A pyridine group was linked to the tetrahydronaphthalene moiety of the derivatives described in the preceding paper, to afford new combined thromboxane receptor (TP-receptor) antagonists and synthase inhibitors. The most interesting compound 2f inhibits TXA2 synthase with an IC50 value of 0.64 microM and the aggregation of human platelets with an IC50 ...

Thromboxane A2 (TXA2) plays a pivotal role in platelet activation and is involved in the development of thrombosis. Thromboxane synthase inhibitors suppress TXA2 formation and increase the synthesis of the antiaggregatory prostaglandins PGI2 and PGD2; however, accumulated PGH2 may interact with the platelet and vessel wall TXA2 receptor, thus reducing ...

The regulation of plasma renin activity (PRA) by thromboxane (Tx) A2 was studied in anesthetized rats by measuring PRA before and after administration of drugs that block cyclooxygenase (CO) (indomethacin [INDO], 5 mg/kg), thromboxane synthase (TS) (UK 38485 [UK], 100 mg/kg), or Tx receptors (SQ 29548 [SQ], 8 mg/kg or L 641953 [L], 50 mg/kg) or that ...

Characterization of glomerular thromboxane receptor sites in the rat
American Journal of Physiology-Renal Physiology, 1989The aim of this study was to identify and characterize thromboxane (Tx) receptor sites in renal glomeruli. Binding studies were performed on freshly isolated glomeruli using the stable TxA2 receptor antagonist, [3H]SQ 29548. Specific binding was saturable, reversible, and varied with glomerular protein.

Cell signalling through thromboxane A2 receptors
Cellular Signalling, 2004Thromboxane A2 receptors (TPs) are widely distributed among different organ systems and have been localized on both cell membranes and intracellular structures. Following the initial cloning of this receptor class from human placenta, the deduced amino acid sequence predicted seven-transmembrane spanning regions, four extracellular domains and four ...

Thromboxane receptor signalling in human myometrial cells
Prostaglandins & Other Lipid Mediators, 2002We measured the effects of stable thromboxane A2 (TXA2) analogues on signalling in cultured human myometrial cells. U46619 and/or IBOP stimulated total inositol phosphates (IPs) and cAMP production, RhoA-associated protein kinase (ROK) activity and elevated intracellular calcium [Ca2+]i.
