arachidonic

Arachidonic acid leelamide is a phospholipase A2 inhibitor. Phospholipase A is a hydrolase responsible for the release of arachidonic acid from the sn2 position of phospholipids. The released arachidonic acid is then converted to mediators of inflammation

20-carboxy Arachidonic acid (20-COOH-AA) is the major metabolite of 20-HETE that is produced in renal tubular epithelial, endothelial, and microvascular smooth muscle cell cultures. This ω-oxidation conversion can take place using purified alcohol dehydrogenases three and four or by microsomes containing recombinant human CYP4F3B. Like 20-HETE, 20-COOH-AA inhibits ion transport in the kidneys. It also produces vasorelaxation of porcine coronary microvessels constricted with endothelin. 20-COOH-AA binds to isolated ligand binding domains of peroxisome proliferator-activated receptor α (PPARα) (Kd = 0.87 ± 0.12 μM) and PPARγ (Kd = 1.7 ± 0.5 μM), and is a dual activator of PPARα and PPARγ in a transiently transfected COS-7 cell reporter system.

5,6-dehydro Arachidonic acid is an analog of arachidonic acid with an acetylene in the 5,6 position. It inhibits 5-LO in rat basophilic leukemia cells, with a Ki value of 15 μM. In guinea pig leukocytes, 5-LO is inhibited by 5,6-dehydro arachidonic acid with an IC50 value of 10 μM.

It is formed by the synthesis from dietary linoleic acid and is a precursor in the biosynthesis of prostaglandins, thromboxanes, and leukotrienes.

Omega-3 Arachidonic Acid ethyl ester, a rare polyunsaturated fatty acid with limited presence in dietary sources, is crucial for infant growth and development and offers protection against heart disease, blood clots, high blood pressure, and inflammatory and autoimmune disorders. In human platelet membranes, it impedes arachidonyl-CoA synthetase, exhibiting a Ki of 14 μM, and shows similar inhibitory effects on arachidonoyl-CoA synthetase in calf brain extract with an IC50 of roughly 5 μM. The ethyl arachidonate derivative offers enhanced lipophilicity compared to its free acid counterpart.

Arachidonic acid sodium salt (Immunocytophyt), a polyunsaturated omega-6 fatty acid, is a key component of biomembranes and serves as a substrate for different lipid mediators, like prostaglandins (PGs). It enhances cognitive and cardiovascular functions [1].

ω-3 Arachidonic acid, a poly fatty acid essential for infant growth and development, inhibits arachidenol-CoA synthetase with Ki values of 14 µM and shows an IC50 of approximately 5 µM in calf brain extract [1] [2].

Omega-3 Arachidonic Acid methyl ester, primarily represented by docosahexaenoic acid, eicosapentaenoic acid, and α-linolenic acid, is an essential dietary nutrient crucial for normal growth and development. It is the neutral, fat-soluble form of the rare fatty acid, ω-3 Arachidonic Acid. The ω-3 fatty acids group is associated with reduced inflammation and autoimmune activity, as well as decreased thrombosis and platelet activation.

20-HETE promotes cell proliferation and migration in cancer and can be used to study prostate tumors and cardiac hypertrophy by activating the protein kinase C pathway to increase FBXO10 expression.20-HETE promotes cell proliferation and migration in cancer and can be used to study prostate tumors and cardiac hypertrophy by activating the protein kinase C pathway.

AACOCF3 (Arachidonyl trifluoromethyl ketone) is a cell-permeable trifluoromethyl ketone analog of arachidonic acid and a potent, selective slow binding inhibitor of the 85-kDa cytosolic phospholipase A2 (cPLA2). By blocking the production of arachidonate and 12-hydroxyeicosatetraenoic acid in calcium ionophore-challenged platelets, AACOCF3 hinders their synthesis. Additionally, AACOCF3 inhibits glucose-induced insulin secretion from isolated rat islets, making it promising for cardiovascular disease research.

CJ-13,610 is an orally active and nonredox-type inhibitor of 5-lipoxygenase (5-LOX). CJ-13,610 inhibits the biosynthesis of leukotriene B4 and regulates the expression of IL-6 mRNA in macrophages.

Leukotriene D4 (LTD4) is a potent pro-inflammatory mediator formed from arachidonic acid, a bronchoconstrictor, and induces osteoclast senescence.Leukotriene D4 induces transcriptional activity of potentially oncogenic genes and can be used in the study of asthma.

ALOX15-IN-2 is a potent inhibitor of ALOX15 linoleate oxygenase activity, inhibiting the oxidation of linoleic acid (LA) and arachidonic acid (AA), the immediate homologs of ALOX15, with IC50s of 1.55 and 2.79 μM, respectively.

Zoliprofen is a potent and orally available non-steroidal anti-inflammatory agent with anti-inflammatory, antipyretic and analgesic activity, and inhibits carobolin, mycobacterium, and knife-ball protein A-induced rat paw oedema, as well as anti-rat serum-induced fracture or dorsal skin oedema. Zoliprofen is 20 times more effective than ibuprofen and fenoprofen against collagen- or arachidonic acid-induced platelet aggregation in rats and rabbits. Zoliprofen was 20 times more effective than ibuprofen and fenoprofen in inhibiting endotoxin-induced diarrhoea in mice and arachidonic acid-induced acute mortality in rabbits.

BIRM 271 is a novel arachidonic acid release inhibitor that blocks leukotriene B4 and platelet-activating factor biosynthesis in human neutrophils. BIRM 271 and BIRM 270 are enantiomers that inhibit the production of leukotriene B4 with IC50 of 40 nM.

Diclofenac (Diclofenacum) is a nonsteroidal benzeneacetic acid derivative with anti-inflammatory activity. Diclofenac binds and chelates both isoforms of cyclooxygenase (COX-1 and-2), thereby blocking the conversion of arachidonic acid to pro-inflammatory-proprostaglandins.

Idebenone (CV-2619) is a synthetic analogue of ubiquinone (Coenzyme Q10), a vital cell antioxidant and essential component of the Electron Transport Chain (ETC).

Loxoprofen sodium (CS-600) is an effective and oral sodium inhibitor of COX-1 and COX-2 with IC50 of 6.5 and 13.5 μM, respectively.

Zileuton (A 64077) is a synthetic derivative of hydroxyurea with antiasthmatic properties. The leukotriene inhibitor zileuton blocks 5-lipoxygenase, which catalyzes the formation of leukotrienes from arachidonic acid; causes bronchodilation; decreases bronchial mucous secretion and edema; and may prevent or decrease the symptoms of asthma.

Desonide (Prednacinolone) is a synthetic glucocorticosteroid for topical use, with anti-inflammatory activity. Desonide binds to glucocorticoid receptors in the cytoplasm, and the ligand-receptor complex is translocated as a homodimer into the nucleus, where transcription activation via glucocorticoid response elements within glucocorticoid-responsive genes occur. This agent induces transcription of genes coding for anti-inflammatory proteins, including lipocortin-1, interleukin-10, interleukin-1 receptor antagonist and neutral endopeptidase. Increased synthesis of lipocortin-1 has an inhibitory effect on phospholipase A2, which in turn inhibits the release of arachidonic acid, thereby controlling the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes.
