Pathways of Eicosanoid Metabolism

Sponsor: Vanderbilt University

Summary

Prostaglandins are important signaling compounds formed from arachidonic acid. The enzymes that form prostaglandins, cyclooxygenase-1 and -2 are the targets of non-steroidal anti-inflammatory drugs (NSAIDs). Because prostaglandins are very unstable in the body, they can not be measured directly. Instead, their metabolites are isolated from urine or blood and quantified as markers of formation of the parent, active compounds. The investigators are testing the hypothesis that there is a previously unrecognized metabolic pathway between two prostaglandins. The investigators hypothesize that prostaglandin D2 (PGD2), in addition to its known metabolism to PGD-M, is also metabolized to 11-dehydro-thromboxane B2 (11-dehydro-TxB2).
