thromboxanes

throm·box·anes

(throm-boks'ānz), A group of compounds, included in the eicosanoids, formally based on thromboxane, but with the terminal COOH group present; biochemically related to the prostaglandins and formed from them through a series of steps involving the formation of an endoperoxide (an O-O bridge between carbons 9 and 11 in the prostaglandins) by a cyclooxygenase, followed by a rearrangement (catalyzed by thromboxane synthase) that inserts one of the two oxygen atoms between carbons 11 and 12, leaving the other still bridging carbons 9 and 11. Thromboxanes are so named from their influence on platelet aggregation and the formation of the oxygen-containing six-membered ring (pyran or oxane). Like the prostaglandins, individual thromboxanes (abbreviated TX) are designated by letters (A, B, C, etc.) and subscripts indicating structural features.

throm·box·anes

(throm-bok'sānz) A group of compounds, included in the eicosanoids, formally based on thromboxane, but with the terminal COOH group present; biochemically related to the prostaglandins and formed from them. Thromboxanes are so named from their influence on platelet aggregation and the formation of the oxygen-containing six-membered ring (pyran or oxane). Like the prostaglandins, individual thromboxanes (abbreviated TX) are designated by letters (A, B, C, and onward) and subscripts indicating structural features.

thromboxanes

Substances similar to the prostaglandins that promote blood clotting. Aspirin in small doses reduces the production of thromboxane by PLATELETS.
