2,3-dinor-11β-Prostaglandin F2α (2,3-dinor-11β-PGF2α) was recovered from the urine of both normal monkeys and humans when infused with radiolabeled PGD2, where it represented approximately 1% and 4% of the infused radiolabeled dose, respectively. 2,3-dinor-11β-PGF2α has also been recovered from the urine of mastocytosis patients, where it is excreted in large amounts. In human asthmatic patients, 2,3-dinor-11β-PGF2α represents about 40% (as determined by GC/MS) of the immunoreactive 11β-PGF2α when measured using 's 11β-PGF2α EIA Kit . The excretion rate for 2,3-dinor-11β-PGF2α is approximately 200-250 ng/24 hours in a normal adult.

12(S)-HETE is a product of arachidonic acid metabolism through the 12-lipoxygenase pathway. It is primarily found in platelets, leukocytes, and to a lesser extent in smooth muscle cells. It enhances tumor cell adhesion to endothelial cells, fibronectin, and the subendothelial matrix. tetranor-12(S)-HETE is the major β-oxidation product resulting from peroxisomal metabolism of 12(S)-HETE in numerous tissues, and Lewis lung carcinoma cells. No biological function has yet been determined for tetranor-12(S)-HETE. Some data indicate it may play a role in controlling the inflammatory response in injured corneas. In some diseases (e.g., Zellweger's Syndrome) peroxisomal abnormalities result in the inability of cells to metabolize 12(S)-HETE, which may be responsible for symptoms of the disease. The tetranor derivative of 12(S)-HETE is available as a research tool for the elucidation of the metabolic fate of its parent compound.

Metabolism of 12(R)-HETE in corneal tissue produces predominantly the compound resulting from the loss of four carbon atoms through β-oxidation from C-1. This metabolite is 8(R)-hydroxy hexadecatrienoic acid (8(R)-HHxTrE) or 2,3,4,5-tetranor 12(R)-HETE.

1dinor-12-oxo-Phytodienoic acid (dinor-OPDA) serves as an intermediate in the biosynthesis of jasmonic acid from hexadecatrienoic acid, playing a crucial role in the jasmonate pathway in plants. This pathway oxygenates and modifies certain unsaturated fatty acids to produce plant hormones critical for processes such as senescence, flower development, mechanotransduction, and response to herbivory. Additionally, dinor-OPDA can be incorporated into glycerolipids and galactolipids, including specific arabidopsides.

Donecopride is a partial agonist of the serotonin (5-HT) receptor subtype 5-HT4E(Ki= 8.5 nM) and an inhibitor of acetylcholinesterase (AChE; IC50= 16 nM).1It is selective for AChE over butyrylcholinesterase (BChE; IC50= 3,530 nM) but does bind to 5-HT2Band sigma-2 (σ2) receptors (Ki= 1.6 nM for both) in a panel of 42 neurotransmitter receptors and transporters. Donecopride induces release of soluble amyloid precursor protein-α (sAPP-α) in COS-7 cells transiently expressing 5-HT4with an EC50value of 11.3 nM. Oral administration of donecopride (1 mg/kg) reduces brain soluble and insoluble amyloid-β (1-42) levels and increases the time spent exploring the novel object in the novel object recognition (NOR) test in the 5XFAD transgenic mouse model of Alzheimer's disease. Donecopride (3 mg/kg, p.o.) prevents a reduction in spontaneous alternation behavior induced by intracerebroventricular administration of soluble Aβ42 (sAβ42) in the Y-maze in mice.2 1.Lecoutey, C., Hedou, D., Freret, T., et al.Design of donecopride, a dual serotonin subtype 4 receptor agonist/acetylcholinesterase inhibitor with potential interest for Alzheimer's disease treatmentProc.
