Misoprostol is a widely sold analog of PGE1 which has potent but relatively non-selective agonist activity with respect to the prostanoid EP receptor subgroup. Misoprostol has been used therapeutically for many years in humans for the treatment of gastric ulcer disease under the Searle tradename…

A plant growth regulator that activates various signal transduction pathways with both growth promoting and inhibitory functions, perhaps in response to stress; initially synthesized as (+)7-epi jasmonic acid, a more active and biologically relevant form of the hormone, but quickly epimerizes to…

The physiological actions of PGD2 include regulation of sleep, lowering of body temperature, inhibition of platelet aggregation and relaxation of vascular smooth muscle. PGD2 mediates its effects by 2 distinct G-protein-coupled receptors, DP1 and CRTH2/DP2. 15(R)-15-methyl PGD2 is a potent,…

PGD2 is one of the five primary enzymatic prostaglandins derived directly from PGH2. PGD2 is produced abundantly in the CSF by the lipocalin-type PGD synthase, and in the periphery by myeloid cells including mast cells and basophils by a second, hematopoietic-type PGD synthase. PGD2 is chemically…
