thromboxane

 [throm-bok´sān]
an intermediate in the metabolic pathway of arachidonic acid, formed from prostaglandin endoperoxides, and released from suitably stimulated platelets; the unstable form, thromboxane A2, is a potent inducer of platelet aggregation and constrictor of arterial smooth muscle.

throm·box·ane

(throm-bok'sān),
The formal parent of the thromboxanes; prostanoic acid in which the -COOH has been reduced to -CH3 and an oxygen atom has been inserted between carbons 11 and 12.

thromboxane

/throm·box·ane/ (-bok´sān) either of two compounds, one designated A2 and the other B2. Thromboxane A2 is synthesized by platelets and is an inducer of platelet aggregation and platelet release functions and is a vasoconstrictor; it is very unstable and is hydrolyzed to thromboxane B2.

thromboxane

(thrŏm-bŏk′sān)
n.
Any of several compounds, originally derived from prostaglandin precursors in platelets, that stimulate aggregation of platelets and constriction of blood vessels.

thromboxane

any of several compounds synthesized by platelets and other cells that cause platelet aggregation and vasoconstriction.

thromboxane (thrôm·bôkˑ·sān),
