title: The inhibitory effect of bis[2-[(E)-2-octenoylamino]ethyl] disulfide on the cyclooxygenase pathway.
abstract: Bis[2-[(E)-2-octenoylamino]ethyl] disulfide (compd. I-3) inhibited collagen- and arachidonic acid-induced rat platelet aggregation, although not adenosine 5'-diphosphate (ADP)-induced rat platelet aggregation. Based on these results, we then investigated the inhibitory effect of compd. I-3 on thromboxane B2 formation from arachidonic acid in rat platelets, and prostaglandin I2 formation in rat aortae. Compound I-3 inhibited both thromboxane B2 and prostaglandin I2 formation, suggesting that it has an inhibitory effect on cyclooxygenase. The inhibitory effect of compd. I-3 was confirmed in experiments using a crude preparation of sheep seminal vesicle microsomal prostaglandin synthetase. These findings suggested that compd. I-3 has an inhibitory effect on cyclooxygenase activity, like nonsteroidal anti-inflammatory drugs.
