I-BOP is an agonist (KD=0.61 nM) at the thromboxane A2 receptor (TP). I-BOP promotes cell proliferation by activating the PI3K pathway in vascular smooth muscle.

I-SAP is a high affinity TP receptor antagonist. At physiologic pH, I-SAP produces platelet shape change, but not aggregation, with an EC50 value of 9.7 nM. I-SAP binds to human platelets with the maximum binding obtained between pH 6.5 and pH 7.4. In washed human platelets, the Kd for I-SAP is 468 pM at pH 7.4 and 490 pM at pH 6.5.

8-iso PGF3α is an isoprostane produced from the free-radical peroxidation of EPA. While little is known about its biological activity, one report indicates it is inactive in a TP receptor-mediated assay of human platelet shape change, a test in which 8-iso PGF2α has an ED50 value of 1 uM. [1]

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.

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.

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.

The prostaglandin E receptor 4 (EP4) is one of four G protein-coupled receptors that mediate the actions of prostaglandin E2 . Binding of PGE2 to the EP4 receptor causes an increase in intracellular cyclic AMP, which plays important roles in bone formation and resorption, cancer, and atherosclerosis. KMN-80 is a substituted γ-lactam (pyrrolidinone) derivative of PGE1 that acts as a selective and potent agonist of EP4 with an IC50 value of 3 nM (IC50 = 1.4 μM for EP3 and > 10 μM for all other prostanoid receptors). In functional assays it has been shown to stimulate secreted alkaline phosphatase gene reporter activity in EP4-transfected HEK293 cells with an EC50 value of 0.19 nM, demonstrating >5,000 and 50,000-fold selectivity against EP2 and TP, respectively. KMN-80 can induce the differentiation of bone marrow stem cells from both young and aged rats into osteoblasts in vitro (EC50s = 20 and 153 nM, respectively) and exhibits favorable tolerability up to at least 10 μM, whereas the EP4 agonist L-902,688 is highly cytotoxic at similar concentrations in these cells. KMN-80 has been used to repair calvarial defects in an in vivo rat craniomaxillofacial reconstruction model (rate of reduction in defect size equivalent to BMP-2 treated rats) and to promote bone formation in a rat incisor tooth socket model.
