Function

[PTGD2_HUMAN] Bifunctional enzyme which catalyzes both the conversion of PGH2 to PGD2, a prostaglandin involved in smooth muscle contraction/relaxation and a potent inhibitor of platelet aggregation, and the conjugation of glutathione with a wide range of aryl halides and organic isothiocyanates. Also exhibits low glutathione-peroxidase activity towards cumene hydroperoxide.^[1] ^[2] ^[3] ^[4] ^[5] ^[6] ^[7] ^[8]

Publication Abstract from PubMed

We describe the discovery of novel inhibitors of prostaglandin D2 synthase (PGDS) through fragment-based lead generation and structure-based drug design. A library of 2500 low-molecular-weight compounds was screened using 2D nuclear magnetic resonance (NMR), leading to the identification of 24 primary hits. Structure determination of protein-ligand complexes with the hits enabled a hit optimization process, whereby we harvested increasingly more potent inhibitors out of our corporate compound collection. Two iterative cycles were carried out, comprising NMR screening, molecular modeling, X-ray crystallography, and in vitro biochemical testing. Six novel high-resolution PGDS complex structures were determined, and 300 hit analogues were tested. This rational drug design procedure culminated in the discovery of 24 compounds with an IC 50 below 1 microM in the in vitro assay. The best inhibitor (IC 50 = 21 nM) is one of the most potent inhibitors of PGDS to date. As such, it may enable new functional in vivo studies of PGDS and the prostaglandin metabolism pathway.
