6-keto prostaglandin F1α (6-keto PGF1α) is the inactive, non-enzymatic hydrolysis product of PGI2. 6-keto PGF1α serves as a useful marker of PGI2 biosynthesis in vivo. When [3H]-PGI2 is injected into healthy human males, 6.6% of the radioactivity is recovered from urine as [3H]-6-keto PGF1α.
6-Ketoprostaglandin F1α is the stable hydrolysis product of prostacyclin (P839060), an eicosanoid which prevents the formation of platelet plugs and an effective vasodilator.
