This test was carried out according to the modified method of Silver (Science, 183, 1085, 1971). Male test white rabbits were used as test compounds of approximately 3 kg of live weight.
Each group of rabbits was orally administered with the test compound at the appropriate dose, and then 1 hour after oral administration, 1.3 mg / kg of arachidonic acid was administered intravenously to each one. Then test animals were observed and sudden deaths were recorded during the test period, ED was determined i by the Probit method.

the activity of the known compound Daeoxiben,
These results demonstrate that the compounds of the invention inhibit thromboxane synthetase by blood platelet microsome in mammals, including humans, and also demonstrate a high and specific inhibitory activity against TXA biosynthesis. Biosynthesis of TXA can be inhibited by up to 50% by concentration of compounds in the order of 10 mol. However, the compounds of the invention possess very weak inhibitory activities against cyclooxygenase and prostacyclin synthetase and therefore do not inhibit the synthesis of other prostaglandin derivatives.
