TAS 205

TAS 205 is an inhibitor of hematopoietic prostaglandin D synthase (H-PGDS, IC50 = 55.8 nM). It is selective for H-PGDS over lipocalin-type PGDS (L-PGDS) at 100 µM, as well as over enzyme and receptor panels at 10 µM. TAS 205 inhibits production of prostaglandin D2 (PGD2, Cay-12010) induced by A23187 (Cay-11016) in KU812 human and RBL-2H3 rat basophils with IC50 values of 78.3 and 181.3 nM, respectively. It inhibits ovalbumin-induced nasal lavage fluid eosinophil infiltration and late-phase nasal obstruction in an ovalbumin-sensitized guinea pig model of allergic rhinitis when administered at a dose of 30 mg/kg.Formal Name: 4-[(1-methyl-1H-pyrrol-2-yl)carbonyl]-N-[4-[4-(4-morpholinylcarbonyl)-1-piperidinyl]phenyl]-1-piperazinecarboxamide, monohydrate.
