Thromboxane - Wikipedia, the free encyclopedia - 0 views

  •  
    Thromboxane is a member of the family of lipids known as eicosanoids. The two major thromboxanes are thromboxane A2 and thromboxane B2. Thromboxane is named for its role in clot formation (thrombosis).

Thromboxane B2 - Wikipedia, the free encyclopedia - 0 views

  •  
    Thromboxane B2 is an inactive metabolite/product of thromboxane A2. It is almost completely cleared in the urine. It itself is not involved in platelet activation and aggregation in case of a wound, but its precursor, thromboxane A2, is. Thromboxane A2 synthesis is the target of the drug aspirin, which inhibits the COX-1 enzyme (the source of thromboxane A2 in platelets).

Thromboxane A2 - Wikipedia, the free encyclopedia - 0 views

  •  
    Thromboxane A2 (TXA2) is a thromboxane. It is generated from prostaglandin H2 by thromboxane-A synthase. It is also a major component of blood clots. Aspirin irreversibly inhibits platelet cyclooxygenase 1 preventing the formation of prostaglandin H2, and therefore thromboxane A2. TXA2 is very unstable in aqueous solution, since it is hydrolyzed within about 30 seconds to the biologically inactive thromboxane B2. Due to its very short half life, TXA2 primarily functions as an autocrine or paracrine mediator in the nearby tissues surrounding its site of production.

Prostacyclin - Wikipedia, the free encyclopedia - 0 views

  •  
    Prostacyclin (or PGI2) is a member of the family of lipid molecules known as eicosanoids.\nAs a drug, it is also known as "epoprostenol".[1] The terms are sometimes used interchangeably Prostacyclin (PGI2) chiefly prevents formation of the platelet plug involved in primary hemostasis (a part of blood clot formation). It is also an effective vasodilator. Prostacyclin's interactions in contrast to thromboxane (TXA2), another eicosanoid, strongly suggest a mechanism of cardiovascular homeostasis between the two hormones in relation to vascular damage.

Cyclooxygenase - Wikipedia, the free encyclopedia - 0 views

  •  
    Cyclooxygenase (COX) is an enzyme (EC 1.14.99.1) that is responsible for formation of important biological mediators called prostanoids (including prostaglandins, prostacyclin and thromboxane). Pharmacological inhibition of COX can provide relief from the

Eicosanoid - Wikipedia, the free encyclopedia - 0 views

  •  
    In biochemistry, eicosanoids are signaling molecules derived from omega-3 (ω-3) or omega-6 (ω-6) fats. They exert complex control over many bodily systems, especially in inflammation, immunity and as messengers in the central nervous system. The network
