12hetre

12(S)-HETrE是一种内源性代谢物，由血小板中的12-脂氧合酶（12-LOX）氧化ω-6 PUFA dihomo-γ-linolenic acid(DGLA)产生，作用于Gαs偶联的G蛋白偶联受体，具有抗血栓形成的作用，在心血管疾病具有潜在的治疗作用。12(S)-HETrE 在体外可抑制激动剂介导的血小板活化（IC50 = 40 μM）、α 颗粒分泌、整合素 αⅡbβ3 活化、Rap1 活化和凝血酶诱导的血块回缩。

5(S)-HETrE is produced by the action of 5-LO when mead acid is the substrate. There are no literature reports of the biological activity or further metabolic fate of 5(S)-HETrE.

8(S)-HETrE is a monohydroxy polyunsaturated fatty acid produced by rabbit neutrophil lipoxygenase when dihomo-γ-linolenic acid is used as a substrate. Although the biological activities of 8(S)-HETrE have not been well characterized, it is expected to behave similarly to 8(S)-HETE .

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.
