<biochemistry> Arachidonic acid metabolites produced by the action of thromboxane synthetase on prostaglandin cyclic endoperoxides. Thromboxane A2 (TxA2) is a potent inducer of platelet aggregation and release and although unstable, the activation of platelets leads to the further production of TxA2. Also causes arteriolar constriction. Another endoperoxide product, prostacyclin, has the opposite effects.
