Isbogrel (CV4151) is a small molecule thromboxane A2 synthase (TXA2 synthase) inhibitor that can be used to study cardiac arrhythmias, transient ischemic attacks and thrombosis.

sulotroban is a TXA2 receptor antagonist that acts synergistically with iloprost to inhibit TXA2-dependent platelet activation.

LCB-2853 is a potent thromboxane A2 prostaglandin H2 (TXA2 PGH2) receptor antagonist with antiplatelet aggregation, antivasospasm, and antithrombotic effects.

Pirodomast is a thromboxane A (TXA2) synthase inhibitor. Pirodomast inhibits leukotriene (LT) D4, C4, E4 formation and thromboxane B2 (TXB2) activity, but is weakly or ineffectively antagonistic to guinea pig bronchospasm induced by histamine, methacholine, serotonin, LTC4, or platelet-activating factor. Pirodomast is a potential antiallergic compound. Pirodomast had only weak relaxant activity on guinea pig trachea in vitro. Pirodomast is a potential antiallergic compound that inhibits the protein hydrolyzing activity of trypsin in vitro, prevents antigen-induced immediate and late asthmatic responses in allergic sheep in vivo, and inhibits antigen-induced airway hyperresponsiveness to histamine and carbachol in allergic sheep.

Daltroban (SKF 96148) is a specific thromboxane A2 (TXA2) receptor antagonist. Daltroban shows protective effect in reperfusion injury. Daltroban increase intracellular calcium in vascular smooth muscle cells.

Imitrodast is a small molecule thromboxane A2 synthase (TXA2 synthase) inhibitor for the treatment of immune system disorders, respiratory disorders, and cardiovascular diseases, and can be used in studies of arterial thrombosis, asthma, and coronary vasospasm.

FUREGRELATE, a thromboxane A2 (TxA2) synthase inhibitor, blunts the development of pulmonary arterial hypertension in neonatal piglets.

Ozagrel (Domenan) is a selective thromboxane A(2) (TXA(2)) synthetase inhibitor with IC50 of 11 nM for rabbit platelet, used for the improvement of postoperative cerebrovascular contraction and accompanying cerebral ischaemia.

Indobufen (Ibustrin) is an inhibitor of platelet aggregation and is a reversible platelet cyclooxygenase (Cox) activity inhibitor. Indobufen suppresses thromboxane A2 (TxA2) synthesis. Indobufen down-regulates tissue factor (TF) in monocytes.

Ozagrel hydrochloride (OKY-046 HCl) is a selective thromboxane A(2) synthetase inhibitor used for the improvement of postoperative cerebrovascular contraction and accompanying cerebral ischaemia.

Ramatroban (BAY u3405) (BAY u3405) is a thromboxane A(2) (TxA(2)) antagonist marketed for allergic rhinitis. It has been used in trials studying the treatment of Asthma.

NP-313 (NSC-4264) is a potent antithrombotic agent that inhibits platelet aggregation and activation by inhibiting thromboxane A 2 synthesis and selectively inhibiting SOCC-mediated Ca2+ efflux.

TPα and TPβ are two isoforms of the human TP receptor, the G protein-coupled receptor (GPCR) that mediates the actions of thromboxane A2 (TXA2). Although their distinct physiological functions have not been fully elucidated, TPβ is believed to be responsible for vascular endothelial growth factor-induced endothelial cell differentiation and migration whereas TPα appears to be the predominant isoform expressed in platelets. CAY10535 is a TP receptor antagonist that shows ~20-fold selectivity for TPβ (IC50 = 99 nM) relative to TPα (IC50 = 1,970 nM) in the inhibition of U46619-mediated Ca2+ mobilization. This compound exhibits relatively poor activity on platelets (IC50 = 985 nM) when inhibiting U-46619-induced platelet aggregation.

U-51605, a stable analog of the endoperoxide prostaglandin H2 (PGH2), functions as an inhibitor with greater selectivity towards prostacyclin (PGI) synthase over thromboxane (TX) synthase. It also acts as a partial agonist at TP receptors. Studies show that at a concentration of 2.8 µM, U-51605 effectively inhibits PGI synthase in human foreskin fibroblasts, while a concentration of 5.6 µM is required to inhibit human platelet TX synthase. Furthermore, U-51605, at up to 1 µM, decreases the release of prostacyclin in SHR aorta triggered by the calcium ionophore A-23187 without impacting TXA2 production, and notably enhances the release of PGE2 and PGF2α.
