15(s)hpete

15(S)-HpETE 是在 15-脂氧合酶途径中形成的花生四烯酸的产物，抑制血管生成。15(S)-HpETE 可在细胞中上调 CD31、E-选择素和基因选择素的表达。

1-Stearoyl-2-15(S)-HpETE-sn-glycero-3-PC is a phospholipid that contains stearic acid at the sn-1 position and 15(S)-HpETE at the sn-2 position. It is produced via oxidation of 1-stearoyl-2-arachidonoyl-sn-glycero-3-PC by 15-lipoxygenase (15-LO). 1-Stearoyl-2-15(S)-HpETE-sn-glycero-3-PC is toxic to human umbilical vein endothelial cells (HUVECs) when used at a concentration of 100 μM.

1-Stearoyl-2-15(S)-HpETE-sn-glycero-3-PE is a phospholipid that contains stearic acid at the sn-1 position and 15(S)-HpETE at the sn-2 position. It is produced via oxidation of 1-stearoyl-2-arachidonoyl-sn-glycero-3-PE by 15-lipoxygenase (15-LO). 1-Stearoyl-2-15(S)-HpETE-sn-glycero-3-PE (0.6 and 0.9 μM) increases ferroptotic cell death in wild-type and Acsl4 knockout Pfa1 mouse embryonic fibroblasts (MEFs) treated with the GPX4 inhibitor RSL3.

The lipoxins are trihydroxy fatty acids containing a 7,9,11,13-conjugated tetraene. Lipoxin A4 (LXA4) was first described as a metabolite of 15-HpETE and or 15-HETE when added in vitro to isolated human leukocytes. The material obtained in this manner consists of at least four distinct isomers: 5(S), 6(S); 5(S), 6(R); and the 11-trans and 11-cis isomers of each of these. 6(S)-LXA4 is one of the original four metabolites first identified by Serhan, Nicolaou, and Samuelsson. It was considered to be an artifact by these authors because it lacked the potency of the 5(S),6(R) isomer with respect to contraction of isolated guinea pig lung parenchymal strips. It has not been possible to isolate natural LXA4 from humans or other mammals in amounts sufficient for determination of absolute stereochemistry. Most authors refer to LXA4 as the 5(S)

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(S)-HpEDE is a monohydroperoxy polyunsaturated fatty acid produced by the action of 15-lipoxygenase on eicosadienoic acid. Although the biological activities of 15(S)-HpEDE have not been well characterized, it is expected to behave similarly to 15(S)-HpETE (Cat. No. 44720).

15(S)-HpEPE is a monohydroperoxy polyunsaturated fatty acid produced by the action of 15-lipoxygenase on eicosapentaenoic acid. Although the biological activities of 15(S)-HpEPE have not been well characterized, it is expected to behave similarly to 15(S)-HpETE (Catalog No. 44720).

Lipoxin B4 (LXB4) is a positional isomer of LXA4 produced by the metabolism of 15-HETE or 15(S)-HpETE by human leukocytes. At a concentration of 100 nM, LXB4 inhibits polymorphonuclear leukocyte (PMN) migration stimulated by leukotriene B4 and inhibits LTB4-induced adhesion of PMNs with an IC50 value of 0.3 nM.
