Prostanoid Receptors

Prostanoid receptor agonists and antagonists act on the G protein-coupled receptors for prostaglandins and thromboxane. Prostanoids are lipid mediators formed from arachidonic acid by cyclooxygenase enzymes. Under the 1994 classification by the International Union of Pharmacology (IUPHAR), each receptor is named after its preferred natural ligand. The receptors for prostaglandin D2 (DP), E2 (EP), F2α (FP), prostacyclin (IP) and thromboxane A2 (TP) follow this scheme. Prostaglandin E2 (PGE2) acts on four subtypes, EP1 to EP4, which couple to different G proteins. Natural agonists in this category include PGE2 and dinoprost, also called prostaglandin F2α. Antagonists include laropiprant at the DP1 receptor, ONO-AE3-208 at EP4 and CAY10471 Racemate at DP2, the second receptor for prostaglandin D2.

    BM-573

    BM-573 is an orally active dual thromboxane A₂ (TXA₂) modulator that functions through specific inhibition of thromboxane synthase (TxAS) and antagonism of thromboxane receptors (TP). With an IC50 of 1.3 nM, it effectively inhibits platelet aggregation induced by arachidonic acid or TXA₂ analogues without affecting cyclooxygenase enzymes (COX-1/COX-2), thus preserving other prostaglandin syntheses. BM-573 also demonstrates a significant inhibitory effect on U-46619-induced contractions in rat gastric fundus smooth muscle. This compound is valuable for research applications in atherosclerosis, myocardial infarction, pulmonary hypertension, and shock.
