15(R)-Pinane thromboxane A2 is the (R)-epimer of pinane thromboxane A2 . 15(R)-PTA2 does not inhibit collagen-induced platelet aggregation (IC50s = 120-130 μM). It does not affect gastric tone in isolated rat gastric fundus when used at concentrations of 0.5 or 1.5 μg/ml and is less effective than PTA2 at inhibiting prostaglandin-induced contraction of isolated rat stomach muscle.

PTA2 is a biochemical reagent that can be used as a biomaterial for life science related research and as a sulfonylation reagent for organic synthesis and drug discovery.

Ketoprofen (RP-19583) is a propionic acid derivative and nonsteroidal anti-inflammatory drug (NSAID) with anti-inflammatory, analgesic, and antipyretic effects. It inhibits cyclo-oxygenase I and II, decreasing the formation of prostaglandin and thromboxane precursors. This reduction in prostaglandin synthesis, mediated by prostaglandin synthase, is responsible for its therapeutic effects. Additionally, Ketoprofen decreases thromboxane A2 formation via thromboxane synthase, inhibiting platelet aggregation.

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.

Imidazole-d4 is an isotope-labeled variant of imidazole, which is a heterocyclic aromatic compound. Imidazole molecules serve as inhibitors for acetylcholinesterase (AChEI) and xanthine oxidase (XO) and have been utilized as corrosion inhibitors. They display a range of biological activities, including antifungal, antitubercular, anti-inflammatory, antioxidant, and analgesic properties. Imidazole inhibits platelet microsomes from converting endoperoxides (PGG2 and PGH2) into thromboxane A2. Additionally, imidazole derivatives show inhibitory effects on the SARS-CoV-2 3CLpro enzyme, offering potential for research in Alzheimer’s disease, gout, COVID-19, and thrombotic disorders.

11-deoxy-PGF2a is a thromboxane A2 receptor agonist that partially alleviates crowding in Lpar3(−/−) female embryos and induces smooth muscle contraction in the aorta, vena cava, and trachea.

8-iso-15-keto Prostaglandin F2α (8-iso-15-keto PGF2α) is a metabolite of the isoprostane 8-iso PGF2α in rabbits, monkeys, and humans. 8-iso PGF2α is a prostaglandin-like product of non-specific lipid peroxidation. In humans and monkeys, exogenously infused 8-iso PGF2α is converted to metabolites with 2 or 4 carbon atoms removed from the top side chain by β-oxidation, with a similar pattern observed in tritiated 8-iso PGF2α-infused rabbits. Early in the infusion (within 1-2 minutes), 8-iso-15-keto PGF2α is a major component of the metabolite profile, primarily comprising unmetabolized 8-iso PGF2α. 8-iso-15-keto PGF2α is a vasoconstrictor when tested on the rat isolated thoracic aorta, acting via the TP (thromboxane) receptor.

RWJ-56110 dihydrochloride is a potent, selective, peptide-mimetic inhibitor of PAR-1 activation and internalization (binding IC50=0.44 μM), showing no effect on PAR-2, PAR-3, or PAR-4.

RWJ-56110 dihydrochloride also blocks angiogenesis and the formation of new vessels in vivo, and induces cell apoptosis[1][2].

12(S)-HETE, a 12-lipoxygenase metabolite of arachidonic acid, is mitogenic for cancer cell proliferation and enhances angiotensin II-induced contraction of BLT2 (type 2 receptor in arteries of leukotriene B4 mice) and TP (thromboxane receptor)-mediated mechanisms. 12(S)-HETE promotes superoxide and isothromboxane-like metabolites in arterial endothelial cells. production.
