Inhibition of prostaglandin biosynthesis by 7-oxa- and 5-oxa-prostaglandin analogues (Short Communication)

Abstract
Some oxaprostaglandin derivatives have been shown to inhibit prostaglandin biosynthesis from arachidonate by a particulate prostaglandin synthetase preparation. The most potent inhibitor was 5-oxaprost-13-trans-enoate, and inhibition by this compound appeared to be competitive. Certain structure–activity relationships were ascertained.
