Daflon is under preliminary research for its potential use in treating vein diseases, [5] or hemorrhoids. [6] It is sold as a drug in France, [7] [8] Spain, [9] Malaysia [10] [11] and Belgium. There is moderate certainty evidence for the effectiveness of daflon for slightly reducing oedema compared to placebo in the treatment of chronic venous ...
Thromboxane A2 Thromboxane B2. Thromboxane is a member of the family of lipids known as eicosanoids. The two major thromboxanes are thromboxane A2 and thromboxane B2. The distinguishing feature of thromboxanes is a 6-membered ether-containing ring. Thromboxane is named for its role in blood clot formation .
Thromboxane A 2 (TXA 2) is generated from prostaglandin H 2 by thromboxane-A synthase in a metabolic reaction which generates approximately equal amounts of 12-hydroxyheptadecatrienoic acid (12-HHT). Aspirin irreversibly inhibits platelet cyclooxygenase 1 preventing the formation of prostaglandin H 2, and therefore TXA 2.
U46619 is a stable synthetic analog of the endoperoxide prostaglandin PGH 2 first prepared in 1975, [1] and acts as a thromboxane A 2 (TP) receptor agonist. It potently stimulates TP receptor-mediated, but not other prostaglandin receptor-mediated responses in various in vitro preparations and exhibits many properties similar to thromboxane A 2, including shape change and aggregation of ...
Thromboxane A2 synthesis is the target of the drug aspirin, which inhibits the COX-1 enzyme (the source of thromboxane A2 in platelets). [1] 2-(3,4-Di-hydroxyphenyl)-ethanol (DHPE) is a phenolic component of extra-virgin olive oil. An olive oil fraction containing DHPE can inhibit platelet aggregation and thromboxane B2 formation in vitro. [2]
11-Dehydrothromboxane B2 (or 11-dehydro-TXB2) is produced from the breakdown of thromboxane A2.It is released by activated platelets and urine levels of 11-dehydro-TXB2 can be used to monitor the response to aspirin therapy when used to prevent heart disease [1] and in diseases where platelet activation is prominent.
Cyclooxygenase (COX), officially known as prostaglandin-endoperoxide synthase (PTGS), is an enzyme (specifically, a family of isozymes, EC 1.14.99.1) that is responsible for biosynthesis of prostanoids, including thromboxane and prostaglandins such as prostacyclin, from arachidonic acid.
The thromboxane receptor (TP) also known as the prostanoid TP receptor is a protein that in humans is encoded by the TBXA2R gene, The thromboxane receptor is one among the five classes of prostanoid receptors [5] and was the first eicosanoid receptor cloned. [6] The TP receptor derives its name from its preferred endogenous ligand thromboxane A ...
