Resolvin E1
Resolvin E1 is a resolvin, a bioactive oxygenated product of EPA (eicosapentaenoic acid). It is a inflammation-resolving lipid mediator. RvE1 reduces neutrophil hyper-function, it also prevents the initiation and progression of tissue destruction (PMID: 16373400). RvE1, can also act as a host response modulator in the control of the inflammatory diseases that also involve bone loss such as periodontitis and arthritis. RvE1 has been shown to display specific binding sites on human neutrophils with an apparent Kd of 47 nM (PMID: 15753205; 16373400). RvE1 is a potent modulator of leukocytes as well as selective platelet responses in blood and platelet-rich plasma (PMID: 18480426).

Resolvin E2
A member of the class of resolvins that is (6E,8Z,11Z,14Z,16E)-icosapentaenoic acid carrying two hydroxy substituents at positions 5 and 18 (the 5S,18R stereoisomer).
12-HEPE
12-HEPE is hydroxy derivative of 12-lipoxygenase metabolites of Eicosapentaenoic acid (EPA). 12S-HEPE participates in platelet-neutrophil interactions in a manner similar to 12S-HETE. It can also compete with endogenous arachidonic acid for 5-lipoxygenation in stimulated human neutrophils. By providing competing substrates for neutrophil 5-lipoxygenase, platelets might contribute to the antiinflammatory potential of dietary n-3 fatty acids through platelet-neutrophil interaction.

5-HEPE
5-HEPE is a major eicosanoid formed from eicosapentaenoic acid (EPA). 5-HEPE is produced in human neutrophils. The eicosanoids are a diverse family of molecules that have powerful effects on cell function. They are best known as intercellular messengers, having autocrine and paracrine effects following their secretion from the cells that synthesize them. The diversity of possible products that can be synthesized from eicosatrienoic acid is due, in part to the variety of enzymes that can act on it. Studies have placed many, but not all, of these enzymes at or inside the nucleus. In some cases, the nuclear import or export of eicosatrienoic acid-processing enzymes is highly regulated. Furthermore, nuclear receptors that are activated by specific eicosanoids are known to exist.

11R-HEPE
11(R)-HEPE is produced by the oxidation of EPA by 11(R)-LO. This enzymatic activity and the resulting 11(R)-hydroxy acid have been isolated from the sea urchin S. purpuratus [HMDB] 11(R)-HEPE is produced by the oxidation of EPA by 11(R)-LO.

15-HEPE
15-HEPE has been identified as a possible anti-inflammatory metabolite, and its elevated presence in the epidermis of animals fed oils rich in 20:5(n-3) or 18:3(n-6) may provide a mechanism for the beneficial effects of these oils on inflammatory conditions. 15-HEPE is a metabolite of eicosapentaenoic acid (EPA) which has anti-inflammatory properties and plays an important role in the resolution phase of inflammation. 15-HEPE is deposited in the epidermis, particularly in the metabolically active basal layer. This is considered advantageous in psoriasis therapy.
