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.

Angoroside C is a Potential anti-inflammatory compound. Inhibitor of prostaglandin E2 release in mouse peritoneal macrophages in vitro. Shows potent antioxidative activity in reducing the oxidized OH adducts of dAMP and dGMP. Reveals some trypanocidal potential.

p-Hydroxycinnamic acid (NSC-59260) can inhibit platelet activity, with IC50s of 371 μM, 126 μM for thromboxane B2 production and lipopolysaccharide-induced prostaglandin E2 generation, respectively.

Tebufelone is a potent in vitro inhibitor of CO , a novel non-steroidal anti-inflammatory drug (NSAID) belonging to the di-tert-butylphenol (DTBP) class that has shown potent anti-inflammatory, analgesic and anti-reticulitis properties in various animal models. Tebufelone potently inhibits the formation of prostaglandins (PGE2) and blocks the formation of lipoxygenase pathway products [leukotriene (LTB4)] in rat macrophages (IC50 = 20 microM) and human whole blood (IC50 = 22 microM) in vitro. = 20 microM) and human whole blood (IC50 = 22 microM) from the formation of lipoxygenase pathway products [leukotriene (LTB4)] in vitro.

Evodiamine (d-Evodiamine) is an alkaloid isolated from the fruit of daylily and has a variety of biological activities including anti-inflammatory, anti-obesity and anti-tumor.

Timapiprant (OC000459) is a potent and selective D prostanoid receptor 2 (DP2) antagonist (IC50: 13 nM).

2-Acetylbenzoic acid is more potent than 2-propionyloxybenzoic acid in inhibiting platelet function and platelet prostaglandin (PG) synthesis although the potencies of these agents were comparable in inhibiting prostacyclin (PGI2) synthesis.

PF-04418948 is a potent EP2 receptor antagonist (IC50 = 16 nM for human EP2 receptors). Displays over 2000-fold selectivity for EP2 receptors over EP1, EP3, EP4, DP1 amd CRTH2 receptors; exhibits <30% binding at a diverse panel of GPCRs and ion channels at a concentration of 10 μM. Inhibits PGE2-induced increases in intracellular cAMP; reverses PGE2-invoked relaxation of mouse trachea (IC50 = 2.7 nM).
