15(R)-Prostaglandin D2

Many of the effects of prostaglandin D2 (PGD2) are transduced via a traditional 7-transmembrane GPCR, the DP1 receptor. 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. 15(R)-15-methyl PGD2 is a surprisingly potent agonist at the DP2 receptor, being about 5 times more potent than PGD2 itself. 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. Formal Name: 9alpha,15R-dihydroxy-11-oxo-prosta-5Z,13E-dien-1-oic acid.
