Timapiprant sodium inhibits mast cell activation of Th2 lymphocytes and eosinophils. Timapiprant sodium is a potent and selective D prostanoid receptor 2 antagonist. Timapiprant sodium potently displaces [3H] PGD2 from human recombinant DP2 (Ki=13 nM), ra
Pexopiprant, a potent oral antagonist of the prostaglandin D2 receptor 2 (DP2) with a K i value less than 100nM, is a valuable compound for asthma research.
LAS191859 is a CRTH2/DP2 antagonist with IC50 values of 7.6, 9.58, 14 and 15.5nM for recombinant guinea pig, human, rat and mouse CRTH2/DP2 receptors, respectively. LAS191859 has a residence time half-life of 21h at CRTh2 that translates into a long-lasti
Prostaglandin D2 (PGD2) is the major eicosanoid product of mast cells and is produced in large quantities by hematopoietic PGD synthase during allergic and asthmatic anaphylaxis. It causes vasodilation, flushing, hypotension, and is an inhibitor of platelet aggregation. Prostaglandin D2 methyl ester (PGD2 methyl ester) is a more lipid-soluble, cell-permeable prodrug form of PGD2. It binds to the human and mouse PGD2 receptors (DP1 and CRTH2/DP2) with 5-10 fold lower affinity than PGD2.
