-52.PMID:24494566doi
To establish a metabonomic method based on high performance liquid chromatography-quadrupole-time of flight mass spectrometry (HPLC-Q-TOF/MS), in order to study the changes in serum metabolites of systemic lupus erythematosus (SLE) mice after treatment of Jieduquyuziyin prescription, the pathogenesis of SLE and mechanism of drug action. The orthogonal partial least squares (OPLS) was applied for the pattern recognition of experimental data, finding a significant difference in the control group, the SLE model group, the Jieduquyuziyin prescription-treated group and the prednisone acetate-treated group. According to the OPLS load diagram, 12 differential metabolites, including traumatic acid, PAF, 12 (S)-HEPE, 15(S)-HETrE and Hepoxilin B3 were identified by using accurate mass combined with MS/MS data After treatment with Jieduquyuziyin prescription, the relative contents of PAF, 12 (S)-HETE were close to the level of the control group. According to the analysis on metabolic pathway, SLE could cause significant changes in unsaturated fatty acid and amino acid metabolism pathway, while Jieduquyuziyin prescription has a effect in regulating disorder of unsaturated fatty acid metabolism pathway.
