ent prostaglandin e2

Enzymatically-derived prostaglandin E2 (PGE2) is an optically pure compound whereas PGE2 derived from the free radical-catalyzed peroxidation of arachidonate is a racemic mixture. Ent-PGE2 is the opposite enantiomer of PGE2. Significant amounts of racemic PGE2 (rac-PGE2) are generated in vitro and in vivo in settings of oxidative stress via the isoprostane pathway. A proposed mechanism for the formation of rac-PGE2 involves the base catalyzed equilibration from 15-E2t-isoprostane (8-iso-PGE2), generated from the 15-H2t-isoprostane endoperoxide.

13,14-dihydro-15-keto Prostaglandin E2 (13,14-dihydro-15-keto PGE2) serves as the predominant metabolite of PGE2 in plasma, created through a 15-keto PGE2 intermediate by the action of 15-oxo-PG Δ13 reductase. Unlike its precursor PGE2, this compound exhibits poor binding affinity towards EP2 and EP4 PGE2 receptors (Ki values of 12 and 57 µM, respectively) in CHO cells and fails to stimulate adenylate cyclase activity therein (EC50s >18 and >38 µM, respectively). Concentrations of 13,14-dihydro-15-keto PGE2 are notably higher in the plasma of pregnant women during their third trimester and at labor and delivery stages, whereas its levels are found to be reduced in the tumor tissues of patients with non-small cell lung cancer (NSCLC) compared to adjacent healthy tissue.

Polyunsaturated fatty acids such as arachidonate and linoeate, while essential to health maintenance, are subject to random peroxidation by ambient oxygen, resulting in fragmented and reactive decomposition products. One prominent autoxidation product of either trilinolein or arachidonic acid is trans-4,5-epoxy-2(E)-decenal. One prominent autoxidation product of either trilinolein or arachidonic acid is trans-4,5-epoxy-2(E)-decenal. This aldehyde is responsible for a pungent metallic flavor of decomposed lipids, with a detection threshold of 1.5 pg/l in air.[1] trans-4,5-epoxy-2(E)-Decenal also reacts with nucleophiles (lysine amino groups) on proteins, leading to loss of cell function and viability.[2] This reactive aldehyde is therefore a useful tool in elucidating the effects of peroxidative damage in experimental models.

Prostaglandin E2 (PGE2) isopropyl ester is a more lipophilic form of the free acid, PGE2. PG esters have enhanced lipid solubility compared to their parent compounds. They are generally hydrolyzed to the free acid by endogenous esterases upon in vivo administration, making the esters useful prodrugs. In general, the C-1 esters of PGs show greatly diminished receptor activity in vitro compared to the parent free acids.

In the rat 9-deoxy-9-methylene PGE2 is equipotent to PGE2 in decreasing blood pressure. It also stimulates the gerbil colon and primate uterus at the same potency as PGE2.

11-Deoxy-16,16-dimethyl Prostaglandin E2 (11-deoxy-16,16-dimethyl PGE2) is a stable synthetic analog of Prostaglandin E2 (PGE2), acting as an agonist for both EP2 and EP3 receptors. It effectively inhibits gastric acid secretion and ulcer formation in rats, with ED50 values of 1 mg/kg and 0.021 mg/kg, respectively. This compound is also 900 times more potent than Prostaglandin F2α (PGF2α) in inducing contraction of human respiratory tract smooth muscle in vitro.

9-deoxy-9-methylene-16,16-dimethyl Prostaglandin E2 (Meteneprost) is a potent analog of prostaglandin E2 with an extended half-life in vivo.

A single intramuscular injection containing 0.5 mg of meteneprost and 7.5 mg of 17-phenyl trinor PGF1α is very effective in terminating early pregnancy. This prostaglandin mixture is ineffective on monkeys in their third trimester of pregnancy. Meteneprost, when compared to PGE2 and PGF1α, in monkey and rat, does not result in unwanted side effects such as fever or gastrointestinal problems.

(E)-2-(2-Chlorostyryl)-3,5,6-trimethylpyrazine (CSTMP) is a stilbene derivative with antioxidant and anticancer activities. It stimulates proliferation of hydrogen peroxide-damaged ECV-304 cells (EC50 = 24.9 nM). CSTMP reduces hydrogen peroxide-induced release of lactate dehydrogenase (LDH) in and increases viability of human umbilical vein endothelial cells (HUVECs) in a concentration-dependent manner via inhibition of apoptosis. It reverses hydrogen peroxide-induced release of malondialdehyde (MDA) and decreases in superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities as well as increases constitutive nitric oxide synthase (cNOS) activity and nitric oxide (NO) production in HUVECs. CSTMP also induces cell death of A549 non-small cell lung cancer (NSCLC) cells in an IRE1α-dependent manner through induction of IRE1α-TRAF2-ASK1 complex-mediated endoplasmic reticulum (ER) stress and mitochondrial apoptosis.

20-Ethyl Prostaglandin E2 (20-ethyl PGE2) is an analog of Prostaglandin E2 (PGE2) characterized by an extended ω-chain due to two additional methylene carbon atoms. Compared to unoprostone, a clinically approved glaucoma medication and the only extensively studied prostaglandin analog sharing this structural modification, 20-ethyl PGE2 maintains the natural 15(S) allylic hydroxyl in its lower side chain, potentially enhancing its effectiveness. Unoprostone, despite being an F-series prostaglandin, exhibits reduced affinity for FP receptors because of its lower side chain modifications (13,14-dihydro-15-keto), which diminishes its medicinal potency. Notably, 20-ethyl PGE2's efficacy relative to unoprostone and its interaction with EP or other prostanoid receptors remains unconfirmed due to the lack of published ligand binding assays. E-type prostaglandins, including 20-ethyl PGE2, are broadly acknowledged for their inflammatory, cytoprotective, and diverse biological activities.

19(R)-hydroxy Prostaglandin E2 (19(R)-hydroxy PGE2), present in the semen of primates, including humans, acts as a potent smooth muscle relaxant and is a selective agonist for the EP2 receptor. It exhibits an EC50 value of 200 nM for relaxing cat tracheal rings that express EP2 receptors.

Sphingosine-1-phosphate (S1P), a bioactive lipid crucial in numerous signaling pathways, undergoes irreversible degradation by membrane-bound S1P lyase, producing (E)-2-Hexadecenal, a derivative of sphingolipid breakdown. This compound can be oxidized to (2E)-hexadecenoic acid by long-chain fatty aldehyde dehydrogenase before being activated through linkage to coenzyme A. Notably, (E)-2-Hexadecenal induces cytoskeletal reorganization, leading to cell rounding, detachment, activation of JNK pathway targets, and ultimate apoptosis in a variety of cell types. Furthermore, it readily forms aldehyde-derived DNA adducts through reactions with deoxyguanosine and DNA.
