15(S)-15-methyl Prostaglandin D2 (15(S)-15-methyl PGD2) is a metabolically stable synthetic analog of PGD2 . In contrast to PGD2, 15(S)-15-methyl PGD2 induces vasoconstriction and increases systemic blood pressure with much reduced inhibitory activity on ADP-induced platelet aggregation. It also exhibits strong antifertility activity in hamsters (200-fold more potent than PGD2).

16,16-dimethyl PGD2 is a metabolically stable synthetic analog of PGD2. It enhances ADP-induced human platelet aggregation and increases systemic blood pressure in rats.

Prostaglandin D2 (PGD2) is the major eicosanoid product of mast cells and is produced in large quantities by hematopoietic PGD synthase during allergic and asthmatic anaphylaxis. It causes vasodilation, flushing, hypotension, and is an inhibitor of platelet aggregation. Prostaglandin D2 methyl ester (PGD2 methyl ester) is a more lipid-soluble, cell-permeable prodrug form of PGD2. It binds to the human and mouse PGD2 receptors (DP1 and CRTH2 DP2) with 5-10 fold lower affinity than PGD2.

Prostaglandin D2 ethanolamide (PGD2-EA) is a bioactive lipid produced by the sequential metabolism of anandamide (arachidonoyl ethanolamide) by cyclooxygenase (COX) enzymes, in particular by COX-2, and PGD synthase. The biosynthesis of PGD2-EA from anandamide can also be increased when anandamide metabolism is diminished by deletion of fatty acid amide hydrolase. PGD2-EA is inactive against recombinant prostanoid receptors, including the D prostanoid receptor. It increases the frequency of miniature inhibitory postsynaptic currents in primary cultured hippocampal neurons, an effect which is the opposite of that induced by anandamide.. PGD2-EA also induces apoptosis in colorectal carcinoma cell lines.

It activates eosinophils with an EC50 of 8 nM and enhances the recruitment of steroid receptor coactivator-1 (SRC-1) to peroxisome proliferator-activated receptor γ (PPARγ), initiating PPARγ-mediated transcription at 5 µM concentration. Furthermore, it exhibits cytotoxicity towards L1210 murine leukemia cells with an IC50 of 0.3 µg ml and displays weaker inhibition of ADP-induced platelet aggregation than PGD2, with an IC50 of 320 ng ml.

Prostaglandin D2 (PGD2) is a primary enzymatic prostaglandin derived from PGH2 and is abundantly produced in the cerebrospinal fluid (CSF) by the lipocalin-type PGD synthase, and peripherally by myeloid cells such as mast cells and basophils via a hematopoietic-type PGD synthase. PGD2 is chemically unstable and presents challenges for use and analysis due to its brief in vivo half-life. Δ12-PGD2, an initial decomposition product of PGD2, acts as an intermediate in the pathway to Δ12-PGJ2, a cyclopentenone prostaglandin known for its antimitotic and carcinogenic properties. The metabolism of Δ12-PGD2 involves the addition of thiol nucleophiles, a common pathway for many cyclopentenone prostaglandins.

Prostaglandin D2 (PGD2) is one of the five principal prostaglandins enzymatically derived from PGH2. It is abundantly generated in the cerebrospinal fluid (CSF) by lipocalin-type PGD synthase and in peripheral regions by myeloid cells, such as mast cells and basophils, via leukocyte-type PGD synthase. The compound 1,25-trans-PGD2 is an isomer of PGD2, characterized by the alteration of the double bond between carbons 5 and 6 from cis(Z) to trans(E). This trans isomer, found as a 2-5% impurity in most commercial PGD2 bulk drug preparations, is primarily synthesized as an analytical standard to identify and quantify this impurity. Based on existing studies of trans isomers of F-type prostaglandins, 5-trans-PGD2 likely exhibits biological activity comparable to its cis isomer, although no specific published reports confirm this for 5-trans-PGD2.

13,14-Dihydro-15-keto prostaglandin D2 (DK-PGD2), a PGD2 metabolite formed by the 15-hydroxyl PGDH pathway, is a selective agonist for the DP2 receptor and can inhibit ion flux in canine colonic mucosa preparation [1].

Prostaglandin D2-1-glyceryl ester (PGD2-G; PGD2 2-glyceryl ester) is a chemical compound known for its significance in various biological processes. This compound, commonly referred to by its abbreviations PGD2-G or PGD2 2-glyceryl ester, plays a crucial role in the mediation of physiological functions.

CAY10410 is an analog of prostaglandin D2/prostaglandin J2 (PGD2/PGJ2) with structural modifications intended to give it PPARγ ligand activity and resistance to metabolism. 15-deoxy-δ12,14-PGJ2 has been shown to be a potent ligand for PPARγ. Metabolism of the cyclopentenone prostaglandins PGA2, PGJ2, and δ12-PGJ2 occurs via glutathione addition across the α,β unsaturated enone. CAY10410 was designed as an analog of the PPARγ-binding prostaglandins which could not undergo this conjugation reaction. In human neuroblastoma SH-SY5Y cells, CAY10410 was not cytotoxic at up to 25 μM. It also failed to covalently modify thioredoxin or induce oxidative stress at 50 μM.
