Natural Product Identification
Common NameThromboxane B3
DescriptionThromboxane B3, also known as TXB3, belongs to the class of organic compounds known as thromboxanes. These are eicosanoids structurally characterized by the presence of a 6-member ether containing ring. Thus, thromboxane B3 is considered to be an eicosanoid lipid molecule. All eicosanoids function locally at the site of synthesis, through receptor-mediated G-protein linked signalling pathways. Thromboxane B3 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. The PGs and TXs are collectively identified as prostanoids. Prostanoids are local-acting mediators formed and inactivated within the same or neighbouring cells prior to their release into circulation as inactive metabolites (15-keto- and 13,14-dihydroketo metabolites). Prostanoids take part in many physiological and pathophysiological processes in practically every organ, tissue and cell, including the vascular, renal, gastrointestinal and reproductive systems. Thromboxane B3 was first documented in 1985 (PMID: 2996649). These molecules are extremely potent, able to cause profound physiological effects at very dilute concentrations.
