S-(9-deoxy-delta9,12-PGD2)-glutathione
The major dehydration product of prostaglandin D2, 9-deoxy-d9,d12(E)-prostaglandin D2, is a potent cytotoxic compound. Like other cytotoxic prostaglandins, this compound possesses an α,β-unsaturated ketone group to which cytotoxic activity has been attributed. This prostaglandin was found to readily conjugate with glutathione (GSH) in vitro. When 9-deoxy-d9,d12(E)-prostaglandin D2 was incubated with Chinese hamster ovary or hepatoma tissue culture cells, it was rapidly taken up and was recovered in the cell lysate primarily as a GSH conjugate in which the keto group at C-11 and the Δ12 double bond had been reduced. Identification of the GSH conjugate was accomplished by analysis by fast atom bombardment mass spectrometry following purification by high performance liquid chromatography. This GSH conjugate and its cysteinylglycinyl and cysteinyl metabolites were also identified in the cell culture medium. 9-Deoxy-d9,d12(E)-prostaglandin D2 inhibited cell proliferation of these two cell lines in a concentration dependent manner. Depletion of intracellular glutathione by treatment with diethyl maleate and buthionine sulfoximine decreased the amount of intracellular conjugated prostaglandin recovered, and significantly enhanced the antiproliferative effect of 9-deoxy-d9-d12(E)-prostaglandin D2 on the growth of these cell lines in a concentration dependent fashion. Intracellular GSH may modulate the antiproliferative activity of 9-deoxy-Δ9,Δ12(E)-prostaglandin D2 and, possibly, of other cytotoxic prostaglandins.

S-(PGA2)-glutathione
S-(PGA2)-glutathione is the glutathione conjugate of prostaglanding A2. PGA2 is converted to its glutathione conjugate by human mu-class GST M1a-a. Vertebrate alpha-, mu-, and pi-class GSTs were found to enhance PGA2 conjugation with glutathione, suggesting that the overexpression of GST forms could modulate the cytotoxic effects of cyclopentenone prostaglandins. Mammalian GSTs also have the ability to non-catalytically bind lipophilic, amphipathic ligands, including PGJ2, via noncovalent interactions, which effectively sequester these ligands in the cytosol away from their nuclear targets (i.e., peroxisomal proliferator-activated receptor, PPAR). S-(PGA2)-glutathione is the glutathione conjugate of prostaglanding A2
S-(PGJ2)-glutathione
S-(PGJ2)-glutathione is a glutathione conjugate of prostaglandin J2. By reacting with glutathione and proteins, 15-d-PGJ(2) is believed to exert potent biological activity. HepG2 cells primarily convert 15-d-PGJ(2) to a glutathione conjugate in which the carbonyl at C-11 is reduced to a hydroxyl. Subsequently, the glutathione portion of the molecule is hydrolyzed with loss of glutamic acid and glycine resulting in a cysteine conjugate. These findings confirm a general route for the metabolism of cyclopentenone eicosanoids in HepG2 cells and may pave the way for new insights regarding the formation of 15-d-PGJ(2) in vivo. S-(PGJ2)-glutathione is a glutathione conjugate of prostaglandin J2.

PC(2:0/22:6(5Z,8E,10Z,13Z,15E,19Z)-2OH(7S, 17S))
PC(2:0/22:6(5Z,8E,10Z,13Z,15E,19Z)-2OH(7S, 17S)) is an oxidized phosphatidylcholine (PC or GPCho). Oxidized phosphatidylcholines are glycerophospholipids in which a phosphorylcholine moiety occupies a glycerol substitution site and at least one of the fatty acyl chains has undergone oxidation. As all oxidized lipids, oxidized phosphatidylcholines belong to a group of biomolecules that have a role as signaling molecules. The biosynthesis of oxidized lipids is mediated by several enzymatic families, including cyclooxygenases (COX), lipoxygenases (LOX) and cytochrome P450s (CYP). Non-enzymatically oxidized lipids are produced by uncontrolled oxidation through free radicals and are considered harmful to human health (PMID: 33329396). As is the case with diacylglycerols, glycerophosphocholines can have many different combinations of fatty acids of varying lengths, saturation and degrees of oxidation attached at the C-1 and C-2 positions. PC(2:0/22:6(5Z,8E,10Z,13Z,15E,19Z)-2OH(7S, 17S)), in particular, consists of one chain of one acetyl at the C-1 position and one chain of Resolvin D5 at the C-2 position. Phospholipids are ubiquitous in nature and are key components of the lipid bilayer of cells, as well as being involved in metabolism and signaling. Similarly to what occurs with phospholipids, the fatty acid distribution at the C-1 and C-2 positions of glycerol within oxidized phospholipids is continually in flux, owing to phospholipid degradation and the continuous phospholipid remodeling that occurs while these molecules are in membranes. Oxidized PCs can be synthesized via three different routes. In one route, the oxidized PC is synthetized de novo following the same mechanisms as for PCs but incorporating oxidized acyl chains (PMID: 33329396). An alternative is the transacylation of one of the non-oxidated acyl chains with an oxidated acylCoA (PMID: 33329396). The third pathway results from the oxidation of the acyl chain while still attached to the PC backbone, mainely through the action of LOX (PMID: 33329396).
