Cardiovascular Disease

BM-573 is an orally active dual thromboxane A₂ (TXA₂) modulator with an IC50 of 1.3 nM. BM-573 possesses both thromboxane synthase (TxAS) inhibition and thromboxane receptor (TP) antagonistic effects. BM-573 can completely inhibit platelet aggregation induced by Arachidonic acid (HY-109590) or U-46619 (TXA₂ analogues). BM-573 completely blocks the generation of TXB₂ (the stable metabolite of TXA₂) in human platelets and does not inhibit cyclooxygenase (COX-1/COX-2), thus avoiding interference with other prostaglandin synthesis. BM-573 has an inhibitory effect on U-46619-induced contractions in rat gastric fundus smooth muscle (ED₅₀ = 4.2 μM), but has no effect on contractions caused by PGE₂, PGF₂α, or PGI₂. BM-573 can be used in the study of atherosclerosis, myocardial infarction, pulmonary hypertension and shock .
