Description
Many of the effects of prostaglandin D2 (PGD2) are transduced via a traditional 7-transmembrane GPCR, the DP1 receptor.1 However, in certain leukocytes and other immune cells, a second PGD2 receptor referred to as the CRTH2 or DP2 receptor has been cloned and characterized.2,3 15(R)-15-methyl PGD2 is a surprisingly potent agonist at the DP2 receptor, being about 5 times more potent than PGD2 itself.4 15(R)-PGD2 has the potential to be produced endogenously as a natural ligand for DP2, unlike the synthetic 15-methyl analogs. In preliminary reports, 15(R)-PGD2 has also been reported to be a potent and selective DP2 receptor agonist.5,6
Uses
15(R)-Prostaglandin D2 is a potential prostatic hormone DP(2) receptor (Prostaglandin Receptor) agonist with anti-inflammatory activity. 15(R)-Prostaglandin D2 increases actin polymerization in human eosinophils and increases cAMP levels in platelets[1].
Definition
ChEBI: 15R-PGD2 is a prostanoid.
