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

Human H-PGDS has shown promise as a potential target for anti-allergic and anti-inflammatory drugs. Here we describe the discovery of a novel class of indole inhibitors, identified through focused screening of 42,000 compounds and evaluated using a series of hit validation assays that included fluorescence polarization binding, 1D NMR, ITC and chromogenic enzymatic assays. Compounds with low nanomolar potency, favorable physico-chemical properties and inhibitory activity in human mast cells have been identified. In addition, our studies suggest that the active site of hH-PGDS can accommodate larger structural diversity than previously thought, such as the introduction of polar groups in the inner part of the binding pocket.
