Epoprostenol sodium is used in pulmonary hypertension and transplantation as a potent inhibitor of platelet aggregation.

12-HETE, a major metabolic product of arachidonic acid using 12-LOX catalysis, inhibits cell apoptosis in a dose-dependent manner. 12-HETE promotes the activation and nuclear translocation of NF-κB through the integrin-linked kinase (ILK) pathway.12-HETE has both anti-thrombotic and pro-thrombotic effects. 12-HETE is a neuromodulator.

16,16-Dimethyl prostaglandin E2 (16,16-dimethyl PGE2) is an orally active vertebrate Hematopoietic stem cells (HSCs) homeostasis critical regulator. 16,16-Dimethyl prostaglandin E2 can act through EP2/EP4 and has an interaction with the Wnt pathway.

Leukotriene B4 (LTB4) is known as one of the most potent chemoattractants and activators of leukocytes and is involved in inflammatory diseases. Leukotriene B4 is also an alkyl chain-based PROTAC linker that can be used in the synthesis of PROTACs.

Bimatoprost is a prostaglandin analog that reduces intraocular pressure by regulating scleral and trabecular outflow. Bimatoprost is used in the study of open-angle glaucoma, ocular hypertension, and other forms of glaucoma. Topical application of bimatoprost induces fat atrophy and causes a deepening of the eyelid sulcus.

Lipoxin A4 (LXA4), an endogenous lipoxygenase-derived eicosanoid mediator, has potent dual pro-resolving and anti-inflammatory properties. Lipoxin A4 inhibits proliferation and inflammatory cytokine/chemokine production of human epidermal keratinocytes (NHEKs) associated with the ERK1/2 and NF-kB pathways. Lipoxin A4 inhibits serum amyloid A (SAA)-mediated IL-8 release with an IC₅₀ value of 25.74 nM.

15(S)-HPETE is a precursor of 15(S)-HETE (HY-113336). 15(S)-HPETE is a product of Arachidonic acid (HY-109590) in the 15-lipoxygenase pathway. 15(S)-HPETE reduces Bcl-2, Akt, and phosphorylated Akt protein levels. 15(S)-HPETE induces Apoptosis. 15(S)-HPETE antagonizes the angiogenic effects of 15(S)-HETE. 15(S)-HPETE exhibits antitumor effects against chronic myeloid leukemia. 15(S)-HPETE can be used in adipose tissue explant studies.

15-Deoxy-Δ-12,14-prostaglandin J2 (15d-PGJ2) is a cyclopentenone prostaglandin and a metabolite of PGD2. 15-Deoxy-Δ-12,14-prostaglandin J2 is a selective PPARγ (EC₅₀ of 2 µM) and a covalent PPARδ agonist. 15-Deoxy-Δ-12,14-prostaglandin J2 promotes efficient differentiation of C3H10T1/2 fibroblasts to adipocytes with an EC₅₀ of 7 μM.

15-keto-Prostaglandin E2 (15-keto-PGE2) is an endogenous PGE₂ metabolite. 15-keto-Prostaglandin E2 inhibits STAT3 activation by binding to the Cys259 residue of STAT3. 15-keto-Prostaglandin E2 binds to and stabilizes EP2 and EP4 receptors. 15-keto-Prostaglandin E2 inhibits the growth and progression of breast cancer cells. 15-keto-Prostaglandin E2 activates PPAR-γ and promotes fungal growth. 15-keto-Prostaglandin E2 disrupts glomerular vascularization during zebrafish development and reduces the surface area of the glomerular filtration barrier.

(±)11(12)-EET is a NLRP3 inflammasome inhibitor. (±)11(12)-EET can be used for the research of anti-inflammatory, angiogenic and cardioprotective.

5,6-Epoxyeicosatrienoic acid (5,6-EET; (±)5,6-EpETrE) is a fully racemic version of the enantiomeric forms biosynthesized from arachidonic acid by cytochrome P450 enzymes. In solution, 5,6-Epoxyeicosatrienoic acid degrades into 5,6-DiHET and 5,6-δ-lactone, which can be converted to 5,6-DiHET and quantified by GC-MS. In neuroendocrine cells, such as the anterior pituitary and pancreatic islets, 5,6-Epoxyeicosatrienoic acid has been implicated in the mobilization of calcium and hormone secretion. 5,6-Epoxyeicosatrienoic acid is an inhibitor of T-type voltage-gated calcium channels (Cav3) that inhibits isoforms Cav3.1, Cav3.2 (IC₅₀=0.54 μM), and Cav3. and decreases nifedipine-resistant phenylephrine-induced vasoconstriction in isolated mouse mesenteric arteries via Cav3.2 blockade when used at a concentration of 3 μM. In addition, it is a substrate of COX-1 and COX-2.

Leukotriene C4 is a eicosanoid lipid mediator and produced by immune cells during type 2 inflammation. Leukotriene C4 can mediate inflammation,allergy, bronchoconstriction, and vascular leakage.
