描述
Thromboxane is a member of the family of lipids known as eicosanoids. It is produced in platelets by thromboxane synthetase, which is produced from the endoperoxides by the cyclooxygenase (COX) enzyme from arachidonic acid. -- Wikipedia; Thromboxane is a vasoconstrictor, potent hypertensive agent, and facilitates the clumping of platelets. It is in homeostatic balance in the circulatory system with prostacyclin, a related compound. The widely-used drug aspirin acts by inhibiting the ability of the COX enzyme to synthesize the precursors of thromboxane within platelets. -- Wikipedia
Thromboxanes are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs) and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes) and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent, able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis, through receptor-mediated G-protein linked signaling pathways. [HMDB]
