Function
HPGDS_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
Prostaglandin D(2) synthesised by the hematopoietic prostaglandin D(2) synthase has a pro-inflammatory effect in allergic asthma, regulating many hallmark characteristics of the disease. Here we describe identification of hematopoietic prostaglandin D(2) synthase inhibitors including cibacron blue, bromosulfophthalein and ethacrynic acid. Expansion around the drug-like ethacrynic acid identified a novel inhibitor, nocodazole, and a fragment representing its aromatic core. Nocodazole binding was further characterised by docking calculations in combination with conformational strain analysis. The benzyl thiophene core was predicted to be buried in the active site, binding in the putative prostaglandin binding site, and a likely hydrogen bond donor site identified. X-ray crystallographic studies supported the predicted binding mode.
