Laropiprant (MK-0524) is a potent and selective antagonist of prostaglandin D2 (PGD2) receptor (DP) such as and DP DP1 receptor(Ki = 0.57 nM) and TP Receptor(Ki = 2.95 nM).

L 888607 Racemate is a selective antagonist of the prostaglandin D2 receptor subtype 1 (DP1) with Ki values of 132 nM and 17 nM for DP1 and the thromboxane A2 receptor (TP), respectively.

Nedocromil (FPL 59002) inhibits the action or formation of multiple mediators. Which including histamine, leukotriene C4 (LTC4), and prostaglandin D2 (PGD2).

O-Desmethyl-N-deschlorobenzoyl indomethacin is a metabolite of the non-steroidal anti-inflammatory drug (NSAID) and COX inhibitor indomethacin, formed from indomethacin in isolated rabbit hepatocytes. O-Desmethyl-N-deschlorobenzoyl indomethacin (600 μM) decreases the viability of HL-60 leukemia cells when cultured with glucose oxidase. It has also been used in the synthesis of prostaglandin D2 receptor antagonists.

15(R)-15-methyl Prostaglandin D2 (15(R)15methyl PGD2) is a synthetic analogue of PGD2 and a selective and potent CRTH2 DP2 receptor agonist that modulates eosinophil CD11b expression, actin polymerisation and chemotaxis.

The biological effects of prostaglandin D2 (PGD2) are transduced by at least two 7-transmembrane G protein-coupled receptors, designated DP1 and CRTH2/DP2. In humans, CRTH2/DP2 is expressed on Th2 cells, eosinophils, and basophils where it mediates the chemotactic activity of PGD2. CAY10597, as a racemic mixture, is a potent CRTH2/DP2 receptor antagonist that binds to the human receptor with a Ki value of 37 nM. The R enantiomer is slightly more potent exhibiting Ki values of 23 and 22 nM at the human and murine CRTH2/DP2 receptor, respectively. The R enantiomer of CAY10597 inhibits eosinophil chemotaxis induced by 13,14-dihydro-15-keto-prostaglandin D2 with an IC50 value of 40 nM.

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.

Pexopiprant, a potent oral antagonist of the prostaglandin D2 receptor 2 (DP2) with a K i value less than 100nM, is a valuable compound for asthma research.

AM-211 sodium is a novel and potent antagonist of the prostaglandin D2 receptor type 2. AM-211 is active in animal models of allergic inflammation. AM211 has high affinity for human, mouse, rat, and guinea pig DP2 and it shows selectivity over other prostanoid receptors and enzymes. AM211 exhibits good oral bioavailability in rats and dogs and dose-dependently inhibits 13,14-dihydro-15-keto-PGD(2)-induced leukocytosis in a guinea pig pharmacodynamic assay.

AM211 (AM211 free acid) is a potent and orally bioavailable antagonist of prostaglandin D2 (PGD2) receptor type 2 (DP2)

11-Keto Fluprostenol, a potent analog of prostaglandin F2α (PGF2α), primarily interacts with the FP receptor. It is a structurally modified derivative of prostaglandin D2 (PGD2) designed to enhance its potency and extend its half-life. The compound is produced by oxidizing fluprostenol at the C-11 position, which results in 11-keto fluprostenol. This modification allows 11-keto Fluprostenol to exhibit moderate affinity for the CRTH2/DP2 receptor, though it shows negligible activity at the DP1 receptor, distinguishing its action from that of PGD2.

15-deoxy-Δ12,14-Prostaglandin D2 (15-deoxy-Δ12,14-PGD2) is a PGD2 metabolite functioning as an agonist for the PGD2 receptor 2 (DP2), with a binding affinity (Ki) of 50 nM for the mouse DP2 receptor expressed in HEK293 cell membranes. 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.

15(R)-Prostaglandin D2 functions as a DP(2) receptor (Prostaglandin Receptor) agonist with potential roles in prostatic hormone signaling and exhibits anti-inflammatory properties. It enhances actin polymerization in human eosinophils and elevates cAMP levels in platelets [1].

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].
