[Activity of rabbit heart on thromboxane synthetase].
The soluble and microsomal fractions of Rabbit myocardium are not able to induce the synthesis of thromboxanes. On the contrary, they inhibit the thromboxane synthetase of various sources. The chemical structure of the active constituent responsible for this activity is not yet known: it is probably neither of an enzymatic nature, nor a protein of high molecular weight.
